The Metrakit 70cc Cylinder Kit "SP3" MBK Nitro / Aerox is one of the best racing kits on the market. It is the little brother of Metrakit's extremely powerful "Pro Race", the only difference is in cylinder head design - this one is a monobloc cylinder head. This SP 3 version was modified and improved over its predessor, for even more power.
The Nikasil-plated aluminium kit includes a single-ring piston and a cylinder with large exhaust port and 5 transfer ports. Performance and torque are quite impressive: 15 - 17hp at 13,500rpm and a 13:1 compression. All in all a very powerful racing cylinder at a very reasonable price.
This 70cc aluminium kit includes cylinder, cylinder head, piston, piston pin, stud bolts and gaskets.
We recommend combining this kit with a sports or racing exhaust, a reinforced crankshaft such as the "Pro Race 70cc" and a 21 -24mm carburetor to unlock its full potential.
