2015 KTM 450 SX-F, 2015 KTM 450 SX-F POWER FOR ALL With the 450 SX-F, KTM has a winning motorcycle in its range, which derives its potential from a high-capacity engine and a chassis perfectly tuned to the power unit. The 450 SX-F is the no. 1 choice for the official KTM factory team in the AMA Championship. No wonder; the compact SOHC engine guarantees brutal yet controllable power with its revolutionary injection technology. Above all, the 450 SX-F scores highly compared with other large 4-strokes in terms of performance and handling. Ideal for every motocrosser who sees plenty of torque, ample on-tap power and a controllable ride as their complete package. Standard Features May Include: ENGINE The compact 60hp powerhouse, featuring an overhead camshaft and state-of-the-art electronic fuel injection system, excels with unrivalled performance and highly efficient power development. Newly developed oil strainer sealing rings are used for MY 2015 to provide better durability in the most extreme conditions and a longer service life. PISTON In the cylinder with a bore of 95 mm, an extremely light, box-in-box, forged piston works away, making a significant contribution to the engines low vibration level and engine-speed strength on account of its low weight. The compression ratio is 12.6:1. ENGINE MANAGEMENT SYSTEM (EMS) In conjunction with the revolutionary injector position developed by KTM, the Keihin engine management system, with electronic fuel injection and 44 mm throttle body, ensures spontaneous responsiveness and maximum engine performance. Numerous connectors on the wiring harness are enclosed in rubber grommets to protect them from steam-jet pressure. Various engine characteristics can also still be selected via the EMS, with a map-select switch available as a PowerPart. Furthermore, a user-setting tool (also available as an option) allows data to be read from the bike by laptop and the mapping, ignition and fuel injection to be modified in a matter of a few mouse clicks. WHEELS The wheels fitted for MY 2015 feature black coated, high-end Excel rims with lightweight, CNC-machined hubs and spokes with lightweight aluminium nipples, allowing highest levels of stability to be achieved, while keeping weight to a minimum. New Dunlop Geomax MX 52 tyres were developed in collaboration with the KTM USA factory team and offer perfect traction with top performance. The new rear sprockets save 50 grams in unsprung mass. BRAKES High-tech brakes from Brembo have always been standard equipment on KTM offroad bikes and, together with the lightweight wave brake discs, they are the measure of all things in terms of brake technology. As the best brakes in the motocross class, they remain unchanged for MY 2015.
