- Make:

- Model:
- 250 SX
- Year:
- 2010
The answer to true riding pleasure and a guaranteed podium place in the MX1 class. The overall performance and agility of the traditionally powerful and lightweight 250 SX competes with that of the four-strokes. A superior two-stroke weapon in terms of serviceability and user friendliness. Extremely robust with an ultra-light frame and additionally optimised chassis, the 250 SX shows the rest how it’s done!
