Vintage Racer: 1970 Yamaha TR2 350 for Sale

Introduced in the late 1960s as an over-the-counter racebike, Yamaha’s TR2 was based on the road-going R3, and was extremely popular among privateer racers of the period. At just 253lbs dry, the bike was lightweight and, with a nearly square 61mm x 59.6mm bore and stroke that worked out to 348cc, the little air-cooled, two-stroke parallel-twin put a claimed 55hp through a five-speed gearbox.

The huge drum brakes at both ends seen here were difficult to adjust correctly and are obviously not as effective as discs that would have likely been fitted to period racers as soon as they could get their hands on a set, but look very shiny!

Restored to an excellent condition. Matching numbers. This very rare racebike have been completely overhauled with a lot of brand new parts as new cylinder barrels and pistons and an overhauled crankshaft, new Koni shock dampers, tires etc.

Transport can be arranged to most EU countries as I can deliver it by myself for actual costs for petrol and ferry tickets and, depending of distance, overnight costs at a cheap hotel. Transport outside Europe must be arranged by the buyer himself. I will make it ready for shipping with a crate and good wrapping.

Currently located in Sweden, this bike is in extremely nice condition, considering the age and the hard life most racebikes have endured, and appears ready to run or for display. Starting bid is $9,900 with no takers and very little time left on the auction, so move fast if you’re living room needs redecorating!

1999 Laverda 750S with under 1,000 miles !

In the late 1990’s Laverda was re-incarnating their past glory and made some of their best big upright twins and triples, before being purchased and then shuttered by Aprilia.  Presented here is a rare yellow and very late 750S, sparkling with only 994 miles.  Could be the nearest thing to a brand new Laverda out there.

1999 Laverda 750S for sale on eBay

 

The basis of the 750S is the company’s signature twin, but updated with 4 valves per cylinder, a balance shaft, fresh air intakes and Weber fuel injection.  The powerplant inspired reviewers to put the excellent twin-spar alloy frame through its paces, and the premium Paoli suspension was worthy.  The company was known for not scrimping on components, as the gold line Brembo brakes and Marchesini wheels testify.  The fairing favors the solo rider with a snug seat and step up for the pillion, and the upturn of the dual exhausts is delayed to accomodate the rather rear-set pegs.

 

Evidently on display almost since new, this 750S still needs its break-in miles.  You’ll have to lift the seat to add fuel, since the 750S was an early convert to underseat fuel and high airbox.  Finishes are unmarked and somehow the bike escaped the garage elves that usually plot a tipover or dent.  The seller relates that he is the second owner, and keeps it simple in the eBay auction:

1999 Laverada 750S with 994 original miles (1598 Kilometers) in like new condition no damage ever. Temperature and humidity controlled environment, on battery tender and covered. Starts and runs strong. Everything works, no leaks. Pictures speak for themselves.

 

At the time, European manufacturers were reeling from eastern competition, and couldn’t hope to turn the clocks back.  Like many, the Laverda response was reverential to past glories, and a competent if not class-winning performer.  Great design and top components make for a worthwhile experience, though at this point one would have to be mindful of the parts availability question.  But if you have the bug for a classic Italian, why not pick one that looks showroom new ?

Hat on Backwards: 1989 Yamaha TZR250 3MA for Sale

Competition between the Japanese manufacturers in the 250cc sportbike class was fierce, with each trying for some small advantage in terms of performance, given the limited displacement and government-mandated power cap. On paper, they all seem to follow a pretty standard template: a compact two-stroke twin cylinder engine, power-valves of one sort or another, and an aluminum beam frame. But each manufacturer went their own way trying to maximize performance within those fairly narrow parameters. While development eventually led to the NSR, RGV, and TZR all using v-twins, there were a few experiments along the way, and today’s TZR250 3MA represents an interesting attempt to solve the packaging issues inherent in two-stroke design.

Obviously, two-stroke engines are very compact by nature: with no overhead-valves or cams, they’re short, simple, and very light. But while the exhaust expansion chambers required for a performance two-stroke may not weigh all that much, their bulging shape takes up valuable real estate in a motorcycle. The famous “gull arm” swingarms of the period were one solution to the problem and allowed the chambers to tuck in close to the centerline of the bike to maximize cornering clearance. But the 3MA version of the TZR250 went a different route by reversing the cylinders so that the carburetors were at the front, with the exhausts exiting directly out the rear of the bike instead of curving around the sides or underneath. The bulbous expansion chambers fitted neatly into the seat, with the exhaust exiting through the tail.

