The Economy Motorcycle Wheel Chock from Extreme Max Products is an economical way to secure your motorcycle’s front tire for light-duty travel or storage applications. The three-piece chock is constructed of durable 1" tubular steel and assembles quickly. Once assembled, the chock mounts to your motorcycle trailer or truck bed and fits motorcycle tires up to 5" wide. Specifications: Height: 13.5" Interior Width: 5.25" Total Length: 14" Four-hole mounting pattern, spaced 6" front to back, 6.25" wide (center of hole to center of hole) Note: The Economy Wheel Chock is intended for light-duty applications and is not intended for use as an unassisted stand for your motorcycle; straps are required for safely securing your motorcycle and are not included. The chock MUST be mounted to a solid surface for safe use. Due to the variety of mounting surfaces the Economy Wheel Chock may be attached to, mounting hardware is not provided and must be purchased separately.
