Stage6 R/T 70cc cylinder

The Stage6 R/T 70cc cylinder is a nikasil-coated aluminum cylinder with six transfer ports and split exhaust. It is supplied 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 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 Minarelli scooters

To further improve the Minarelli horizontal engine pack and make optimum use of the kit, we also recommend

• 28 mm intake manifold Minarelli
• 28 PWK Stage6 R/T carburetor
• Stage6 R/T internal rotor ignition by PVL Minarelli
• Stage6 Racing Torque Control clutch
• Stage6 R/T Oversize CVT
• Stage6 R/T 70 exhaust Minarelli horizontal

By combining these components, you can achieve around 22 hp at the wheel.
