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.

Featured Listing: 1978 Kawasaki KZ1000 Z1R for Sale

There are no points for second place. Unbeknownst to Kawasaki and Honda, both manufacturers were developing the Next Big Thing in the 1970s, an affordable, reliable, inline four-cylinder motorcycle displacing 750cc's. Unfortunately, Honda's CB750 was first to market by several months, leaving Kawasaki with the unenviable choice: be the also-ran, or delay their machine to come up with something special. The Z1 that followed may not have been first, but the 903cc engine meant its performance blew the CB750 into the weeds, and the Kawasaki Z1R seen here was an evolution of that muscular 70s machine.

Of course, by the time the Z1R was introduced, the overall package was pretty long-in-the-tooth, with a dual-shock rear suspension and spindly front forks. Most of the updates were cosmetic, with more modern, angular styling and cast wheels. Frame reinforcements and triple disc brakes improved handling and stopping, and a displacement bump to 1015cc took care of the straight-line performance enhancements. The 550lb wet weight and long wheelbase mean that it won't exactly carve corners, but that same long wheelbase should make it easy to blast away from stoplights in a howling cloud of tire and exhaust smoke.

While the Z1R may not have been cutting-edge when it was new, time has been kind to it and the crisp styling and classy silver-blue color look very sharp today. Like all 70s muscle bikes, the Z1R has definitely been increasing in value, perhaps as a result of its association with its even wilder sibling, the turbocharged Z1R TC. The seller refers to this as a "nut and bolt, frame-off restoration" and it certainly looks the part.

From the original eBay listing: 1978 Kawasaki KZ1000 Z1R for Sale

Coming out of my private collection (only because I just restored another 1978 Z1R) is my matching numbers 1978 Kawasaki Z1R with 9,300 original miles in pristine restored condition. This was a full nut and bolt, frame-off restoration with no expense spared, with over $20,000 in parts, labor, and paint refinishing.

The engine was completely disassembled and bead-blasted, then rebuilt to factory specifications with new: pistons, rings, camshafts, cam chain and adjuster, transmission undercut, multi-angle valve job, bearings, seals, carburetors were rebuilt and synchronized, all the hardware new old stock "NOS" or re-plated/zinced/re-chromed.

The frame was bead-blasted, treated, and powder-coated in a matching "OEM" black finish. The forks and brake calipers/master cylinders were completely rebuilt. The wheels were bead-blasted and powder-coated back to "OEM" standards with new tires, "NOS" cables, and wiring harness.

The bodywork was meticulously refinished using the "OEM" paint code and looks like it did when it sat on the Kawasaki showroom floor. The tank and side cover emblems are new old stock "NOS." The original Kawasaki 4-into-1 Z1R exhaust has been replaced with a very similar late 70s triple-chromed 4-into-1 exhaust that looks stock but sounds better. 

Every single part, nut, and bolt has either been replaced with new, rebuilt, or refinished to the highest "OCD" restoration standard. She looks, starts, and runs just like she did in 1978. Please don't hesitate to call or text me with any questions or concerns: 954-816-0806 Bob.

This immaculate, show-winning Z1R is worthy of any motorcycle museum, and will be your pride and joy, sitting in your private collection.

Don't miss out. Tell your wife these bikes are appreciating 15% or more each year and you can get it in time for Christmas.

Happy Holidays and Merry Christmas!

Honestly, I haven't crunched the numbers, but I'd bet he's right about that rate of appreciation: the values of 1970s superbikes have been steadily climbing for years now, and with plenty of folks who owned these when they were new looking to relive a lost youth, I don't see that changing anytime soon. Plus, if you do need to sell the significant other on your intended purchase, keep in mind that long, flat 1970s seat should make it a viable date-night ride, compared to a more modern sportbike!

