Cali-Titled Smoker: 1986 Suzuki RG500 for Sale

1986 Suzuki RG500 Gamma R Side

Look, I'll be honest. There are basically two reasons I like writing about Suzuki's two-stroke sportbikes. One, they're pretty funky, like this RG500Γ Gamma you see here that sports an engine with a very rare square-four configuration. Two, I get to use the cool Greek "Gamma" character which, along with the umlauted "O" for "Öhlins" are sometimes highlights of my week.

In building a bike meant to evoke their Moto GP weapons, Suzuki knew they needed an appropriate two-stroke powerplant, as that was the formula in fashion for top-level racing during the 1980's. The 500cc engine that resulted was an unusual, water-cooled square four that was basically two parallel twins geared to a common crank. At under 400lbs dry with 100bhp and a capable chassis, it was the S1000RR or Panigale of the day and was capable of humbling just about anything on the road.

From the original eBay listing: 1986 Suzuki RG500 for Sale

Brand New Paint, 19,717 KM, Lots of modifications. Big bore kit (570cc), aftermarket expansion chambers, carbs. bored oversize, performance air filter kits, GSX-R upside down forks and 6 piston calipers, RGV 250 rear swing arm conversion. California Registered

This particular Gamma is obviously enthusiast-owned and in good, although not completely original condition. The bike has been ridden 19,000 miles, so it's no garage-queen and those modifications are clearly intended to improve performance and take advantage of modern-ish suspension and tire technology to better harness that wild powerplant.

I happen to love the look of the updated suspension and wheels, although the missing front mudguard does irk me a bit. However many Gamma fans are purists, and a bike like this may have them apoplectic with rage at the violations. Depending on where the reserve is set, this could be a great buy for someone looking for the experience of a big two-stroke, without some of the limitations found in an older machine.

Clear Cali Title: 1992 Yamaha TZR250 RS 3XV for Sale

1992 Yamaha TZR250 L SideBuilt between 1986 and 1996, the Yamaha TZR250 came in a variety of forms, from the original liquid-cooled, parallel-twin "2MA" to the "3MA" that came along in 89-90 and featured an interesting "reversed" head that with the carburetors mounted on the front of the engine, exhausts running directly out the back to through the tailpiece. The final version made the same swap as Suzuki from a parallel-twin to a v-twin configuration for the "3XV" model as seen here.

In fact, the spec sheets for all of the little 250 race-reps of the period look like carbon copies of each other: 249cc two-strokes and six-speed gearboxes, with just different names and acronyms for the fancy power-valves fitted to each. On the little Yammie, we had a "Deltabox" alloy frame, Yamaha Power Valve System (YPVS) to beef up the underwhelming two-stroke midrange.

1992 Yamaha TZR250 Clocks

The complete package weighed in at about 280lbs dry and all the usual two-stroke superlatives applied. If you want pure cornering thrills and a bike that rewards skilled input, you can't go wrong with one of these.

From the original eBay listing: 1992 Yamaha TZR250 RS 3XV for Sale

This is a very rare bike with factory dry clutch, I would guess there are probably only two or three here in the US and this is the only one that I know of here in California with a California title and plate. This bike still has all the original 3XV fairings complete, original windscreen, stock pipes and silencers. Clear California title and current registration in hand. 18,596km, NO test rides, don't ask..

It's unfortunate the seller only includes three photos with the listing, but at least those photos are of decent quality. In the 90's, Yamaha seemed to offer some of the most restrained graphics treatments among the Big Four, and the lozenge-pattern along the flanks looks suitably vintage, but doesn't detract from the lines of the bike, with the yellow number-plate panel integrating smoothly into the design.

This one has covered a surprising 11,555 miles. Not exactly a touring bike, but pretty high for a bike like this. Considering the original fairings and screen, it's clear the bike has seen sympathetic ownership during its life. The seller appears to be the same one who offered up the TZR500 we featured back in April, so he clearly knows his Yamahas!

