WASHINGTON -- Federal officials have recalled about 20,000 KTM off-road motorcycles because their fuel tanks can leak, posing a fire hazard.

The leaks are caused when the seal around the motorcycles' fuel tank loosens.

KTM North America Inc. has received 5,114 reports of leaking fuel tanks, according to the U.S. Consumer Product Safety Commission. CPSC has received one report of a minor chemical burn.

Model numbers included in the recall are: model year 2005 250SX-F; model year 2006 200XC, 200XC-W, 250XC-W, 250SX-F, 250XCF-W, 300XC, 300XC-W, 400EXC-G, 450XC-G, 450EXC-G, and 525EXC-G ; and model year 2007 125SX, 144SX, 250SX, 250SX-F, 450SX-F, 505SX-F, 200XC, 250XC, 300XC, 450XC, 200XCW, 250XCW, 300XCW, 400XCW, 450XCW, 525XCW, 250XC-F, and 250XCF-W.

The recalled motorcycles were sold at KTM dealers nationwide from November 2004 through April.

People who bought the motorcycles should stop using them immediately and contact their local KTM dealer to schedule a free repair.
