The 2011 KTM 250XC-F and 350XC-F off-road motorcycles are based on the respective SX-F motocross models. Both new models use SX-F style frames and the new-for-KTM linkage rear suspension system. The 350XC-F will be used by KTM factory riders Kailub Russell, Cory Buttrick and Charlie Mullins in the 2011 GNCC series.
The 350XC-F uses a 349.7cc single-cylinder four-stroke engine while the 250XC-F uses a 248.6cc single-cylinder four-stroke. Both engines use a Keihin electronic fuel-injection system with 42mm throttle bodies.
The transmission systems have been revised (in the 350XC-F’s case, it gets a six speed transmission compared to the SX-F’s five-speed gearbox) and KTM added a 2.51 gallon gas tank (compared to the 1.98 gallon tank on the SX-F models.
The XC-F models are also equipped with hand guards and a side stand while the SX-F’s 19-inch rear wheels are replaced with 18-inch wheels. While the 350SX-F uses an electric starter and the 250SX-F a kickstarter, the two new XC-F models are equipped with both starters.
The 2011 KTM 350XC-F and 250XC-F will arrive in North American dealers in January 2011.
