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: 2Moto 2M400R-SP

If you are thinking that you haven’t heard of the 2Moto 2M400R-SP, you are probably correct. But I’m sure you have heard of Yamaha’s wildly successful two-stroke, the TZR-250. And knowing RSBFS readers, you probably wished for something like that – but with more horsepower – for your street ride. I mean, imagine the wild hi-jinks you could pull off with that kind of hardware but twice the power. Well, wish no longer. Think of the 2M400R-SP as a top spec TZR, but with 400cc and 85 horsepower at the rear wheel. At 265 pounds, this hybrid weighs less than the 250 it is based off of, but is considerably more potent. At the end of the day this is less TZR-250, and more like what Yamaha could have done with the RZ350 had that lineup continued. We don’t often feature custom builds on these pages, but read on – because this one is worth it.

2Moto 2M400R-SP2004 for sale!

UK-based 2Moto is a bike builder that concentrates on just a few offerings. Most of their business is in the form of YZR500 and NSR500 GP500 replica race bikes. By tame comparison, the 2M400R is their street model – and what model it is! Start with 1990 TZR-250 chassis – this is the 3MA model offering, selected because it best fits the venerable parallel twin RZ motor. It is also widely known as precise and forgiving in terms of handling. Graft onto that a single-sided swing arm from the Honda RVF-400. The RZ style motor is a good choice as there is a solid foundation of knowledge and parts available; after all, these are the same basic engines utilized in off road quads. The power requirements of a quad screaming up a dune is quite a bit different than a racer / street bike, but by careful component selection, porting and assembly, a seriously stout smoker is born. Consider the dry clutch, the electric water pump and the clever custom carbon fiber sprocket cover that incorporates support for the gear selector shaft. Front forks are 600cc Supersport items, if that gives you any indication of the braking and cornering forces expected. Wrap that whole package in 125cc GP bodywork (yes, you heard that right – 125cc), and you end up with the spiritual successor to the RZ, and a phenomenal machine in its own right. This is a level of detail you would expect from larger firms such as Bimota, and the outcome is glorious.

From the seller:
Since the Aprilia RS-250, no new 2-stroke bikes have been built by any manufacturers. We thought it was about time to rectify that situation. And we like the RD-350 YPVS engine as there are lots of relatively inexpensive engine upgrade option courtesy of our American cousins who insist on racing some crazy Yamaha Banshee quads, some making in excess of 150 horsepower!

Having built plenty of specials over the years, we had a pretty good idea what would work. And, what doesn’t. The YPVS engine is fairly long, so most of the 250cc type V-twin chassis are too short, as we know from experience. In the end, the Yamaha TZR-250 3MA chassis fit the bill perfectly. Plus, the same chassis is used in the TZR-125 and the SZR-660, so availability is reasonable. And, we knew the engine would fit with only a few modifications to the chassis.

This highly desirable example of a modern 2-stroke sportsbike can be ridden on the street. A few of main specs are:
-400cc YPVS engine
-85 hp at the rear wheel
-120kg wet weight, no fuel
-K-Tech suspension
-The bike is titled as a TZR-250, 1990 model year and fully road legal in the UK.

Price: $12,500

Interested buyers should contact Felix Hirzel of Team 2Moto: info@2moto.co.uk

This custom build is not a simple one-off by someone in their backyard. This is a complete bike offered by a noted chassis and speed parts manufacturer. This is a repeatable process thanks to engineering, testing and experience. This is, as the ads say, professional grade. And if this 400cc doesn’t light your fire, perhaps you should check out their other offerings such as GP replicas of either the YZR500 or NSR500, race-ready Moto2 chassis, or a 250-sized GP racer stuffed full of Kawasaki 650cc twin power. Like Bimota, frame kits are on offer as well in the event you want to build your own. But what could be better than a professionally crafted, street-going two stroke like this 2M400R-SP? It is ready to go, no assembly required. Serious parties can send an inquiry directly to 2Moto’s Felix Hirzel, and talk numbers. Drool over the pictures on this one. Take your time. This bike has details you don’t want to miss. And if you miss riding a serious two stroke on the road, consult with your wife, consult with your banker, and consult with your local laws. Then make the call and make us all jealous. Good luck!!

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: 1994 Honda NSR250R MC28 for Sale

Update 10.26.2019: This bike has SOLD! Congratulations to buyer and seller! -dc

If you’re a fan of four-stroke motorcycles, two-strokes like this Featured Listing Honda NSR250R MC28 can be a little… underwhelming, the first time you see, and especially hear one. I mean, even with aftermarket pipes, they make an oddly weedy sort of zing as they rev, and generally sound like you’ve strapped a couple of leaf-blowers with fueling issues to your bike. But fans know that’s the sound of a pure, simple, and utterly focused bike that emphasizes handling over brute power. And the MC28 was probably the most sophisticated of the breed and, until recently, very hard to get a hold of here in the USA.

