VM Racing Axial‑to‑Radial 78 mm Caliper Adapter – 300 mm Disc Ready, 100 mm/108 mm Radial Options for Honda CRF & Yamaha YZ/YZF - 100 mm - 300mm

Description

The VM Racing Axial‑to‑Radial 78 mm Caliper Adapter transforms your motocross or enduro bike into a supermoto machine. Designed for bikes with a 78 mm axial mount (Honda CRF 2009‑2025 and Yamaha YZ/YZF 2013‑2025), this adapter lets you install a radial brake caliper while retaining your stock fork legs. It’s CNC‑machined from high‑grade aluminium and completely redesigned to accommodate 300 mm supermoto front discs, so you get improved braking without switching to an expensive steering stem with a wider spacing. The adapter’s offset design moves the caliper away from the disc’s standard axis, clearing spokes and allowing radial caliper installation without grinding the caliper body or changing triple clamps. For proper alignment, VM Racing recommends fitting a compatible disc flange (sold separately) to match your wheel and disc. The bracket is offered with two radial mount options—100 mm for calipers with a 30 mm offset and 108 mm for calipers with a 22.5 mm offset—to suit different radial calipers. Each kit includes axial/radial mounting bolts and radial‑spacing bushings. For detailed installation instructions, refer to VM Racing’s downloadable guide.
