Brake Rotors

Motorcycle Brake Rotors

That Handle Real Heat

GBrakes® has over 70 years of accumulated brake knowledge and expertise. We offer a variety of round and Wave® rotors for optimal performance and braking power for VTWIN, Sport/Street,; Dirt/Dual sport bikes enthusiasts. Ask us about our VTWIN custom rotors, ideal for unique bike builds like Harley-Davidson® , Indian® , Honda® , Yamaha® , Suzuki® , Kawasaki® , Ducati® , KTM®, and projects that require that special added touch of personalization and upgrade in performance.

Each are engineered in the USA, and manufactured in Europe.

Gbrakes® carries performance-grade motorcycle brake rotors built for real braking demands. These are selected for material, design, and heat management. We’ve got clearly labeled line ends so you know exactly where each hose mounts, no guessing, no mix-ups. Proudly made in the USA.

Yours may look fine until they pulse, or disappear under heavy braking. Our replacement brake rotors are vetted against high standards: thermal stability, material integrity, and performance endurance.

Material Quality

We use 420 high carbon virgin stainless steel

  • This steel maintains a high degree of hardness and possesses good corrosion resistance, grinding properties, and moderate tensile strength and wear resistance.

Durability

Heat treatment application

  • Heat treatment ensures hardness while preserving the right amount of flex, preventing cracking over longer periods of time.

Precision

Laser-cut, never stamped

  • Laser cutting is non-contact, precise, and accurate. When the surface of the steel is stamped, it bends the material, leaving a memory imprint that increases the probability of warping under high heat and performance conditions.

Symmetry

Parallel double disc grinding process

  • Double disc grinding is a special method employed that simultaneously grinds two sides of the rotor with a focus on achieving ideal flatness and parallelism for a tight tolerance surface finish.

Technology

We apply a special Cryo-Tech™ treatment to our rotors

  • Cryo-Tech™ Treatment is a special process that our laser-cut stainless-steel rotors go through to improve quality and longevity. The benefit of Cryo-Tech® is that it improves hardness by transforming retained austenite into martensite, which is a harder phase of steel, thus improving durability and longevity.

Tech Support

U.S.-based live technical support

  • Our technical experts are available via phone, email, or chat.

Warranty

Rotors come with a 6-month limited warranty (proof of purchase required)

  • All warranty products are individually inspected in-house by one of our experienced and qualified technicians and inspected within 24 hours of receiving the package.
  • All warranty issues are handled directly through GBrakes®, regardless of what distributor you purchased from.

Pioneering

GBrakes® coined the industry-wide recognized term Wave® as a style of rotor and owns the mark

  • Wave references a rotor design known for lightweight performance, the ability to run cooler, and improved heat dissipation with less fade for performance enhancement. If it claims Wave but is not GBrakes®, it’s not a Wave® rotor.

Rotor Materials, Designs & What to Know

Your rotor choice feeds directly into bite, heat resistance, and overall braking feel. Here's how to get it right.
Fixed vs Floating Brake Rotors
Fixed vs Floating Brake Rotors
  • Fixed brake rotors (one-piece) : bolt solid to the hub, simple and durable. Great for lighter street bikes or cruisers with mild braking needs. But under heat, they expand unevenly, risking warping.
  • Floating rotors (two-piece) : use carrier mounts and bobbins to allow the braking disc to shift independently of the hub. That float keeps the disc centered under heat and load, reducing warping and improving performance consistency. Also helps reduce heat transfer to the wheel hub and bearings
High Carbon vs Stainless Steel Rotors
  • High-carbon brake rotors : resist thermal-cracking and disperse heat more efficiently than plain steel . They’re pricier, but they resist blueing and distortion under stress.
  • Stainless steel rotors : offer corrosion resistance and everyday reliability. Ideal for commuting or moderate riding—but on aggressive platforms, they can suffer under sustained heat.
High Carbon vs Stainless Steel Rotors
Vented vs Solid & Drilled Discs
  • These can have slots, waves, or drilled patterns, but this isn’t just for looks. Drilled holes help clear gas, water, and dust, improving wet braking by breaking fluid film. Unlike cars, most bikes don’t need vented channels due to airflow exposure .
  • Wavy or floating-disc designs optimize mass closer to the hub, reducing overall inertia and improving weight distribution .
Front vs Rear Brake Rotors
  • The front brake rotors do most of the stopping, requiring larger size, higher-quality materials, and consistent performance under repetitive braking. The rear ones are smaller, handle less heat, and focus on stability and lugging, especially under load (cruisers, touring).

What Are Brake Discs Made Of & How It Matters

Most use grey cast iron or high‑carbon steel alloys for their balance of durability and thermal properties. High-carbon modifies those alloys to resist warping and reduce vibration . Stainless steel offers corrosion protection but needs to be high‑quality to avoid heat fade.

Signs You Need New Rotors

  • Pulsation under braking = likely warped disc
  • Blue or dark discoloration = heat-soaked rotor
  • Cracks or surface scoring = replace now
  • Rotor surface uneven = affecting pad contact

Riding on faded or warped ones are not only unsafe, it ruins pad performance and feedback.
