Featured Listing: 1978 Kawasaki Z1R TC

In the wonderful world of Turbo motorcycles, there are the "make your own" types, and the factory turbo offerings. But this special model, the mighty Kawasaki Z1R TC, not only blurs the lines between the two camps, it is also the very first in the factory turbo column. You see, the Z1R TC was sold through Kawasaki dealerships as a new model. However it was not (technically) a factory effort. The offspring of a mixed marriage, ex-Kawi exec Alan Masek convinced the Big K brass to ship bikes to his Turbo Cycle Company (TCC). Given the sluggish sales of the warmed over Z1R, this was no big feat. TCC applied an American Turbo Pak kit to the stock machines, and shipped the resultant mutants to select dealerships with a $1,400 premium tacked on to the sticker price. Appearing to be a factory effort - but devoid of the factory warranty - the Z1R TC went on to gain an incredible reputation for speed, on/off switch turbo boost behavior (Jeckyl & Hyde anyone?), and questionable longevity. For Kawasaki it was a huge win with very little risk. Today, these rare bikes are coveted by collectors world wide.

Featured Listing: 1978 Kawasaki Z1R TC!

The original Z1R TC bikes went out the door in stock Kawasaki colors; they were literally converted by TCC and kicked out of the shop. As the operation matured, several changes occurred. The first was a change to the exhaust plumbing and collector - in an effort to tame the boost. The next change was a new wastegate that limited boost to 6 PSI (the Gen I bikes had a fully adjustable wastegate). And finally the classic 1970s paint scheme emerged. These are all Gen II bikes, and can be identified by the "Molly Designs" logo on the tail section. With the new graphics the Z1R TC finally had the appearance to show off the induction upgrades. Today these Molly graphic bikes are the most desired of the Z1R TC set.

From the seller:
You should know that I am a serious collector, with a large motorcycle collection. I decided to sell some of the most valuable motorcycles in the collection. These motorcycles represent some of the most iconic motorcycles 1970s, 1980s, and 1990s. Those motorcycles are now being offered up for sale one by one. Many years ago when the best of the best was available, and that is what I was buying, these motorcycles were targeted for my collection by me.

In general, I do believe super rare Italian motorcycle of the 1970s and 1980s are the future Ferrari of motorcycle collecting. We all know what has happened with the Ferrari market.

An exception is the Kawasaki Z1RTC.

More from the seller:
The rare bike in this ad is the 1978 Kawasaki Z1RTC. To me it is one of the greatest and rare motorcycle you can collect. It is a very limited production motorcycle especially in the Molly Graphics configuration. It is unbelievably fast and has an exhaust that is a thrill to listen to as it winds up through the gears. I purchased this Z1RTC from the original owner and it has not been taken apart or restored or manipulated. The original owner explained to me that this ZR1TC turbo is a Stage 3 which is the best of the best for Z1RTC turbos. The original owner told me he took the bike to a drag strip only once and turned 9.9 seconds in the quarter mile and described the feeling by saying, “it felt like his eyeballs were pinned to the back of his head”

The Z1RTC is all original except for the upgraded pressure gauge. Always kept on a trickle charger and ready to fly down the road.

They are only original once.

I would suggest that you check out the other rare cycles that I am offering for sale.

Thanks for looking at one of the best!

While the Z1R TC put Kawasaki on the map, not all was tea and roses. This was a serious motorcycle that demanded the best riders. Boost was not easily manipulated and the remainder of the stock Z1R pieces were not engineered for the upgrade. The complete lack of engine controls that we take for granted (computer controlled fuel injection, programmable ignition modules, rev limiters) made for a very fragile existence. There was actually recommendations in the manual that new owners upgrade to stronger valve springs, weld the crank and upgrade the clutch if the bike were to be used aggressively. When was the last time your owners manual made those types of modification suggestions? But given that there was no factory warranty, there was apparently little to lose.

