Stage6 Tuning Kit cylinder + crankshaft Big Racing 86cc stroke 44mm Minarelli AM6

To get the maximum out of your 2-wheeler, we recommend to get a matching cylinder and crankshaft. We decided to put together a performance kit based on the new Stage6 Big Racing cylinders for mopeds with gearbox: Stage6 Cylinder BigRacing + Crankshaft 44mm for Minarelli AM6. The powerful tuning kit includes:

• aluminium cylinder 86cc with 5 transfer ports and bridged exhaust port, 44mm stroke
• 1-ring piston Vertex complete with pin, ring and circlip, 50mm
• high compression cylinder head, monobloc, aluminium
• cylinder gaskets (head and base)
• crankshaft, 44mm Top Performances

The Big Racing cylinder can be used for everyday riding, but considering its enormous power potential it is the perfect cylinder for any tuning project. Port timings are relatively low, cooling system volume is quite large, workmanship and materials are excellent - this cylinder is ready to go on the race track, be it for drag racing or long-distance circuit races.

In terms of output, the Big Racing cylinder plus Airsal crankshaft knock it out of the ballpark: in combination with an appropriate set-up (24mm carburetor, reinforced clutch, racing exhaust etc.) you can easily reach 25hp.
