More info

the little brother of Metrakit's "Pro Race 3", Metrakit 70cc "SP3" Cylinder Kit Derbi Euro 3 (D50B0) introducing notable improvements on the older version.

This 70cc aluminium kit includes cylinder, piston, cylinder head, stud bolts and gaskets. Metrakit suggests having a selection of cylinder gaskets of various strengths to adjust squish clearance.

The original cylinder was redesigned and now has 5 transfer ports instead of 6. Port timings were modified as well to get more torque and higher rpm. The exhaust port with its boost ports was not redone. The 47.6mm piston by manufacturer Vertex has one ring with anti-wear graphite coating.

Maxiscoot recommend the "SP 3" exhaust or another Hyper racing exhaust to go with the Metrakit 70cc "SP3" Cylinder Kit Derbi Euro 3 (D50B0). We also recommend replacing the crankshaft with a reinforced one such as the "Pro Race 70cc". Moreover, you should use a 21mm (minimum) or preferably a 24mm carburetor to get a powerful, well-balanced set-up
