Red, white and smoky: 1985 Kawasaki KR250S

The 1985 Kawasaki KR250S was a street-going version of a two-stroke road racer that took home four championships in the 1970s. They weighed less than 300 pounds, made 45 horsepower and packaging was kept tight with a weird “tandem twin” engine design. The mill was essentially two singles in a line with a unified crank. Before the KR-1, this bike carried the two-stroke banner for Kawasaki.

This 1985 Kawasaki KR250S is in excellent shape and was just imported to the U.S. from Japan. It wears the marks and blemishes of its years and has not been treated to U.S. paperwork. In California, you won’t have any luck with documentation, but it might be worth trying in other states. Even so, as a vintage ride, limited trackday mount or museum piece, there is real value to the collectors among you.

From the eBay listing:

1985 Kawasaki KR250S located at our shop in Santa Ana, California. The pictures in this auction were taken at our shop in Japan. This bike is in excellent condition for it’s age.

Featured Listing: Zero-mile 1997 Bimota VDue time capsule

CMG Motorcycles has two motorcycles on RSBFS right now, a 0 mile VDue and a brand new Bimota Tesi! Check them both out! -dc

There is no more tantalizing bike on the planet for me than the Bimota VDue. A bespoke Italian chassis from the finest boutique bike maker on the planet, draped with exotic suspension and prodigious brakes with fuel injection, the waistline of a ballerina and 110 or so two-stroke horsepower. A dream machine for the ages, it was supposed to kick Bimota into a new market segment in a cloud of sweet-smelling blue smoke. Instead, the dream went up like a Persian Gulf oil field and took the iconic nameplate down with it. 

Bad power delivery, seizing pistons, oil leaks plagued the first couple hundred VDues, and most owners returned them. Fixing the issues, which meant sticking carburetors on and invalidating the bikes for street use, ruined Bimota’s finances. Eventually, an engineer on the team that put the idea together bought the leftovers and fixed them. He sold about 120 that put out more than 120 street-legal two-stroke ponies, but by that point the toothpaste was out of the tube. 

This 1997 Bimota VDue never experienced any of those issues, because it has racked up exactly zero miles in its 22-year life. It is a literal museum piece in absolutely flawless cosmetic condition. Given the likelihood that its mechanicals are absolutely useless, both by design and from sitting, this thing is perfect for a collector who needs the finishing touch on a prestigious collection. 

Having never moved under its own power, it wears its original tires, which are now shiny from sitting around vulcanizing for a couple decades. But that’s no matter. When else will you get the chance to own a bike that is original and untouched down to the protective film on the windscreen? The thing we love most is that this bike is in its best state: an unblemished embodiment of bold vision and faith in engineering. It deserves to stay that way.

It is available in Christchurch, New Zealand for $48,990 USD and requests and inquiries can be sent to Brad by email  – here –.

Featured Listing: 2000 Derbi GPR50R

Update 8.4.2019: Price lowered to $2999. Good luck to buyers and seller! -dc

Comments are optional on Featured Listings and enabled on this post so you can chat with the seller. -dc

Talk about punching out of your weight class. The 2000 Derbi GPR50R made its “49cc” brethren look even wheezier than usual when it hit these shores as a storm of silky handling hornets. Popular with new riders in Europe, the GPR50R is one of just a couple of examples of nearly full-size two-stroke 50cc bikes that made it here. 

Titled as scooters though they may be, the little Derbis cheated with a 75cc engine that was good for an astonishing 9.5 horsepower. That’s enough to get a sub-200-pound adult to close to 75 mph with a decent draft. They need to rev to the moon to get out of their own way, but once moving, the bikes do their best Grand Prix impersonation, with suspension and chassis characteristics of much bigger machines. 

As with any Napoleon complex street brawler, momentum — and clutch fanning — is the name of the game. 