What the Doctor Ordered: 1998 Aprilia RS250 Rossi Replica for Sale

1998 Aprilia RS250 R Front

This is one of the nicest Aprilia RS250's we've featured recently, although the seller's claim that this is a "Rossi Replica" might be a bit of a stretch: Rossi was riding a 250 for Aprilia in 1998, but didn't win the title until 1999. In 1998 he was second, and prior to that, he was on a 125, but it made for a good title so I went with it.

An actual RS250 Rossi Replica would, of course, burn your retinas to look at...

1998 Aprilia RS250 L Side

The Aprilia RS250 used a 249cc, water-cooled two-stroke v-twin pulled from a Suzuki RGV250, although Aprilia used their own ECU, expansion chambers, and barrels. The revised motor was good for 60hp and the bike looked the business, with bodywork that suggested their 250GP machines. It was redesigned in 1998 to reflect the style seen here, with a pronounced humped-seat and a new funky-but-functional dash.

1998 Aprilia RS250 Dash

The beautiful asymmetrical swingarm gave extra clearance on the right-hand side for the shotgun-style exhausts and expansion-chambers. Brakes were the standard Gold Line Brembos found on every other freaking Italian sportbike of the period. Meaning they were designed to effectively stop bikes that weighed as much as 100lbs more than the bantam-weight Aprilia.

1998 Aprilia RS250 L Side

Designed for use by corner-carving heroes, or by people who wanted to pretend to be corner-carving heroes, the bike has very little in the way of creature comforts: like most two-stroke sportbikes, it doesn't even have an electric start. But if Sunday morning finds you sniffing two-stroke oil instead of coffee, nothing else will do.

From the original eBay listing: 1998 Aprilia RS250 Rossi Replica for Sale

Up for auction is this 1-owner, low mileage RS250 Replica.  This beautiful and rare example was purchased new in Germany by the current and original owner.  This machine was brought into the US legally under a racing exemption through the U.S. Department of Transportation and the National Highway Traffic Safety Admin.  All original paperwork and documentation from time of purchase, including service receipts.  Additionally, it has enjoyed some modest track use including several AHRMA events and track days.  NO expense was spared when the engine was fully rebuilt by Eurosports (PA), including but not limited to: re-plated cylinders, replaced pistons/hardware, welding of crank, new clutch assembly, etc.  

Bike has not been ridden for the past two years and the following service has just been completed: coolant flush, trans oil, brake fluid, new Michelin tires and more.  Bike comes with the original street hardware and owners manual. This bike has never been registered/titled/plated in the United States. It is considered an off road racing vehicle in the US. Other than original German documentation, there is no title. See photos regarding condition.  NO plastic (including windshield) has ever been replaced.

 1998 Aprilia RS250 L Rearset

While it does still have a headlight and the road equipment is included in the sale, obtaining a title for this could be tricky and the bike is already perfect for track use or racing, and has even been safety-wired.

Being that it is also in perfect, all-original condition, one might also be tempted to squirrel this away into your collection, or just display it in your living room where you can look at it and make "braaaaam, braaaaaaaaam" noises while watching Faster for the five-hundredth time...

Beautiful Bitsa: 1997 Suzuki RGV250 VJ23 Replica for Sale

1997 Suzuki RGV250 VJ23 Replica R Side FrontIf you're one of those RSBFS fans who turns up their nose at bikes of questionable pedigree, you should probably stop reading now. Or make sure your keyboard is all warmed up for the inevitable flood of vitriol that will inevitably spill forth once you've finished reading about this particular Suzuki RGV250 VJ23 replica.

1997 Suzuki RGV250 VJ23 Replica R Side Rear

The original RGV250 Γ "Gamma" replaced the parallel-twin RG250 with a water-cooled, 90° two-stroke v-twin in 1988 and went through various iterations until it was discontinued in 1998. Japanese home-market models were restricted to 45hp, but derestricted bikes or ones sold in other markets could see over 60hp, plenty to send the 300lb motorcycle shooting between corners. And corners was where this bike was built to live, with handling that lived up to its GP-replica looks.

