Taking the Vespa PX125 to new heights of performance, Malossi’s 177 engine kit is designed for fast road and touring use and is claimed to increase power by up to 18-25hp depending on final spec and setup.
The cylinder is made from nickel-chromium plated aluminium and has seven enlarged transfer ports and a bolt-in steel exhaust stub. The piston is a lightweight affair with twin rings for efficient sealing, and the replacement cylinder head has been designed to improve cooling.
