                                  Honda CRF110F upgraded valve springs for OEM cylinder head. When running OEM or aftermarket camshafts, the weak OEM valve springs hit a limit from 10,300-10,800rpm depending on the camshaft.
This HD Valve spring kit will support RPM up to 12,000RPM unlocking an additional 20% more overrev. This allows a shorter gearing setup to really help get out of the idle-3,000rpm range where the semi auto clutch is engaging. All while allowing more top speed in every gear.
 
Highly recommended to be used with larger diameter exhaust - Yoshimura and Rocket Big Bore as smaller exhaust we generally see power fall off around 9500-10,000rpm unless a ported race head is added. 
 
*USE ONLY 1 INTALE AND 1 EXHAUST SPRING, OEM SPRINGS REMOVED COMPLETELY.
