Featured Listing: 2009 Aprilia RS125

Nothing in American motorcycling circles screams "MEH" like a 125cc single cylinder beginner bike, even if it does have a paint job aping a world champion's race bike. That's a shame, really, as most of the motorcyclists on these shores end up missing the joys of light, flickable, surprising rides in favor of feeding the maw of the ever-escalating horsepower wars.

You end up missing things like this 2009 Aprilia RS125, a 275-pound flyweight two stroke that puts out almost as much power as legions of bigger, tamer four-stroke dual sports. True, it won't win a stoplight to stoplight contest, and its merits don't shine until you have clear road in front of you and you're near the top of the revs, but it will always reinforce the slow bike fast principle.

The seller has the bike plated in California, although it is on a non-op registration after it proved too much for his new-to-bikes wife and too little for his frame. Though the title is clear, it is entirely possible Cali will revoke the plates the next time it crosses the DMV's threshold. It should be good just about everywhere else, though, and is the perfect weapon to chase down clumsily ridden big bikes.

From the seller:

For Sale: 2009 California plated Aprilia RS 125 “Spains No. 1” edition. Price $4800, reasonable offers considered. Ready to ride.

Purchased in 2012 as a bike for my wife, we quickly realized that managing a two stroke 125 repli-racer as a learner bike wasn’t the best idea. That and the fact that this is a beautiful bike (and not wanting to have anything happen to it) I took the bike to ride. As the third owner, I put around 100 miles on it, mostly short trips to the Rock Store - one of our local bike hangouts. For my size, the bike was underpowered and undersprung, so it spent most of the time in our garage. I was told by the previous owner that the street components (harness, lighting, etc.) are factory Aprilia and all were installed by Aprilia technicians.

Ultimately, to make room in the garage, in 2016 fluids (coolant, fuel, engine oil and transmission oil) and were drained and bike was put in climate controlled storage. Recently, it was brought back, fluids refreshed, restarted and taken for a checkout ride.

Title: Bike has clean title with California plates, but is registered as PNO (planned non-operation) in 2014 since the bike was not being ridden.

Known issues: There is a slight blemish on the passenger seat and on the right hand side panel it there’s a ¼” mark in the sticker (see photos). What I would do if I were keeping the bike: Tires are serviceable for street riding, but for more lively canyon use, I’d replace them. Also, fork oil should be refreshed and the oil injector lines seem to be a little stiff so replacement will be in order at some point.

Rear view mirrors are removed but will be included with sale. No other accessories are included.

Bike is located in West Hills, CA

Price: $4,800 USD

At $4,800 it's most of the way to KTM RC390 territory, but is altogether more interesting, and for the right rider could be more fun. It's also worth noting that this bike truly is the top of the tech heap when it comes to two strokes, and is still cheaper than the older grey-market Japanese equivalents.

Featured Listing: 1986 Suzuki RG500Γ for Sale

Suzuki's RG500Γ "Gamma" is a modern classic, a bike from the tail end of the two-stroke sportbike era, at least here in the USA where lightweight, smoky strokers were gone by the mid-80s. At the time, it offered significant on-paper advantages over something like a GSX-R750: it was lighter and the 498cc engine made similar power and torque to the four-stroke 750. But the two-stroke engine was much more highly-strung, making it a more challenging bike to ride quickly, but that's exactly what two-stroke sportbike fans love about them. They relish the involvement required by the narrow powerband and the trail of heavy, oily smoke that drips from the four tiny exhaust pipes.

Why four pipes? Well the Gamma was powered by a square four engine that, although not actually based on the unit that powered Suzuki's Grand Prix machines, at least used the same format, with twin crankshafts and a pair of very compact Mikuni carburetors on either side. Of course, like all two-strokes of the period, it featured a power valve system, in this case Suzuki's AEC or "Automatic Exhaust Control" and a cassette-style six-speed transmission theoretically allowed quick changes to the gearing trackside. The aluminum frame resembled the GSX-R's, and the Gamma had hydraulic anti-dive forks at the front and a complex, rising-rate monoshock rear suspension that Suzuki dubbed their "Full-Floater" system. A 16" front and skinny 17" wheel out back seem odd today, but were fairly standard at the time.

This particular bike should be familiar to long-time readers, as it was posted up here a couple years back. The individual who purchased it has decided the time has come to pass the bike along and let a new owner appreciate the craftsmanship that has gone into it. Most Gammas look very much alike, as 99% of them originally were, or have been repainted, in the traditional blue-and-white Suzuki colors, with a few blue-and-red Walter Wolf examples thrown in for good measure. But this particular example was custom-painted and, lest you think the less traditional colors mask a bike that's been less than lovingly maintained, let's dissuade you of that notion right now: it was rebuilt a couple years back from the ground-up, and tuned by none other than Rick Lance. Basically, this bike has had a kitchen sink worth of upgrades thrown at it, as you can see from the seller's description, and the result may not be original, but is pretty spectacular.

