Back on eBay with some new pictures after last year's - RSBFS post - and auction which did not meet the reserve - Donn
Massimo Tamburrini was still at Bimota when the ground-pounding SB4S was introduced, using the 1,075cc Katana air/oil-cooled engine. Though power is similar between the Suzuki GSX-1100S and the SB4S at around 112hp, Bimota holds a clear advantage in weight and top speed. The northwest-based SB4S has recent maintenance and no apparent damage.
Bimota's artwork begins with the complex trellis frame, continues to the milled side connectors, and is covered by the full fairing and flowing tank/seat console. With the tuner's airbox and 4-into-2 exhaust, the overhead cams for Suzuki's big four hulk behind the bodywork. Classic Ceriani right-side-up forks and DeCarbon monoshock are adjustable and support 16" Campagnolo wheels. Not expected to be all that light as an unlimited GT, the SB4S is still 75 lbs. lighter than the Katana, and long gearing allows a top speed increase to 155 or so.
This SB4S's kmh odometer translates to just under 10,000 miles, and provided the recent service included carburetor cleaning, appears to need nothing more than a spa day, and tires. The pearl white fairings with red graphics look undamaged, and the rest looks complete and original. From the eBay auction:
1984 Bimota SB4S. Very rare full fairing, tube frame, one of 106 ever made, beautiful white pearl paint, new battery recent tune up and fluid change, bike runs perfect, no issues. This is a pristine example of a early tube frame Bimota. It’s a jewel.
At this stage in Bimota's life the SB4 was also available as a kit, with the buyer supplying a GSX1100S for parts. Seeing a home-built SB4 might be just as rare, but the factory-built SB4S is one of just a couple of hundred, rarer still with full fairing. Not to mention cherry pearlescent paint. The 16-inchers lend a funny look to the SB4S, but the fairing is roomy and can take the rider as far ( or farther ) than common sense allows...
