1988 Honda RC30 in Italy

Honda RC30 for sale

We've seen lots of investor quality, Italian motorcycles from this seller on RSBFS. This is the first Honda he's offered I believe, and the condition looks excellent in the photographs.

Have a good weekend all and looking forward to the comments on this one!

Forbidden Fruit in Cali: 1992 Yamaha TZR250 3XV for Sale

1992 Yamaha TRZ250 R Side2

Fans of lightweight machines that favor handling over outright power hold a special place in their hearts for bikes like this Yamaha TZR250 3XV. Following on the heels of Yamaha's popular RD bikes of the early 80s, the TZR was a road-legal sportbike intended to evoke the company's pure racing motorcycles.

1992 Yamaha TRZ250 Clocks

Like their predecessors, they were lightweight, two-stroke sports machines that were originally powered by liquid-cooled two-stroke parallel-twins, although the 3XV version seen here and introduced in 1991 used a 90° v-twin like the competition from Honda and Suzuki, mated to a six-speed gearbox. The entire package weighed in at under 300lbs dry and featured Yamaha's signature "Deltabox" frame along with a YPVS power valve designed to give the little two-stroke a more usable powerband.

From the original Craigslist post: 1992 Yamaha TZR250 for Sale

I have a 1992 TZR-250 3XV-4 with a wet clutch. This is a R model. I completely restored this bike with new OEM parts. The engine is completely rebuilt, all new transmission bearings, seals, gaskets. Cylinders replated with pistons and crankshaft rebuilt by Roland Cushway. New OEM manifolds and reeds, carbs were also rebuilt, front forks rebuilt and rear shock is a Nitron from the UK. All cables were replaced and brakes rebuilt. Tires are Bridgestone S-20 front and rear. The body work is high quality fiberglass from Japan. The chassis and engine have less than 200 miles on it. I have tons of extras and spare OEM parts. Also front and rear stands. I have over $17,000.00 invested in this bike.

$12,000.00 Firm, No Offers Please.
Serious buyers only.
This is a rare bike. There maybe only 10 of these in the United States

1992 Yamaha TRZ250 Parts

Commenters often express concern about sourcing parts for these two-strokes, but that shouldn't be too much of a problem here: a number of shots are included of the extras and it looks like you should be able to to keep this bike on the road for a long time to come, including clutch plates, rings, gaskets, sprockets, levers, and what looks like a whole case of NGK spark plugs. The bike is in Northern California and does have the road equipment fitted, but the listing doesn't specifically mention whether or not it's actually titled. I'm assuming it does for that $12,000 asking price.

That's a ton of money to part with for a TZR, but this looks like one of the nicest we've seen in a while.

Interim Build – 1990 Ducati 750 Sport

Succeeding the 750 F1, the 750 Sport changed places with the Paso which went on to 904 cc.  Though found on the bargain side of the Ducati showroom, the 750 Sport helped the brand through some negative reaction to the innovative Paso and held the door for the Supersports which followed.

A Weber carbureted desmodue, the 750 Sport gets 75 hp from from the air-cooled 748cc's.  The trellis frame is substantially 750 F1 with extra room under the tank for the larger airbox.  Suspension is Marzocchi front and rear, with Brembo brakes, 280mm fronts and 270mm rear.  Full fairing is a blend of a Paso-ish square headlight nose and F1 seat fairing, but hangs together well.  16-inch wheels are another Paso legacy, but do improve handling.

Looking just great for a member of the quarter-century club, this example hasn't been hidden away with 17,500 miles.  The owner has addressed the major rideability issue of the Weber-equipped 750, by upgrading to Supersport-era Mikuni carbs.  Crucial maintenance items just completed.  From the eBay auction:

Upgrades include Mikuni flat slide carbs, 900SS rear shock and beautiful sounding and rare Conti pipes. Belts and all fluids changed at the beginning of the year as well as the fully rebuilt forks. Tires in very good shape. The bike runs and performs great although a minor carb adjustment is needed.
Comes with the original rear wheel hugger (not pictured), spare turn signal parts, binder with a manual, articles about this model, receipts, etc. and a custom made tri-color cover.

The bike is in outstanding shape except for very few and surface nicks, all pictured:

- on the underbelly of the body panels (normal usage)
- a small crack in the right fairing by the foot area 
- a surface scratch on the tank south of the fuel cap (happened during transport while moving and is currently under the custom cut tank pad) 
- a small touch up in silver done by previous owner
Wheels are flawless. 

I also have an extra full set of fairings and a silver colored (European version) NOS spare fuel tank which can be purchased separately.

20160210 1990 ducati 750 sport left rear wheel

Obviously owned by a fan of the marque, this 750 Sport has been cared for and upgraded.  Though performance isn't that of a newer superbike, overheating and complex valve adjustment aren't there either.  Wear parts are a bargain, and tire availability is actually better now than it was shortly after this bike was introduced.  Classic good looks are helped by a very special factory paint scheme.  If the buyer could talk the owner down from his buy-it-now a little, it'd be just the ticket for a rider who wants to stay out of big-ticket territory and knows just how good a 750 Sport can be...

Round & Round: 1990 Norton F1 rotary in the UK

Rotary powered motorcycles may have been consigned to the dustbin of history but for a while they really were thought of as the future.  Most rotary engined bikes were built as standards or sport touring machines but Norton decided to take their rotary racing and actually achieved a fair amount of success with its F1 series, sponsored by cigarette brand John Player Special.