The design was eventually replaced by the v-twin 3XV version introduced in 1991 after just two years, so the experiment can be considered a bit of a failure. But there’s nothing inherently wrong with the idea, and this is one of my favorite bikes of the era, at least in terms of looks and the weird factor: it’s my deep and not-so-secret shame that I haven’t ridden one yet, but here’s hoping that the stars will align and I’ll be able to find a decent California-titled example when the time is right. Scouting around the message boards, it seems that the bike’s reputation for poor reliability is exaggerated but, as these were not often seen anywhere outside of Japan, parts availability will prove difficult.

From the original eBay listing:  1989 Yamaha TZR250 3MA for Sale

The parallel twin reverse cylinder version. The bike is imported from Japan. Not registered yet in the U.S. This bike is sold without title. (NO TITLE) Start engine. Original Cowl. New Aftermarket Front fork innre tubes. Dragging brakes. Need to change tires (flat tire) and a battery. Some scratches and rust, so look carefully all pictures and video. This motorcycle is 28 years ago. Sold as is.

11271km (7003mile) LOW MILE. Sold as is with NO warranty NO refunds NO return. Buyer responsible for vehicle pick-up or shipping to your location. (ITEM AT CARSON NOW)

There’s also a helpful clip of the bike starting, running, and revving. The seller’s English is a bit limited, but it looks like the bike runs from the video and just needs a little TLC: a brake rebuild, new tires, and some minor cosmetic issues. Normally nothing you’d find shocking in a 28 year old motorcycle, but make sure you’re prepared to troll eBay and use Google Translate to track down parts to keep this running. It’s certainly not pristine and it’s not the cleanest example we’ve featured on this site, but if the price is right, it won’t take all that much to get this one on the road. Obviously, the usual titling issues apply, so I doubt this bike will remain in Southern California.

Restored Replica: 1984 Yamaha RZ350 for Sale

If you live here in the US and have a hankering for a two-stroke sportbike the choices, assuming you don’t want to monkey about with a grey-market import, are few and far between. 70’s two-strokes were relatively light and nimble, but still limited by the suspension and frame technology of the time, and by the mid-1980s, they’d been legislated out of existence, leaving this Yamaha RZ350 to make a final stand against the inexorable tide of four-stroke motorcycles. With blacked-out engine and frame, that striking black and yellow “bumblebee” paint, bikini fairing, and the “Kenny Roberts” signature, the RZ350 represents the very last of the old guard before “sportbikes” were codified into the narrow, very focused form we see in today’s motorcycles.

Produced for a very short period between 1984 and 1985, the RZ350 was a follow up to Yamaha’s RD bikes. It was powered by a 347cc two-stroke parallel-twin that added liquid-cooling to the successful formula, along with the “Yamaha Power Valve System” or “YPVS.” Powerband is typically two-stroke-y, even with the benefit of the YPVS power-valve, but the additional displacement helps some, compared to the all-or-nothing 250s. Weighing in at just 370 pounds or so with gas in the tank, it will still shake a leg on spirited backroad rides and can surprise modern machines, although tire choices for the skinny 18″ wheels will limit ultimate grip…

The seller claims that the bike has been restored from top to bottom, including a full engine rebuild, and it also includes a full-fairing that appears to have been a popular period accessory, considering the number of RZ350s fitted with them that come up for sale.

From the original eBay listing: 1984 Yamaha RZ350 Kenny Roberts Replica for Sale

Here is a beautiful restored 1984 RZ350 Kenny Roberts. The numbers are matching with a clear title in my name. This bike has a low production number of 223.  I have owned this bike for 6 years and have hardly rode it. It sat getting looks more than riding so its time to turn it loose. This bike has been completely restored. The engine has been professionally rebuilt from top to bottom. It runs and rides beautiful. There is less than 500 miles on this bike since it has been redone. As you can see it has a full fairing kit. The engine is stock with DG pipes and mild carb jetting. This bike is a real head turner where ever I have taken it. Probably the nicest RZ350 you will come across. Take a look at the pictures.