This 2000 Derbi GPR50R has been kept quite beautifully, and does a fantastic job aping the legendary Ducati 916. A heady boast for such a reedy little machine, but the quality and pedigree are there to back it up. It has been treated to a Leo Vince exhaust, bigger carburetor, carbon fiber reeds and the afore mentioned factory displacement bump. The decals and livery are custom, and look great. The suspension has been reconfigured to accommodate a 200-ish pound rider, which should make day-to-day use a damn sight easier and more comfortable. 

From the seller: 

2000 Derbi GPR50R in Chicago

These were rare but official US imports and are titled as 49cc (scooters in most states) like the foreign versions.  However, US spec bikes came straight from the factory with the larger EBE075 motors and do 70+mph. This bike has 6,157 km (3,842 miles) and many upgrades;

Motor modifications

Airsal cylinder/piston kit (I have the original cylinder and piston in good condition)

Leo Vince exhaust w/titanium can

24mm Mikuni Carb w/throttle and cable

K&N air filter

Carbon fiber reeds

Carbon fiber oil pump block off plate

Cosmetic modifications

Red/white Ducati 916 SPS replica paintwork

Custom Cagiva-era 916 style decals

Rider’s seat recovered in black leather

Passenger pad recovered in red/white vinyl

Aluminum fairing fasteners

Additional mods

Doppler rear shock with heavier spring

Forks rebuilt and resprung by Superbike Suspension

Billet aluminum peg bushings

New chain/sprockets

New Avon Viper Stryke tires

The bike is fun to ride and with the suspension upgrades will handle a full size adult.  It is currently optimized for someone in the 200 pound neighborhood. There is a crack in the paint along the seam of the dummy tank (pictured).  There is a small nick in the paint on the right side tail piece, but I’ve got spares of both tail sides…and they’re already painted.

For just $3,500, you’re getting a cool piece of superlightweight history, made even more special by its imitation of much heftier and faster machinery. To get your hands on it, contact Adam at plus790@hotmail.com

Featured Listing: 1976 Yamaha RD400C

If you bought a mid-size two-stroke Yamaha streetbike in 1975, you got the very, very good RD350. You also got shortchanged, because buyers who waited just a year got the 1976 Yamaha RD400C, which Cycle World lauded as the perfect motorcycle, and which carried way more improvements than a simple displacement bump. 

1976 Yamaha RD400 for sale on eBay

The engine had been gone over with a fine-tooth comb, which resulted in the expected power increase, noise reduction and improved refinement at low rpm. Yamaha worked hard to keep the naturally antisocial two stroke as quiet and easy to ride as tech allowed at the time. The result was 35-ish rear wheel horsepower and a top end north of 100 mph, still impressive figures for a 400. 

The chassis got a good going-over, too, with new geometry that aped Yamaha’s all-conquering grand prix bikes of the 1960s and disc brakes front and rear. All that lined up to create the 1970s answer to the RGV250s and CBR400RRs of the late 1980s and early 1990s. The sublime reviews showed Yamaha’s efforts were well spent. 

This 1976 Yamaha RD400C is in fantastic restored shape, with a raft of powdercoated parts, a functioning oil injection pump and functional self-cancelling turn signals. It has been kept original with the obvious exception of modern rubber, so the experience aboard this thing will be damn close to what the guys at Cycle World felt 43 years ago. 

From the seller: 

For sale is a clean RD 400C for sale with a frame up restoration. Bike starts up first or second kick and very reliably. Bike is original to the finest details with original shocks and exhaust. Electronics gone through and checked. Original mileage is approximately 13027 miles. Titled and registered with California clean title in my name. Matching vin and engine numbers.

 Numerous work includes: 

 Motor has been gone through with new seals on the crank 

Powder coated frame 

re-coated nuts and bolts after complete strip down 

Powder coated numerous parts after strip down including swingarm 

New or refurbished parts include rubber parts, seals, gaskets and replacement worn parts 

New Bridgestone Bt45 tires with new bearings front and back 

All electronics work even the self canceling turn signal unit 

Tank is free of dents and has been resealed. 

