(Fits Most Full Size Bikes From 85cc Up) The LOCK-N-LOAD PRO Moto Transport System securely holds your dirtbikes in your truck, van, or trailer without the use of tie-down straps, floor anchors or wheel chocks. It takes an enormous amount of pressure off of the fork seals during transit, and it frees up valuable space allowing the transport of more motorcycles or gear. Additionally, the Lock-N-Load PRO can quickly be removed from the trailer floor leaving only the low profile mounting plate. The Lock-N-Load PRO is fully adjustable and designed to work with dirt bikes from 85cc motocross bikes to 690cc trail bikes with a max weight of 315 lbs. See size specs for exact size limits. For smaller bikes see the Lock-N-Load MINI Pro.