Bidding is very active on this one, and up to just over $7,000 with about 24 hours left on the auction. It’s certainly possible to find an RZ350 for less but, unless you stumble across some pristine, low-mileage museum-piece that will probably need a full restoration if you plan to ride it regularly, you’re unlikely to find one nicer. Well-reviewed when new and very popular now, the RZ350 neatly straddles the modern and classic eras, with clearly vintage sportbike style, light weight, and a liquid-cooled two-stroke punch. If you’re looking for US-legal two-stroke performance, this is just about the only game in town, and this example looks to be one of the nicest around.

Mark 1 – 1995 Aprilia RS250 Loris Reggiani Replica #275 of 500

The fact that it’s offered by a SoCal preparation shop specializing in Suzuki might be a reminder that the Aprilia RS250 used the 249cc two-stroke twin from the RGV250.  As enhanced by Aprilia’s intake, top end, and exhaust, the RS250 had power that put 4-strokes with triple the displacement to shame.   This first-year race replica has low miles, excellent cosmetics except for one faux pas, and a newly rebuilt engine.

1995 Aprilia RS250 Loris Reggiani Replica #275 for sale on eBay

Commemorating Aprilia veteran Loris Reggiani but capitalizing on Max Biaggi’s string of MotoGP championships, the RS250 brought GP technology to the showroom floor with the sculpted aluminum-magnesium alloy frame and swingarm, and carbon fiber seat subframe.  Bigger-bike Marzocchi suspension and Brembo brakes alert you to the possible speeds.  The full fairing is sleek and completed by details like factory billet rearsets.

 

Another victim of too many bikes / too little time, this RS250 has under 6,000 miles and looks great except for the right seat fairing, which might be remedied with a decal kit.  Not sure it’s the best thing on a low mile machine, but the fresh engine rebuild will require break-in and tuning, as the owner states in the eBay auction:

But probably the BEST THING about this bike is that it just had a full rebuild – crank, carbs rebuilt, pistons (rgv) new seal kit. Easy said and done over the internet  but i have photo’s to prove.
The bike is supplied with full jollymoto pipes, but oem ones are included (seat,rear passenger brackets )
Owners books (both keys) and original loris poster with sales advertisement’s
Bike does start but will need to be run in and maybe slightly tuned once its run in.

 

The small print for the RS250 included a powerband that doesn’t begin until 8,000 rpm, so there might be a learning curve there.  Ready to ride at 350 lbs., handling is sharp and the brakes are world-class.  Aprilia’s meticulous fabrication make the RS250, especially in the race replica, an exciting find…

Iron Curtain: 2005 MZ 1000S for Sale

2005-mz-1000s-l-front

Looking a bit like Aprilia’s Falco, the MZ 1000S was a high-end sport-touring motorcycle from a largely forgotten East German manufacturer that was powered by a big-bore parallel-twin engine. What could possibly go wrong? Well, not much really: as the seller mentions, parts to maintain the 1000S are available online, they’ve got a good reputation for reliability, and are apparently relatively easy to service. If you’re looking for something quirky and practical, with real-world performance, this might be worth a look.

2005-mz-1000s-front

Unfortunately MZ or Motorrad und Zweiradwerk is relatively unheard of outside vintage biking circles and fans of weird 90’s bikes powered by Yamaha singles. And even if you know the name, you might associate it with agricultural-grade, commuters and smoky two-strokes, which is hardly the image they were trying to present with this upmarket machine. More likely, they’d want you to remember their racing roots, and the fact that MZ two-strokes developed by Walter Kaaden basically set the standard for two-stroke performance and dominated the smaller racing classes between 1955-1976. The Japanese really only broke their stranglehold when racer Ernst Denger defected and took the brand’s racing secrets to Suzuki…

2005-mz-1000s-dash

Parallel-twin engines aren’t found in too many premium motorcycles these days: they’re reliable and very compact, but tend to vibrate badly as displacements increase. Just ask Norton and Triumph… But with modern balance-shafts, vibration is manageable, and parallel-twins offer up the character and midrange of a v-twin without the packaging challenges, and the MZ’s engine was backed by a six-speed cassette gearbox. Made for just three years before disappearing, along with the rest of MZ, the bike received positive, if not glowing reviews.

