Performance TPR 80 Sport cylinder As expected from Top Performances, this kit meets all expectations. The TPR 80 is a robust cast iron cylinder with oval exhaust port for max torque and a split cylinder head for improved cooling. With the right setup — 19 to 24mm carb and a suitable race exhaust — 12 to 14 hp are realistic. Its real strength lies in midrange torque and acceleration, though it still delivers in the upper powerband. A reinforced crankshaft is recommended for handling the added power.