Icon: 1978 Kawasaki Z1R

In the American idiom, there is no substitution for cubic inches. Kawasaki understood the unmistakable allure of power and created what many regard as the iconic hot rod of the 1970s. And as hard as it may be to see, today's mega-hyper-super bikes can trace their lineage back to the Z1R. The recipe remains the same, even as ingredients evolve over time: start with (at least) two big scoops of power, spice it up with a stout chassis, mix in good suspension and brakes, and drizzle with a healthy dose of sporty touches such as rear-set pegs, short bars and aero bodywork bits. Today the power, chassis, suspension, brakes and aero are far superior to those of 40 years ago - but there is little that is truly new.

1978 Kawasaki Z1R for sale on eBay

The 1977-1978 model Z1R was the last of the era before new hardware released in the 1980s. As such, these are the most evolved of the line, and represent the best of this fantastic model. The engine remained the stalwart inline four, air-cooled of course, and breathed through carbs and 2-valve heads. The stock exhaust was a 4-into-1 design, which bordered on hooliganism. Electric push-button starting was the new order of the day, but early Z1s included a vestige of the past in the form of a removable kick start pedal located under the seat (yes, we really have come that far). On the chassis side, the Z1R included additional bracing around the steering head, and introduced triple disks that were drilled for performance and lighter weight. The finishing touch was the bikini fairing, hinting at a key design element for the next decade.

From the seller:
Here is a 1978 Z1R time capsule, I purchased from the original owner at 68yrs old. He purchased new when he was a young man. He rode the bike the bike less than a year. then parked it in his new house that he built. Drained the gas from it at sat until 2015 this was his pride and joy , I purchased the bike from him in 2015 , and brought it back to life. I recently put a new tire on the ,rear new oring chain and rebuilt carbs and syn them. also added kereker header for the 70s look. also have original header perfect shape, original BILL OF SALES! kind of yard to read writing but it there. Dont miss out on this 1 of a kind time capsule.

Long considered one of the first factory cafe racers, the Z1R was a 90 HP rocket that could turn and stop (nearly) as well as it could go fast. This was a sport bike that pushed the boundaries of power and performance; real men rode a Z1R. Today these are 40 year old geezers - there is simply no comparison to anything of the modern vintage. But there is an unmistakable draw, be it the striking stance, the visceral power of the huge four banger, or simply nostalgia. Clean Z1s are climbing in value, although as these were mass produced with no limits they do not benefit from the "Limited Edition" syndrome. However time takes care of that for us, making a great bike stand out today.

This 1978 Kawasaki Z1R looks fantastic; it has some modification (such as the period-correct Kerker pipe), but the auction includes the pricey stock exhaust. If you are a rider of a certain age, this one has to be tugging at your inner child. Even if you were not around or aware of motorcycles during this period of time, this Z1R should stand out. This was the original superbike, and holds its head proudly today. The internet seems to agree, as bidding has been strong on this bike. The auction is up to $11,600 at time of this writing, with reserve still in place. You don't get many opportunities to bid on a bike of this caliber - I recommend you check it out before it is gone. This is more than history; this is a collector model in collector condition. Good Luck!!

Sweet Ride, Man: 1978 Kawasaki Z1R-TC for Sale

Here's one I'd normally post up over at our sister site classicsportbikesforsale.com, but it's rare and it's a sportbike, so I thought this crowd could use a formal introduction to the Kawasaki Z1R-TC. If you’re one of those folks who equate “sportbikes” with “handling”, you may not be familiar with this hulking brute of a machine with a hand grenade for an engine and power to severely overwhelm the limited frame and suspension technology of the day. What's more exciting than that? I mean, Russian Roulette counts as a sport, right?

In the car world of the 1980’s, turbos seemed like the perfect way to increase power and performance in a world suddenly obsessed with efficiency and air quality, and they were getting slapped onto just about everything, so it was only a matter of time before the obsession with boost spilled over into the two-wheeled scene, and Kawasaki was way ahead of the curve on this particular trend.

1978 Kawasaki Z1R TC L Side

The TC was conceived as a quick way to move some lame-duck stock out of showrooms and give Kawasaki a performance feather in their cap. Collaborating with the Turbo Cycle Company, Kawasaki simply converted complete bikes with a bolt-on kit running 8-10psi of boost. Upgraded internals were available for purchase separately but were generally not installed.

