In the second production year of the Tesi, the 851 engine was revised. A new crankshaft with an additional 4 mm stroke and modified pistons increased the displacement of the Desmo four-valve engine to 904 cc, producing 113 hp. In 1991, both Tesi 1D models were produced in parallel, but only 20 units of the 904 cc variant were built, as it otherwise remained identical to the 851 model.
From 1992 onward, the Tesi 1D SR was offered exclusively with the more powerful engine. Visually, the SR could be recognized by a new white/red paint scheme with three green accents on the fender, tank, and tail section. The shape of the fairing and monocoque remained unchanged. Additionally, large Bimota logos were applied to the sides of the fairing, and the „Tesi 1D“ lettering on the tail featured a small „SR“ inside the „D.“
The composite chassis, consisting of two lateral aluminum frame plates, aluminum swingarms at the front and rear, and a steel tubular subframe made of chrome-molybdenum tubes – supporting the rear shock absorber and seat at the back, and the fuel tank and steering head at the front – remained unchanged. As with the 851 models, a central Marzocchi rear shock absorber was used, along with a Brembo braking system featuring four-piston calipers and floating 320 mm dual front discs, as well as a two-piston fixed caliper with a 230 mm disc at the rear. The wheels measured 120/70 ZR 17 on a 3.5″ rim at the front and 180/55 ZR 17 on a 5.5″ rim at the rear, both mounted on aluminum Marchesini wheels.
Technical modifications included new bearings in the hub-center steering, addressing some issues found in early models, and replacing the front, side-mounted Marzocchi shock absorber with a more responsive Öhlins unit.
The German magazine Motorrad tested the Tesi in 1991 and even competed in a round of the „Battle of the Twins“ racing series with the road-legal production model. The riding impression was described in issue 19/1991:
„The chassis impresses with its high steering precision and accuracy. However, its greatest advantage is in braking zones. When the front wheels of competitors start to chatter, the Bimota remains absolutely stable and steadily closes in on the lightweight frontrunners.“
The German magazine PS also praised the front suspension in its test (issue 01/1991):
„Bumps seem nonexistent in Misano—at least, the hub-center suspension doesn’t let any be felt. Braking quickly becomes a joy. The Bimota barely dives and remains extremely stable. There is a lot of reserve here—certainly far more than with a telescopic fork, which hardly compresses under braking.“
