Tuning Kit cylinder + exhaust Stage6 R/T 70cc Piaggio
Description
Tuning Kit Cylinder + Exhaust Stage6 R/T 70cc Piaggio - high-end racing tuning kit for racing bikes with liquid-cooled Piaggio engine (Piaggio LC)
The kit includes of the following components:
The Stage6 70cc R/T MKI Piaggio 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 Piaggio 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).

Tuning Level: High End racing
We categorize our products into different performance levels Original, Sport, Racing and High End , so that our customers can choose the right parts for their setup. It is really important to combine parts that belong to the same tuning level, this is especially true for cylinders, crankshafts and exhausts.
High End Racing products are exclusively designed for racing and should only be handled by tuning pros with the appropriate technical know-how. High-end racing parts often require modifications or machining of certain elements to accommodate the often larger components (larger crank webs, larger intake, etc.). Whether you stick with 50cc or increase the displacement, high-end racing parts offer much higher performance than the original parts and are the most powerful tuning parts.
Note: To ensure the reliability of the engine, it is important that the parts are compatible and that you do regular maintenance on your two-wheeler.
Aluminium cylinders
Aluminium cylinders are more powerful than cast iron cylinders, but require more regular maintenance and must be combined with different components such as a reinforced crankshaft and a larger carburetor.
How to run in an aluminium cylinder?
Aluminium cylinders should be run in for about 200 kilometers , and you should use a fully synthetic engine oil.
Note: To ensure optimum performance and reliability, it is advisable to measure the squish clearance. Just have a look at our tutorial How to adjust squish clearance.
