Cylinder & crankshaft tuning kit 70cc from Motoforce Racing

Engine Pack Motoforce Racing cylinder + crankshaft 70 cast iron Minarelli vertical. This combo of cylinder and crankshaft including bearings and oil seals will save save headaches, money and time - the components fit perfectly and ensure smooth operation.

The MotoForce Racing 70 cc cast iron cylinder with 2-ring piston and HC cylinder head is the perfect choice if you want to replace the original cylinder with a more powerful, but at the same time very reliable model. In terms of power, the MotoForce Racing cylinder can develop 2 to 3 hp more than the original cylinder, but most importantly it has much higher torque.

The cylinder is perfectly supported by the RACING crankshaft from Motoforce Racing. This is a high compression racing crankshaft with silver-plated small end bearing. Unlike the standard version of this reinforced crankshaft, this Racing version has been additionally cast with plastic to increase pre-compression a little. Speeds up to 13,000 rpm are no problem.

Also included are two high-quality crankshaft main bearings with increased clearance for the high rpms and the matching oil seals.

Scope of delivery:

• Cylinder MotoForce Racing 70cc iron cast Minarelli vertical
• Crankshaft RACING bis 13.000 rpm Minarelli vertical 10mm piston pin
• Cranshaft Bearing Set Minarelli incl. oil seals

To ensure performance and reliability, we recommend combining the cylinder with a carburetor with at least 17.5 mm diameter, a tuning CVT and a tuning exhaust like the perfectly matching Stage6 Pro Replica.