From the original eBay listing: 2005 MZ 1000S for Sale

You are bidding on my 2005 MZ 1000S “sport touring” bike. This bike is in great condition with very low mileage, a little over 2,000 miles,and ready for thousands more. This bike is totally stock with no mods, and really a steal for what you are getting. There are many “Chinese” bikes going for this price, but you get real German engineering/quality with this one. Here are the details:

This bike is in great shape, and I just had the following done within the last month. All oil/filters changed to factory spec Silkolene products, as well as brake & clutch fluids. Battery replaced at the same time, so this bike is ready for many miles. Starts right up,and runs though the 6-speed cassette transmission with no issues. Previous owner swapped out the gearing from factory original 17/43 sprockets to Vortex 16/45 sprockets to aid in upper end tractability. I do not have the original; sprockets, but they are easily obtainable on eBay if desired. The original turn signals were replaced by the previous owner, and I do not have the originals.

Cosmetically the bike is in great shape with a small amount of scratches in the factory paint here & there, but by no means rough. Hard to actually photograph to be honest.

Parts are easily obtainable from Grahams Motorcycles in the UK, and a lot of the the consumable items such as sprockets, brake pads,filters are readily available on eBay. Original factory owners manual included. Clear title ready to transfer.

Overall a really nice bike that will not get “lost in the crowd” of also ran sport bikes. Please ask questions, as all sales are final, and shipping transport must be completed within 2-3 weeks unless prior arrangements made. A Paypal deposit of $250.00 due within 48 hrs of auction’s end, and full payment within 7 days. Also, please make sure you clear it with your wife/girlfriend/boyfriend /dog/cat before bidding. Thanks!

The Buy It Now price is listed at $4,499.99 which, aside from looking like it belongs in the window of something on a used-car lot, is a pretty screaming deal, considering the performance and rarity. It’s not going to offer cutting-edge performance, but that was never the intent. Instead, it’s a mature sportbike you can ride to the twisties, then through the twisties, without needing a chiropractor at the end of the day.

Spooky Sportbike: 1998 Laverda Ghost Strike 668 for Sale

1998-laverda-ghost-strike-r-front

The Zane-era Laverda Ghost and Ghost Strike are extremely rare here in the USA. They were designed to fill the same niche as Ducati’s Monster and provide a profitable, parts-bin naked that would help put the struggling company into the black. The seller claims that the bike is “light, fast, loud, and powerful” and he’s probably mostly correct. At around 420lbs dry, it is relatively svelte and that exhaust is definitely not stock, so it’s likely pretty loud. The Ghost Strike generally came with a dual-exhaust, but this aftermarket two-into-one set up should save a bit of weight over the stock system in addition to increasing noise and power. Handling is excellent so the bike will definitely be quick down a twisted ribbon of asphalt, but “powerful” might be a bit of a stretch: the air-cooled 668 parallel-twin engine was a pretty ancient design and notably down on power compared to its competition from Bologna, with a claimed 70hp output.

1998-laverda-ghost-strike-r-rear

A quick look at the “gas tank” reveals something interesting: a lack of a filler cap. That’s because you’re really looking at the airbox and the tank filler is under a locking panel in the tail, which should be a conversation-starter anytime you’re gassing up. These bikes may look a bit like someone ripped the fairing off a CBR, but they’re very quirky machines that stress handling over power. The standard Ghost used a trellis frame similar to the Ducati, although this Ghost Strike features a beam frame that it uses identical geometry and is shared with the fully-faired 750S and Formula models.

1998-laverda-ghost-strike-airbox

From the original eBay listing: 1998 Laverda Ghost Strike 668 for Sale

Real deal.  Made in Italy. Rare and unique Laverda Ghost Strike 668.   Aluminum frame, fuel-injected, air-cooled parallel twin.  Carbon exhaust, Brembo brakes, etc.  Top of the line components.  If you want to ride something no one else has, this is for you!   Runs, rides and shifts perfectly.

Beautiful bike in great condition.  Never dropped.  Very slight imperfections from normal use.  Just had starter and flywheel replaced with OEM parts.   

