The Motoforce Racing 50cc Aluminium is a top-grade mid-race cylinder kit with a price/performance ratio that is hard to beat.
In fact, you'll get this mid-race cylinder for the same price that will usually buy you a humble sport cylinder from one of the better-known manufacturers.
This cylinder is made of aluminium, thus offering excellent thermal properties. The nikasil-coated liner ensures minimal wear and therefore great durability.
This is a mid-race kit which is high revving and produces higher power than a 'sports' kit.
10mm gudgeon pin.

Hi, they are not used on the race kits, the nipple on top the head is a bleed screw for bleeding out any air in the cooling system- most people just block the two inlets off on the carb when fitting them (loop them together) or it is also fine just to leave them open.
The Motoforce mid-race cylinder is a high revving cylinder kit and would need to be used with a full circle race crank such as the Motoforce Evo