Front and rear brakes rebuilt with new master cylinders and Caliper seals brakes work flawlessly suspension is supple in working order for original equipment 

new chain 

Oil pump intact with rebuild and adjusted 

Carbs synced and gone through with new rubber tip float needles no leaks here 

This RD was painstakingly gone through to keep to original condition. Although not absolute perfect would be a perfect addition to a collector. Starts and rides brilliantly for age and is great blast from the past with that unforgettable two stroke smell. Too good looking for me to keep and ride this bike is need of a new home with someone who will appreciate its heritage.

Featured Listing: One-owner 1984 Yamaha RZ350

Update 8.5.2019: This bike has SOLD to an RSBFS reader. Congratulations to buyer and seller! -dc

This 1984 Yamaha RZ350 wears the iconic black and yellow Kenny Roberts livery and signatures, is original aside from some airbox mods and jetting and is with its original owner. It has 15,000 miles on it, but has been used very sparing over the last few decades, and it wears only its second front tire. The rear is similar, though somewhat unsurprisingly it has had three rear tires.

Built as emissions were about to kill street two strokes in this country, the RZ350 wasn’t as simple as its earlier counterparts, with powervalves to ease the two-stroke hit and catalytic converters to calm the EPA, but it was still a deadly simple and effective package. With just 331 pounds pushed around by 50-ish horsepower and roadracer handling, there was little not to like about the bumble-bee liveried machines. Sure, there were simpler ways to go fast, but there’s a certain joy to unrefined fast.

I’m going to let the seller do most of the talking, but this bike is a fantastic example of the breed, and is worth every red cent to the right person. He certainly has come to the right place to find the next steward of this wonderful beast.

From the seller:

1984 RZ350, Kenny Roberts Edition. Original owner, 15K miles. 99% original. You won’t find many in this condition. Still has the stock exhaust with catalytic converters. Last registered in 2011. Always stored inside & under cover. Colorado motorcycle so never exposed to moisture & humidity. Have the original sales paperwork, manual and tool kit. I was the service manager at the shop I bought it from. Outside of an 82 YZ490 hold over I bought at the same time, this was the only new motorcycle I ever had. The 490 was just a cheap dirt bike but this was something special.

Only modifications I made was to remove the snorkel from the airbox and drill some holes in the top of the airbox cover, add Boyesen reeds (have the snorkel and stock reeds) and rejet.

It’s on the second front tire (which would need replaced if you’re going to ride it as it has come cracking) and the third rear tire. The second rear tire I put on was a take-off from my road race bike in the late 80’s. Unfortunately it rubbed on the chain guard, so I notched it to clear. In hindsight I wish I hadn’t done that but you can only tell if you look closely at the backside of the guard. Replace the chain guard and top cover of the filter box and it’s 100% original out side of tires, chain and battery.

Original spark plugs and grips. All hoses and rubber are original and in good shape. Paint and plastic are in good condition and still shine. Has some minor scuffs and scratches as would be expected for a rider. Worst is the scratch on the LH side of the fairing and crack at the top of the fairing on same side (from vibration).

To get this in riding condition and ready for selling, the following was done: New battery and chain. Flush out the tank – clean, just a few very minor spots of surface rust near top, Clean carbs: amazingly clean for not being ridden for almost 10 years – only minor varnish in the bottom of one which cleaned up easily. Changed oil and coolant. Clean & oil air filter – which is also original and still in good condition; not falling apart. There was evidence of mice putting some seeds up there but that is all. Changed brake fluid – rear reservoir was very clean. The front one was very dirty and had considerable moisture/crud in it. Sight window is cloudy and shows it age.

Everything works. Runs and rides well – you wouldn’t know this is a 35 year old, non-restored motorcycle. Of course despite it’s great condition, it’s still bought as is.

$8000

The asking price is absolutely in line with the provenance and condition of this machine. We’re not dealing with a Craigslist crapshoot here, and the ask reflects that.

Featured Listing: 1991 Suzuki RGV250 SP2

The 1991 Suzuki RGV250 SP2 was the baddest two stroke sportbike Hamamatsu was kicking out in the early ‘90s, with a dry clutch, wide-ratio box and fully adjustable suspension adding even more agility and precision to the little bike’s already lithe and precise nature. With 60-ish horsepower when uncorked and a shade over 300 pounds to push around, the updates meant the reedy little RGV could seriously hustle. As in, give supersports problems in the twisties hustle.

