70cc cylinder by renowned Italian manufacturer 2Fast and not meant for the faint at heart, but for those who are looking for maximum power. It is the only 70cc cylinder series by 2Fast, and instead of modifying one of their other cylinder models, they designed an original 70cc racing cylinder. It is designed for crankshafts with standard stroke and 85mm connecting rod.

Top quality aluminium cylinder with a very resistant Nikasil coating accompanied by 2Fast's famous anodized blue cylinder head. More details:

  • 6 transfer ports
  • divided exhaust port
  • modular cylinder head
  • 1-ring piston, 12mm pin

2Fast put a lot of thinking and effort in recalculating port timings and redesigning transfer port layout resulting in stand-out performance in this category; in combination with the right components (28mm carburetor, digital internal rotor ignition and high-end racing exhaust), this cylinder kit can reach 22 to 24hp. Definitely a state-of-the-art tuning cylinder that will get you ahead of the competition.

Note: the crankcase / motor block has to be milled a little to make room for the cylinder base.