In what would be an almost comical nightmare of liability today, buyers simply signed off on powertrain warranty waivers before whooshing off into the nearest wall, or blew themselves up when they ignored the sticker clearly warning them not to tamper with the wastegate to increase boost. Now who'd wanna do something like that?

1978 Kawasaki Z1R TC L Side Low

And even if you didn’t detonate your engine or wheelie into a tree, the very crude turbocharging technology led to wild, on/off boost delivery and made riding this a bit more terrifying than exciting: bendy 1970’s frame and suspension technology combined with an engine that was already plenty powerful before you stuck a honking big turbo on it to give you the worst of both worlds, and a challenge fit for the manliest of motorcyclists…

This particular machine is technically not one of the original bikes and is, according to the seller, a "tribute" built up from a regular Z1R. But honestly this probably feels pretty authentic, since the original bikes were mostly cobbled-together from completed stock bikes.

I really do wish these people would roll their bikes out of the garage to take some of these pictures, though. It will probably help if you imagine Matthew McConaughey reading this out loud as his character from Dazed and Confused.

From the original eBay listing: 1978 Kawasaki Z1R-TC for Sale

Truly awesome looking Z1R turbo with custom Molly graphics and recently painted black bodywork updates,powdercoated frame, many chrome parts on engine,kickstand,etc...very nice Z1R mag wheels,1 of a kind custom seat,early ATP turbo kit with log header pipe + "F" flow high volume compressor complimenting the 1200cc big bore motor  This is not a bike for the timid or in-experienced pilot....even with only 8-10 lbs. boost ,its very VERY fast!(of course you can ride it all day long without getting on boost,its all in your right wrist you know) This is a one of a kind bike with many tasteful updates + cool improvements...tires are in great shape..bike is very stable at high speed with  front steering dampner,fork brace and fully adjustable Marzocchi rear shocks keeping things under control...

Look, let's be clear here: I'm sure those rear shocks are an improvement, but there's no way they actually tamed this beast. You think you're all slick, using trail-braking out there, or using a bit of rear brake to settle the suspension? Try this for some fancy footwork: the power delivery for the TC was so laggy that fast passing on the road called for you to hold the throttle open to keep boost up, while dragging the brakes to keep the speed under control, waiting for an opening in traffic. Sort of like a rolling drag-strip launch...

1978 Kawasaki Z1R TC R Side Front

An exciting, hugely flawed stopgap before the much more modern GPz that followed, the Z1R-TC and the other turbo bikes of the era were an interesting footnote in motorcycling history. While not necessarily all that fast on a winding road, these are massively entertaining on the boost and could be a fun, point-and-hang-on-for-dear-life machine for scaring unsuspecting riders of modern bikes.

Ultimately, the turbo craze was a dead-end for motorcycles: they significantly increased complexity with no real upside: their power delivery was not really suitable bikes of the period and, in most cases, a simple displacement boost proved to be a more effective, reliable way of increasing performance. But whatever, man. Maybe people were just too square to get it.

Memorial Day Special: 1979 Kawasaki Z1R TC2

Z1RTC_22

Perfect for the long weekend coming up, this 1979 Kawasaki represents the first true factory Turbo - and will long be remembered as a fantastic factory hot rod. Sure, the colors and paintwork are straight out of the 1970s, but the performance continues to be contemporary even today. This particular bike has been restored to what appears to be a very high standard, and is an exceptional example of this rare breed.

Z1RTC_15

Outsourced by Kawasaki but sold through the Kawasaki dealer network, the Z1R Turbo is a bit of a legend. Power for the day was astounding - and reportedly much more than the frame, brakes or tires from the time could truly manage. As a result the bike gained a bit of a bad boy reputation. In certain angles it still looks mean and menacing, and on boost can still deliver the goods.

Z1RTC_17

From the seller:
Up for auction is this legendary 1979 Kawasaki Z1R TC2 turbo bike. This bike has been meticulously restored to an award winning condition. This is a really special bike that has taken years to put together!
3500 miles
1000cc
44mm Rajay turbo
New tires with maybe 200 miles on them (Bridgestone Spitfire 11)
Updated Dyna ignition, coils, rev limiter
Rechromed exhaust, turbo, and other misc. items.
New chain, sprocket, brakes, brake lines, shocks.
Wheels polished and repainted
Dyno tested with 145hp to the rear wheel.

