Stealth Motorcycle Caliper

Don’t hide your custom wheels! Show them off with the new Stealth™ brake system’s revolutionary design.

For 30 years, Wilwood Disc Brakes has engineered and manufactured the innovative brake systems that define the custom aftermarket and dominate professional motorsports in the USA at such legendary racetracks as Daytona and The Brickyard. Wilwood’s crossover technology has now culminated into Stealth, the virtually invisible motorcycle brake system that disappears into your front wheel.*

Large 18.75” diameter rotor for great stopping power. Show polished billet aluminum components. The Stealth system bolts directly to 41mm Wide Glide front ends with stock fender mounts. The system provides unlimited wheel design possibilities, and there's no rotor to hide your custom wheels. Works with or without a fender, and provides stopping power like nothing else.
