We have updated the porting in the 2022 version which gives a better power curve and even more torque.

The 28.5cc is easy starting, runs cool, simple to tune and would be the most versatile engine around.

Big punch off the mark, lasts 30 minute finals and pulls a very respectable 20,000k under heavy load.

This winning combination will definitely slap a smile on your dial.
