Fly(er) Weight – 2006 Aprilia RS125

Regularly seen in racing livery and worn around the edges from track use, here is a mint example in factory paint with just 637 miles.  Built to accompany the RSV1000R to the showroom, the RS125 is a lightweight but surprisingly accommodating to an adult rider.

2006 Aprilia RS125 for sale on eBay

The RS125 was heavily revised in 2006 and styled in admiration of its big brother.  The twin-spar alloy frame is lightly polished and coated to stay nice, as is the banana swingarm.  The 28 hp Rotax-based single is very advanced, liquid cooled with a counter-balance shaft and Nikasil coated aluminum cylinder.  Seventeen-inch wheels and upside-down forks aspire to a larger machine.  Brakes are big 4-piston Brembo but singular of course.  Wind-cheating bodywork is occupied by the angular corporate lion.

A SoCal native, this RS hasn't much history, apparently quite stock and without damage.  From the eBay auction:

2006 Aprilia RS125 two stroke bike has a clear California title. Registration is valid till October of 2018. This bike is factory stock except for Arrow full exhaust system that make it sound unique. Bike is in great condition with very low mileage.

A bit of Dr. Jekyll as a starter bike in progressive licensing countries, and Mr. Hyde when a gateway racing motorcycle, the RS125 can take you there.  Pricing by cc was outlandish when new, and a decade later the ask is more than a lot of new singles.  But then this is undeniably sporty, one of the last road going two-strokes ever, built using Aprilia's long knowledge of the lightweight classes.

Grubby but Great: 1992 Yamaha TZR250

From our buddies at Deftone Cycles comes this 1992 Yamaha TZR250 Racing Sport, the dry clutch version of Yamaha's entry into the early '90s quarter-liter two stroke wars. This TZR presents a unique conundrum, as it reportedly runs like a top, but has cosmetically had it. Do you restore it? It certainly is rare enough to warrant the work. Do you ride it? That route would definitely provide the most instant gratification.

1992 Yamaha TZR250 for sale on eBay

If you do decide to ride it, you'll be on a sweet-handling variant of the two-stroke sportbike class, but power could leave you wanting. TZRs were restricted to 44 horsepower in the home market, and it apparently can take some doing to bring them to full chat. That said, Cycleworld recently gave the TZR high praise for its power delivery.

From the eBay listing:

Yamaha TZR250RS 3XV Racing Sport. Dry Clutch Model. NO RESERVE 9,734 Miles (15,666 Kilometers) Completely original and unrestored. Mechanically Sorted. Cosmetically Challenged. All fluids are fresh. Shifts and revs to redline perfectly. Starts effortlessly every time. Very Honest Bike. Things to note: This vehicle is for one who wants a restoration project or just wants to ride without a care. Please see Images. Fuel tank is Rust Free. Factory red wheels are showing their age. Both lower fairings have broken by the lower V and have touchup paint. Bike has Vin Matching State of Ohio Title. 3XV0886** “Buyer is responsible for their own State Requirements.” Imported into the States through all legal channels. Sold as is. Buyer responsible for shipping. Thanks for looking. Please email any questions.

Broken fairings notwithstanding, this TZR is firmly in new supersport price territory, par for the course for two-stroke imports. For the right buyer this will make a great summertime mount.

Well Presented: 1985 Yamaha RZ500

[1.30.2018 - The eBay listing on this nicely-described RZ500 was pulled before we could post. The bike does not appear to be available, but enjoy the right way to present a bike. MI]

Every once in a while RSBFS staff come across a bike that is both rare AND honestly represented. The latter is often as rare as the machine itself. And speaking of machines, today's offering is no less than the vaunted Yamaha RZ500, a twin-crank V-4 two stroke patterned after the big GP bikes of the day. With a GP-inspired 16" front wheel, full bodywork, and exhausts poking out of the tail section shotgun style, the RZ500 has long been a lusted after model by collectors and riders alike. And this particular bike is so nicely documented by the seller that I will let them take over the narrative at this point. Read (and drool) on!