1997 Suzuki RGV250 VJ23 Replica L Side

In building his little two-stroke mongrel, the builder combined the basic goodness and power of the VJ21 with its parts availability, added the running gear and slick swingarm from the VJ22, and cloaked it all in bulbous late-90's VJ23 bodywork. It's listed as a 1997, but the frame came from a 1990 bike so I expect that's how you'd register it.

1997 Suzuki RGV250 VJ23 Replica Cockpit

If you're a fan of the later style, this bike is perhaps a very wise choice as the 1997 RGV250 used an all-new 70° v-twin that shared virtually no parts with the earlier bike and parts are much more difficult to obtain. In addition, derestricting these later bikes is expensive if it hasn't already been done.

From the original eBay listing: 1997 Suzuki RGV250 VJ23 Replica for Sale

RGV VJ23 replica in exceptional condition

I started with a very strong running low miles 1990 Suzuki RGV 250 VJ 21 SP as it has 59 HP and is one of the more reliable RGV’s with parts still a plenty.

To make it handle a bit better and look trick I added the USD forks and Banana swing arm and 17” rear from the 1991 RGV 250 VJ 22.

To make the bike to look modern and exotic  the 1997 RGV 250 VJ 23 OEM body components were chosen and craftfully installed.

The tail section is not OEM and was made special for this bike (To spec) as I could not locate an OEM tail) all other body parts are OEM VJ 23 correct


1990 VJ21 motor /electronics, frame, exhaust, rear shock (SP version), and controls

Massive power of the VJ 21 SP model = (59 hp) dependability, reliability and parts availability of the VJ 21. (The VJ 21 SP model came with the adjustable rear suspension and increased power)   Note: The stock VJ 23 only had 45 hp.

This bikes is very fast.

To obtain the same power output from a stock VJ 23 you would have to spend over $2500 to derestrict ( 45hp to 59 hp) !!!!

The SP VJ 21 came out of the box with 59 hp STOCK!!

 1991 VJ 22 USD forks, very desirable / rare Banana swing arm and 17” rear wheel giving the bike great handling and good looks with the USD forks and rare banana swing arm. Triple upper is from a GSXR 600 to provide VJ 23 fairing stay clearance. (No mods required/ simply bolted on)

1997 VJ 23 OEM Bodywork, Tank ,Fairing , Fairing stay , Mirrors , Head lamp, Tail lamp, Driver and Pillion seat: exotic and modern GP look of the VJ 23.

All of these components are in exceptional condition and all work perfectly.

Bike starts, idles and runs very strong. It also handles extremely well and always starts first kick every time!!

Has a nice kick in the pants between 8k and 11K when the power valves come alive.

Low miles... 7300 Kilometers = 4700 miles

All of the parts have been gracefully installed without modifying the existing VJ 21 attributes / structure so if one so desires, they could return the VJ 21 to its original state. (Surprising how many parts easily adapt together/ parts are not simply zip tied with the exception of one here and there!!) Nothing was modified to make these parts fit…

  • Oil injection intact and fully operational (only high quality oil used)
  • Fresh set of NGK BR9ECMIX Iridium plugs
  • Fresh oil change
  • Fresh coolant and radiator flush
  • Front and rear brake fluid flushed and adjusted (Great stopping power)
  • New air filter
  • Newer Bridgestone Battleax tires front
  • NEW Bridgestone Battleax rear tire.
  • Steel braided front and rear brake lines.
  • 2 sets of keys
  • Carbs clean and function perfectly

I will include a set of OEM Suzuki RGV chambers and cans which will allow the exhaust to exit on same side (GP bike look).

1997 Suzuki RGV250 VJ23 Replica SwingarmSo it's obvious that, while this bike may be not be some all-original collector's item, parts are all from within the Suzuki family, and the seller has taken a "best of" approach to building this bike, taking the strongest, easiest to work on engine and combining it with more modern bodywork. I actually prefer the look of the earlier bike, but there's no question the VJ23 panels are very exotic looking, and I'd definitely fit the offered shotgun-style exhaust.

