DETACHABLE HEAD KIT 125 (WITH 1 INSERT)

Combination that does not require compromises between mechanical seal and performance. Cap machined from solid with substantial increase in cooling power and flow of coolant in the spark plug area. Increased mechanical resistance to stress and conferring of screw tightening force to 15/18Nw for a better seal of the combustion insert on the cylinder plane.
Combustion chamber insert with optimized profile and positive squish band. It gives greater thrust from low revs and greater extension at high revs.
