Stage6 R/T 70cc cylinder Piaggio LC
Stage6 R/T 70cc Cylinder Kit MKI Piaggio NRG / Runner, top-of-the-range "Hyper Racing" kit with a 47.6mm diameter (70cc) developed by Stage6's R/T department ("Racing/Team") for Piaggio / Gilera LC.
The kit includes:
- Nikasil-plated Aluminium Cylinder with 6 transfer ports and a bridged exhaust port
- HQ Piston with extra thin piston ring
- High-Compression Modular Cylinder Head (anodised orange)

Innovative assembly Stage6 cylinder
The special adapter plate bolts to the engine case, the cylinder is mounted via external bolts so that there are no bolts cutting through the cylinder; this new design opens up all kinds of options for tuners to modify and optimize their engine (porting) without being subject to the usual restrictions. A Viton O-ring seal between adapter plate and cylinder makes future readjustments unnecessary.
Performance Stage6 70cc cylinder
Regarding performance, the Stage6 R/T 70cc Cylinder Kit MKI Piaggio NRG / Runner reaches 20 to 22hp and can easily be placed among the top 70cc high-end racing kits on the market. The thermal properties are excellent - the combustion chamber is bolted to the cylinder at five points, each coming with its own cooling pocket. These highly critical areas are thus stabilized and the risk of piston seizure is minimized.
Notes on installation
The 70cc cylinder must be fitted with an 85mm long stroke crankshaft, we recommend the Stage6 crankshaft. The crankcase must be opened up a little to make room for the cylinder base (D. = 56.1mm +/- 0.1mm, 10mm deep). A manual is included.
The cylinder fits only on the Stage6 R/T exhaust for Piaggio without further modifications due to the angle deviating from the original.
WITHOUT HOMOLOGATION / STREET APPROVAL.
How to Install a cylinder on a scooter, motorcycle or moped
The cylinder or cylinder kit is the heart of the engine on scooters, motorcycles and mopeds. It consists of a cylinder, a piston with piston ring(s), a cylinder head and gaskets needed for installation.
The service life of a cylinder depends on whether it has been fitted correctly.

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.