1991 Suzuki RGV250 SP2 for sale on eBay

Thanks to those crude, dirty little powerplants that make horsepower like the Middle East makes the oil to run them, the bikes didn’t need to be massively complicated to produce prodigious speed. With conveniences like oil injection, the bikes weren’t even that cumbersome to refuel, as long as you checked the oil level at gas stops, you were good to go.

This 1991 Suzuki RGV250 SP2 has been legally imported to the US and treated to a cosmetic restoration and some tasty Tyga go-fast pieces. The bike shows its age on many of the aluminum pieces and the dash, but the wheels and bodywork have been repainted and look excellent.

From the eBay listing:

This may be one of the best looking bikes Suzuki ever made, and this is one of the very rare SP2 versions!!

I bought this bike in Japan about 3 years ago. It was legally imported into the U.S. and it has a clean and clear Arizona street title and plate. In most cases with 11 digit VIN bikes you will not be able to register this in California.

This is a very rare Sport Production II version of the VJ22, the SP2 came with a dry clutch, the wide ratio transmission, fully adjustable suspension front and rear and aluminum lower triple clamp and rotor carriers.

This is a lower mile original bike. I STILL HAVE THE ORIGINAL EXHAUST AND REARSETS if you want to put the bike all the way back to stock!

Very low original miles at around 10k, not raced or abused. This bike had some light scratches and sun fading on the bodywork so I went about the painstaking task of getting all the OEM bodywork repainted in original colors! I have also just powder coated the wheels back to an original gloss white.

The bodywork is all original and the paint is perfect with zero miles since it was restored. The bike has brand new Michelin Street Radials, new valve stems, full service front to back including all new fluids, plugs, coolant, new air filter,brand new Tyga Full Exhaust system, new Tyga rearsets and brand new chain and sprockets!!

Bike starts on 1 to 2 kicks when cold and 1 kick when warm. All electrics work and it has a good battery installed. All wiring is intact and original. Oil injection in place. The bike comes with a complete new carb rebuild and full jetting kit, carbs are currently stock and fine, but this kit will allow you to jet the bike for your location/conditions.

There is some light corrosion that I have not attempted to clean up on various parts of the bike as seen, so it will clean up even better than it looks now. ! Some fading on the passenger seat, and to a lesser degree the rider seat as well, bit no tears.

Have not seen an early RGV VJ22 SP with the banana swingarm this clean in a very long time, and few of these survive in Japan…those that do are not cheap…or not for sale. Don’t sleep on this one….really one of the nicer 250 two strokes from my collection.

PLEASE CHECK OUT MY OTHER LISTINGS FOR MORE BIKES!!!

The auction is live for almost another two weeks, but with a Buy-It-Now option, we doubt an RGV this nice will hang around too long.

Featured Listing: 1991 Suzuki RGV 250M in Canada

There are so many iterations of the Suzuki RGV 250 Gamma running around that you either need to be a savant to keep them all straight, or refresh yourself every time one comes up. There are VJ21s, VJ22s, VJ23s and a bunch of SP variants in between. Some are corked, some are uncorked, which means, depending on the variant, you get anywhere from 40-odd to nearly 70 horsepower. 

What you have here is a 1991 Suzuki RGV250 M, a UK-market screamer that was delivered without any restrictive bits and a full stable of about 65 horsepower in a bike that weighed the best part of nothing. We’re talking Suzuki DRZ400 territory for a focused street/track bike with more than 30 horsepower on the 400 and a set of sticky tires and cutting edge suspension. 

Unfortunately for the United States, there was no need for mass-market, fast 250s, as tiered licensing has never been a thing here, and insurance on a 600 is pretty cheap. So, newly licensed riders could hop on a CBR600 and never have to worry about fouled plugs or fuel mixture. The shame, of course, is that advanced riders who didn’t want the thrust of a supersport or literbike never got their hands on 250 two strokes, which have a habit of showing up higher-horsepower mounts.

