Top Performances' response to popular demand: the Top Performances 77cc Tuning Kit NRG/ Runner (Piaggio / Gilera LC), available for a very good price at Maxiscoot!With an excellent reputation regarding geared mopeds/mecaboites already established, Top Performances came up with this 77cc Aluminium Tuning Kit for scooters with Piaggio / Gilera LC engines (NRG, Runner, Zip LC, NTT, etc.).
The cylinder kit 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 in this Top Performances 77cc Tuning Kit NRG/ Runner is a reinforced full-circle racing crankshaft with "standard" stroke - 40mm, 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 Top Performances 77cc Tuning Kit NRG/ Runner can be seen at the lower end of the Hyper Racing spectrum and develops 18/20hp in combination with the proper components:
- min. 28mm carburetor
- digital inner rotor ignition
- “Hyper Racing” exhaust.
The Top Performances Tuning Kit 77cc Piaggio NRG / Runner includes two crankshaft bearings (C3 Polyamide cages) and oil seals.
Note: the crankcase has to be milled at the cylinder base (d=56mm).
