2012 Ktm 150 SX, lite as a 125/faster than a 250F - The perfect combination of the playful handling of a 125 coupled with engine power that comes close to that of a 250. With even better performance than before, a new frame and new rear suspension, the 150 SX can exploit its weight advantage over the competition to the fullest. So well-equipped that you can really show your teeth to many a 250cc four-stroke machine.
