A fairly powerful cast kit after the Top Performance "DUE PLUS" for PIAGGIO / GILERA motor scooter, it is a minacrom cast iron cylinder. This kit has 6 transfers including 4 opposite and two are placed later to optimize the filling of the admission.
The exhaust is normal (oval) and the bi-segment piston is high-grade silicon with a reinforced alloy. This kit is relatively torquey, powerful and solid, some up to 25,000 Kms with this type of kit by changing the piston every 10,000 Kms without even a reborage. Level tip is also very impressive.
You can also do a lot of kms because it is very solid (it's the magic of minacrom cast iron) and you can bore it cheaply in 48.5mm diameter (we have all the spare parts).
The combustion chamber of its cylinder head is in high compression studied and hemispherical with polished finish. Delivered as presented.
We recommend to mount it at least with: racing exhaust, cold racing candle, carburettor 17,5mm, reinforced bearings and crankshaft as well as racing variator.
Bore: 48mm
Displacement: 71cc in race 39,3mm
Compression Ratio: 1: 12.3

Optionally we offer a stage 1 preparation, this preparation is a modification of the channels and exhaust light by increasing the diagrams and improving the pipe, it increases the performance of the cylinder. An improvement of the piston and skirt stocking is also included in this modification. Allow a little extra time for this preparation!
