Cylinder Head Stage6 BigRacing \/ Streetrace 77cc Derbi Euro 3 \/ 4

Stage6 Cylinder Head Big Racing 77cc Derbi Euro 3, spare part for Stage6 Big Racing 77cc cylinder for Derbi Euro 3 (Derbi Senda etc.)

Detonation and debris in the engine can cause serious damage to the cylinder head; if the damage is too extensive, performance will be affected and there is no way around getting a new head.

This is the replacement for the original head of the Stage6 77cc Big Racing cylinder kit so your engine will be as good as new.

Note: Models with Derbi Euro 4 engine use a slightly smaller temperature sensor (thread: M12 x 1.5) than the Euro 3 models (M14 x 1.5). To fit the smaller Euro 4 sensor on the cylinder head, you will need the adapter MF96.91010.
