2012 KTM 150SX Review

The golden mean

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.

 

2012 KTM 150SX Features and Benefits

New for 2012:

» new linkage rear suspension
» new frame
» new swing arm
» new rear shock
» new front fork (bushings, seals and setting)
» new intake boot (better performance)
» new exhaust pipe (better power delivery)
» new kickstarter

 

New intake snorkel

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.

New exhaust expansion chamber

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.

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. It is also characterized by a particularly balanced geometry that combines playful handling with razor-sharp precision.

New linkage rear suspension

The two-strokes in the MX range from KTM are now also equipped with the elaborate linkage rear suspension system. Linking the shock absorber via a lever system provides high progressiveness and wide adjustment ranges. The 150 SX therefore feels at home, even on the most brutal motocross courses.

New swingarm

Apart from the new linkage rear suspension, there is the new cast aluminum swingarm, which is designed for minimum weight while supplying optimum lateral stiffness and defined longitudinal flexibility. This makes a major contribution to the excellent tracking stability of the 150 SX and its precise handling and extreme traction.

New telescopic fork setting

The further improved upside-down telescopic fork incorporating closed-cartridge technology now ensures even greater punch with a revised setting. At the same time, the WP fork with 48 mm (1.89 in) outer tube diameter bolsters the playful handling of the 150 SX.

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.
