DetailsAnother excellent product by Spanish manufacturer Metrakit, available for a very good price: Metrakit 50cc Aluminium Cylinder Kit MBK Nitro / Aerox.
The kit includes cylinder, piston, cylinder head and gaskets.
The 40mm aluminium cylinder has 5 transfer ports and a bridged exhaust port. The single-ring piston comes with piston pin (10mm) and circlips. The cylinder head is made from one piece (monobloc).
The Metrakit 50cc Aluminium Cylinder Kit MBK Nitro / Aerox is a "Racing" kit which is, as the name suggests, built for the race track, but also for everyday road use (regular maintenance necessary).Street-legal.
For racing, you should combine it with a 50cc racing exhaust, for everyday road use you can opt for a street-legal model (such as Yasuni, Bidalot or Doppler).We recommend a 17.5 to 21mm carburetor to go with it, again depending on the way you want to use it.We also recommend replacing your (worn down) original crankshaft with a reinforced one. Just have a look at our spare parts section.