1997 Suzuki RGV250 VJ23 Replica L Side Rear

The question is: will the modifications turn off traditional Suzuki fans, or will they be excited by the enthusiasm and thought that went into this build and be willing to ante up for this bike? With 5 days left on the auction, bidding on this little mutt is up to $4,500 with the reserve, unsurprisingly, not yet met.

Dawn of the Repli-Racer: 1986 Suzuki RG250 for Sale

1986 Suzuki RG250 R SideSuzuki's RGV250Γ shows up on this site from time to time, but it's been almost a year since we featured that v-twin powered bike's predecessor, the RG250Γ. Two-strokes were the best way to get both power and light weight out of the same package in the 1980's and, instead of the later bike's v-twin, the RG250 was powered by a 54mm x 54mm [247cc] liquid-cooled, two-stroke parallel twin, along with a trick aluminum frame and the usual bunch of 80's acronyms and catchy names.

1986 Suzuki RG250 L Side Detail

AEC or "Automatic Exhaust Control" fattened the two-stroke's midrange, DecaPiston brakes had... four pistons, while PosiDamp forks had air-assisted preload. All very trick stuff for the period.

1986 Suzuki RG250 Front Wheel

Produced between 1983-1986, the earlier Gammas had a bit of Yamaha RZ350 not-quite-fully-faired look about them, but by 1985, the RG was starting to look like the whippy little two-stroke repli-racers we all know and love.

1986 Suzuki RG250 Dash

The resulting bike weighted in at 286lbs dry and put 45hp through a six-speed gearbox while rolling on 16" front and 18" rear wheels. lightweight aluminum frame perfectly square 54mm x 54mm 6 speed 16" front 18" rear.

1986 Suzuki RG250 Front

The change to a v-twin was likely made to make a narrower, slipperier bike to maximize the limited power available and to create a smoother bike: parallel twins are compact and less expensive to manufacture, but v-twins tend to vibrate less at higher rpms.

From the original eBay listing: 1986 Suzuki RG250Γ for Sale

Just imported from Japan this summer, this 1986 RG250 comes with a US title ready to be transferred into your name in your state.

This RG-250 is showing just 4262 original miles (6862 kilometers) on the odometer so it is a clean, low mileage bike but the bike was lacking 1 piece of Japan paperwork so it was dismantled and shipped to the United States and then reassembled when it arrived stateside. It's titled free and clear now in the USA but some final assembly like cables and electrical plug-ins and fluids, etc need to be finished before you can ride it. You can see from the video it's a running bike and it's complete and the fairing bodywork is original but maybe the front lower fairings are missing, I don't know, I'm not that familiar with this model, I can only compare it to my NSR250R bike. The seat is in good condition with only a small 1 inch split along the lower left side. Needs new paint around the brake reservoir but the triple drilled disc brakes and original paint make for nice features on this bike. Tank is straight and there is no crash damage anywhere; the bar ends and levers and pegs and turn signals all look normal but the left fairing attachment by the gas tank is broke (see pics). All in all a clean used RG 250 listed for no reserve. Someone is going to own it - why not you?

I can get great shipping rates (anywhere in California for $300 as an example) so don't let the cost of shipping keep you from owning this collectible Japanese two-stroke streetbike. This rare two-stroke motorcycle comes with a key and is already street legal titled in the United States in my name and ready to be transferred into your name just like any other vehicle title transfer.

The seller also includes a video of this bike showing running condition before it was shipped to the United States.

1986 Suzuki RG250 Rear Wheel

This certainly isn't in pristine condition, but looks to be relatively clean and complete, with low miles and a title. Bidding is active, but only up to about $2,700 with three days left on the auction. With a little love, this could be a pretty cool back-road blaster, and one that holds an important place in Suzuki's history.

