In 1995, Bimota introduced the YB11 Superleggera as the successor to the YB8 and YB10, continuing their frame concept with slight modifications. With a dry weight of 183 kg, the Superleggera (Italian for „super light“) is 2 kg lighter than the YB8, despite featuring a massive 51 mm telescopic fork. Compared to the Yamaha YZF-R 1000 Thunderace, which provides its engine, the YB11 is an impressive 25 kg lighter.
The Thunderace engine is based on its predecessor, the FZR 1000 Exup, but has been tuned for higher torque in the lower and mid-range. It produces 147 hp at 10,250 rpm and 108 Nm at 8,500 rpm.
The YB11 showcases the art of precision machining, particularly in the swingarm mounts, footpeg brackets, and brake master cylinder mounts. It also features a carbon fiber front fender and a 51 mm Paioli fork with carbon fiber tubes.
The newly designed monocoque is more dynamic in shape and continues to serve as the fuel tank, seat, and tail fairing, supported by a bolted-on rear subframe. The YB11 is offered exclusively as a two-seater, though the passenger seat is covered by a well-integrated fairing, giving the Superleggera the appearance of a monoposto.
The braking system, sourced from Brembo’s Gold Series, consists of dual floating 320 mm front discs with four-piston calipers and a 230 mm rear disc with a two-piston caliper.
The three-double-spoke Antera wheels are fitted with 120/70 ZR 17 tires at the front and 180/55 ZR 17 at the rear. The Paioli fork offers adjustable rebound and compression damping, while the Paioli rear shock absorber features an adjustable preload, rebound, and compression damping. An Öhlins rear shock was also available as an option.
In addition to 600 models painted in red, white, and black, Bimota produced 50 special editions in 1998 with a new blue and silver color scheme to celebrate the brand’s 25th anniversary as the „Anniversary Edition“. In the 2000 model year, another limited version was released as the „Edizione Speziale“.
