Here is the head cylinder 2Fast 90cc MBK Nitro / Aerox.
This 2Fast head cylinder offers a 90cc cylinder capacity thanks to the use of a 50mm diameter piston (axis 13mm) on a 45.8mm stroke (and 90mm rod).
Made of high-quality aluminium, it has 6 inlet transfers and two-part exhaust light with a bar. A decomposable plot head and recognizable at first glance thanks to its famous anodized blue overcoat, characteristic of the brand.
Very efficient, it is one of the most powerful cylinders of more than 80cc on the market.
It is therefore essential to mount it with the Hyper Racing exhaust system such as the 2Fast 86cc or the Stage6 RT 90-100, a carburettor of at least 30mm and a digital ignition with high-end internal rotor.
