A carbon fiber sprocket cover for the Suzuki Hayabusa replaces the factory guard over the front sprocket with a part that is far more rigid, holds its finish dramatically longer in the sun, and shrugs off the chain lube and road debris that age painted plastic. Bestem's version for the 2022+ GSX1300RR is 100% pre-preg Toray carbon fiber, autoclave-cured in matched-metal molds, and backed by a lifetime warranty against UV yellowing.
What does a sprocket cover do on the Suzuki Hayabusa?
The sprocket cover sits over the front (countershaft) sprocket on the left side of the bike. On a 1,340cc machine built to run at serious speed, it has real work to do:
- Shields the front sprocket and chain from road debris, water, and grit
- Contains chain lube fling before it reaches the swingarm, wheel, and your boots
- Keeps laces, straps, and riding gear clear of the chain run
- Adds a layer of protection for the engine cases in the event of a chain failure
Because it sits low and forward, the cover takes constant abuse from lube overspray and kicked-up debris. That is exactly where carbon fiber earns its keep: a rigid composite shell resists the flexing, scuffing, and finish chalking that the stock plastic piece accumulates over seasons of riding.
Which Hayabusa years does this carbon fiber sprocket cover fit?
The 2022 Suzuki Hayabusa GSX1300RR Carbon Fiber Sprocket Cover in twill weave (SKU CBSU-BUSA22-SPC-T) is molded specifically for the third-generation Hayabusa — the GSX1300RR introduced for 2021 and sold as the 2022 Hayabusa in the US market. Mounting points and contours are year-specific, so riders on Gen 1 (1999–2007) or Gen 2 (2008–2020) bikes should choose parts listed for those model years rather than attempting to adapt a Gen 3 cover.
How is Bestem's carbon fiber made?
Every Bestem carbon part — including this sprocket cover — is built the same way, and the process is the difference between real structural carbon and cosmetic carbon-look parts:
- 100% pre-preg Toray carbon fiber — the resin is precisely impregnated into the weave at the factory, not brushed on by hand
- Autoclave-cured under heat and pressure, which eliminates voids and produces a dense, consistent laminate
- Metal-molded using matched-metal tooling, so every cover comes out with identical geometry and mounting holes that line up with the factory points
This is an aerospace-grade process — not wet-lay, hand-laid, or resin-infused. It is the same autoclave plus 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 on top. The twill weave on this cover matches the pattern used across the rest of the Bestem Hayabusa line, so the finish stays consistent if you are bolting on more than one piece.
Do carbon fiber sprocket covers turn yellow in the sun?
Yes — sun-ray (UV) yellowing is the single most common defect riders see on carbon fiber parts. The clear coat ambers and clouds, and on standard OEM-spec clear coat it typically starts after roughly 1,000 hours of UV exposure. A sprocket cover sits in direct sunlight whenever the bike is parked outside, so coating quality matters as much here as on any fairing panel.
Bestem applies a proprietary UV-resistant clear coat rated to approximately 3,000 hours of UV exposure — about 3x the roughly 1,000-hour lifespan of standard OEM clear coat.
Because of that coating, this sprocket cover carries a lifetime warranty against sun-ray (UV) yellowing. The weave you see on install day is the weave you will see years later.
How do you install a sprocket cover on the Hayabusa?
Installation is a straightforward swap. Because the cover is formed in matched-metal tooling from the factory part's geometry, it mounts to the stock points with the factory fasteners — no trimming, drilling, or modification. Most riders complete the job with basic hand tools in a few minutes per side. As with any bodywork, start all fasteners before tightening any of them fully.
Why order from Bestem USA?
Bestem has been manufacturing carbon fiber since 2005 — more than 20 years — and supplies OEM carbon parts to car and motorcycle manufacturers, which is the same production discipline that goes into every aftermarket piece. All parts are stocked in Bestem's Atlanta, GA warehouse and ship daily worldwide, with live phone support every business day from staff who know the product line.
Riders building out a full carbon package on the Gen 3 Hayabusa often pair the sprocket cover with the matching twill carbon fiber tank cover and carbon fiber front fender — same weave, same coating, same warranty.
FAQ
Will this sprocket cover fit my 2008–2017 Hayabusa?
No. This cover (SKU CBSU-BUSA22-SPC-T) is molded for the third-generation GSX1300RR, 2021 onward — the 2022+ Hayabusa in the US. Gen 1 and Gen 2 bikes use different mounting geometry, so choose parts listed for your specific model year.
Is this real carbon fiber or a carbon-look overlay?
It is 100% pre-preg Toray carbon fiber through and through — autoclave-cured and formed in metal molds. There is no fiberglass core, no hydro-dipped film, and no printed pattern.
How long before the carbon turns yellow in the sun?
Standard clear coats typically begin to amber after roughly 1,000 hours of UV exposure. Bestem's proprietary UV-resistant coating is rated to about 3,000 hours — roughly 3x longer — and the cover carries a lifetime warranty against sun-ray yellowing.
How do I clean and care for the sprocket cover?
Wash with mild soap and water and dry with a microfiber towel. Avoid abrasive compounds on the clear coat, and wipe off chain lube overspray during regular chain maintenance. A clear-coat-safe wax or sealant is fine to use.
