Description
Tuning Kit Cylinder + Exhaust Stage6 R/T 70cc Minarelli horizontal LC – High-End Racing Tuningkit for racing bikes with liquid-cooled Minarelli engine (Minarelli horizontal LC)
The kit consists of the following components:
– Cylinder Kit Stage6 70cc R/T MK 1 Minarelli horizontal LC
– Exhaust Stage6 R/T 70cc Minarelli horizontal
The Stage6 70cc R/T MKI Minarelli horizontal LC cylinder is an aluminium cylinder (with Nikasil-coated bore) with 6 transfer ports and bridged exhaust. The cylinder comes with a 47,6 mm piston, a modular HC cylinder head (high compression), a special exhaust flange for the S6 R/T exhaust and an adapter plate with offset studs for Minarelli horizontal engines (original or OEM replacement).
The exhaust is hand-welded in Italy from 0.8 mm thin sheet steel cones. It comes with a spring-mounted carbon silencer for a clean, not over-the-top racing look. Please note: the exhaust is delivered with a “racing finish”, i.e. it is not painted! We recommend to regularly apply a grease spray to prevent the exhaust from rusting.
In terms of performance, the Stage6 70cc R/T Piaggio NRG / Runner engine pack plays in the first league, the potentially feasible power is about 22 hp, other performance-enhancing components must be installed to achieve this output: reinforced crankshaft with 85 mm conrod, Stage6 R/T oversize variator, Stage6 Torque Control clutch, Stage6 R/T 28 mm intake system, Stage6 R/T internal rotor ignition, and an extended gearbox.
Please note that when using this kit, the crankcase must be bored open to make room for the cylinder base (see the installation instructions for more information).
