  • Nikasil-plated Aluminium Cylinder with 6 transfer ports and a bridged exhaust port
  • HQ Piston, 12mm pin, with extra thin piston ring
  • High-Compression Modular Cylinder Head (anodised orange)
  • R/T Cylinder Spacer / Adapter Plate, ground-breaking new design
  • R/T Exhaust Flange + Adapter Plate

The special adapter plate bolts to the engine case, the cylinder is mounted via external bolts so that there are no bolts cutting through the cylinder; this new design opens up all kinds of options for tuners to modify and optimize their engine (porting) without being subject to the usual restrictions. A Viton O-ring seal between adapter plate and cylinder makes future readjustments unnecessary.

Regarding performance, the Stage6 R/T 70cc Cylinder Kit MKI MBK Nitro / Aerox reaches 20 to 22hp and can easily be placed among the top 70cc high-end racing kits on the market. The thermal properties are excellent - the combustion chamber is bolted to the cylinder at five points, each coming with its own cooling pocket. These highly critical areas are thus stabilized and the risk of piston seizure is minimized.

The exhaust flange is attached with 3 bolts. It is suitable for Stage6 R/T exhausts, other flange types are available.

Note: you'll have to mill in the crankcase to make room for the cylinder base (d = 56.1mm +/-0.1mm, 10mm deep).
This Stage R/T cylinder kit can only be combined with a Stage6 R/T exhaust.
