86cc Big Bore cylinder available for a very good price! With an excellent reputation, Top Performances came up with this 86cc Aluminium Tuning Kit for scooters with horizontal Minarelli LC engines. The cylinder is made of Nikasil-plated aluminium with a 50mm diameter, has 6 transfer ports, a bridged exhaust port and a modular high compression cylinder head. The exhaust port is very 'large' across its entire width giving it a unique look. Special attention was also given to the cylinder's external surface with a cooling canal enclosing the entire exhaust port for optimum cooling. The crankshaft included is a reinforced full-circle racing crankshaft with 'standard' stroke – 44mm, 85mm conrod, small end bearing 12x15x15mm. One of the unique features characterizing high-end crankshafts is the use of Tungsten weights instead of standard 'caps' for balancing. Regarding performance, the TPR 86cc can be seen at the lower end of the Hyper Racing spectrum and develops 22/24hp in combination with the proper components.
