A carbon fiber tank cover for the Kawasaki Ninja H2 replaces the painted factory tank-side panels with lightweight pre-preg carbon fiber pieces that bolt onto the factory mounting points. Bestem manufactures 100% pre-preg Toray carbon tank trim and knee grip panels for the 2015–2018 Ninja H2 and H2R, autoclave-cured and finished with a proprietary UV-resistant coating backed by a lifetime warranty against sun-ray yellowing.
What counts as a "tank cover" on the Ninja H2?
On most bikes, a tank cover is a single shell that slips over the fuel tank. The H2 is different: its steel tank is framed by separate painted trim panels — the side covers that carry the body lines and the knee grip panels where your legs contact the bike under braking. Those are the pieces riders mean when they search for an H2 carbon tank cover, and they're the pieces that take the most abuse from leathers, knee sliders, and boot buckles.
Swapping them to carbon fiber does three things at once: it drops weight off the highest point of the chassis, it protects the tank edges from scuffs, and it matches the H2's factory carbon accents.
Which carbon tank panels fit the 2015–2018 Ninja H2 and H2R?
Two parts make up the tank-area conversion:
- Gas Tank Side Trim Cover Panels (SKU CBKA-H2-TSP-T) — the pair of side covers that frame the tank, laid in a 2x2 twill weave.
- Gas Tank Side Trim Knee Grip Cowlings (SKU CBKA-H2-KFI-T) — the lower panels your knees clamp under hard braking, also in twill.
Both are molded as direct replacements using the factory mounting points, so installation is a bolt-on swap with basic hand tools — no drilling, no trimming. The same tooling covers later H2 model years listed on each product page.
How is Bestem carbon fiber made?
Every Bestem H2 panel starts as 100% pre-preg Toray carbon fiber — fabric pre-impregnated with a precisely measured resin system, the same aerospace-grade raw material used in motorsport and aviation. The layup is compressed in matched-metal molds and cured in an autoclave under heat and pressure, which forces out voids and excess resin that hand-laid, wet-lay, or resin-infused parts can't avoid.
This is the same autoclave-plus-pre-preg construction that premium European carbon makers such as Ilmberger built their reputation on. Bestem uses that same technology, then adds a superior UV-resistant clear coat on top. We've been manufacturing carbon fiber since 2005 — over 20 years — and we supply OEM carbon parts to car and motorcycle manufacturers, so the panels you bolt onto your H2 come off the same production discipline as factory-supplied parts.
Do carbon fiber tank covers turn yellow in the sun?
Yes — sun-ray (UV) yellowing is the single most common defect riders see on carbon fiber fairings. The clear coat ambers and clouds over time, and tank panels cop the worst of it because they sit in direct sun on every ride and every day parked outside. On standard or OEM clear coat, expect visible yellowing after roughly 1,000 hours of UV exposure.
Bestem's proprietary UV-resistant coating protects the weave for approximately 3,000 hours of UV exposure — about 3× longer than standard OEM clear coat. That's why every Bestem carbon part carries a lifetime warranty against sun-ray yellowing.
For a bike like the H2, whose whole aesthetic depends on deep, glass-clear carbon against black chrome paint, that coating is the difference between panels that still look new in five years and panels that amber out in two seasons.
How much weight do carbon tank panels save?
Pre-preg, autoclave-cured panels are substantially lighter than the painted OEM pieces they replace because the autoclave process removes excess resin — resin is weight with no structural value. On a supercharged machine that sits around 525 lb wet, pulling mass off the top of the tank area also marginally lowers the center of gravity. The bigger day-to-day gains are durability and looks, but the weight saving is real and free.
What other carbon parts complete the H2?
Most H2 owners who convert the tank area continue across the rest of the bodywork. Common next steps from the same twill-weave line:
- Upper Front Nose Air Intake Ram Fairing (SKU CBKA-H2-AIC-T) — the ram-air nose piece that defines the H2's face.
- Rear Tire Hugger Chain Guard (SKU CBKA-H2-HGR-T) — protects the shock and swingarm while finishing the rear end.

FAQ
Will these tank panels fit the Ninja H2R as well as the H2?
Yes. Both the side trim covers (CBKA-H2-TSP-T) and knee grip cowlings (CBKA-H2-KFI-T) fit the 2015–2018 Ninja H2 and H2R, with later model years covered on the product pages.
Is a carbon tank cover a full tank replacement?
No. These are bodywork panels that replace the painted trim around the H2's steel fuel tank — the tank itself stays in place. Installation is a bolt-on swap using the factory mounting points.
Will the carbon fiber turn yellow over time?
Not with Bestem's coating. Our proprietary UV-resistant clear is rated to roughly 3,000 hours of UV exposure versus about 1,000 hours for standard OEM clear coat, and every part carries a lifetime warranty against sun-ray yellowing.
What weave and finish do the H2 tank panels use?
Both panels are laid in a 2x2 twill weave — the pattern that matches Kawasaki's factory carbon accents — in 100% pre-preg Toray carbon, autoclave-cured in matched-metal molds.