These are mean, aggressive yet beautiful motorcycles. They chronicle an era where experimentation and entrepreneurship could coexist with a larger factory effort. And the epic bikes that resulted from these strange bedfellows strike awe and wonder in the hearts and minds of viewers - and riders. To find a totally stock Z1-R TC is an amazingly rare sight. This bike is very, very close to perfectly original, and has a very limited list of owners. It looks absolutely pristine and clean enough to eat off of - should you dare to commit such sacrilege. For those in the market for something unique and special, few bikes can compete with this beautiful 1978 Kawasaki Z1R TC. Interested readers should give Joe a call ASAP. If previous listings of this model are any example, this one will go quickly. Boost on, and good luck!!

Update 3.15.2019: Now relisted on eBay with a buy-it-now of $37,900. Good luck to buyers and seller! Links updated. -dc

Before Honda and Suzuki engineered machines with turbocharged engines in the early part of the 1980s, Kawasaki pioneered the idea by using forced induction to make their musclebound Z1R a truly brawny street machine. By 1978, the thing was looking a little long in the tooth, and Kawi saw turbocharging as an effective shot in the arm. It was, but in true Kawasaki fashion, it was about as crude and brutal an execution as you could imagine. Instead of designing the engine in-house, and building a bike around it, they farmed out the modifications and made the TC a dealer-installed option.

That meant the turbo blew compressed air into a stock bottom end and the stock chassis, suspension and brakes were expected to make do. The Z1-R TC pushed out something like 130 horsepower in an era when air-cooled 1000s were usually content with somewhere around 90. The black and orange Molly graphic-sporting TC went on to become an icon, though only about 220 left showrooms. All things considered, that was likely for the best.

This 1978 Kawasaki Z1-R TC has had a nut-and-bolt restoration to better-than-new condition. The pictures speak louder than I can, but it has apparently been made perfect and original down to the grips. We're not sure how many TCs are left, but we'd stake money that this is one of the nicest.

From the eBay listing:

1 OF ONLY 220 1978 KAWASAKI KZ1000 Z1R-TC/TC2 TURBO's EVER PRODUCED. THIS ONE IS COMING OUT OF MY PRIVATE COLLECTION. IT IS A DOCUMENTED LOW MILEAGE ORIGINAL BLACK MOLLY TC-2. MYSELF AND 2 INTERNATIONAL AWARD WINNING RESTORATION EXPERTS SPENT OVER A YEAR RESTORING HER TO ABSOLUTE ORIGINAL MUSEUM QUALITY (THE CORRECT GRIPS WERE INSTALLED AFTER PHOTOS). NO EXPENSE WAS $PARED! THANK GOD MY WIFE DID'NT SEE THE EXPENSE LIST.

MOST OF THE BOLTS, SCREWS, NUTS AND WASHERS ARE NEW OLD STOCK AS I HAVE A VERY EXTENSIVE "NOS" INVENTORY), ALONG WITH COUNTLESS OTHER PARTS.

THIS BIKE WAS OWNED AND RIDDEN IN THE SOUTH FLORIDA AREA THRU THE LATE 1980's. I ACTUALLY WORKED ON THIS BIKE AT KAWASAKI SUZUKI OF FT. LAUDERDALE IN 1987 ( I WAS THE CHIEF MECHANIC). THEN IT MADE ITS WAY TO ANOTHER COLLECTOR THAT KEPT IT IN A COOL CLIMATE ENVIRONMENT UNTIL I ACQUIRED IT A FEW YEARS YEARS AGO.

