Rare Zoot -1985 Yamaha RZ500

Mike 3

Originally available in Canada as one of those morsels of forbidden sport fruit taunting US riders from just over the border, this 1985 Yamaha RZ500 now resides in the US of A down Florida way and is looking for a new home. Sporting updated expansion chamber pipes, a steering damper and a few more stickers than your average display queen, this RZ looks to be largely uncut and in good shape for the approximately 18,600 miles shown on the all KM clocks. The big V4 RZ two-stroke is getting more and more rare as the years go by, so finding one to love and to hold can be a daunting task.

From a pricing perspective the big RZ is an ever-appreciating asset. The market has yet to top out on these, and we have seen them hovering just under – as well as over – the $20k mark for some time. This particular example is being offered in a Buy It Now only format, with the price set at $25,150. The seller is open to offers, however, so there may be room to move if you are looking to move one of these smokers into your stable. You can check out all of the details here, and Good Luck!!

Parallel Universe – 1982 Yamaha RD350LC

Mike 3

For a significant number of riders across a wide swath of age ranges, the Yamaha RD series represents the pinnacle of the adolescent hoonabike. Sporting a minimalist profile with sporting intent, the lightweight two stroke twin has been a longstanding favorite – be it the classic air cooled RD, the not-imported-into-the-US liquid cooled RD-LC, or the scant few years of the RZ. Today’s example is a beautiful Canadian RD350LC, imported, titled and ready to rip.

1982 Yamaha RD350LC for sale on eBay

Much of what makes the RD series so much fun is what isn’t there; namely weight. Just 315 pounds dry, the RD gains only a few pounds fully burdened for battle with a little bit of water and a tank of fuel on board. Those sub 330 pounds are pushed along by nearly 50 angry bees worth of ponies, all bolted to a decently stiff mild-steel frame with a single shock rear suspension adjustable for preload. From those basic bits comes a whole lot of fun. This is riding at its most basic; just you keeping the tach above 6k or so, and the RD gobbling up the corners.

From the seller:
1982 Yamaha RD350Lc numbers matching Import from Canada. Clean Florida Title.
29k speedometer is in kilometers
Runs perfect fully dialed in
Repainted tank (BD cycles)
New brakes front and rear
New brake lines
New rear bushes
New tires front and rear Avon / Bridgestone
carbs refurbished with all new jets
New intake mounts
New Dynatek Coil and leads
New seat cover
New clutch springs and bolts
New neutral switch plate
New radiator (additional capacity)
New battery
New fuse box
Powderedcoated side covers exhaust in high heat
calipers fresh rebuild new master cylinder
Complete tune up runs perfect must see very rare
clean florida title in my name

These LC models of the RD series pre-dated the RZ, and 1982 predated the use of the Yamaha Power Valve System (YPVS) which was to come one year later. This bike looks quite nice, although we would love to see more pictures of it. The seller clearly has some two-wheeled taste by the looks of some of the other iron in that garage. This bike has a starting bid of $9500. Given the prices of RZs these days, that might not be too far off the mark for a clean import. Zero bids as of yet, but you can check out all of the details here – including a walk around video. Good Luck!!

Featured Listing – 1988 Suzuki RGV-250 SP with just 6,132 Miles !

Donn 0

Update 3.20.2023: Sold for $12,400! Congratulations to buyer and seller! If you have a Rare SportBike for sale, list it on RSBFS! -dc

Having been in collectors’ hands from early on, RSBFS reader Brian’s RGV250 SP is immaculate and freshly serviced. 1988 was Suzuki’s first year with the V-twin 249cc engine, and the SP sports a close-ratio cassette gearbox.

1988 Suzuki RGV-250 SP for sale on eBay

All new for 1988, the RGV250 was the best built, most expensive and most powerful ( in unrestricted markets ) 1/4 liter machine at the time.  It uses twin 32mm Mikuni carburetors and a single-acting power valve to balance 30 ft.-lbs. torque with the JDM limit of 49 hp.  Twin chassis spars are aluminum alloy with brackets holding the rear set pegs.  Conventional forks and Full Floater monoshock are multi-adjustable, with 17-inch wheels front and rear.  Brakes are outstanding in the segment with dual 290mm floating disks and 4-piston calipers up front.

