Overview

### 2021 KTM 350 SX-F: A Cross-Motocross Marvel For 2021, the KTM 350 SX-F stands as a prime contender in the competitive cross-motocross arena, expertly blending the agility of a 250cc machine with the robust power of a 450cc bike. This motorcycle is engineered for both seasoned racers and enthusiastic weekend warriors, promising an exhilarating ride that meets the demands of any track. With its striking orange, white, and black color scheme, the 350 SX-F not only catches the eye but also embodies the spirit of KTM’s performance-driven lineage. At the heart of the 350 SX-F is a finely-tuned 349.7cc single-cylinder, four-stroke engine. This powerhouse, with a bore and stroke of 88.0 x 57.5 mm, produces a responsive throttle response that delivers precise power across the rev range. The clever use of Keihin EMS ignition and liquid cooling ensures optimal performance even under strenuous conditions, while the efficient 5-speed gearbox allows for smooth gear transitions, keeping you in the power band whether you’re tackling tight corners or long straights. Weighing in at a featherlight 99.5 kg (219.4 lbs), the 350 SX-F offers exceptional handling and maneuverability, allowing riders to tackle various terrains with confidence. KTM has loaded the 350 SX-F with cutting-edge features designed to enhance both comfort and performance. The central double-cradle frame made from 25CrMo4 steel provides a robust yet lightweight foundation, while the WP XACT suspension system—boasting 310 mm of front travel and 300 mm of rear travel—ensures that every bump and jump is absorbed with ease. The Brembo hydraulics on the wet multi-disc clutch deliver seamless power transfer, and the electric starter ensures that you’ll be up and running with the push of a button. With a ground clearance of 370 mm and a seat height of 950 mm, this bike is well-equipped to handle various riding styles, allowing for an exciting experience on the track. **
