Trophy Bike: 1986 Honda GB400

The cafe racer craze makes an appearance on a regular, cyclical basis. From the original cafe bikes "doing the ton" through sanctioned TT events such as the Isle of Man, the cafe racer evokes a rebel streak with a distinctly English flair. Sporting, brash, forward and yet somehow very basic, the cafe racer stirs your inner Mike Hailwood to life. And while authentic cafe racers are custom affairs, manufacturers such as Norton, Triumph, Royal Enfield, BSA and Vincent have all had a hand in producing models in this image. Honda, too, tried their hand at the cafe scene. The result was the "GB" series of Tourist Trophy-inspired bikes, including today's rare GB400.

Rare 1986 Honda GB400 for sale on eBay

The Honda GB was born from humble beginnings. Utilizing a necked-down XL600 thumper motor, the GB was made available in both 400cc and 500cc configurations. The stone-simple and reliable air-cooled single was augmented by a a solo seat (a dual-seat model was available), a TT-style fairing, and clip-on bars. Wire wheels and a requisite megaphone-style muffler gives it some element of English authenticity. Those sidecovers? Made of metal, just like back in the day. Technology intervened in the manner of electric start (a kickstarter is attached to be period correct) and a single disk brake up front. The rest is basic but effective. Like the SRX models from Yamaha, the GB was a throwback to the past, a nod to lightness and simplicity and a relative failure.

From the seller:
It took me forever to find one of these and due to something coming up I have to sell it. I'd planned to keep it for the rest of my life so this is truly a regretful sale.

I bought it with 5600km. It currently has less than 11,000km. I have meticulously looked after it. This is the work I've done to it:

Three oil and filter changes up to now. It is important to change the oil on these often.
New front and rear brakes
Cleaned carburetor
New Bridgestone Battlax BT45 tyres put on at 6000km - great tyres in the rain
Installed gold DID525 X-ring Chain and aftermarket rear sprocket at 6000km
the guy at the shop said the front sprocket was good enough to not need changing.
Aftermarket foot pegs (still have the original pegs that you can have)
Shaken valid until 2019 (only important if you are buying in Japan)

I also have an extra carburetor kit that can come with it if you ever need to clean the carb further down the line.

More from the seller:
I never use the electric start but it works fine. This is my daily driver, it kick starts every morning literally on the first kick, every time. Exceptionally reliable. It's really light, really forgiving, and fantastic for Japanese roads.

Never dropped, crashed or anything like that.

I think it had been sitting for a long time before I picked it up. There is some pitting on the engine block, handlebars and some faded paint behind the rocket cowl. Cosmetically I would say it is about 7/10.

Mechanically, it's a excellent. I don't know how to polish metal but I've always kept it clean. I have always parked it with a cover everyday and overnight. It also comes with the factory installed centre stand.

I have seen some online sell overseas for a lot more. These are rare and the value will only increase over time, especially ones like this with such low miles.

Available in Japan and export markets from 1985 - 1990 (and the US as a 500cc model in 1988-1990), the GB is a relatively rare machine. Sales were stronger in home markets and European pockets, but the US turned up its collective nose at this faux Brit bike. Today these are coveted machines for what they represent. This particular 400cc example was never seen in the US, and today resides in Japan where it was born. Check it out here if you are hankering for a reliable throwback - grab your pudding bowl and goggles and try for the ton. Good Luck!!

Track-only Buzzsaw: 2009 Aprilia RS125

Built and sold for the street in just about every other country, the 2009 Aprilia RS125 came to this country as a track-only weapon, thanks to its two-stroke mill's inability to pass EPA muster. That didn't stop more than a few track rats from ponying up the $5,500 MSRP for one of these GP grid-derived featherweights.

2009 Aprilia RS125 for sale on eBay

Plenty of these little monsters have found their way to road legal status, though it is unclear whether the bike here carries a street title.

Surprisingly spacious for a 280-pound sportbike, the RS125 found an audience with new racers and track-day beginners who needed to learn to change direction quickly without muscling over a bigger machine. Handling was always the little machine's forte, aided by its weight and suspension and brakes that outstripped its price point.

With no torque and a powerband that doesn't get tuned up until 10,000 rpm or so, the 30-ish horsepower Aprilia rewards momentum, and the guts to stay off the radially-mounted single-disc front brake.

The bike shown here has covered fewer than 2,000 miles, and has been upgraded to a Shorai lithium-ion battery and will be sold with a fresh set of tires.

From the short original eBay listing:

Bike is in excellent condition everything works,tires are in great shape also comes with a new set. Battery has been replaced with a Shoria lithium battery.bike is ready to ride.

