KIBBLEWHITE valve spring kit for KTM EXC 400, EXC 400 RACING, EXC 450, EXC 450 RACING, SMR 450, SMR 525 from 2000 to 2009

KIBBLEWHITE offers this valve spring kit for KTM EXC 400, EXC 400 RACING, EXC 450, EXC 450 RACING, SMR 450, SMR 525 from 2000 to 2009. The camshaft opens the valves and the springs close them. At high revs the spring must bring the valve back very quickly: if it is tired, the valve can no longer keep up and “floats”.

Why replace the valve springs?

The benefits:

• Safe running at high revs again.
• Essential with a hotter camshaft or steel valves, which are heavier than titanium.
• Quality steel springs keep their strength longer.

Why choose KIBBLEWHITE?

Kibblewhite chrome-silicon steel springs prevent valve float at high revs.

When should you replace the valve springs on your KTM EXC 400 RACING?

Hard hot starting, valve clearance that keeps closing up or a noisy timing chain: the valve train is wearing.