IF YOU ARE UNAWARE OF THE HISTORY OF THE Z1R TURBO, IN 1978 KAWASAKI PARTNERED WITH WITH ONE OF THERE FORMER EXECUTIVES WHO HAD FORMED TURBO CYCLE CORPORATION TO CREATE THE WORLDS FIRST FACTORY TURBO MOTORCYCLE. KAWASAKI's MISSION WAS TO BOOST SALES OF THE Z1R BY MAKING IT THE FASTEST BIKE OF THE TIME. IN 1979 TO FURTHER DRIVE SALES, KAWASAKI CONTRACTED WITH ROLLIN "MOLLY" SANDERS TO COME UP WITH THE SINISTER BLACK PAINT SCHEME. ONLY 220 1978/1979's (some of the 1978 line came out as 1979 on the mso/tittle) WERE PRODUCED IN THE SECOND AND FINAL YEAR.

ENGINE: #006435 IS THE BIKES ORIGINAL LOW MILAGE ENGINE THAT WAS UPGRADED WITH ALL THE NEEDED MODS BACK IN THE EARLY 80s. I COMPLETELY WENT THRU THE ENGINE TO VERIFY, INSPECT/REPLACE AS NEEDED. IT HAD A WELDED, BALANCED CRANKSHAFT, UNDERCUT TRANSMISSION, UPGRADED OIL PAN, HEAVY DUTY CLUTCH ASSY, FORGED PISTONS, NEW RINGS, PERFORMANCE VALVE JOB, SHIMS UNDER BUCKETS, AND APE HARDWARE. THE BENDIX CARB AND TURBO CHARGER/WASTE GATE OVERHAULED. ALL NEW SEALS AND GASKETS. NEW DYNA S IGNITION AND NEW COILS. THE EXHAUST WAS STRIPED AND RE-CHROMED TO BETTER THEN NEW SPECS. THE ENGINE RUNS LIKE IT DID IN 1979.

FRAME: HAS BEEN STRIPED AND REPAINTED TO OEM SPECS. THE FRONT FORKS REBUILT WITH THE LOWER LEGS PROPERLY REFINISHED TO OEM STANDARDS. THE REAR SHOCKS WERE NOS. THE MOLLY CONCEPTS BLACK MOLLY PAINT IS THE ORIGINAL THAT HAS BEEN
RE-CLEARED TO BRING BACK THE ORIGINAL DEEP LUSTER. THE WHEELS WERE DISASSEMBLED AND REPAINTED/POLISHED TO OEM SPECS. SHE IS FITTED WITH NEW METZLER TIRES "SEMI PERIOD-CORRECT". THE BRAKES WERE COMPLETELY OVERHAULED. THE SEAT IS THE ORIGINAL SEAT FROM THE BIKE AND IS IN AMAZING CONDITION. THE WINDSCREEN AND SEAL ARE NOS AS ARE THE LEVERS AND MIRRORS AND MORE COMPONENTS THEN I CAN LIST. I WILL BE INSTALLING THE CORRECT VERY HARD TO FIND NOS GRIPS. NOTE THE VERY EXPENSSIVE AND IMPOSSIBLE TO FIND "NOS" ATP BOOST GUAGE THE ORIGINAL HAD THE USUAL CRACKED GLASS.

I HAVE BEEN COLLECTING, RESTORING, FIXING, RIDING, AND RACING MOTORCYCLES SINCE GRADUATING FROM AMERICAN MOTORCYCLE INSTITUTE "AMI" IN DAYTONA FL. IN 1980. I OWN 3 BLACK MOLLY TC-2's AND 2 BLUE TC's BUT THIS IS BY FAR THE NICEST IN MY COLLECTION, WORTHY OF BEING IN THE BARBER MUSEUM. ONLY SELLING IT TO MOTIVATE ME TO RESTORE THE NEXT ONE.

PLEASE ASK QUESTIONS I AM SURE I LEFT OUT SOMETHING ELSE WE DID SINCE WE DID SOOOOOO MUCH.

If the stories of this machine's power and handling are to be believed, the scant mileage isn't much of a surprise. Given its rarity, lunacy and historical significance, there's a lot of value in this bike. The auction has active bidding and a few days left, so act quickly if this Z1-R TC is going to be yours.

