Even Rarer than Rare: 1984 Bimota SB4S for Sale

You’d think that, with just 272 built during its run, the SB4 would be as rare as it gets for a production motorcycle. But no: Bimota actually offered an even rarer version of their Suzuki-powered race-bred machine, the even more limited-production-y SB4S. Just 34 of these thoroughbred machines were factory-built, with another 72 sold in kit form. That’s right: Bimota used to make build-your-own superbikes!

These days, Bimota makes moto-jewelry, high-end fashion accessories that just happen to be incredibly fast motorcycles. But their creations used to be some of the fastest, best handling motorcycles available at any price. Unfortunately, modern manufacturers’ products are not only reliable, but offer handling and refinement Bimota can’t hope to significantly better, considering their limited resources. So modern Bimotas offer an unmatched level of craftsmanship and exclusivity, but minimal performance advantages, compared to the motorcycles that donate their engines and transmissions. But that wasn’t always the case, and bikes like the SB4 are the perfect example of what Bimota did to earn their respected place in motorcycling history.

The rugged, air-cooled Suzuki engine that powered the SB4 displaced 1075cc and came equipped with four valves per cylinder, along with their TSCC or “Twin Swirl Combustion Chamber” technology that improved combustion efficiency. It made plenty of power, so Bimota left it largely stock. Instead, the Bimota’s performance advantage came from improved suspension and much lighter weight: the SB4 shed almost 140lbs off the Suzuki’s 535lb dry weight. The lightweight, one-piece tank and tail is attached by just a few bolts, and can be easily removed for maintenance.

The frame is a masterpiece, and a major contributor to the bike’s improved handling. A hybrid construction of chrome-moly tubing with gorgeous machined aluminum side plates, it’s a shame it’s mostly hidden in the photographs. Wheels were modular 16″ and fitted with radial tires, which were a relative rarity at the time.

So what made the SB4S more exclusive than the regular, pedestrian SB4? Well supposedly we’d be looking at a four-into-one exhaust, although this bike seems to have the regular SB4’s dual exhaust. The S should also have an oil-cooler as well, but it’s hidden behind the fairing in the pictures, if indeed it is present. This machine also features some pretty ugly turn signals fitted to the fairing, which is unfortunate as the stock bike would originally have had none. Not very safe, but much nicer-looking. Given the dual exhaust, I’m not even sure if this is actually an SB4S, so I’d be happy to get any input from any knowledgeable readers. Either way, it’s still a very rare and exclusive Bimota, and bidding is pretty active, with several days left on the auction.

1994 Bimota SB4S, mint condition, very rare and beautiful, pearl paint, Campagnolo wheels, no issues, we at buyer’s expense can ship worldwide.

As always, I’d like a bit more information about this motorcycle in terms of maintenance and history. It’s a bit dusty in the photos, and it’d also inspire more confidence if the seller got the year right: it’s listed as a 1994 model but I’m pretty sure Bimota, in spite of a pretty weird production history, wasn’t still making the SB4 in 1994…  At the end of the day, a mechanical restoration shouldn’t be too hard, as long as the frame, suspension, and bodywork are all intact, since the Bimotas of the era used many components, including the gauges and switchgear, from the donor Suzuki GSX1100.

Hand-Built Italian Style: 1983 Bimota SB4 for Sale

1983 Bimota SB4 R Side

In an era of mass-produced sportbikes, it’s easy to miss the details that made bikes like the Bimota SB4 so special. Virtually every modern manufacturer makes concessions to mass-production, and machines that, at first glance, look gorgeous can get a bit ugly in the details. MV Agusta’s F3 675 is a beautiful sleek, wasp of a motorcycle, but the stock clip-ons are obviously a cost-saving measure… But these early Bimotas, although far from perfect in terms of performance as-delivered, feature an attention to detail that is virtually extinct.

Powered by the durable and tunable 1075 air-cooled Suzuki GSX four-cylinder and five-speed transmission, the SB4 continued Bimota’s tradition of fitting reliable Japanese engines into state-of-the-art frames. That frame was made from chrome-moly tubing with machined aluminum side-plates and helped the bike achieve a svelte dry weight of about 405 lbs. The SB4 rolled on 16″ modular wheels fitted with radial tires, another pair of exotic features on a bike from an era of bias-ply tires.

Groundbreaking Work of Art- ’84 Bimota SB4S Mirage

Location: Huron, Ohio

Mileage: 9,665

Price: Auction, $10,000 starting bid

We’ve seen a run of Bimota’s here recently on RSBFS, many artfully written up by Mike. It’s an interesting company. If you happen to read Bike magazine (from England and one of my favorites) the December issue profiles, among other great stuff, the Bimota company. An interesting read that highlights Bimota’s trouble with the V-Due (see Mike’s post on one here) and how the company started and how it is surviving. What you will learn is that the bikes built early, particularly, were Bimota’s most groundbreaking work. Bimota was ahead of the times, working the power/size equation well before anyone.

Here’s the detail from the seller on this machine-

1984 Bimota Sb4S one of 34 built and sold worldwide. Designed and built by Massimo Tamburini. Tamburini went on to design the Ducati 916 and the MV Agusta F4 and is legendary in the motorcycle industry. This particular bike was built late 1983 In Rimini, Italy and delivered to Performance Works Canoga Park, CA. It comes with the original Certificate of Origin, and Original warranty and service manual serial numbered to the bike documenting its authenticity. This particular bike has been featured on a motorcycle magazine cover and it will also be included also with other period magazines featuring the Sb4S. This bike has several special order factory options; the older style Camponola rims, twin pot Brembo redline racing calipers, ferrari style mirrors, pearl paint- all installed at the factory before delivery. The bike runs well, the tires are decades old and are hard and cracked. Everything works as it should, the petcock weeps a little fuel overnight from the float valve drain tube if left at the on position. The bike needs some TLC as there are some nicks in the paint and minor surface corrosion as would be expected for a bike of this age- but I would rate this bike a 8.5 out of 10. These early Bimotas seldom come up for sale, and some say the SB4S is the best of the space frame bikes. This is a very rare bike, most people have never seen one, it can not be ridden anywhere without drawing a crowd. ( as it should) I’m guessing there are several in the USA, but I’m not sure. This bike is sold as is with no implied or written warranty. It is listed locally, delivery is the responsibility of the buyer, and I will not ship this bike out of the USA. U.S. Bank Transfer preferred, or cash in hand at the time pick up.

And some more pics for you-

Bimota made it’s claim to fame by taking the engines of other bikes (Suzuki, Kawasaki, Ducati) and building a better chassis around it. This bike was built around the air cooled Suzuki GS 1100 motor, starting with some good power. Bimota then went and built everything around it better. And better looking. No doubt that Bimota has built some of the most beautiful bikes on this planet.

This bike appears complete and in pretty good shape for its age. It has some miles (in the world of Bimota’s anyway) but the seller says everything works. Probably will need some new tires. Limited production means you’re probably not gonna see a lot of these in your neighborhood.

So, $10k to start and who knows from there. If you collect, or just love Bimota’s, take a look and read up on this machine. Then go place your bid!