The auction concludes on Friday, and reserve has yet to be met at just over $3,000. For a non-street-legal bike that only cost $5,500 new, that's getting on for a steep ask. Let us know what you think in the comments below.

The Joy of SRX: 1987 Yamaha SRX250

Today we find a fun rare model that is - for once on RSBFS - totally affordable. The Yamaha SRX series included multiple displacements, although in the US we only received the XT-derived 250cc model and the XT-based 250cc machine. Home markets also included a 400cc variant. Based around a nimble, single cylinder air-cooled engine, the SRX models were extremely narrow and light, focusing on nimble handling and flick-ability rather than oodles of HP and straight line speed. The design was neo-British old school, and the overall package was unique and usable. Unfortunately for Yamaha, these were not great sellers, and the US models were limited to only a few editions over the 12-year global run. The 250 suffered the worst fate; a single year availability in the US over a 2-year model span. Then it was gone like it was never there at all....

1987 Yamaha SRX250 for sale on eBay

From the seller:
Up for sale is my 1987 Yamaha SRX250. This bike is super rare and only imported the the US for one year. The motorcycle is super clean for being 30 years old. The bike is all stock and runs, drives, stops and idles very well. It has 10,708 miles. The bike is missing the side mirrors. The engine is 249cc with a 6 speed transmission. The engine shares many parts with the Yamaha XT250 enduro which was produced for many years. The tires will need replacing at some point. Inside of the fuel tank is pristine. The bike has a brand new battery. All controls work as they should, turn signals, horn, kill switch, ect....

I have yet to see another one on the road. The bike gets comments everywhere it goes. The bike is a blast to ride and has plenty of power.

The antithesis of the Ninja 250R and as far away from the Honda 250 Rebel as it could get, the SRX250 looked to have carved out its own niche. But the 1980s were not about small displacement bikes, and although attractive and utterly practical, the smallest SRX lost out to lack of interest. It was a practical bike that held the promise of a lot of fun (as much fun as 17 HP will get you), but small displacement and wild introductions of Hurricanes, Ninjas, Turbos and GSX-Rs ultimately buried that fun in a sea of noisy performance.

Today the SRX is a loved model (the 600 version much more so, since we are all capacity bigots). Honda has come closest to recreating the magic with the CBR250, and with a different era upon us is actually moving a fair number of units. The little CBR will never reach the rarity or novelty of the SRX250, but then again a marketing failure is an expensive way to create a future rare model. Check it out here. Sure it's more of a toy than a true canyon tool for many - but it's very rare, very cool, and very, very affordable. What's not to like?

Lightweight Single: Pristine 1990 Gilera Saturno Bialbero for Sale

1990-gilera-saturno-r-side-front

Looking very 80s, the Gilera Saturno Bialbero  could be mistaken for some sort of custom Ducati. But Gilera, of course, should be held in the highest regard by fans of this site, as they were the first company to slot an inline four into a frame transversely, solving in one fell swoop the difficult cooling issues that previously faced four-cylinder motorcycles. This bike has just one cylinder like the original Saturno and embodies the company’s racing ethos, stressing light-weight and handling.

In the 80s, Gilera was mostly producing a line of offroad-biased singles with a 350cc capacity that were obviously a far cry from their road-racing bikes of the 1950s. At the urging of a Japanese marketing company, they developed a retro-styled sportbike, and that updated Saturno sparked some minor interest worldwide.

1990-gilera-saturno-l-side

In most markets, the Nuovo Saturno was motivated by a liquid-cooled, 491cc version of the company’s four-valve, dual-overhead cam single, although a smaller 350 was available in Japan. In fact, the “Bialbero” designation helps to differentiate the bike from the earlier Saturno and refers to the number of camshafts: two. That engine put out a seemingly unimpressive 44hp, but the complete trellis-framed machine weighted in at a claimed 302lbs dry. That’s 250cc two-stroke territory, with the same claimed peak output and a much broader powerband. Suspension was simple but modern, with 17” Marvic wheels front and rear and a set of Brembo brakes to slow things down. The ‘box has just five speeds, owing to the package’s off-road roots, but the torquey engine should make any gaps easy to ride around.

1990-gilera-saturno-clocks

With just 72 miles on the clock, this may be the lowest-mileage Saturno on the planet, and you may be waiting a long time for an example this nice, regardless of miles: these very rarely come up for sale, as Gilera collectors aren't flavor-of-the-week types. It helps that the Nuovo Saturno was intended for collectors in Japan, and only a few made it to other countries: in 1990, just 50 were imported to the UK.  However, in spite of their rarity, they don't sell for huge money, making them a reasonable proposition for regular folks who want something out-of-the-ordinary.

From the original eBay listing: 1990 Gilera Saturno Bialbero for Sale

I kept this rare machine in Germany for years before I was able to legally import it this year. I don't know of another one ever available in the United States. And this one can be registered and ridden. It is in out of the crate perfect condition.