This RGV250 has been ridden extremely sparingly since being moved to Canada 15 years ago, and shows little wear and tear. It looks like it could use tires, but comes with a raft of spares, including complete bodywork and a replacement fuel tank. 

From the seller: 

Original 1991 RGV 250 M 

Not a grey import 

Original UK spec model with 65hp, sourced in the UK and imported by myself

Road Legal in Canada, with proper registration

Comes with the following spares, Complete of extra bodywork, extra fuel tank, factory service manual, factory owners manual, top end gasket kit

Full decal kit to make extra body work into Lucky strike replica.

Originally had 5300 miles on it and changed the clocks for kilometer ones to make legal in Canada.

I have owned this bike for the last 15 years or so and only done about 300km on it.

New battery

Runs great 

Truly a collector’s item.

This bike is in ORIGINAL condition and has been in storage since it was last ridden in 2012

Featured Listing: 1988 Yamaha RZ 350 in Canada

Update 7.17.2019: This bike has SOLD! Congratulations to buyer and seller! -dc

This 1988 Yamaha RZ350 is a gorgeous example of one of North America’s last-ever road-going two-stroke sport bikes. As the 1980s waned, environmental regulations had all but ruled the simple-but-effective machines off the roads on this continent, leaving the smoky mounts for European roads.

But what a swansong the RZ350 was. The parallel twin used the variable port height Yamaha Power Valve System that was developed over years in 500cc GP competition, which gave the normally peaky powerplant a respectable torque curve. The bikes still made prodigious power for their displacement and weight, and the two stroke was still a two stroke, which meant the machines were not to be trifled with.

In the United States, the RZ350s are best known without a fairing and with the bumblebee paintjob that adorned Kenny Roberts’ race bikes. This example wears a full fairing, and Yamaha’s equally cool red, white and blue block paint scheme.

From the seller:

1988 Yamaha RZ350 – Canadian bike – amazing survivor condition – never been down! The closest thing you can get to going back in time and buying a new 1988 RZ350 off the showroom floor.

Mileage: 8,223 miles (13,234 kilometers)

History – 2 owner bike prior to me – first owner – owned for 7 years – 2nd owner owned for 23 years – he rode the bike once the day he bought it and and carefully stored it after that (he has a big bike collection)

Factory Tool Kit and Original owners manual included

Service – The bike has been completely gone over by a motorcycle shop very familiar with 2 strokes.

Items addressed in $2K service in November 2018 include:

– new tires
– new battery
– carbs cleaned
– fork seals replaced
– coolant and brake fluid flush
– master cylinder serviced
– kick start oil seal replaced
– steering head bearing replaced
– full safety inspection completed

Imperfections – the tabs where the body work attaches under the seat have cracked – these are not visible from the outside – could be plastic welded back to be complete. There are two hairline stress cracks on the bike (shown in pics) – first is one side of the fairing – second is where one of the mirrors attach to the bike.

Paint condition – excellent – stunning to look at

Reason for selling: I had bought the bike as I had always wanted an RZ350 and was looking for something fun to ride for pleasure use. After buying it and having it serviced, I realized the bike is such a rare survivor that I don’t feel right risking riding it around town. It really should be in the hands of a serious collector or a museum. I have bought another “rider quality” RZ350 for my own personal use.

Factory Tool kit and Factory owners manual included

Price $9500 $8,000 US.

Importing a bike from Canada to the US is not a big issue – filling out the appropriate forms or using a broker is all you need to do. I can assist with shipping but all planning and costs are the buyers responsibility. I know an excellent transport company based in Canada that can deliver to the US and help with all the paperwork.

Bike is located in Toronto Canada – about 1.5 hours from the Buffalo, New York border

Though the bike is in Canada, its age should make it eligible to be imported and registered fairly simply. With a recent service, it’s ready for a long riding season, though if you’re like the seller, it might be hard to stomach the idea of road hazards marring that beautiful paint.
