MALOSSI Crankshaft shaft Ø15 mm - stroke 51 mm (manufacturer reference: 5316594)
Malossi crankshaft designed for Vespa/Ape units, intended for urban modifications and competition. Constructed from reinforced aerospace-grade steel and vacuum cast, this engine shaft features a "viper head" profile connecting rod to reduce mass while maintaining the necessary rigidity for the operation of the connecting rods and pistons.
Visible technical specifications: shaft diameter 15 mm, stroke 51 mm. The product includes practical improvements for the transmission: reworked threading for better grip, resized key, and special nuts provided. Tungsten inserts serve as counterweights to enhance the dynamic balancing of the entire assembly.
Two versions available depending on the cases: small frame (different connecting rod lengths) and version for engines with rotary valve intake, with optimized intake phase at the half-case level.
Product intended for competition use in appropriate locations and compliant with the regulations of sporting authorities. Motoblouz disclaims any responsibility in case of non-compliant use.