The mechanics of a two-stroke are inherently primitive, and not very eco-friendly, since lubricant is mixed with the air and fuel in a constant-loss system that will spew heavy, oil-rich smoke from the tiny exhaust cans. But that simplicity means a two-stroke engine is incredibly light weight, and makes pretty spectacular power for a given displacement. If you come from a four-stroke mentality, a 250cc sportbike sounds very unimpressive, but bikes in the class weighed in at around 300lbs and could make as much as 55hp at the wheel when properly tuned, or even a bit more if you didn’t mind the occasional engine seizure…

The original NSR250R MC16 was introduced in 1987 and laid down the pattern the others would follow, with a 249cc 90° v-twin that featured an RC powervalve, and PGM electronic ignition, and a six-speed gearbox, wrapped by an aluminum beam frame. The final MC28 version of the bike seen here debuted in 1993 and added a slick ELF-designed Pro-Arm single-sided swingarm and trick PGM-IV electronic ignition system to the mix, making it one of the most advanced sportbikes of any displacement available at the time.

Today’s example has incredibly low miles and has had the wheels painted white to match the bodywork for an extra dash of 90s style. It’s currently located in British Columbia, but shouldn’t be too hard to register here in the US, depending on where you live. California residents, as always, should visit their local DMV with a sack of unmarked, non-sequential bills and a bottle of good scotch…

From the Seller: 1994 Honda NSR250R MC28 for Sale

Up for sale is a beautiful 1994 Honda NSR250R MC28 with only 1,000km  (622 miles). Bike is almost in mint condition. It had a stress crack on the right upper cowling around the blinker that has been professionally repaired. You can see the repair from the inside of the fairing but the outside looks perfect. All fairings are genuine Honda 100%. Bike is completely stock, like it was on the Japanese dealership floor in 1994. No dents on the tank (the tank itself was professionally cleaned and rust-proofed in 2018), one tiny chip in the paint. Wheels were professionally refurbished in 2018 and converted from red to white, which as a personal preference, was a game changer for how the bike looks. A brand new OEM rubber chain guide is included in the sale. Only a few handling marks not worth mentioning. Bike looks awesome. Just serviced with new fork seals (2017), new battery (2018), new engine fluids (2019), and Dunlop Sportmax Q-14’s installed front and rear in 2017. Runs like the day it was new.

This NSR was purchased from a dealer in USA in 2017 and can easily be returned to the USA market. I’m happy to deliver this bike to Blaine, WA 98230 to provide an easy loading point for any USA-based buyer. Bike is currently titled as a streetbike for road use in BC, and had similar title in USA. Thank You For Looking. Call 250-588-8775 for more photos or questions.

Price: $12,500

Well, the completely stock condition might mean you’re stuck with Japan’s government-mandated 45hp, but the MC28 version is much harder to de-restrict than earlier versions and originally required a hard-to-obtain HRC ignition card to unleash the full power. For collectors, it means that the stock electronics and wiring harness haven’t been monkeyed with, and 45hp is still plenty of fun in a 300lb package, if the new owner plans to ride it. Aside from the minor fairing damage the seller describes and the non-original paint on the wheels, this thing should be immaculate, given the mileage.

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.

Purity of Purpose: 1998 Yamaha TZ250 for Sale

Laypeople often love cars and motorcycles with gratuitous stylistic frippery: air vents leading to nowhere, extraneous “engine beautification” panels to cover up the oily bits and wiring, unnecessary surface details to break up large panels. They don’t really understand the function of all those parts, or aerodynamic styling, so if it looks right, it is right. Purists also appreciate design, but often feel that good looks are a direct result of function, that that beauty is the natural result of effective engineering. Failing that, at least functional design has an aesthetic appeal all its own. Simplicity and lightness are especially important for racers, and sometimes the shapes that result look odd until you understand why they developed the way they did. In other cases, a pursuit of purity of purpose results in shape that just looks so right, like this Yamaha TZ250.

The TZ250 wasn’t simply a TZR250 with race plastics and the lights removed. It was  a pure racing machine, something privateers could buy directly from Yamaha and use to compete in Grand Prix racing. Everything on the bike is designed to help the bike make power, cheat the wind, or simplify servicing. Every component is as light as possible, and these featherweight machines are the model of elegant simplicity. Early versions were powered by a parallel-twin engine, but Yamaha switched to a v-twin in 1991, a liquid-cooled unit was basically one-half of the YZR500’s V4 and included a counterbalancer that made the engine much smoother, backed by a cassette gearbox for fast gearing changes trackside to maximize the bike’s narrow powerband.

