DetailsFor all racing aficionados - the Metrakit 70cc Cylinder Kit "Pro Race 3" MBK Nitro / Aerox (12mm), the latest redesign of Metrakit's "Pro Race" cylinder.
With the new Pro Race 3, Metrakit set out to really improve on the older version. And they achieved that goal by improving the design of the combustion chamber with increased compression for more torque and power. Transfer port design also underwent an overhaul - 5 instead of 6, with modified port timings. The exhaust port with boost ports was not redone for this version.>
The Pro Race 3 cylinder is complemented perfectly by the single-ring piston (12mm) by manufacturer Vertex, with a 47.6mm diameter and anti-wear graphite coating. A cylinder gasket kit and cylinder spacers for adjusting squish clearance are included.
The Metrakit 70cc Cylinder Kit "Pro Race 3" MBK Nitro / Aerox (12mm) is definitely one of the most powerful 70cc kits; we recommend adding the Pro Race 70cc crankshaft and the Pro Race 3 exhaust to get a well-balanced set-up. We also recommend a 24mm or 28mm carburetor for even more power.