Puffed Up: 1978 Kawasaki Z1-R TC

In the 1970s the Kawasaki Z1 was the big dog of the sporting world. Long in the tooth as the decade neared to a close (the Z1 platform was introduced way back in 1972), Kawasaki introduced an updated model - the Z1-R. Largely a warmed-over refresh rather than an all new design, the R model had the looks to help it along in the showroom, but lacked the technology, refinement and performance that competitors were offering. Enter a unique partnership between Alan Masek and his newly formed Turbo Cycle Company and Kawasaki. Masek was a former Kawasaki executive - and knew that the Z1-R was faltering in the showroom. That meant there was a stockpile of bikes that Kawasaki couldn't sell. By marrying these unsold units to an American Turbo Pak kit and selling the bikes through the dealership network, Kawasaki was able to put itself back into the horsepower game with relatively low risk. Thus the Z1-R TC was born.

1978 Kawasaki Z1-R TC for sale on eBay

Beneath the sticker kit, the TC model was all Z1-R. Same brakes, suspension, controls, engine and trans. Outside of the bolt-on turbo and boost gauge, wastegate and associated piping, there wasn't much else. Your $1,400 premium to the already expensive Z1-R bought you graphics and outrageous horsepower. And voided your warranty. And while the Z1 platform was robust for its time, the lack of any engine controls (no fuel injection, no rev limiter, etc) meant that you were only one missed shift away from mechanical catastrophe. Keep in mind that all other engine internals were shared with the standard Z1-R. Therefore it was suggested that new owners upgrade to stronger valve springs, weld the crank and upgrade the clutch if the bike were to be used aggressively. Did I mention it also voided the warranty?

From the seller:
This 1978 kawasaki Z1RTC bike is one of 220 made and sold through kawasaki dealers. This bike is in good original condition and has had several new oem parts. Bike has been stored in climate control house garage. Lights and turn signals horn and other electronics work including the fuel and amp gauge. This bike has not been repainted. Worse thing on it is the fuel tank does have some light few chips in the paint by the neck. The engine cases are the original ones for the bike. It does have brand new correct size tires on it. New battery also. It is ready to ride. The motor has been rebuilt with new gaskets, seals and new paint on the cases. They are the only thing that has been painted. Has correct gas valve and wind screen. The seat is in excellent shape and comes with the hard to find kicker, the rubber is there for it but I do not have the bracket to hold it. Brakes have been all rebuilt front and back with hard to find parts.the turbo is in excellent shape also.

The wild paint scheme you see here was introduced on the second generation of TC bikes. These are identified by the "Molly Designs" logo on the tail section. Numerous small upgrades were incorporated on the Gen II bikes, including an upgraded collector and exhaust system, and a factory-limited wastegate (now set at 6 PSI, rather than adjustable). This was all in the name of making the bike more rider friendly, and to aid in the ultimate longevity of the mechanicals. And while the TC was certainly fast, it was by no means a showroom winner. Sure, it gave Kawasaki street creds and horsepower bragging rights - but it was a "for experts only" motorcycle that commanded a serious premium. Many were pressed into service as drag bikes - and endured a difficult life full of breakages and modifications. Today finding a totally clean and stock Z1-R TC is a rare sight.

This particular 1978 Z1-R TC looks to be in pretty nice shape. Wearing original paint and still holding onto the stock boost gauge, decals and info plates, the bike looks very close to original. The engine has been gone through (not surprising given the age and the history of the model), but no information as to any potential internal upgrades (i.e. welded crank, etc). With fewer than 10,000 miles, this forty-something year old wonder is looking for a new home. This is an iconic motorcycle in the annals of turbo charging, as it was the first TC bike that was officially offered by a major manufacturer (even if it was a partnership and not a full fledged in-house model). Prices for these bikes continue to rise, given the rarity and importance of the model. This particular one jumped quickly above $12k - with more to come and reserve still in place. Check it out here, and then jump back to the comments and share your thoughts on turbos. Good Luck!!

