-NEW PISTON DESIGN 

The 100cc pistons have a 50mm diamter. It uses three 50mm x 1.5mm which helps in sealing and increases horsepower.

The piston pin has a diameter of 12mm which helps against wear and tear.

What type of bicycles with these racing engines fit on?
The racing engine requires a clearance of at least 15 inches in height on the seat tube (the part of the frame under the seat) and 14-15 inches in length on the down tube (the diagonal part of the frame), and it is approximately 5 inches wide. 

We recommend installing these kits on bicycles with a 1 inch diameter seat tube and with a 1-1.25 inch diameter on the down tube.
We have a gallery available on our website and you'll be able to view a selection of bicycles that these engines have been installed on.

Designed to fit most 26” Bicycles (Cruiser, Road, Mountain, Chopper) with a Standard V-frame. Approximately 9-11” of clearance is necessary between the top bar and bottom bracket with a frame diameter of around 1”.
