The little brother of Metrakit's "Pro Race 3", the Metrakit 70cc "SP3" Cylinder Kit Derbi Euro 3 (D50B0) with notable improvements over 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 was not redone. The 47.6mm Vertex piston comes with 1 ring with anti-wear graphite coating. Performance and torque are quite impressive: 15 - 17hp at 13,500rpm and a 13:1 compression.
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.