Looking barely used, Brian has just had his RGV-250 serviced and with new tires.  Factory low-profile signals are slick, along with the racey Sakaguchi chambers.  Brian’s notes from the eBay auction –

I recently imported this RGV250 from Japan in late 2022.  The bike was purchased from a private owner’s collection by JCG Trading (Graham Crump) and brought to the states   It went directly to Downshift LA (Angel Perez) for a carb cleaning, safety check, and new tires.  It is in excellent condition and starts smoothly with one kick.  The bike is 35 years old and has a few small scrapes – shown in photos, but the overall condition of the body is excellent.  The engine is immaculate and runs beautifully. 
All original import paperwork is included with a Bill of Sale, CBP Customs Clearance, Import & Shipping documents, and the Japanese Original Title with all bike details.
Sakaguchi  Dual Exhausts.  There is one small very small dent in the left hand side, likely from a rider’s foot.  JDM models had flush mount lights and the SP model adds a brake reservoir and closed ratio gearbox.  Since import, this RGV250 has been ridden only twice for testing rides, with a total of 9.2 miles on brand-new Bridgestone Battlax BT090-Pro Tires.  
I’m only selling as I am a bit too big for this bike.  The RGV is much lighter at only 282 lbs (dry) and faster through the corners.  The real power kicks in at around 8,000 rpm and it feels like suddenly it has 2x the power.  It’s a true screamer and a very rare, prized bike to add to your collection and is ready to ride. 

RGV-250’s sold out early in Britain, where they were unrestricted and reviewers said they could putt around town under 5,000 rpm, and steal the show when the power valve opened at 8,000.  The street might not be the best place to do all the shifting needed to keep the revs up, or explore the extraordinary lean angles possible, but maybe a remote twisty bit or track day.  Keep an eye on the – eBay auction – and you can reach Brian using the Contact Seller button.



Crazy Cat Lady – 1985 Yamaha RZ350

Mike 3

Keeping the pre-mix party going is today’s very rare, totally stock (right down to the factory catalytic converters) 1985 Yamaha RZ350 in red/white colors. Much has been said regarding these little RZs, and they are generally a much-lusted after bike despite the smaller capacity. This bike has low miles, and looks to be pretty authentic.

1985 Yamaha RZ350 for sale on eBay

From the seller:
Listed for sale is an all original 1985 Yamaha RZ350 with 5,739 miles. Other than a few cosmetic blemishes, it is an all original properly maintained vintage liquid cooled 2-stroke performance survivor. Unlike most RZ350 motorcycles, this has not had any modifications to engine, exhaust, or suspension. It also has the original tires with a new set included (see photos) with the sale. This motorcycle has catalytic converter exhaust and is California emissions compliant. The RZ350 starts on the first kick, idles, shifts, runs, and brakes properly for an original RZ350 with low miles.

Unique opportunity to buy an all original, collectible, high performance 2 stroke. Will make a nice addition to a collection or provide miles of enjoyment to the vintage motorcycle enthusiast.

Any RZ worth collecting as original needs to be original. That means the fun go-fast parts do not apply, such as replacing the factory airbox with pods, bumping compression by milling the head, porting, expansion chambers, etc. That makes this particular bike very rare, as it appears to be in factory, unmolested condition. Pretty crazy given how many modified RZs we find in these pages, although if I must pick at nits, the handgrips are clearly not OEM and there appears to be a bit of rub rash on the fairing. This is a Buy It Now format classified on eBay, with an ask of $16,500 OBO. That is not the most we have seen in terms of asking price for this model, but for sure it is a big number. Check out all of the details here, and Good Luck!!

I Think I’m Turning Japanese – 1985 Suzuki RG500G Gamma

Mike 0

Spring has not yet sprung, but the ring-a-ding-ding sounds of our favorite smokers continue this week with a very cool RG500 Gamma. We don’t see enough of these square-four monsters on these pages, and rarer still in the black & red livery. This particular bike is on the ground in Japan, purportedly a full-power example out of Australia. It doesn’t matter to me what flag it runs under, because as an American this is one awesome looking 38 year old piece of forbidden fruit.

1985 Suzuki RG500G Gamma for sale on eBay

The RG500 magic starts with the engine – which is actually TWO engines. Think of the RG as a pair of independent, parallel-twin, 250cc two stokes, complete with independent rotary valve induction (there is a very thin, Mikuni flat slide attached to every cylinder), exhaust and crankshaft. Now stack those two on top of each other, one right behind the other. Connect the two cranks via gearing, and route that whole hot mess through the gearbox. You end up with a very powerful, very compact and dense package that can be placed far forward in the chassis for optimal weight distribution. And speaking of chassis, that would be a double down tube cradle style affair, exquisitely constructed in aluminum alloy. A 38mm, air adjustable front fork and Full Floater single rear shock complete the package.

From the seller:
SUZUKI RG500G GAMMA(Type HM31A, motor type M301)Export car full power (Australian specification) There is an aluminum caution plate on the left side of the frame.

