ULTRA Add-on is designed to fit any motorcycle (Dirt, Cross, Enduro, Street, Sport, etc.) if it is not a single-sided swingarm one and the rear tire diameter is within the indicated limits:
MIN: 31cm and MAX: 75cm
The new ULTRA Add-on allows it to be used with any motorcycle with a rear wheel diameter with tires ranging from 31cm to 75cm. For minibikes, the holes below are used; for motorcycles of standard or large size, the holes are located above.
This addon can be attached to the V5 bodies as well if you would like to upgrade your Wheelie Trainer. It significantly extends the usability and the wheel sizes range.
