Tuning kit cylinder - crankshaft Stage6 R/T 70 Piaggio LC
Description
Piaggio LC tuning kit: Stage6 R/T 70cc cylinder and HQ crankshaft
For fans of Stage6: Stage6 R/T engine pack 70cc for 50cc scooters such as Piaggio Zip SP and SP2, NRG, Gilera Runner and many others.
The kit contains the following components:
- 1x cylinder kit Stage6 R/T 70cc
- 1x crankshaft Stage6 HPC MK2
- 1x crankshaft bearings Stage6 R/T
Stage6 R/T 70cc cylinder
The Stage6 R/T 70cc cylinder is a nikasil-coated aluminum cylinder with six transfer ports and bridged exhaust. It comes with a 47.6 mm piston, two-piece HC cylinder head and adapter plate for the external studs.
The CNC-machined adapter plate is screwed onto the engine housing and holds the cylinder via external stud bolts. This eliminates the need for continuous stud bolts, which in turn clears the way for further performance-enhancing modifications to the exhaust and transfer ports. The thermic properties are excellent - the combustion chamber insert is bolted to the cylinder at five points, each bolt is cooled by its own cooling pocket. The critical areas at the stud bolts are thus stabilized and the risk of piston seizure is minimized.
Reinforced Stage6 R/T crankshaft
The tuning crankshaft features precision manufacturing and adherence to exacting tolerances. The forged, CNC-machined 85mm connecting rod is extremely resistant and ensures maximum strength when used in racing engines, at the same time its design optimizes flow dynamics for enhanced performance.
The very precise balancing via lightweight metal inserts mitigates strong vibrations and ensures smooth running. The top-of-the-line crankshaft comes with a top quality small end bearing.
even more power for Piaggio scooters
To improve the Piaggio engine pack even further and increase the performance of the Stage6 R/T to a potential output of approx. 22 hp , we also recommend the following:
- Stage6 R/T Oversize CVT
- Stage6 Torque Control clutch
- 28mm Stage6 R/T intake
- Stage6 R/T exhaust
- Stage6 R/T internal rotor ignition
- Extended gearbox
Caution: The crankcase must be milled slightly for installation so that the cylinder base fits.

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.