From the seller: 1986 Suzuki RG500Γ for Sale

I have been blessed to own 3 of these legendary motorcycles. Out of the 3, this is the nicest and best out of my collection. I purchased this bike in October of 2016 from California. It was a recent build done by Rick Lance. I was talking to Rick at the time about doing a build with him in the exact format. However the cost was more and the timeframe was about 2 years wait. I came across this one on eBay and snatched it up. When it arrived it was nicer than the pictures detailed. Furthermore, it was listed as a 1985 and the California title reflected it as a 1986. The details are as follows:

This 1986 RG500 has ~1200 miles on it since being fully rebuilt in 2011 by Rick Lance from Lance Gamma lancegamma.com

It has the following features:

Motor: full motor rebuild including:
555 upgrade, GSX-R radiator, valve kit
Maranello transmission kit
Lance Gamma clutch upgrade
Lance Gamma TriPod air filter kit
Lance Gamma supplemental petcock
Lance Gamma pipes

Chassis, bodywork, etc:
Battery + oil tank conversion
Wheels ands rotors
Forks
Shock
Lance Gamma fiberglass bodywork with custom paint scheme

This bike is something special and unique

BTW– when Randy Mamola visited the previous owners home he autographed the bike on the gas tank, so that makes it even more unique!

The bike is the nicest you will come across. I have very much enjoyed it. I only put 200 miles on it since the purchase. It has spent more time sitting in the storefront window of my Indian dealership. My business circumstances have changed and I am looking to reinvest in my business.

I have a service manual and extra windshield that will go with the bike if desired.

I will ship worldwide on your dollar. Feel free to contact me for pictures, videos, or call me if you desire to discuss specifics.

As the seller states, this bike has covered just 200 miles since it was last seen on RSBFS. Frankly, I wasn't a huge fan of the looks when it was posted previously, but the photos that feature the bike indoors, in less glaring light, show just how classy and striking the paintwork is and it's sure to stand out in any crowd [?!] of Gammas... I generally prefer the Walter Wolf colors for the RG500, but there's no denying the quality on display here. It is posted on eBay, no reserve, so submit a bit and take a chance!

Featured Listing: 1990 Yamaha RZ350

As far as two strokes go, the RZ350 (also known as the RD350LC in some geographies) needs no introduction. Available in various markets and configurations between 1983 and 1995, this peppy two stroke was legally imported the world over - including the United States. And while U.S. readers might be most familiar with the bumble-bee black/yellow Kenny Roberts commemorative edition - or even the red/white Yamaha racing livery - there is a very special and very rare in the US model that was released in Yamaha blue. This 1990 RZ350 out of Canada is one such example.

Featured Listing: 1990 Yamaha RZ350 in Canada


As is undoubtedly known, the RZ350 is really the last of the factory imported two strokes when it comes to the US market. Born of a time when air-cooled 550cc four strokes ruled the roads, the RZ350 was a generational evolution of the older RD350 smokers. With a liquid cooled parallel twin cylinder format, the RZ350 introduced Yamaha's first exhaust power valve - which helped to quell the peaky nature of two stroke power delivery. And unlike the US which was blessed by exhaust chambers that contained catalytic converters (read: restrictive and heavy), the rest of world models made due with more standard - and powerful - expansion chambers. Talented riders able to keep the RZ on the pipe could wreck havoc with riders of heavier four-stroke machinery. And with a trellis-style perimeter frame, decent suspension and triple disk brakes, the RZ was a delight both in the canyons as well as on the racetrack.

From the seller:
I am selling my 1990 Yamaha RZ350 after purchasing it in April of 2011. The bike is located east of Toronto, Ontario, Canada, and the odometer reads 20,610 km., or 12,806 miles. To my knowledge that reading is accurate. There might a handful of miles more because I replaced the odometer cable after noticing the original had expired on my way back from a ride about five years ago.

Again, to my knowledge, the bike is bone stock, and hasn't experienced an engine refresh, nor has it been raced or used for track days here in Ontario. The bike starts and runs perfectly, and the tires have fewer than two hundred miles on them, and has received a recent battery.

More from the seller:
The previous owner admitted that the bike has experienced the ubiquitous driveway tip-over, and I have tried to document the resulting scratches in the photos. Having said that, the bike presents very well, and the plastics are in very good shape. One of the mounting tabs was broken and when I bought the bike a large washed held the inside of the right fairing to the frame. I have since used a fairing repair plastic to repair that blemish, which I show in a couple of the photos. The decals on the bike are all there however, because of the way Yamaha chose to put the mounting holes through the side decals they have shifted in a couple of small areas.