Use Your Boost to Get Through – 1983 Suzuki XN85 Turbo

Vying for additional power without displacement, the 1980's saw major cycle makers attempt to tailor the excess heat and complexity of turbocharging to sport bikes.  Suzuki's entry is the rarest and this one has ultra-low mileage, and just one tangle with the mischievous elves that tip stuff onto parked motorcycles.

1983 Suzuki XN85 Turbo for sale on eBay

Suzuki based their turbo on a 673cc inline four, and used electronic fuel injection to tailor the fuel delivery through the variable throttle / boost map.  85 hp are claimed, leading to the model designation.  An early adopter of innovations like Full-Floater rear suspension, air-oil cooling system ( with piston squirters ), and 16-inch front wheel, the XN85 was a bit of a tech showcase.  Kayaba provided the suspension, with anti-dive forks.  Triple disks are big but not oversize considering the 550 lb. ready-to-ride weight.  Angular fairing and sculpted tank owe royalties to the then-recent Katana.

Detailed photos should be part of an auction with a high falutin' buy-it-now, which this eBay bike parts dealer probably knows.  Nothing a pre-purchase inspection can't remedy, however.  Some history and service record(s) would be a help, even for a bike with so many years and so few miles.  Short and sweet from the eBay listing:

483 miles - all original except petcock, last ran in December 2018. Also, have Service Manual, and original title.
Right rear tail section has scratches that can be fixed.

Suzuki's turbo was the sportiest of the big four's litter, though even at that it's more of a GT.  None were real showroom success stories, but maybe their role was more of leading edge glitterati for the dealer.  Under just the right conditions, the XN85 could woosh through the traps first, or just look great on the sidestand.  Either way the XN85 can provide liter-size performance from a boosted mid-size, and maybe the make offer button will let us know whether this is a survivor or museum piece.

Power Play: 1983 Honda CX650 Turbo

The 1980s represented a wild period for motorcycle manufacturers. Everyone was throwing technology at the performance problem, and all Big Four vendors went full speed down the Turbo road. Little did they know it would be a dead end street. But while it lasted, the glorious promise of liter-bike power in a mid-sized motorcycle ruled the day. The mighty technological giant know as Honda was both the first - and the last - reveler at the boosted party, and built what many consider the most complete factory Turbo bike offered. Enter today's rarity, the mighty 1983 Honda CX650 Turbo. Long since known as the roll-on king, the CX650T produced real-world, usable power in a whooshing rush that was unmatched by contemporaries. Offered for one scant year at a princely price, the 650 Turbo (just like the CX500 Turbo) failed to capture much wallet share of the riding public, and was discontinued. With it, the Turbo era was over.

1983 Honda CX650 Turbo for sale on eBay

Externally the CX650T resembles a futuristic Silver Wing, and the apple didn't fall too far from that tree. Utilizing a slightly beefed up bottom end, the Turbo model makes due with many of the CX infrastructure elements - which should tell you how over built the CX lineup was in the first place. A single turbo blows through the four valve heads. Fueling is provided courtesy of computerized injection (hot and heavy stuff back then). Optimizing for torque rather than peak HP, the 650 is good for about 100 HP. But this is no drag racer. With shaft drive, air suspension, a heavy chassis, a beefy motor, nearly a of ton of electronics and the large fairing, the CX650 Turbo tips the scales significantly on the wrong side of 550 lbs. Honda wisely chose the "sport touring" theme with their Turbo bikes, partly due to necessity of packaging everything up.

From the seller:
17 mile cx650 turbo tiltle is in my name. This bike will need serviced..it does run and drive .i tested it and put 10 miles on it my self Oem stock tools ,air gauge ,owners manual,stock Oem tires with nubs
Front rear,only thing on this bike not Oem it the glove box cover,other then that .this bike is as it was sold new.

