NEW RACE TB PARTS CAMSHAFT
FOR YX 2 VALVE HEAD and ZS155 (GPX)

Compared to the original cam it has eccentricities that guarantee a better low-mid shot with a more linear and less pointed delivery curve. Ideal solution for those looking for immediate power and torque right from the start, with medium / low performance even higher than 1.5Cv, all at the expense of the short and less useful peak of power at higher revs given by the chinese cams.
It is therefore the optimal solution for those who run championships with power limitations, such as italian 12 Pollici challenge, and wants an almost "electric" motor, immediately ready, which prefers shooting qualities, linear and without peaks that make it exceed the bench trial test. Perfect combo when installed with 64mm big bore TB parts.

It fits perfectly without any modification, in YX150 and 160cc and ZS155 cylinder heads.

COMPATIBILITY: YX 2v (150, 160cc and beyond), Zongshen 155 (ZS155, GPX155) equipped with original head.
