I love this bike, ride 450s for e few years, then bought this bike, and suddenly i remembered how much fun motocross used to be.
Specifications
For years KTM has committed to the development of 2-stroke engines which are an advantage against 4-strokes in many aspects. With an unbeatable power-to-weight ratio, lower cost of acquisition and easy to maintain and service – there is no better choice than a two-stroke.
New MY 2011:
- New chassis (PDS)
- New airbox
- Air flow optimized intake boot between filter and carburetor
- New exhaust (new shape with bigger diameter at connection pipe)
- New two component rear silencer (better connection and bigger inner diameter)
- Newly developed cylinder (lower exhaust port, new timing and optimized exhaust control)
- Noticeable increase in power performance
- Higher torque
- Better rideability
