Overview

Introducing the 2008 KTM 990 Super Duke: a brilliant fusion of raw power, precision engineering, and unmistakable style in the naked bike category. Designed for riders who crave an exhilarating experience on two wheels, the Super Duke stands out with its aggressive stance and performance-oriented features. This bike is not just a mode of transportation; it's a statement, capturing the essence of street riding with an edge that only KTM can deliver. Its unique design and potent capabilities make it a formidable contender in the naked bike segment, appealing to both seasoned riders and newcomers looking to embrace the thrill of motorcycling. At the heart of the 990 Super Duke lies a beastly 999cc V2, four-stroke engine that produces a staggering 118 horsepower at 9,000 RPM. With a torque output of 100 Nm at 7,000 RPM, this bike promises exhilarating acceleration and a thrilling ride, whether you're slicing through city traffic or carving up winding country roads. The 11.5:1 compression ratio and the carburettor fuel system ensure that the power delivery is both responsive and engaging, while the six-speed gearbox allows for smooth and effortless gear changes. The Super Duke’s lightweight construction, at just 186 kg (410.1 pounds), combined with its impressive power-to-weight ratio of 0.6344 HP/kg, ensures that riders experience nimble handling and agility, making every ride a true adventure. The 2008 Super Duke is packed with features that enhance both performance and comfort. Its sophisticated chromium-molybdenum frame, coupled with WP USD front suspension and a WP monoshock rear suspension, provides a perfect balance of stability and agility. With a rake of 23.9° and a trail of 101 mm, the bike handles beautifully, offering precise steering responses that inspire confidence. The double disc front brakes with 320 mm rotors and a single 240 mm rear disc ensure strong stopping power, essential for spirited urban riding. Riders will also appreciate the electric starter and a generous 18.5-litre fuel capacity, which allows for longer rides without constant refueling interruptions. **

Pros

  • Powerful Engine: The 999cc V2 engine delivers exceptional performance, making the Super Duke a thrilling ride for those who love speed.
  • Agile Handling: Lightweight construction and advanced suspension setup provide excellent handling characteristics, perfect for both city commuting and twisty roads.
  • Aggressive Styling: The Super Duke’s bold design and naked bike aesthetics make it a head-turner on the streets.

Cons

  • Firm Ride: The sporty suspension setup may feel stiff for some riders, especially on longer trips or uneven roads.
  • Limited Wind Protection: Being a naked bike, it offers minimal wind protection, which might not be ideal for long-distance touring.
  • Seat Height: With a seat height of 855 mm (33.7 inches), it may not be the most accessible option for shorter riders, potentially limiting its appeal.
