DON'T TRUST YOUR BIKES IN ANYTHING LESS! The Lock-N-Load Moto Anchoring System securely holds your motocross bike into your 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 can quickly be removed from the trailer floor by unscrewing the 4 thumb screws leaving only the low profile mounting plates. Each plate has a D ring for additional anchor points on your trailer floor.
