Regular price $13.00

Get your power valves working properly! 

Over time, along with 20+ years of use and wear, springs can loose there tension, making your powervalves work less efficently than they should. 

These are no longer availble from Honda, so we had some made!!

This is an EXACT replica of the OEM Honda part number 18531-KZ4-L30 and fit the 2003, 2005-2007 CR125 engines. 

This part is NOT used on the 2004 model.

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.