From the seller:
This is my 1985 Yamaha RZ500 for sale. This is a Canadian Version. This is one of the legendary models that Yamaha built for the street use and if you are already looking at this posting, you may be knowing how valuable these bikes are. The bike is absolute fun to ride, not restored, not molested.

It was imported to USA back in 1986 by the previous/ first owner and he had the bike all these years taken well care of. I bought the bike 2 years back thinking that I will keep it forever as a collection.

Now that I have bought a new house and moving in, I have a lot of financial priorities to take care of and I find no other way than letting this bike go. I myself is a picky person when it comes to things I buy and this bike is really worth it. The joy of riding a 2 stroke in power band is something that you won’t get in any of the new generation bikes as per what I think. The RZ500 is one of its kind that really needs to be known.

More from the seller:
When I bought the bike it was all original untouched in any way. I decided to do a complete engine rebuild as the bike itself was 30 years old and I thought it’s a fair thing to do to make the bike completely reliable to ride myself.

A complete engine rebuild was done by the famous 2 stroke specialist Rick Lance (very well known for Lance Gamma) in October 2016, little over a year ago. No expenses were spared. All the engine seals and gaskets were replaced. New first oversize pistons were installed. All genuine Yamaha parts were used for the rebuild. Anything and Everything related to the engine was taken care of. The water pump, oil pump, YPVS etc. work perfect as they should. It is using stock carburetors and exhausts. I did the break-in run and was carefully done. The bike has run only 580 Kms after the engine rebuild. All fluids were replaced at the time of engine rebuild. However I replaced the engine fluids again and topped up the 2t oil two weeks back because I did the break-in run and thought it would be nice to.

The bike starts usually in one or two kicks and settles to a nice idle and runs real smooth through all the gears.

More from the seller:
A new fuel petcock was installed, and as per Rick’s recommendation, a supplement fuel tap is also installed which is really required for these bikes for shutting off fuel completely from flowing to the system when the bike is not in use, and this is the only additional fitting on the bike other than the stock setup and as per me I really like the supplement petcock as it is very useful and really convenient.

New battery was installed at the time of the engine rebuild and is still almost as new.

Rear brake calipers were completely removed and serviced. However, I would like to change the brake pads for more efficient braking. Just did not get the time to do it, now the new owner could 🙂 (A set of brand new EBC brake pads along with the set of caliper pistons and kit goes with the bike. See the list of items I am giving away with the bike for more details).

The Tires are not new but they are in good condition Metzeler tires. However it’s up to the new owner whether he/she decides to put on a new pair before doing any serious fast riding.

All the electrics work on the bike as they should, the Turn Signals, headlight, rear/brake light, meter lights, horn etc.

Everything on the bike is original. The bike is really clean and well maintained. The pictures speaks for themselves.

More from the seller:
Please read below for the drawbacks and negatives as I think it is and important to mention.

1) The body kit is replaced and is a brand new Australian made high quality kit and price runs over $1000. The body kit was replaced because the bike fell down on the drive way (while parked on kick stand) when I was moving things to my new house. It broke the right side lower cowling screw attachment at 2 points.

2) The right side exhaust also got a scratch mark when it fell which I thought of leaving it alone. (Please see the picture)

I bought a separate super clean gas tank from a seller and got it repainted by a high end professional. High quality DuPont paint was used for the paint job and the color matches perfectly with the new body kit. As said please refer to the pictures and you can see the quality.

This is a 32 Year old bike and will have its own minor blemishes and drawbacks as you could imagine. Please don’t expect a 100% perfect showroom condition bike. There is no warranty or guarantee expressed or implied.

More from the seller:
The bike is currently located in Houston, Texas. It has a clear Texas title in my name.

The reserve price I have kept is very nominal and reasonable as per the market price. I have no intentions to make any profit out of selling it, and I am not a business man.

I hope it finds an owner who is just enthusiastic and a bike lover just like me.

