Vehicle Information
KTM 450 EXC-R Dirt Bike (2008-2011)
The KTM 450 EXC-R and EXC (2008-2011) is a renowned enduro motorcycle, celebrated for its off-road performance. These models, featuring an engine displacement of approximately 449.3 cc, underwent significant developments during this period. The 2008 model year introduced a major redesign, replacing the previous RFS engine with the new XC4 engine and featuring a new chassis. This innovative engine boasted a single overhead cam and separate engine and transmission oil systems, enhancing oil cleanliness and thermal management. The chassis also received updates, including a new chromoly frame and a redesigned swingarm. A further significant evolution occurred in 2011 with an entirely redeveloped engine, more compact and lighter, incorporating a common oil circuit and electronic fuel injection (EFI) for improved responsiveness. Trims such as the "Sixdays" and "Champions Edition" were also offered, providing specific enhancements. FAQ:
