The Moto-Master Front Caliper Adapter (211037) is an essential precision component when upgrading your Yamaha dirt bike's front braking system. Designed specifically for Yamaha YZ and WR models, this adapter bracket safely and precisely relocates the original factory brake caliper outward to perfectly accommodate a 260mm front brake rotor. By accurately extending the caliper position, it ensures full brake pad-to-rotor contact, maximizing your stopping power without requiring a complete aftermarket caliper replacement.
Manufactured in The Netherlands from lightweight 6082 billet aircraft-grade aluminum and CNC-machined for exact tolerances, this bracket provides a rigid, flex-free mount that stands up to the heavy demands of motocross and off-road racing. The adapter is finished in a durable black anodized coating to prevent corrosion and maintain a factory racing aesthetic while keeping unsprung weight at the front wheel to an absolute minimum.
Oversize Rotor Upgrade: Relocates the stock OEM front brake caliper to perfectly accommodate a 260mm oversize front brake disc.
Billet Aluminum Construction: CNC-machined from high-strength 6082 aircraft-grade billet aluminum, eliminating flex under heavy braking.
Lightweight Design: Intentionally engineered with strategically machined pockets to keep unsprung weight as low as possible.
Direct Bolt-On: Seamless installation utilizing the original factory mounting points; no custom fabrication or spacers required.
Durable Finish: Black anodized coating protects the aluminum from corrosion, harsh cleaning chemicals, and trail debris.

Rotor Requirement: This bracket is strictly designed for use with 260mm front brake rotors. It will not work with standard OEM 250mm rotors or larger 270mm or 320mm supermoto setups.
Why 260mm:Many older Yamaha YZ and WR models came from the factory equipped with standard 250mm front rotors. Upgrading to a 260mm rotor provides a noticeable increase in braking leverage and heat dissipation without adding the extra weight or grabby initial bite sometimes associated with massive 270mm systems. This specific adapter (211037) allows you to retain your reliable factory Nissin caliper while properly aligning it with the new 260mm disc.
Hardware and Threadlocker: When installing caliper adapter brackets, always inspect the threads of your factory mounting bolts for wear or stretching. Clean the bolts thoroughly and apply medium-strength (blue) STUCK NUTZ threadlocker before tightening them to your factory service manual's torque specifications. The front brake is your most critical safety component; never leave these bolts loose.