Two-Stroke Resto-Mod: 1984 Yamaha RZ350 Kenny Roberts Replica

1984 Yamaha RZ350 L Side Front

While many motorcycle fans are sticklers for originality, I take a more flexible view: basically, if you make changes, even significant ones to the bike, but manage to maintain the spirit of the original, I'm probably on board. And while this Yamaha RZ350 isn't quite stock, the seller obviously wanted to stay close to the look and feel of the original, with suspension improvements that should make the bike even more fun to ride.

1984 Yamaha RZ350 L Side Rear

If you live in the US and want a sports two-stroke of recent vintage, you're likely looking at some tired ex-Japanese market bike imported through Canada and now of very questionable provenance. Or you're looking at an Aprilia RS250.

1984 Yamaha RZ350 Dash

Two-stroke fans here have found slim pickings in the last 20 years or so, but it wasn't always that way. Back in the 1980's, that glorious era of neon, Nagel prints, big hair, and slightly ridiculous motorcycle acronyms, two-strokes were still popular, and enough people cherished their RZ350's that they're some of the most accessible sports two-strokes available here in the US. Sure, there are some thrashed bikes out there, but it's not too hard to find well-preserved examples if you look.

1984 Yamaha RZ350 Fairing

Which is especially surprising, considering they were produced only between 1984 and 1985. The bikini-faired sportbike was powered by a 347cc two-stroke parallel twin that was evolved from the RD350, but added liquid cooling to the package, along with Yamaha's YPVS which, as you can probably guess, stood for "Yamaha Power Valve System."

1984 Yamaha RZ350 Engine

At the time, the RZ350 was a serious back road tool and was one of the best-handling bikes available at any price, and required rider involvement to maximize the two-stroke powerband.

From the original eBay listing: 1984 Yamaha RZ350 for Sale

Great bike that needs nothing, I’m selling to fund my Aprilia RS250 project. Specs below:


200 miles on fresh top end and crank rebuild. Crank was trued and welded, Wiseco pistons on 2nd oversize bore. OEM head gasket. Zeeltronic CDI (non- programmable). Genuine Keihin PWK 28 flat slide carbs, uni pod filters and quick turn throttle with custom cable and aftermarket kill switch. Banshee adjustable ignition timing plate (currently running +3 degrees from stock). Allspeed expansion chambers that were repacked and powder coated black (sound great, not too loud). Oversized aluminum radiator. The carbs are jetted properly (if not a little rich) and the bike runs great. Starts on the 2nd kick cold, idles nice, pulls hard and is extremely smooth. Setup for 40:1 premix and premium pump gas.


Aluminum FZ600 swingarm (professionally machined to fit in the RZ frame). Fox shock with ride height adjustment.   FZR wheels (new bearings, powder coated black). The sprocket carrier was machined for proper chain alignment with the wider rear tire. FZR forks (fresh rebuild),triple trees and clip-ons, tapered head bearings. FZR brakes front and rear, stainless rear line. New chain and sprockets, chain is a gold o-ring 520. New tires. The bike handles and stops very well.


All of the paint was redone with reproduction decals and professional clear coat. Reproduction solo cowl with bump pad. Inside of gas tank is rust free, it was professionally coated by a radiator shop. Manual style petcock. OEM seat with no rips or tears. Custom laser cut stainless bracket to mount the OEM fairing and gauges to the FZR triple clamps (looks factory). The frame has original paint and has a few minor scratches and nicks but overall is very presentable. I left off the horns and turn signals for a clean look but the wiring is still there if you want to add them. The rear fender was also eliminated and tail light tucked up a little higher.   Included are the stock rear fender and tail light bracket.

Full disclosure: The motor numbers and frame numbers do not match. The original engine cases had damage to one of the crank bearing journals and it was decided to use a different set of cases. Clean title in hand which matches the numbers on the frame. The damaged cases with matching numbers will be included. The odometer shows 2400 miles but I have no idea if that mileage is accurate or if they are even the original gauges. It doesn’t really matter since everything on the bike from the ground up is essentially new or rebuilt.

1984 Yamaha RZ350 Tank

Bidding is up to $3,999, but there's plenty of time left on the auction. The seller has obviously put plenty of work into it, but will purists balk at the changes?
