Racing causes extreme wear and tear on the clutch therefore it is important to inspect clutch for wear after each racing event.
The heavy Duty clutch spring kit is the answer to your KTM 50 SX clutch spring problems. The new springs are wound from high quality SS round wire providing fewer coils and higher pressure than the old green flat wire springs. This allows more space between the coils and less opportunity for coil bind. The old springs when installed were very close to coil bind, when a spring binds it loses some of its length and strength. By not allowing the new springs to bind they will last longer and provide a more consistent feel. The high quality spring wire will hold its strength longer than the old flat wire springs.
EHR Reed Valve System especially made for the KTM 65sx.

The reed valve housing is larger for better flow and increases the volume in your crankcase for better bottom power.
