Exhaust valve kit - Suzuki RM-Z 450 ('08-'17) / RMX 450 Z ('10-'17) - ProX

Exhaust valve kit (steel) and springs from ProX for Suzuki RM-Z 450 (2008-2017) / RMX 450 Z (2010-2017).

ProX uses the best materials and the steel valve and spring kits provide an affordable solution for replacing titanium valves. Steel valves have a lifespan three times greater than titanium ones, and to compensate for the heavier weight of the steel valves, the kit comes with reinforced valve springs. No engine modifications are required.

The kit includes:
- exhaust valve x 2
- exhaust valve return spring x 2.