Imported earlier this year from Germany. Comes with original German registration and U.S. Customs and Border Protection entry form (Form 7501).

The Gilera Saturno Bialbero 500 is a motorcycle road made the motorcycle manufacturer Gilera and marketed between 1987 and 1991.

1990-gilera-saturno-engine-detail

Bidding is just north of $3,659.00 with plenty of time left on the auction, if you're looking for something rare, affordable, and very fun: these are extremely nimble bikes that would make perfectly lightweight track or racing machines. If you're handy with a wrench, there's another, much less pristine 1988 Saturno for sale on eBay right now that'd make a pretty perfect foundation for racebike to compete in something like AHRMA's "Sound of Singles" class, but this one's simply way too nice to abuse.

You Haul – 2006 Aprilia RS 125

Aprilia buried their competition with the 2006 update of the RS125.  With specifications and looking like a much larger supersport, it was the beginner's dream machine.

With the visual template of their 1000cc machine, the 125cc two-stroke single doesn't disappoint with 28 hp.  A factory power kit was available for the racetrack.  The powertrain is brought into the modern age with water cooling, oil metering, and a 28mm Dell'Orto carburettor.  The chassis has been Aprilia's perennial claim to fame, the 2006 alloy twin-spar weighs just 21.5 lbs., and has matching banana swingarm.  Though a single front brake is all that's required,  it's a 320mm disk with 4-piston radially-mounted caliper, along with a 220mm rear.  The full fairing carries dual halogen headlights and Aprilia's digital-plus-tach dash.

Boasting California title and just 520 miles, this RS125 looks showroom ( maybe a showroom in Europe or Asia ) in the just enough to make you want more pictures.  I'm not a tail-tidy fan, but this bike calls for it - nice to have the stock parts, though.  The owner has completed the best part of the power kit with an Arrow exhaust and has these comments in the eBay auction:

With rave reviews, the RS125 did well even priced 1/3 higher than the market at the time.  The buy-it-now is up there as well, though a great value for the rarity and condition.  The accommodations and performance will likely surprise all riders happily, S-M-L if not XL...

Lightweight Italian: 1991 Gilera Saturno 350

1991 Gilera Saturno 350 R Side

Although forgotten now, Gilera was one a famous manufacturer of serious racing hardware, and this "Nuovo" Saturno was an attempt to revitalize the marque in the late 1980's. Now owed by Piaggio, Gilera was originally founded in 1909 and had a long history of high-performance motorcycles.

1991 Gilera Saturno 350 L Side Rear

These sportbikes were often based around big singles, sort of like an Italian Norton Manx, although they were also famous for circumventing the significant cooling issues that surrounded multi-cylinder engines by producing a transverse four-cylinder that dominated 500cc GP racing through the 1950s.

1991 Gilera Saturno 350 R Side Fairing

The reborn Saturno was powered by a big, liquid-cooled four-valve single that put power through a five speed gearbox. Most markets got a 491cc engine, although a smaller 350 was available for Japanese customers. This simple, robust powerplant was suspended in a lightweight trellis frame with modern suspension and brakes front and rear, with lightweight Marvic wheels that provided an all-in weight of under 300lbs dry.

1991 Gilera Saturno 350 Dash

From the original eBay listing: 1991 Gilera Saturno 350 for Sale

In the mid 80s Gilera collaborated with a Japanese company, C. Itoh & Co. Itoh produced a frame design and Gilera the powerplant. The frame was very similar to that of Ikuzawa. Gilera put the project in the hands of a gentleman called Sandro Columbo, who in the 1950s had been in charge of their race team.In August 1987 the bike was ready as a prototype and in March 1988 started the production. Two versions were built: a 350cc model only for the Japanese market and sold by Itoh, and a 500cc model for the rest of the world, sold through the Gilera network. The bike was by all accounts very expensive in its day and few were sold.

This is a 1991 example, which has travelled just over 5,100km or 3,100 miles and been very well cared for, and lightly modified with nice chrome high pipes and a bikini tail section. An rare opportunity not to be missed.

1991 Gilera Saturno 350 Engine

Very rare in any form, the Saturno is all about light weight and handling, with a look that, to me, is very purposeful and doesn't appear "styled" at all. As the seller mentions, the dual exhaust on this one isn't stock as they generally use a single exhaust on the right side of the bike, but it looks to be of high quality and does suit the bike.

1991 Gilera Saturno 350 R Side Tail

This bike is currently located in New Zealand, although the seller claims they also have a location in Texas. If you happen to live in New Zealand, or are able to register it in your state here in the US, this would make a great back-road bike. If not, this might make a very
