GRUPPO TERMICO 80CC E TESTA D.47,6 C LUNGA

Complete cylinder kit (incl. piston and cylinder head) Sport Pro 80cc long stroke  by Athena. Nikasil-plated aluminium, 5 transfer ports, single exhaust port, single-ring piston (12mm pin) and high-compression cylinder head. It is similar to the Sport Pro series cylinders, but can be installed with a longer stroke (43mm, 44mm for Piaggio engines) crankshaft (85mm rod) increasing displacement to 80cc. This is designed for low/mid range torque resulting in good acceleration. We recommend a 21mm carburetor minimum as well as a racing exhaust (such as Yasuni C16, Roost, R1400 etc...). With the appropriate components and adjustments, you can expect 17 to 19hp (15hp on vertical Minarelli AC engines). Note: this kit requires advanced tuning!