How's that for some detail? Gotta love the attention this seller has put into the advert - and based on the photos one can only assume the same treatment was bestowed on the bike. Sure, it has some use and the pipe rash and replacement plastics are a ding to sanitary originality. The rebuild from a reputable shop is a check in the plus column. The big RZ is the most common of the 500cc smoking set here in the US, but that does not make it cheap by any means. Bidding has started out very slow on this one, and the auction sits at just over $10k with reserve in place. I would expect a bike like this to fetch in the neighborhood of $15k, so there is time and room to move if you are so inclined. Check out all of the details here and enjoy a collectable classic that is begging to be adopted and ridden like its repli-racer looks might suggest. Good luck!!

Say it Ain’t So – 1988 Kawasaki KR-1 / KR250B

Dan would have to weigh in on how many bikes Gary has listed and sold on RSBFS, but suffice it to say the past year has been a great success.  Saving the best for last would be a debatable and bittersweet claim, maybe there's another container of gray-market wonders back there ?  Better to relish the KR-1 presented here.

1988 Kawasaki KR-1 KR250 for sale on eBay

Not actually derived from or intended to be a race bike, the KR-1 had a meteoric rise and quick retirement just a few years later.  The parallel twin pushed 55 hp, but peaky like no one's business, making power just between 6,000 and 11,000 RPM.  Never offered stateside, it thrilled young riders in the U.K. and the Pacific rim, and has only occasionally found its way here.  The super-light under 300 lbs. machine was over-equipped with dual disks, adjustable suspension, and 17-inch front / 18-inch rear wheels.

Gary has made presentation of gray market specials look easy, but this one is different.  Rather than doll up someone else's issues, this KR-1 was brought over restored, low miles, just about perfect.  As always, it's ready to run with legal title and registration.  His comments from the eBay auction:

Up for sale is a 1988 Kawasaki KR-1 with only 20,640 kilometers (12,825 miles). Bike is in mint condition. The collector whom I purchased it from in Japan did a full frame up restoration. Complete engine, front forks, front and rear brakes, drive train, rear suspension, custom paint restoration. I don’t normally buy bikes like this but when I saw that no expense was spared to make this bike look and run new, I just had to have it. Bike looks gorgeous and is in mint condition. There are only a few very light scratches and handling marks. All fairings and components are 100% Genuine OEM Kawasaki factory. All replacement parts used in the restoration were genuine OEM parts. Bike is completely stock. Bike runs like new. Comes with new battery and new engine fluids.

I’ve saved the best for last. The last is here.

Kawasaki saw the writing on the wall early and focused on four-strokes for 1993.  But the power delivery, quick steering, and riding position of the KR-1 are legend.  Hopefully an adult rider can keep it out of the tank slappers it destined novice riders to experience.  In a era where a successful design could be considered 100 machines ( Buell or Bimota ), or a thousand ( Ducati or Moto Guzzi ), Kawasaki saw the future on the other side of 10,000 KR-1's.  But for a fan of the green and white, there was never such a lightweight.

Cali-Titled Two-Stroke: 1990 Kawasaki KR-1S for Sale

During the 1980s and early 1990s, the vibrant quarter-liter two-stroke class saw the NSR, RGV, and TZR go at it with knife-fight-in-a-phone-booth intensity. Notably missing from much of the action was Kawasaki. It didn't help that Kawasaki didn't start building a two-stroke sportbike until 1988 and abandoned the class in 1992, before the other Japanese manufacturers and, as a result, the Kawasaki KR-1S is a bit of a holy grail for two-stroke fans in the USA. They're really nearly impossible to find in any market, as Kawasaki produced less than 10,000 examples in total, and they were obviously never sold here in the US.

