990 SUPERDUKE (SERIES MODEL):

Lighter, more agile and aggressive than everything else being on two wheels ever before. The KTM 990 Superduke is not less than a radical advance in building motorcycles and a redefinition of the category “naked bike”. The 990 Superduke is a motorcycle without compromise, defined through extremely agile handling, innovative technology and an independent, brand-characteristic design.

As the first manufacturer of motorcycles KTM launches a large-displacement 2-cylinder Supermoto. Therewith KTM demonstrates again its leading position in the Supermoto segment and points up the theme leadership for the brand.

990 RC8 (DEVELOPMENT LEVEL P1):

For the RC8, we brought our riders to the design table as well as the best technicians and designers. Our aim: The ultimate weapon for am-bitious street-fighters. That means: A radical concentration of its mass around the compact 75° V2. Innovative details are everywhere: The seat is the tank, keeping fuel at the machine’s centre of gravity. Dry sump lubrication allows the entire exhaust system to sit precisely where it has the least influence on dynamics. Directly under the engine. The fairing is designed to produce: The least possible crosswind drag. The result: No crosswind oscillation, spell-binding agility, and aggres-sive steering ability.
(Planned start of production 2007)
