PROGRESSIVE DOUBLE VALVE SPRING

░ YUMINASHI STD150 HEAD & X31 LS1 HEAD

This Progressive Double Valve Spring Set is mentioned for the bigger valve heads like PCX150, SH150i ABS, YUMINASHI STD150 and YUMINASHI 31/24.8mm big valve X31 LS1 Head. 

If you install the STD150 Head on your PCX125, then this double valve springs set is a real must because the original valve springs from the PCX125 and PCX150 start to float, and limit your RPM's, earlier before the electronically limiter kicks in.

**These valve springs come standard in the YUMINASHI X31 LS1 Head for PCX125. 

PRODUCT CODE: 14752-KZR-000

PRICE: 1,800THB / 46.00€ Exclusive V.A.T.

**This valve spring set can not be installed in a genuine 125cc head. If you have a PCX125 or SH125i ABS then you need to install the 14752-KWN-000 double valve spring set...