1990 Norton Rotary F1 (on ebay uk)

Before digging it this particular bike, lets take a moment and review rotary engines.  In a rotary engine all the parts rotate in one direction while standard piston engine designs have the pistons violently changing direction.   A  rotary combustion engine has numerous advantages, including simplicity, smoothness, compactness, high revolutions per minute, and a high power-to-weight ratio.

A YouTube video explained the rotary engine is embedded below. An excellent history of the development of rotary motorcycle engines can also be found here.

Suzuki, Yamaha and numerous smaller manufacturers (including BSA and Norton) all developed rotary powered engines, but Norton was the only one who went the sportbike/racing route.   Norton's racing rotary had a 588cc, air-cooled engine mounted in an aluminium beam frame which resulted in a race-ready weight of 320lbs and an estimated 135hp.  This setup achieved a high level of success for Norton in the TT series on the late 1980's and early 1990's..

NOTE:  The norton engine design resurfuced 10 years later in the truly epic NVR588.

norton 3

Given the success and the high level of interest in the Norton, its no surprise that the company decided to offer a street version known as the F1.  The 1990 Norton F1 was actually based on the Commander model and while it looked like a full on race bike, it was really set up for the street with things like water cooler and street oriented suspension.

Even with the success of its racing rotary, Norton was struggling financially at the time and only about 128 F1 editions were built during the production run.


This particular F1 has only had 1473 miles put on it since new but the seller indicates it will a need full recommissioning so interested buyers should expect costs for fresh rubber and fork oil and possibly a fuel pump and/or brake lines, depending on how it was stored.  Also the seller has only included two photos in the auction which is a bit of a concern.

Is this bike worth the 27,000 GBP asking price (thats about 40k USD)?   Well we have had these on RSBFS a few times before but that was back in 2010 so current value of an Norton F1 is a bit of an unknown.  A search of Bonhams auction history seems to indicate that the asking price for this one is a bit above historical averages but the Bonhams auction bikes had more mileage or were pre-production models.

Overall I think this one is priced a bit high but it certainly meets all the criteria of a true rare sport bike ((numbers produced, technology, condition and location). I think it will definitely appeal to collectors of late 1980's/early 1990's sportbikes, both for its technology and its namesake.

Featured Listing – 2001 Aprilia RSW 250

Update 2.9.2016: Comments are now enabled. -dc

20160207 2001 aprilia rsw250 right shop

Built from 1991-2007 the Aprilia RS 250 is a rare sight, except on RSBFS - but an RSV or RSW - the factory race machines are exponentially more exotic.  Over its long run the model has been ridden to championships by Moto GP stars such as Max Biaggi, Valentino Rossi, Marco Melandri, and Jorge Lorenzo.  A factory test mule, the 2001 RSW 250 offered here has been treated to a lot of factory upgrades, and would make a great start to a race effort.

20160207 2001 aprilia rsw250 left without body

Though power isn't claimed for the 249 cc 90-degree two-stroke twin, it should be around 90 hp  at 12,000 rpm.  Aluminum-framed but with carbon fiber bodywork ( including seat console ), swingarm and wheels, with fuel this bike should weigh less than 300 lbs.  Ohlins and Brembo equipped front and rear.  Expansion chambers are titanium.

20160207 2001 aprilia rsw250 right

20160207 2001 aprilia rsw250 right without body

Brought over from an Italian shop that had done a pristine restoration, this RSW 250 has turned only 200 miles since.  A nice collection of spares is included, including a rare set of carbon-carbon brakes.  The owner attempts list everything in the eBay auction:

  • Complete ATR carbon fibre bodywork including tank, self supporting seat unit
  • Carbon fiber swingarm that an A Kit part typically only available to factory teams
  • Carbon fiber wheels that were designed by Aprilia (and ATR) but manufactured by Ferrari (these wheels are effectively irreplaceable so the bike also has a set of magnesium Marchesinis if you actually want to ride it)
  • Brembo monobloc calipers
  • Ohlins front and rear suspension (and steering damper)
  • Full data acquisition with all sensors active (e.g., suspension travel, EGT, etc)
  • Titanium expansion chambers with DLR end cans
  • Motor has various magnesium A Kit parts (water covers, etc)
  • Motor was built about 200 miles ago with fresh pistons less than 20 miles ago and transmission is completely fresh
  • It is set up to run on VP Q16
  • 520 chain and sprocket conversion to avoid snapping chains (which was a frequent issue with the lightweight racing chain) but lightweight factory chain and sprockets includes along with a small selection of 520 sprockets
  • Carbon fiber battery (but like the wheels effectively irreplaceable so aluminum version also included)
  • Battery charger included
  • Spare titanium expansion chambers (not really spare but if you know anything about these bikes you already know that there were a litany of expansion chamber types that could be used to vary the power delivery)
  • Spare pistons and gaskets

Whether you were an up-and-coming rider or a skilled club racer, finding a bike like this could make a career.  Appearing ready to load in the trailer and head south, this RSW 250 looks prepared for competition and has adequate spares to at least get rolling.  Details and contact information can be found on the eBay auction or at the Racing Bikes For Sale facebook page.

The owner also has a 2002 RS 250 Cup available with significant spares available, which could also be a less exotic but exciting alternative.  See the eBay auction or Racing Bikes For Sale page.
