Already famous in the mecaboite/geared moped scene, finally available for scooters here at Maxiscoot for a very good price: the Top Performances 86cc Tuning Kit (cylinder + 44mm stroke crankshaft) Piaggio NRG / Runner (Piaggio / Gilera LC). With an excellent reputation regarding geared mopeds/mecaboites already established, Top Performances came up with this 86cc Aluminium Tuning Kit for scooters with Piaggio / Gilera LC engines (NRG, Runner, Zip LC, NTT, etc.).
The cylinder is made of Nikasil-plated aluminium with a 50mm diameter and 44mm stroke, 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 86cc Tuning Kit Piaggio NRG / Runner is a reinforced full-circle racing crankshaft with "extended" 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 Top Performances 86cc Tuning Kit Piaggio NRG / Runner is a Hyper Racing kit and develops 20/22hp in combination with the proper components:
- min. 28mm carburetor
- digital inner rotor ignition
- “Hyper Racing” exhaust.
The Top Performances Tuning Kit 86cc (cylinder kit + 44mm stroke crankshaft) Piaggio NRG / Runner includes two crankshaft bearings (C3 Polyamide cages) and oil seals.
Note: the crankcase has to be milled to make room for the 44mm crankshaft, and also for the cylinder base (d=56mm).