Turbo bikes are rare. With only 1,700 and change of the 650s ever made (and a reported mere 1,000 or 1,200 imported to the US), these beasts are not common. This particular bike sports only 17 miles... total! Low mile Turbo bikes are more the norm than the exception, but this is an extreme example. The only specimens that have fewer miles are those machines donated by Honda to technical schools for training and learning (those were never intended to be titled or ridden). But miles are not to be feared on a CX650 Turbo. These are robust motorcycles with few real issues. The key gremlins on the bike are electrical related. Stators are no longer available and the cause of many a charging system's demise. Removable connectors under the seat can get corroded, run hot under load and can burn out. Other than those items, regular use will keep items such as the turbo waste gate operational and happy.

Turbo bikes have always been expensive relative to their same brand, non-boosted counterparts. That is part of the reason why they are rare; they simply were too expensive for the level of performance offered. And while they have been slow to appreciate (financial turbo lag?) they have been slowly climbing in price. Top condition, low mileage bikes are on the sharp end of the field - as is to be expected with any collectible. The seller is looking for an opening ask of $8,900, which thus far has scared away bidders. Nearly nine grand is a big ask for a CX650 Turbo in today's market, especially as this is the opening ask of an auction. These are wonderful and unique bikes that deserve a good look if you are searching for a rider/collector machine. This one is priced a little high when compared to others we have seen, but is certainly not in absurd territory. Check it out here, and then jump back to the comments and share your Turbo stories. Turbos need love too! Good Luck.

Explosive [Acceleration] Device: 1978 Kawasaki Z1R-TC Turbo for Sale

UPDATE: This bike sold before I could post it, but I'd thought I'd share it with you all anyway, since it is so darn nice. -Tad

The dream of the 1980s was to turbo all the things. Cars, hairdryers, sneakers... If you could buy it, someone was trying to slap a TURBO badge on it during the 1980s to help move units. Actual turbochargers started showing up on commonly-available vehicles during the 80s to inspire that trend, but people were experimenting with turbocharged passenger cars as far back as the Oldsmobile Jetfire, Chevy Corvair Corsa, and Saab 99 Turbo. It took a bit longer for turbocharging to find its way into the production motorcycling world, due to a few challenges associated with the relatively primitive turbo technology of the time. Of course, the term "production" might be stretching things a bit when you're talking about the Kawasaki Z1R-TC Turbo.

By 1978, the Kawasaki Z1R KZ1000 was decidedly old-fashioned, with honking big air-cooled four cylinder engine, a twin-shock rear suspension, spindly forks up front, and a frame that was less than cutting-edge. The package was generally competent and well-regarded, just a bit long-in-the-tooth. With the development of the much more modern GPz underway, Kawasaki needed to move some remaining stock and generate a bit of excitement for the brand. The TC Turbo, which took the already reasonably quick Z1R and added a RaJay turbo package that increased power by 50%, may have generated a little too much excitement.

TURBO was a word associated with power and speed and modern and cool, even if most people really didn't know what it meant, or exactly how a turbocharger added power to an engine. A high school buddy of mine drove his mom's Mitsubishi Tredia L equipped with some sort of POWER button on the automatic shifter, and he was convinced that it activated "turbo boost," since he'd watched lots of Knight Rider and thought that's how things worked... What it probably did was lock out overdrive in the transmission, but you couldn't convince him it didn't actually release additional power. And likely a great many enthusiasts' understanding of the technology didn't extend much beyond that.

Turbos can make big power, but with that great power comes great responsibility and it was laughably easy to adjust the wastegate on the Z1R TC to allow boost far beyond what the stock internals could handle, leading to a sudden, explosive reversal of the normal interior/exterior engine component relationship. Sure, you could always opt to have your new Kawasaki's engine fully built to withstand the additional pressures, something that was actually recommended by the company, but how many people do you think bothered to do that?

Turbochargers originally came into widespread use during World War II, and the advantages of forced-induction were exploited to allow combat aircraft to perform more efficiently at high altitudes, where reduced oxygen density significantly reduced power. The move towards turbocharging in automobiles was also driven by necessity in the 80s, when the manufacturers were hit by significantly increased fuel-economy and emissions standards. A turbocharger allowed smaller, more efficient engines to perform like larger engines on demand.