There are about four pin-sized chips on the gas tank, but because they're so small I have no idea what could have caused them. The fairing, while complete and sound, has a couple of small stress cracks which can't be seen unless during a thorough inspection. There are two small areas (about the size of a quarter) on the fairing where it almost seems like the paint has worn off, but there are no cracks or abrasion there.

More from the seller:
The right side mirror, while replaced (I'm told) after the tip-over, had lost its collar where the mirror swivels. Because a new mirror is now unobtainium through Yamaha Canada I attempted to repair it with the same fairing repair plastic I used to fix the fairing stay. It looks OK, but if you can source a new or good used one, I leave that to the buyer. There was a crack at the tip of upper cowling where it meets the windscreen which I repaired with the plastic compound and a small strip of fibreglass. It is painted and not noticeable under normal scrutiny.

I rebuilt the front brake master cylinder in 2012, and has not needed maintenance since. The
radiator has been topped up with Water Wetter, and the bottom end has been drained and refilled with
fresh lubricant. The bike also has new spark plugs installed

I won't attempt to review the history of the RZ350, as there are many sites online that can fill you in on that. However, this is the last year Yamaha made this model, and it wasn't exported to the U.S. It's odd, but even Yamaha Canada doesn't have a record of this model in spite of the fact that they clearly were imported into Canada.

The bike, while not perfect, is a very good example of the model.

Price: $4400 (USD)

So what you are looking at here is a strong example of the RZ lineage. While the US only received the RZ in 1985 and 1986 (and California only in 1985), the rest of the world continued to enjoy this stout little smoker for many years thereafter. There were not too many changes to the hardware or output after the late 1980s, but the bones of this bike were so good that the model continues to be sought out to this day. This bike appears to be honestly presented by a fellow rider, which is always a benefit in a world full of short-term flippers. Purists will be quick to point out that the 1985-86 models are the most collectable from an investment perspective, but when it comes to riding finding a later variant that has been ridden and cared for is much more important. This sub-13,000 mile example ticks all the right boxes when it comes to a rider. No, it is not a museum piece or garage queen. Yes, it proudly wears the scars of some use. But most importantly, it is priced competitively for what it is. If you are looking to bolster your fleet with something that is worth hanging onto, this might just be your lucky day. Ping Brent if you are serious - and blue smoke and a silly grin will be just a few thousand RPMs away!

Worth the Trip: 1983 Suzuki RGB500 for Sale

This time of year, really interesting sportbikes can be a little thin on the ground, so our online searches naturally take us farther afield. In this case, all the way to Japan for a 1983 Suzuki RGB500 that was the Grand Prix racing inspiration for the two-stroke RG500Γ. This Mk8 version was highly-developed, although the earliest iterations of the bike were notoriously brawn-over-brains machines, with plenty of power but sometimes terrifying high-speed handling...

Suzuki's initial foray back into Grand Prix competition in the early 1970s was built around a production-based, water-cooled parallel twin borrowed from their T500 Titan, which saw limited success. Something different was needed if Suzuki wanted to win, and that meant the development of a brand-new four cylinder engine that featured a pair of cranks, disc valves, and the now famous square-four architecture. The new four-cylinder machine was first competed in 1974 and won its first Manufacturer's Title in 1976, then went on to dominate Grand Prix racing for years, and actually drove the shift from four-stroke machines to smokers: if you wanted to compete, you made the switch. That change defined prototype motorcycle racing up until 2002, when rules changes specifically intended to allow four-strokes to compete on more equal footing were introduced.

The original design for Suzuki's new square-four used front and rear cylinder banks that were the same height and made 110hp, although later versions used the more familiar "stepped" arrangement familiar to fans of the Gamma and made even more power. Suspension and tire technology took a while to catch up with the engine's brutal performance: 120hp may not sound like much today, but two-strokes deliver that power in a famously abrupt manner, and the early machines ate tires and chains with startling regularity. By 1982, the bike weighed 238lbs and produced over 120hp, with top speeds of up to 170mph and the RGB500, helped along by talented riders like Barry Sheene and Randy Mamola, was a dominant force in top-level motorcycle racing throughout the 1980s.

From the original Yahoo! Japan listing: 1983 Suzuki RGB500 for Sale

Please, no jokes about the listing: I ran this though Google Translate so the original seller isn't responsible for any atrocious syntactical mistakes. Although I'm really interested in "a mustard and test course." Obviously, potential buyers won't be worried about the need to register their purchase, since this isn't a street bike. You'd just need to figure out whether to to race or display this bit of history.