If all you've done is glance at the spec sheets of the class competitors, you could be forgiven for thinking the bikes in this class were pretty much the same, with two-cylinder, liquid-cooled two-strokes, aluminum beam frames, six-speed gearboxes, and a suspiciously identical 45hp output. In fact, sometimes only a catchy acronym for the power valve gives the manufacturer away, although KIPS, ATAC, SAPC, and YPVS all performed basically the same basic function. But period road tests and two-stroke enthusiasts claim that each has a distinct character that seems line with corporate sterotypes: Honda's NSR was sophisticated and refined, while Suzuki's RGV was a bit of an unruly wild-child, fast and a bit fragile. But although Kawasaki joined the party late and left early, they left an indelible impression and their KR-1S was claimed to be the fastest, the easiest to tune, and have the hairiest handling of the bunch.

The KR-1S was powered by a liquid-cooled 249cc parallel-twin with a 180° crankshaft that also drove a balance shaft to improve smoothness, and put power to the back wheel through a six-speed gearbox. The "S" model seen here featured wider wheels at the front and rear, and tested top speed of 139mph. An "R" model was also available, but is nearly impossible to find, with fewer than 200 built. Interestingly enough, last month's Practical Sportbikes features an article that discusses the rebuild of a KR-1R in detail.

Like yesterday's ZX-7R, this KR-1S is slathered in green, white, and blue graphics that suit the bike's brash personality. Happily, the seller also includes images of the bike with the fairing removed, as it shows off the very slick aftermarket expansion chambers and another odd detail: the engine sits almost entirely below the frame! That of course keeps the bike relatively narrow, but seems strange that most of the engine is suspended beneath the frame, rather than nestled between the frame spars.

From the original eBay listing: 1990 Kawasaki KR-1S for Sale

1990 Kawasaki KR1S C2. I am relisting and selling another bike out of my prize collection. Journalist called the KR1-S the most exotic and fastest of all the 250 2 stokes of that era. This KR1S is a UK model. Which means UK CDI power box, mile per hour speedo. Non-restrictive. Always been in street bike form. Not a converted back race bike. This is truly a rare bike. Unlike NSR’s, TZR’s and RGV’s and even Aprilia RS’s that come up for sale now and then, you very rarely see one of these for sale. I have owned this bike for over 10 years. I have spent many of thousands of dollars on upgrades. I mean many! I installed a pricy set of Dyna mags magnesium rims. The old KR1S aluminum rims came with a 17” front and an 18” rear. These are 17” front and back. Light weight magnesium and make sporty tires more available. I have put on a set of Michelin pilot sport tires. Green D.I.D.  O-Ring chain with gold aluminum sprocket. Beautiful high end custom steering damper. Then I had made a JMC fully braced swingarm with eccentric adjustment. Beautifully polished. I was told at the time that this was the only top braced swingarm that JMC has ever made for the KR1S. I installed a huge custom made “Pace” radiator made for the KR1S. This radiator is huge, and solves the problem of any overheating. If anything I have to tape of part of the radiator when its cool out. But a nice position to be in. Silicone radiator hose are used. Then I purchased a nice new set of Jolly Moto pipes with Carbon silencers. Bikes sound great and pulls better. I had the rear shock rebuilt and the shock spring powder coated green to match the bike. Front forks have been recently rebuilt with all new bushings, oil and seals. Rebuilt both the front and rear calibers with new stainless pistons, bolts, and seals. I had them powder coated too. Custom made steel braided brakes lines with aluminum fittings. They look like new. I also installed new light weight disks front and back.  Have a fortune in light weight titanium, stainless, and aluminum bolts throughout.  All the lights and switches work. The bike has 16,600 miles on it. So a far as I know the motor has never been touched.  I had plans to rebuild the motor and including all the parts to do it.  I have everything needed to build it included. But now I have gotten old and don’t have time for this project. I have tuned it up, changed all the fluids. Adjusted the power valves, etc. Bike does still run strong but mileage is getting up there for 28 year 2 stroke. The original bodywork on the bike is not too bad for its age but not perfect either. I had a few tabs and small cracks repaired. The tank has a couple tiny little chips, but is in remarkably in good shape for its age. No dents. The tank is clean inside without rust. The body panels have a few scratches and touched up spots.  Still not all that bad for its age either. Please refer to the pictures for more details. I am including the stock rims with a brand new fresh powder coat on them. The stock pipes, radiator, manuals, and various other parts as seen in my list and pictures. Lots of stuff.

