Whites Front Wheel Chock 3The Whites Front Wheel Chock 3 is the perfect minimalistic way to stabilise and securely transport your motorcycle in your van or on your trailer. The wheel chock prevents your wheel from moving sideways, which will cause your tie downs to go loose and your bike fall over. Constructed from 20mm diameter steel tubing, the chock is strong and durable, while the pre drilled holes enable quick and easy mounting. Features: Compatible with tyres up to 145mm
