The athena sport kit is the best based kit between strength / performance as well as torque / high speed. With its diameter 47,6mm it will offer you 69,93cc real race origin. Its specially designed normal exhaust will offer you better sweeping, very good performance in both torque and high speed and especially preserve excellent strength unlike a bar escapement for example.
The cylinder uses the most high-end alloys with a luxury nykasil treatment, the finish is impressive, we highly appreciated the duct design worthy of the biggest racing kits. The piston is high silicon content, recess in mono segment in order to exploit good high speeds, it is well aligned cylinder. The breech is certainly not part of it, but with its high-end alloy, its polished frustoconical chamber ...
it has nothing to envy to the model bie-part to be a slightly less good cooling. In short this kit will offer a breathtaking torque, excellent high revs, perfect strength ... It even comes with carbon slats to properly follow your carburation, several base seals to properly stall your squish ...
We recommend it with at least : 19mm carburetor, racing exhaust (athena sport advised), reinforced crankshaft and bearings, adequate cold candle.
