Need more power, but want to keep your feet on the ground? Then reach out for the 85 - 115 ccm class. A longer transmission, a 19er carburetor and a tuning exhaust system will be necessary. Add a 4er disc clutch to that. Ranges up to 10 horsepower, speeds to 95 km/h and heftier acceleration are yours. Our tip: the MALOSSI 112 ccm direct induction!
SERIE PRO also manufactures cylinders for Vespa 50 1° Serie V5A1T -> 92876. We've modified them so that they fit the first 50's Vespas with their smaller cylinder base connection in motor block.