Unfortunately, while that Jekyl/Hyde personality of early turbocharged cars generally made them entertaining, it made motorcycles, especially ones already pushing the limits of frame and suspension technology, pretty terrifying: the Z1R probably would have killed more people than Cholera, but luckily very few were actually built. Even fewer still survive today, and most of those aren't in the hands of their original owners, who likely died horrible, firey deaths...

From the original eBay listing: 1978 Kawasaki Z1R Turbo for Sale

Created through an arrangement between Kawasaki and Turbo Cycle Corporation (which was founded by ex-Kawasaki Marketing Director, Alan Masek) brand new Z1R's were sent to TCC, who then modified them with a RaJay turbo and badging. These modified bikes were then sold through select Kawasaki dealers- without a warranty. THERE WERE ONLY 500 BUILT. 

The gas tank side covers, header panels, and tail section have been repainted and color matched to an original Z1R TC. It has all new decals from reproductiondecals.com. So much work has been done to this bike. There are approximately 40 miles on the top half of the rebuilt engine. the cylinder was removed, sand blasted, honed, and painted. New piston rings have been installed. I purchased a like new cylinder head that has all new component parts. The original head had two hairline cracks. The forks were removed, cleaned, and polished with new dust covers. It has a new battery. It has a rebuilt,older style Keihn carburetor. I have the original Bendix carburetor, but as most people know, it runs smoother with the Keihn carborator.

The Rajay turbo 370 F 40 was rebuilt by Mr. Turbo.  The seat has no rips or cuts. The seat pan was removed, sanded, primed, and painted with stock stickers installed from reproductiondecals.com. The bike starts, sounds, and runs great. I have all of the receipts from the mechanical work. Only if i feel you are very serious, I will provide you with the name of the motorcycle service center who performed the work on my bike and send you copies of the sales and receipts. Before the engine was rebuilt, I replaced the tires which are Pirelli Sport Demon. The sprockets and the brake pads were replaced. Those items have about 200 miles on them. The only item i know of that is not an original item is the Pingel fuel valve. Passed down from the original owner are the owners manual, turbo supplement manual, and black vinyl Kawasaki pouch, which was provided for Z1R TC conversions. Both manuals have all the pages intact, and are not oily or greasy. By the way, I know on Ebay, there are reproduction turbo supplement manuals, but this one is original. You can tell by the yellowing pages and semi brittle paper. All three items are 40 years old. 

This actual bike, and not one just like it, is pictured in a hard cover book written by Tony Sculpher title, "Kawasaki (K) Z1000 Z1-R." I have the book. I bought the bike from a collector of Z1R TCs. I wont divulge the info of the collector on ebay, due to privacy and legalities. I made a copy of the title while it was in his name, before I sent it to be transferred to my name. His name is in the book with a picture of my actual motorcycle above the description. All of the instrumentation works. The bike starts, sounds, and runs great. 

This bike's VIN is listed in the official Kawasaki registration for TCC bikes. I am posting a few photos, however, if you want more, please state the area of the bike that you want more detailed photos of. The frame VIN is KZT00D006472. The engine number is from the state police of California as it looks like there must have been an engine case issue which required a factory replacement. Replacement cases from Kawasaki do not carry an engine number and come blank. 

I will assist with your shipping, but will not be responsible for the shipping.

If you're in the market for a Z1R TC [and who isn't?] this looks like a good one. Unfortunately, as mentioned at the start, the listing has been pulled, so I'm assuming it "sold locally." It's clearly been owned by a knowledgeable enthusiast and, although it isn't sporting original paint, it appears to have been painstakingly restored. This is about as nice a machine as you're likely to find, with history, appropriate mechanical updates, and even a very comprehensive video with lots of commentary.