This bike is light, fast, loud and powerful! 

The bike is missing passenger accommodations and its stock mirrors, but it does look better with these simple bar-end bits anyway. There are just a few hours left on the auction, with bidding up to $4,000. Certainly, a Monster will give you more bang for your buck, with much greater straight-line performance and parts availability. But handling from that Nico Bakker frame is famously good and these are rare as hen’s teeth, especially in the USA. If bidding stays low, this could be a very cool buy for someone with a desire to be a bit different.

“You Sending the Wolf?” 1986 Suzuki RG250Γ Walter Wolf for Sale

1986-suzuki-rg250-ww-r-side

The parallel-twin precursor to the well-known RGV250, the Suzuki RG250Γ “Gamma” was built between 1983 and 1987. Dry weight was a claimed 286lbs, helped by the aluminum frame, so the bike’s 45hp can still move the bike down the road smartly. The little Gamma was styled to match the RG500, and was packed with technology to rival its bigger brother: dual front disc brakes, anti-dive front forks, Suzuki’s Automatic Exhaust Control power-valve, and a six-speed gearbox. Tires are shockingly skinny, especially the 18″ rear, but the low-mount exhausts look surprisingly modern on this classic sportbike.

1986-suzuki-rg250-ww-front

Styling is a bit slab-sided, but is helped here by the dark blue and red Walter Wolf colors, while the “W” branded gauge faces add a bit of flash to the otherwise functional dash. Although he sounds like the villain of a spy thriller, Walter Wolf was an Austrian-born, Canadian businessman who sponsored several Formula 1 racing teams in the late 1970s and then touring cars in the early 1980s. How they thought to use a limited-production motorcycle to advertise the brand is anyone’s guess, but it did make for a good-looking machine.

1986-suzuki-rg250-ww-dash

Mileage on this example is very low and, although the bike isn’t perfect, is in very good, original condition, aside from the stingers mentioned in the listing. Even the foam instrument-surround looks solid. The seller has been importing grey market Japanese cars like Skylines and Kei-cars and for a few years now, and appear to have branched out into motorcycles more recently.

This bike only has 4,836 ORIGINAL MILES! The Suziki RG250 Gamma was never originally offered in the U.S., but now that it’s 25+ years old, we’ve been able to legally import it.   It’s 100% Federally Legal and registration is like any other motorcycle. We have a valid Virginia title that is transferable to all 50 states.

This 1986 RG250Γ Walter Wolf example is in very good condition with just 4,836 original miles. The appearance is correct for the year with a red seat and wheel combination. The wheel size is 16” up front and 18” in the rear which was standard for the 1986 model. The only change appears to be a set of aftermarket mufflers and mirrors. The full aerodynamic fairings and exterior as a whole are clean for a motorcycle this age. There are a few light blemishes and a small crack on the right side fairing

The 247cc parallel twin two-stroke starts on the first or second kick and accelerates well with good pickup. Overall this unique and rare sports bike is mechanically sound and ready for its next owner. ***All of our vehicles come with a valid Virginia title, transferable to all 50 states, and a copy of the U.S. Customs release. All vehicles are located in Richmond, VA and shipping can be arranged to your front door.

You will not be disappointed with this motorcycle! We also have a number of spare parts available with this motorcycle.

All of our vehicles come with a valid Virginia title, transferable to all 50 states, and a copy of the U.S. Customs release. All vehicles are located in Richmond, VA and shipping can be arranged to your front door.

This motorcycle was imported LEGALLY! It was NOT imported under a loophole, so there is no chance that it can be seized by the government. It will come with a CLEAN, CLEAR, VALID VA TITLE, and a U.S. Customs Release. **FEDERALLY LEGAL IN ALL 50 STATES**

1986-suzuki-rg250-ww-fairing

There’s more than a week left on the listing, so there’s plenty of time to snap this bike up at that $6,000 Buy It Now price. If you’re looking for a handler, one of the more modern RGV250s is probably a better bet. But for that unadulterated 1980s experience, that seems like a very good price for such a clean machine. In spite of the sellers assurances, I’d check with my local DMV before bidding, but that valid title should make things a bit easier.
