Description
Acebikes CapStrap – Open-Axle Tie-Down System for BMW Motorcycles
A rear-axle tie-down solution for BMW models with a 53 mm hollow axle
The Acebikes CapStrap is a motorcycle tie-down system designed specifically for BMW motorcycles with a single-sided swingarm and a 53 mm (5.3 cm) hollow rear axle. By routing the strap through the center of the rear axle, CapStrap helps keep the motorcycle upright and centered during transport while reducing interference from exhaust systems and side cases.
Because the tie-down point is through the axle, CapStrap reduces the need to compress the suspension aggressively, helping protect suspension components during transport. The system includes the ratchet and strap and is designed for fast setup. The ABS strap material is made to help prevent scratching on painted surfaces and aluminum components.
