WHY RUNFAST IS THE HIGHEST QUALITY MOTORIZED BIKE ENGINE IN THE WORLD?
Heavier, stronger magnet rotor for more power! Other cheap bike engines use weaker, less powerful magnet rotors. Feel the difference!

Heavier, thicker cylinder bodies and crank case for strength and durability!
Heavy duty metal engine casing for added strength and durability
Wider front mount for better bike fitting accommodations of all bikes
Front and rear mounting studs are rugged thick 8mm. Cheap low quality kits use thin, brittle studs that break off.

High grade 8.8 standard for all bolting hardware. The low quality cheap kits use 4.4 grade that strip threads easily.

Balanced, heavy duty quality crank assembly with smooth rides.

Longer camshaft arms for easier disengagement

• Please also keep in mind that the motor will use a mix of gasoline and 2-cycle oil. The oil is used as a lubricant. Without it, the performance and longevity of the motor will be reduced. Please refer to the manual for further information including gasoline/oil ratios.
• If you have any questions,please contact us for technical solutions.