The package was updated significantly in 1992, with subsequent changes amounting to a gradual evolution, refining and tweaking the package. The engine was updated in 1997 to allow the bike to run on unleaded fuel, as required by FIM regulations, while the 1998 version seen here introduced a sealed airbox with ram-air and oval-slide carburetors, along with revised bodywork that included the famous tapered tail.

From the original eBay listing: 1998 Yamaha TZ250 for Sale

I have a very, very nice 1998 Yamaha TZ250 4TW available. I purchased this bike in 2015 from a Southern California racer. It had been raced recently. I have done absolutely nothing to the bike, so it is still in as-raced condition. Overall its in excellent shape. The tank is flawless save for a very small dimple (about 1/8″ across). The bodywork is very good, but has a few imperfections here and there such as chips and scuffs. Normal racetrack wear. It has been stored in a heated storage facility with very low humidity here in Montana.

It has 190 miles on the top end and MCE racing crank. 2003 bodywork and airbox conversion. Includes PitBull rear stand, but no spares.

You can send your shipper here to my home in Red Lodge, Montana or I can deliver to one of several freight forwarders in Billings, Montana for attachment to a pallet.

The $14,500 Buy It Now the seller is asking for this TZ250 is a pretty good price, from what I’ve seen. It unfortunately doesn’t include any spares, which presents a headache if you’d like to use it regularly for race or trackday riding. You’ll obviously want to go through it thoroughly before using it, as it has been sitting for a couple years, but these are designed to be easily torn down and rebuilt, with crankshaft removal possible with the engine still in the frame and gearing changes to the cassette box taking only a half hour or so. Many TZs are being actively raced in AHRMA and other series, so I believe obtaining parts to keep them running isn’t prohibitively expensive, but these are a dying breed and represent the end of an era.

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: 2002 Aprilia RS250 Diablo Nero MK2

RSBFS friend Gary from Utah is back, and take a look at what he pulled out of his toy box this time: a titled and registered Aprilia RS250 Diablo Nero with low miles and lots of shine. In typical Gary fashion there are a lot of high-quality photographs to drool over, and although this bike looks great in his space, imaging what it might look like in your garage. Or man cave. Or living room. Dare to dream.

Featured Listing: 2002 Aprilia RS250 Diablo Nero MK2

The Diablo Nero in the name simply refers to the paint scheme – Black Devil in English. Although initially released in 1995, the RS250 went through a significant revision in 1998. These later bikes are referred to as Mark II machines, and sport updated bodywork (aerodynamic improvements), new adjustable Showa front forks, ride height adjustment at the rear, and wider wheels/tires. The basic chassis configuration and Suzuki-derived engine had previously proven their merit, and carry over unchanged. One of the biggest changes was the adoption of digital capabilities/instrumentation in the cockpit; the on-board computer no longer relied upon a speedometer cable, and an on-board lap timer was included. According to sources, Aprilia offered multiple different paint schemes on the Mark II series bikes, averaging about 2 per model year (including many race replica editions: Reggiani, Biaggi, Rossi, Melandri, Harada). By 2003 the party was officially over, although some European countries sold off ’03 bikes as ’04 models due to the date of registration.

From the seller:
This RS250 has 5,480 miles on it. Minty condition. No crack, no scratches no dents. Looks like a million bucks! Completely stock except for the upgraded adjustable rear sets. Two original keys, 17 digit vin number. Runs like new and will come with new fluids and carb service. Utah titled as a street bike for road use.

Price: $12,500 or best offer
Contact: rmurangemasters@aol.com (Gary)

Aprilia laid claim to producing the closest replica of a race bike for the street. And this was no joke; road going RS250s differed surprisingly little from the original racers, excepting concessions required for convenience and safety. These are very capable and very coveted motorcycles, good for 72+ HP in stock trim, and tipping the scales at a scandalous 300 and change pounds. These are potent rocket ships for those who A) can fit on board, and B) can keep the revs above 9 grand. Meet those minimum requirements and life will buzz by in a blur of madness.

This bike is made available by a collector who is well-known to RSBFS readers. We have lusted after his amazing collection of small and large bore homologation machines, and his penchant for storing them indoors, on the carpet, inside his house. We are told he is responsive to inquiries, and those who have purchased reported the bikes were in as-promised condition. Check out all of the photos here, and then try to convince yourself you don’t want a titled two stroke at the pinnacle of what the quarter-liter smokers had to offer. Once you’re done arguing with yourself, give Gary a holler and strike up a deal. Good Luck!!
