Cammers' pulley on the exhaust side for motorization 1.2 / 1.2 PureTech / 1.2 THP / 1.2 VTI The camshaft pulley plays a central role in the synchronization of motor cycles. Brought by the distribution belt, it provides the precise opening and closing of the valves via the camshaft, in line with the crankshaft. On a 1.2 VTI engine, this part guarantees flexible operation, optimized performance and controlled consumption. A worn or deregulated pulley can cause poor setting, power losses, or even an engine breakage. Its preventive replacement is therefore essential when revising the distribution.