* Buyers are responsible for paying transportation costs, taxes.
* An export cancellation registration certificate is attached.
* Tandem seat and manufacturer genuine 500 racing stand (at that time). If you wish,we will ship separately.

A full power RG500 is published as 95 HP – which is a fair amount of poke for a sub 350 pound (dry) machine. This gives the big RG its bona fide GP replica status, and general reputation as the fastest of the street-going two strokes. This one is safely tucked away in Japan, indicates nearly 23,000 miles on the KM clocks, and has been cared for and maintained in a manner that allows it to show very well indeed. Paperwork, shipping, taxes and importation hurdles notwithstanding, this auction has an opening ask of $36,500 USD (no takers yet) and a BIN of $48,000 USD. Check out all of the details here – including a walk around video – and Good Luck!!


Featured Listing – 2009 Aprilia RS125 Track Bike

Mike 0

Continuing in our recent form of fantastic two strokes comes today’s Featured Listing – a 2009 Aprilia RS125 Track Day bike. If you are a RSBFS reader and have seen comments in recent smoker posts you will know that there is nothing sharper for the track than a lightweight, focused two stroke. And when the bike in question comes from Aprilia – a company renowned for their small-bore racing exploits – and has been massaged and reworked to optimize track performance, you know you are looking at a bike that can punch well above its weight class.

Featured Listing – 2009 Aprilia RS125 Track Bike

The heart of the RS125 is a single cylinder, liquid cooled, reed valve inducted two stroke breathing through a single Dell’Orto carb. Power is fed through a wet clutch to a close-ratio 6-speed final drive. On the chassis side, the main attraction is a beautifully crafted box section aluminum alloy frame, to which is mounted very sophisticated suspension components. Out back there is an asymmetrical alloy swingarm with rising rate linkage, curved and braced to allow the exhaust to mount up high and tight for maximum cornering clearance. Up front the forks are oversize and upside down, mounted to a strongly braced frame stem. There is only a single disk up front, but it is a 320mm unit squeezed by a four piston, radial mount caliper; more than enough to aggressively stop the 280 pound (dry) package.

From the seller:
Up for sale is a rare TRACK ONLY Italian performance 2 Stroke moto. This bike is one of one hundred and fifty imported in to the U.S. in 2009. It is #17 out of 150. Purchased brand new from a dealer in CO in 2021 with 1 Km.

Bike has been my dedicated track bike for the 2022 season. It has been cleaned and serviced after each track day. Currently has 979km which is equivalent to about 607 Miles. Autolube feature so no pre-mixing. I run AMSOIL Interceptor as the oil and only 110 Octane Race gas. Bike is always garage kept and on a battery tender. Bike comes with a few extras.

More from the seller:
•Front and Rear stands
•Certificate of Origin
•Chicken Hawk Tire warmers
•Full printed Service Manual
•Original OEM Spain Plastics, Rear Seat and windscreen

•RG Frame Sliders
•Racing Windscreen
•Renthal Grips
•Adjustable Levers
•Lever Guards

More from the seller:

Location: Vacaville, CA

Contact Mikkel at 707-666-5556 or

Price: $8,000

These dedicated track bikes from Aprilia are very rare in the United States, but offer the most pure antidote to your track day addiction short of a full-on GP bike. With a snappy and zingy two stroke, light weight, and excellent brakes and suspension the RS125 when ridden properly can obliterate more street-oriented bikes many times its size. And while the Aprilia is a great mount for riders of any level, it teaches smoothness and momentum conservation much more so than a bigger bike. With automatic oiling and electric start it takes no more work than a bigger four stroke, without those pesky oil change and valve adjustment intervals. That is all win!

RSBFS fan Mikkel is offering this bike at $8,000. Located in California, the bike comes with some key additions (frame sliders, levers and guards) as well as desirable paddock accessories in the form of tire warmers and stands. The bike also comes with the original bodywork to maintain authenticity. Interested readers should reach out to Mikkel here, or give him a call. A bike like this does not come our way often, and if you are committed to improving your riding by attending track days there could be no better way to do so. Good Luck!!!


Two Stroke Three Peat! 1992 Suzuki RGV250 with CA title

Mike 5

Another day, another really cool 250cc smoker. And this one is properly titled and plated in the uber-restrictive state of California! While not as original/pristine as the earlier bikes, this 1992 Suzuki RGV250 is still one hot scoot ready for the canyons or the local race track.

1992 Suzuki RGV250 with CA title for sale on eBay

Like the Yamaha TZRs posted earlier this week, Suzuki moved away from a parallel twin to a V-twin format, providing tidy packaging and a more compact engine assembly. This allows for better placement in the chassis to maximize handling. And speaking of handling, as today’s seller has placed the registration on official non-operational status and used the bike as a track steed, he has also upgraded suspension and brakes. I recommend you read his advert text (below) carefully to see what is in store.

