Top Performances' response to popular demand: the Top Performances 77cc Tuning Kit MBK Nitro / Aerox (Minarelli horizontal LC), available for a very good price. With an excellent reputation regarding geared mopeds/mecaboites already established, Top Performances came up with this 77cc Aluminium Tuning Kit for scooters with horizontal Minarelli LC engines (MBK Nitro, Yamaha Aerox, etc.).
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 in this Top Performances 77cc Tuning Kit MBK Nitro / Aerox 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 MBK Nitro / Aerox 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 MBK Nitro / Aerox includes two crankshaft bearings (C3 Polyamide cages) and oil seals.
Note: the crankcase has to be milled to make room for the cylinder base (d=56mm).
