Race quality 58mm x 110mm crankshaft for CasaCase engine casing. Manufatured by Primatist exclusively for Casa Performance, there simply is no better crank on the market - period. Race proven by the 'Casa Lambretta Racing Team' scooters, these are simply indestructable. Fit and forget.
Remember that a 110mm conrod length is standard for the CasaCase engine casings as the cylinder gasket face is 3mm higher than std. Lambretta casings!
