heavy-cheeked HPC racing crank increases the pre-compression in the cases for improved filling. The extra inertia improves performance and the performance moves to the upper rev range. The crank design, with plastic inserts, only slightly increases the weight of the crank compared to the original, making it ideal for standard 50cc engines, but also a very good match for 70cc cylinders. Delivery includes small end bearing. Suitable for scooters fitted with the Peugeot vertical Euro 1 2-stroke 50cc engine. ***PLEASE CHECK ENGINE TYPE BEFORE PURCHASING*** The Euro 1 engine was fitted on a range of Peugeot 50cc models up until 2002/3 and uses a manual oil pump. The crank bearings on the Euro 1 engine are both the same size (20mm x 52mm x 12mm) whilst the later type Euro 2 engine require different sized crank bearings.
