Overview

Introducing the 2009 KTM 450 SX-F, a fierce contender in the enduro-offroad segment that embodies the spirit of competition and adventure. Built for serious riders who demand performance and agility, this machine delivers an exhilarating experience on both the track and rugged terrains. Renowned for its lightweight design and robust features, the 450 SX-F has carved a niche among motocross enthusiasts and off-road adventurers alike, offering a perfect blend of power, precision, and durability. At the heart of the 450 SX-F lies a potent 449.3cc single-cylinder, four-stroke engine, boasting a compression ratio of 12.5:1. This powerhouse is finely tuned with a Keihin MX FCR 41 carburettor, ensuring smooth throttle response and optimal power delivery across the RPM range. The 4-speed gearbox, coupled with a hydraulic wet multi-disc clutch, facilitates seamless gear shifts, allowing riders to navigate challenging terrains with ease. With its impressive 300 mm (11.8 inches) of front suspension travel and 335 mm (13.2 inches) of rear travel, the 450 SX-F excels at absorbing shocks and maintaining stability, instilling confidence in riders when tackling obstacles and jumps. The 2009 KTM 450 SX-F is loaded with advanced features that enhance both rider comfort and performance. Its central double-cradle frame made from 25 CrMo4 steel, combined with an aluminum subframe, provides exceptional rigidity while keeping the weight down to just 104.6 kg (230.6 pounds). The liquid-cooled engine ensures optimal temperatures, even during the most punishing rides, while the electric starter ensures quick and reliable starts. Not to be overlooked, the bike's striking orange color and aggressive styling make it stand out in any lineup, appealing to enthusiasts who appreciate aesthetics as much as performance. **
