HRC Power-Valve stopper bolt. (Ti)

Regular price $43.00

HRC had lots of trick bits, that were never available to the general public. This is one of those parts!

This bolt enables the adjustment of the powervalve on the 1992-2001 CR250, adding to the bottom end torque of the motor.

Machined in house, from Grade 5 6AL4v titanium, plus a titanium lock nut.  

Supplied with the bolt will be a photo copy showing instructions of how the adjutsment is achieved.

Since SpD Factory
Developments began, the Company ethos has remained unchanged – ‘Superb quality and nothing less’. Every item that we manufacture or product that we market from other manufacturers must answer one simple question – “Would we be proud to put that on our own bike?”. If the answer is no then we don’t sell it.



In a word, superb! With attention to detail even on a plain old bolt! Very happy with results and well worth the wait.