All original parts replaced will be included. This includes the directional lights which are not on in the photos.

Z1RTC_10

More from the seller:
One striking feature of this bike is the original factory paint and original Molly Design neon graphics on the body panels! It is important to note that the restoration work on this bike was done by a true motorcycle and automobile enthusiast, and this build has taken many years to complete. I have worked 9-5 at a professional restoration shop for over a decade and have over 30 years experience building cars and bikes. I'll be happy to discuss all the details of the build and share lots of stories to whomever wins this auction!!

The seat is original and in absolutely mint condition!!

This bike won 1st place modern classic at the 2012 Indianapolis Motor Speedway Cycle World Rolling Concourse Show, and also 1st place at the Milwaukee Rockerbox Motorcyle Show.

As an added auction item the Motor Speedway plaque will be handed off to the winner of this auction.

Z1RTC_1

Factory Z1R Turbos are rare machines. The paintwork indicates this is one of the earlier models, and despite the rest of the restoration this original paint has been preserved. These bikes are not cheap in today's dollars, but then again they were not cheap in 1979 dollars either. Interest has been high on this bike, and bidding currently sits at $14,500 with no reserve in place. Click the link to jump over to the auction and check out all of the pictures and details. This may not be quite as iconic as a homologated superbike, but from a historic perspective this is no less relevant. Good Luck!

First of the Turbo Bikes: 1978 Kawasaki Z1R-TC

For Sale: 1978 Kawasaki kz1000 Z1R-TC Turbo Charged Z1-R

When it comes to "factory" Turbo bikes, the Kawasaki Z1R-TC was the bike that paved the way. Created through an arrangment between Kawasaki and Turbo Cycle Corporation (which was founded by ex-Kawasaki Marketing Director, Alan Masek), brand new Z1Rs were sent to TCC, who then modified them with a RayJay turbo and badging. These modified bikes were then sold through select Kawasaki dealers - without a warranty.

From the seller:
This listing is for Kawasaki's 1978 Turbo Charged Z1R: frame # KZT00D0076xx and engine # KZT00DE0076xx. This example is an unrestored, early release unit (1 of 250) with matching numbers and low miles. Upgrades and alterations include:

New Paint (2008)
Allen Head SS Fastener kit (2007)
Oil Return re-routed to Kick Start cover (from Oil Filler cap)
New Tires (2008)
New Sealed Battery (2008)
Welded Crank (2005)
High Capacity Oil Pan w/ Trap Door (2005 & 2007)
Backcut Transmission (2005)
Lock Up Clutch (2005)
New DOHC points cover in 2008 (Moriwaki cover was removed & unavailable)
1075 Turbo Piston kit (2005)
Dynatek Dana S ignition in 2008 (replaced original Martex system)
"TC" Side Cover emblems (2008)

The oil/ filter was changed and tank drained in the fall of 2008, and it has been in storage. The manual, supplement, black zip case, extra key and the other items pictured are included along with any pertinent documentation.

This particular bike is in great condition for such a rare model. The color is correct for a US bike, as is the year (they were only offered '78-'80, although rumor has it that the '79 bikes were simply repainted unsold units from '78). There were only approximately 500 units total of the Z1R-TC created, and even fewer in the stock Kawasaki color. Later models (and Canadian bikes) had the multi-stripe graphic as seen below.

Bidding has been brisk on this example, with the current pricing in the $8k range and the reserve still in place. Look for this one to go up quite a bit more before it ends. Sure, parts may be a bit difficult to find (at least the non-Kawasaki gear), but by all standards this is one fast bike. Straight-line performance eclipsed that of most of the later factory Turbo bikes, with 1/4-mile times in the 10 second range.

This is a real piece of history that deserves a good home. For more info, to simply watch the auction, or to bid on the bike to make it your own, click the link to .
