Design
[edit]The KTM 990 Super Duke has a naked body style and was designed by Gerald Kiska at the Kiska design studio in September 2003.[1][2] It is built around a chromium-molybdenum trellis frame with powder-coated aluminum sub-frame and KTM LC8 engine used in several other KTM motorcycles. The engine in the KTM 990 Super Duke is a DOHC 999.8cc 75° V-twin with four valves per cylinder. The liquid cooled engine has an 11.5:1 compression ratio and uses dry sump lubrication with two rotor pumps. It has a six speed gearbox and a wet multi-plate clutch, and chain final drive.
Suspension is made by WP. In 1995, KTM Motorradholding GmbH acquired Swedish motorcycle maker Husaberg AB and took control of the Dutch company White Power Suspension). It consists out of a 48 mm upside down fork with 24° rake at the front and a WP fully adjustable shock absorber with a 4”/103 mm trail at the rear. Brakes are twin 320 mm discs with 4 piston calipers at the front and a single 240 mm disc with a single piston caliper at the rear. They are made by Brembo.
The bike has a 56.6”/1,438 mm wheelbase.
Facelifts and KTM 990 Super Duke R
[edit]2007 update
[edit]In 2007 the KTM 990 Super Duke was updated. The new model received a slight reduction of the steering head angle to 66.1° (previously 66.5°). Changes to the electronic fuel injection system were made to improve throttle response, smooth out the power delivery, and meet emissions standards. Another result of this were improved fuel economy and thus improved range. To further increase range the fuel tank's capacity was increased from 15 liters to 18.5 liters.
The front brakes were updated from axial mounted brake calipers to radial mounted brake calipers.
Along mechanical updates the 2007 model received an updated dashboard, headlight, headlight fairings, tank fairings and tank shape.
