FOR USE WITH 3 FULL SIZE DIRT BIKES Fit up to three motorcycles on the Big Days rack in the bed of any full- or mid- size pickup truck with our Moto Offset Kit. It lifts the two outside moto mounts towards the cab or upward to allow handlebars to clear when in the rack and eliminate as much bike interference as possible. For new customers, go to our Configure page and build a rack. Select your truck, add three Motorcycle Mounts, a Moto Ramp, a Third Moto Mount Riser Kit, and any other accessories you’d like. For existing customers with two Motorcycle Mounts, buy this riser kit and an additional Motorcycle Mount .
