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.The flow-optimized intake flange between airbox and carburetor on the 150 SX now ensures even better charging with fresh gas. This results in even freer revving and even more power in all RPM ranges for the liquid-cooled, two-stroke machine.The new exhaust expansion chamber on the 150 SX has not only improved in quality in conjunction with the two-stroke machine's exhaust control system, its optimized resonance chamber ensures an extra shot of engine power ‿ explosive, but dependable.The bodywork of the 150 SX with the very slim seat and radiator shrouds, plus excellent contact points perfect the bike's ergonomics, making handling even simpler and more precise.New Frame: The completely revamped frame on the 150 SX is made from high-quality chrome-molybdenum steel and is extremely light and torsion-resistant.
