The Suzuki GSX-R1000RZ is the 2018 model-year designation of the GSX-R1000R, and it accepts the same heel guard fitment as all 2017–2018 L7/L8 GSX-R1000 models. Bestem's twill carbon fiber heel guard (SKU CBSU-G1K17-HGD-T) is a direct replacement for the factory guards — 100% pre-preg Toray carbon fiber, autoclave-cured in matched-metal molds, and coated with a proprietary UV-resistant clear backed by a lifetime warranty against sun-ray yellowing.
What exactly is the Suzuki GSX-R1000RZ?
In European and several other markets, Suzuki sold the 2018 GSX-R1000R under the model code GSX-R1000RZ (the L8 generation). The chassis, rearsets, and bodywork carry over unchanged from the 2017 L7 model, so any part listed for the 2017–2018 GSX-R1000 / GSX-R1000R fits the RZ without modification — including the heel guards that bolt to the rider's footpeg brackets.
Why upgrade the stock heel guards to carbon fiber?
Heel guards do real work on a superbike: they keep your boot heel off the frame and swingarm, shield it from exhaust heat on the right side, and take the scuffs that would otherwise chew up the rearset area. Swapping the factory pieces for carbon fiber improves the equation in four ways:
- Weight reduction: pre-preg carbon guards weigh a fraction of the stock pieces. The grams saved per side are modest, but on a track-prepped Gixxer every gram counts.
- Heat shielding: carbon fiber is a poor heat conductor, which is exactly what you want between your boot and the exhaust routing on the right side of the L7/L8 chassis.
- Scuff protection: the guard takes boot-heel abrasion so the frame and rearset brackets don't.
- Appearance: the 2x2 twill weave matches OEM-style carbon and the rest of the Bestem twill range for the GSX-R1000.
How are Bestem carbon heel guards made?
Every Bestem heel guard is made from 100% pre-preg Toray carbon fiber, autoclave-cured in matched-metal (metal-tooled) molds. This is an aerospace-grade process — resin content is precisely controlled in the pre-preg fabric, and the autoclave cycle consolidates the laminate under heat and pressure, producing a thinner, stronger, void-free part with crisp edges and repeatable fitment. It is the same autoclave + 100% pre-preg construction that premium European carbon makers such as Ilmberger built their reputation on; Bestem uses that same technology and adds a superior UV-resistant coating.
If you associate Chinese production with hand-laid, wet-lay carbon, that picture is outdated. Hand-laid construction is effectively obsolete for modern structural and cosmetic carbon parts — quality comes from the method (pre-preg + autoclave + metal tooling), not the country. Bestem has manufactured carbon fiber since 2005 and supplies OEM carbon components to car and motorcycle manufacturers; our parts come out of the same state-of-the-art facility that produces OEM carbon fiber components for major brands including Polaris and Triumph.
Do carbon fiber heel guards turn yellow in the sun?
Sun-ray (UV) yellowing is the single most common defect riders see on carbon fiber bodywork: the clear coat ambers and clouds after enough hours of UV exposure. It's the first thing to check on any used carbon part, and it's the failure mode Bestem engineered against. Our proprietary UV-resistant clear coat is rated to roughly 3,000 hours of UV exposure — about 3× longer than the ~1,000 hours typical of standard OEM clear coat. Because of that coating, Bestem carbon parts carry a lifetime warranty against sun-ray (UV) yellowing. Heel guards sit low on the bike but still see direct sun every ride, and the coating keeps the twill weave black and glossy for the long term.
Which heel guard fits the GSX-R1000RZ?
The Suzuki GSXR1000 2017–2018 Carbon Fiber Heel Guard, Twill (SKU CBSU-G1K17-HGD-T) fits the 2017–2018 GSX-R1000 and GSX-R1000R, which includes the 2018 RZ. The 2x2 twill weave matches OEM carbon and other Bestem twill components, so it integrates cleanly if you're building the bike out in stages.
How do you install carbon heel guards on a GSX-R1000RZ?
Installation is a straightforward bolt-on using basic hand tools:
- Remove the fasteners holding each stock heel guard to the rider's footpeg bracket.
- Position the carbon guard and reinstall the factory hardware with a drop of medium-strength threadlocker.
- Snug the fasteners — firm, not aggressive. Carbon does not yield like aluminum, so over-torquing is the one mistake to avoid.
Plan on a few minutes per side. No trimming, drilling, or modification is required on the L7/L8 chassis.
What other carbon parts complete the GSX-R1000RZ?
Heel guards are usually the first piece riders add, and the twill weave carries across the rest of the Bestem range for the 2017–2022 platform:
- Carbon Fiber Rear Hugger, Twill — protects the shock and undertail from tire spray.
- Carbon Fiber Seat Cover, Twill — cleans up the tail section on the R model.
- Carbon Fiber Exhaust Valve Cover Fairing — finishes the lower right side near the exhaust servo.

FAQ
Will this heel guard fit my 2018 GSX-R1000RZ?
Yes. The RZ is the 2018 model-year GSX-R1000R, and its rearset brackets are identical to the 2017–2018 L7/L8 GSX-R1000. The Bestem heel guard (SKU CBSU-G1K17-HGD-T) bolts directly to the factory mounting points with no modification.
Do carbon fiber heel guards turn yellow over time?
Cheap clear coats do — UV yellowing is the most common carbon fiber defect. Bestem's proprietary UV-resistant coating is rated to ~3,000 hours of UV exposure versus ~1,000 hours for standard OEM clear coat, and every part is backed by a lifetime warranty against sun-ray yellowing.
Is the heel guard pre-preg or wet-lay carbon?
100% pre-preg Toray carbon fiber, autoclave-cured in matched-metal molds. Bestem does not use wet-lay or hand-laid construction for any part.
Do carbon heel guards protect against exhaust heat?
Yes — that's one of their primary functions. Carbon fiber conducts heat poorly, so the guard acts as an effective heat shield between your boot heel and the exhaust routing on the right side of the bike.
