GBrakes Oversize Wave Front Brake Rotor - 12.5in Harley-Davidson

A 12.5 inch full floating Wave rotor that bolts to the stock hub pattern and adds pad contact area without a wheel change.

Going oversize is the cheapest real braking gain available on a heavy bike. A larger rotor gives the caliper more leverage and more surface to dump heat into, so the lever holds firm through repeated hard stops instead of going long. This one keeps the stock hub pattern, so it bolts on rather than requiring a new wheel.

Features of the Oversize Wave Front Brake Rotor

• Full floating oversize rotor design
• Bolt on design that works with the stock hub pattern
• Made from high carbon 420 stainless steel
• Laser cut, never stamped, and double disc parallel ground for perfect flatness
• Heat treated for each specific application
• Non directional design, so it can be used on the right or the left

Fitment

'00-'25 Big Twin, '00-'07 XL, '07 VRSC, '21-'25 RA1250/S/ST (except H-D Trike)

Note: Brake caliper relocation brackets and radial caliper mounts are sold separately and are required for an oversize rotor.

About GBrakes

GBrakes is the brand of Giocar America, the company that built and sold Galfer USA product from 1992 until 2025. Same family, same Milesi engineering lineage, now developing its own braking systems. If you have run Galfer rotors or pads on a Harley-Davidson before, this is the line that succeeded them.

Works With

This is the successor to the Galfer Oversize Wave Front Brake Rotors we also stock, so if you have run those before the fitment carries straight over.