Race ready: Deus-restored 1973 Yamaha TD3

As a road racing icon, the Yamaha TD series really needs no introduction. The internet is positively lousy with rhapsodic accounts of its achievements on a racetrack in the hands of big names and amateurs alike. Not just screamingly fast, the 250cc parallel twin TDs were reliable as the sunrise, which made them very hard for contemporary iron to top.

1973 Yamaha TD3 for sale on eBay

They're still darlings of vintage racers, aided by simple air-cooled architecture and widely available parts. This 1973 Yamaha TD3 has been made race ready by Woolie's Workshop, an arm of the Deus Ex Machina classic bike franchise. It has been updated with a front disc brake and an Ohlins steering damper to edge it closer to modern spec.

From the eBay listing:

Fresh from Deus’ Woolie’s Workshop

c.1973 Yamaha TD3 250cc Racing Motorcycle

The mainstay of 250cc and 350cc class racing at national and international level for many years, the twin-cylinder two-stroke Yamaha well deserved the title of 'privateer's friend'. The 250cc TD2 arrived in 1969, replacing the TD1C, and immediately proved capable of winning Grands Prix, privateer Kent Andersson triumphing in the German round at Hockenheim that year, one of Yamaha's most significant classic victories. The giant leap forward from the TD1C had been achieved thanks to a comprehensive redesign that saw the porting and exhaust system updated, superior Mikuni carburettors adopted and the chassis, suspension and brakes greatly improved. Looking like a scaled down Norton Featherbed, the TD2's chassis was a development of that used for the RD56 works racer. Kel Carruthers on the works Benelli 'four' denied Kent Anderson the 250cc World Championship in 1969 but the following year the TD2 came good when Rod Gould, riding a works machine entered by Yamaha Motor NV of Holland, took the title.

The TD3 was an evolutionary step forward in the long line of successful Yamaha air-cooled two-strokes, and as it happens it would also be the last in its line. Released by the Japanese marque in 1972, the TD3 benefitted from a horizontally split crankcase, which holds the 247cc internals, producing about 50bhp and a redline in excess of 10,000 revs, which can propel the diminutive little racer’s 230 pounds to blistering racing performance figures with incredible reliability.

Fresh from Deus Ex Machina’s “Woolie’s Workshop”, this 250cc Yamaha 2-Stroke screamer was built to be competitive. Like all the builds out of Woolie’s Workshop, it has that ‘final 5%”, which is always the most assiduously earned and separates the great bikes from the mere good ones. Every component was addressed, rebuilt, refinished and restored with Woolie’s exquisite attention to detail, including engine, gearbox, and all cycle parts. Upgrades include the Ohlins steering damper and disc front brake. Built to race, but with no track time since the build, this is a fantastic opportunity to own a custom purpose-built race bike to be a class winning AHRMA machine. Tuck in, hold on, and safety-wire your bum to the seat….

Sold on a Bill of Sale.

The bike has been run but not raced since it was finished, so it is just waiting for a vintage racer to give it the neck wringing it so richly deserves.

Two stroke restomod: 1986 Suzuki RG500

The problem with owning classic sportbikes is that even in their best shape, they perform like they would have 30 years ago, which can be a terrifying affair if you're used to modern suspension and tires. Couple that with a take-no-prisoners 500cc two-stroke powerband, and you're really playing with fire. This 1986 Suzuki RG500 has had those concerns addressed, with mods to allow it to run modern tires and reworked suspension and brakes.

1986 Suzuki RG500 restomod for sale on eBay

The work was done by renowned RG500 tech Rick Lance, and the seller says no stone was left unturned. The bike was taken down to the chassis and gone over from top to bottom. The forks have been rebuilt and the anti-dive bypassed, and the engine has been treated to a mild tune, including a rare set of aftermarket expansion chambers.

From the eBay listing:

1986 Suzuki RG500 Gamma. Full Rick Lance Gamma build "resto mod" from the frame up, in excellent condition, mods inc 17 inch wheels, GSXR brakes, Fox remote shock, upgraded forks internals, anti dive block off, plus all the usual Lance Gamma mods, filters, taps, clutch. Rare Tommy Crawford expansion chambers, motor has stock bore with mild tune, lightweight bodywork with single seat with excellent stock style paint scheme, less than one thousand miles since full build including the engine, suspension, gearbox, etc etc, as you would expect from a Rick Lance build it runs and rides perfectly, carburation is spot on pulling cleanly from idle to the red line.

Hard to find these now especially in this condition with everything being practically new, gets lots of attention where ever it goes, sounds amazing, from an era when GP bikes were 2 strokes and four cylinders there will never be anything like it again, own a piece of history!

Clean GA title in my name, located in North Georgia USA Can assist with shipping

The price is an eye-watering $26,500, which is staggering even as the price of nice stockers is climbing. That said, if a modern-style two-stroke superbike is your thing, we doubt you could build your own for cheaper.
