Do you want the perfect power?
This is the racing cylinder with the right power and torque!
The largest and most powerful kit in this class on 70cc!

In contrast to the sport, this racing version has a large two-part exhaust duct with a central bar, longer, sharp valve times and a much higher compression!
In any case, we recommend using at least a 17.5 mm carburetor, better still a 19 mm carburettor.

The scope of delivery includes a set of seals with differently strong base seals to compensate for the timing and the squishy gap.

Huge inlet and outlet channels, as well as 4 overflow channels!
Tuning cylinders with the right power and torque - huge inlet and outlet ports and 4 additional performance overflow channels!
- Improved materials compared to the original