From the seller:
VJ22 RGV250 “M” model. This one is currently titled and registered Non-Op in CA with no fees. This bike has been upgraded with Andreani front cartridges and a Nitron R2 rear shock. It has a newer Tyga windscreen, a Tyga rear set, and Venhill steel braided brake lines. It currently has Dunlop Q3+ tires that have very few miles on them. The metal thing over the speedo is a lap timer mount for an AIM Solo lap timer. What is pictured comes with the bike, the lap timer does not. It is bolted on and can easily be removed if you don’t want it.

This bike was used as more of a track bike by me, which is why it was registered non-op. Starts easy, runs well. These little two strokes are screamers and are absolutely a blast to ride flat out. I am too big for it and not flexible enough to ride this bike anymore, a little age and several injuries. I would like to fund some upgrades to my track R6. I kept it CA titled and clear because these things are pretty dang rare to have on the streets in CA and always draw a crowd. “Mileage” is in kilometers, so the bike has a legit 7115 kms on it.

More from the seller:
The previous owner had an off in 1998 and it sat until I bought it in 2018. The only damage to the bike was body damage, hence the paint. I rebuilt the bike with the upgrades and used it as a track bike. There are some portions of the body that were fused with acetone prior to sanding and painting and with a close-up inspection, it is noticeable. With the Tyga rear set, the rear brake pressure is pretty light. I am not huge on stomping on the rear brake, but if your into that sort of thing you may need to work out a rear master cylinder that is a different diameter or something.

I would prefer a local pick up or I can meet somewhere, but if buyer wants to arrange shipping I will work with your shipper and entertain a bank transfer. I have some spares and take off parts. Mirrors, silencers, the factory rear set, the blinkers, stuff like that; it will all come with the bike. Pitbull stand is not included, but I will include a Pitbull head-lift stand insert that works with this bike.

Bike is located in Camarillo, CA

So while not really in the collector realm due to the non-original aspects, the RGV250 is still a very desirable model, providing a rare experience here in the US. This particular example has the ultra rare CA title, has seen some extensive upgrades for track day usage, and depending upon where the auction ends it looks to be a pretty interesting option for the pre-mix crowd. No bids with a $5k opening ask and only a couple days to go. Interested readers should check out all of the details here. Good Luck!!

Double Header – 1992 Yamaha TZR250R 3XV

Mike 1

If yesterday’s ’91 model year TZR250 in the muted grey colors didn’t quite get your motor running, how about a fresh-from-Japan ’92 model year in the bright and cheery white/red livery? This is a bike that looks like it is going fast even when it isn’t, and as a 250cc v-twin two stroke pushing a lightweight, aluminum-framed sport bike, it could actually back up those looks.

1992 Yamaha TZR250R 3XV for sale on eBay

The 3XV variant of the TZR converted the little 250cc two stroke from a parallel twin to a 90 degree vee – as was done by Suzuki with the RGV series. This allowed for the bike to be a bit narrower, generally improved packaging and weight distribution, and achieved perfect primary balance. While the latter is less important at the track for comfort, it does lead to higher revs and engine longevity and avoids heavy balance shafts or counterweights.

From the seller:
Recent acquisition from the Japanese market. If interested message me .New Michelin Pilots, runs amazing ,is nimble ,and unbelievably fast for a smaller displacement motorcycle. Japanese title and all paperwork included for transfer of title. 17800 kilometers. Trades for Ducati or MV’s or rare motorcycles considered. Video available upon request.

As a recently imported motorcycle (and no notes from the seller to indicate otherwise), this is a restricted home market machine. That means 45 buzzing ponies are the limit. De-restriction is possible, which generally consists of opening up the exhaust and intake. However – and RSBFS faithful help me out here – I believe that the updated 3XV platform requires ignition box changes to get beyond the government-mandated 45 HP limit.

This example looks to be very clean and quite free of corrosion or damage. There appears to be some minor scratching on the left side of the tail section, but not much else. There are some extra stickers on the bodywork, so hard to tell if those are covering up anything – but it certainly does not appear that way due to the rest of the condition of the bike. The KM clocks show just over 11,000 miles, and the bike comes with a Japanese title. Since it is over the 25 year mark, re-titling in most states (here’s NOT looking at you, California) should be possible. This looks cleaner than yesterdays example, with an opening bid of just $5k and a Buy It Now set at $11,500. Check out all of the details here, and Good Luck!!