The following is a list of some of the parts that are included with the bike, but not complete. No much to list. Please refer to pictures.

  • 4 brand new piston sets, including, rings, pins, clips, and small ends
  • Complete set of crank seals and crank bearings, plus new rod sets. Everything needed to completely rebuild the crank like new.
  • 3 gaskets set, plus one extra head gasket
  • New Water pump part set
  • New carb sets including floats
  • Power valve seals
  • New billet aluminum power valves and power valve wheels
  • 1 extra new front disk
  • Numerous new seals and bearing that go into the motor
  • Stock pipes in good condition
  • Stock swingarm with fresh paint and new bearings and seals. Like new
  • Stock radiator in excellent condition
  • Stock wheels with fresh powder coating, sprocket,  and cush drive

All the old wheel bearing, wheel spacers, front and back disks, sprockets, brake lines, and caliber parts. The old original nuts and bolts that were replaced with titanium and stainless, aluminum

Bike comes with a current California registration and title!  Has all the correct serial and engine numbers, but is listed as a 1980 instead of a 1990. You might think that wow I am asking way too much for this bike? I say “find don’t buy it then”. What I can say how often you see one of these for sale in this condition, with all these extras and titled too? Try to find another? These bikes are only going to increase in value as time passes. Plus I am including thousands of dollars in extra parts.

So the $17,500 asking price is big money for a two-stroke sportbike, but I'm betting it will find a buyer: if that California title is valid, I know a couple folks who'd love to snap it up, and it's really not all that far off what folks have been asking for pristine NSR250s recently. It isn't completely stock, but all of the upgrades described by the seller are clearly intended to thoughtfully boost performance and handling. All-in-all, it's one of the coolest bikes we've posted recently.

Pristine stroker: 1996 Suzuki RGV250SP VJ23A

This 1996 Suzuki RGV250SP appears to be in the hands of our friend Gary in Utah, and like the lion's share of his bikes, it's nigh on perfect. The original fairings and tank show very few flaws, and from a glance the biggest blemish seems to be on the aluminum boot guard.

1996 Suzuki RGV250SP for sale on eBay

Based on frame number, this appears to be a T model VJ23A, which in stock form for the Japanese market was limited to just 40 horsepower. That should still be a laugh riot in a bike this small and light, but the 70-degree v-twin is well known for being capable of around 60 horses if you massage it right.

The VJ23s represent the latest and greatest in Japanese two-stroke technology. While they share v-twin architecture with the VJ21 and VJ22s machines that came before, the motor in the later machines shares almost nothing with its elders, from revised powervalves to a narrower vee angle.

From the eBay listing:

Up for sale is a 1996 Suzuki RGV250SP VJ23A with only 32,741 kilometers (20,344 miles). Bike is in mint condition with only a few scratches on the left side upper, a few light handling marks and some rub marks on the heel guards. No dents in the tank, no cracks in the fairings, and has a very clear windscreen. Bike is completely stock and all fairings and components are 100% genuine Suzuki factory OEM. This bike is gorgeous! The previous owner took extremely good care of it. Lol, this bike was loved as a child. Comes with new battery, new fluids and new fork seals. Runs like the day it was new. This is a premium bike and very rare to find in this condition. Bike comes with a Utah state title and is titled as a streetbike for road use. Text 801-358-6537 for more pictures and questions. Auction could end anytime as bike is for sale locally. $200 deposit due immeadiatly after auctions end thru PayPal. Balance due within 5 business days by check, bank wire or cash in person.

The bike has certainly been ridden, which makes its condition that much more impressive, and it comes with a clean Utah street title, so it should be good for another few years of high-strung fun.
