A carbon fiber tank cover for the KTM 690 replaces the stock plastic side panels in the tank area with lightweight, autoclave-cured carbon fiber — cutting weight and giving the bike's midsection a true motorsport finish. Bestem's KTM 690 carbon fiber tank side panels are a direct bolt-on for 2010–2018 KTM 690 SMC, SMC R, Enduro, Enduro R, and Rally models, mounting to the factory points with no drilling or modification.

Does the KTM 690 actually have a tank cover?

Yes — but with a quirk worth knowing before you order. On the 690 SMC R and Enduro R platform, the fuel tank is molded into the rear subframe and the fuel filler sits under the passenger seat. The panels riders call the "tank covers" sit up front, flanking the steering head, where they shroud the airbox and radiators. That's the plastic bodywork the carbon versions replace. So if you're searching for a KTM 690 tank cover, the correct part is a set of tank side panels — and that's exactly what Bestem builds for this bike.

One fitment note: these panels are shaped for the SMC/Enduro/Rally bodywork. The 690 Duke uses different shrouds, so Duke owners should look at Duke-specific carbon parts instead.

Which KTM 690 models do carbon tank side panels fit?

Bestem's tank side panels are catalogued for the 2010–2018 model range:

The panels follow the OEM panel geometry, so they seat against the stock mounting tabs and line up with the radiator shrouds and front fairing the way the factory plastic does.

What are Bestem carbon tank covers made from?

Every Bestem panel starts as 100% pre-preg Toray carbon fiber — the resin is precision-impregnated into the weave at the material stage, not brushed in by hand. The parts are laid into matched-metal molds and autoclave-cured under heat and pressure, an aerospace-grade process that fully consolidates the laminate and drives out voids. There is no wet-lay, no resin infusion, and no fiberglass backing in these parts.

This 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, then adds a superior UV-resistant coating on top. The visible surface is a clean 2×2 twill weave under a high-gloss clear coat.

Do carbon fiber tank covers 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, and the weave underneath starts to look milky. On a tank-area panel that sits in direct sunlight every ride, it happens fast with ordinary clear coats — most standard and OEM carbon coatings begin to amber after roughly 1,000 hours of UV exposure.

Bestem's panels carry a proprietary UV-resistant clear coat engineered specifically to protect the carbon weave, rated to approximately 3,000 hours of UV exposure — about 3× longer than OEM carbon coating before sun-ray yellowing appears. Because of that coating, every Bestem carbon part is backed by a lifetime warranty against UV (sun-ray) yellowing. For a supermoto or dual-sport that lives outdoors, at the track, and on the trailer, that's the difference between a panel that still looks new in five years and one that doesn't.

How much weight does a carbon tank cover save on the 690?

Autoclave-cured pre-preg carbon panels typically run 40–60% lighter than the ABS plastic they replace. On a pair of tank side panels the absolute gram savings are modest — but the 690 SMC R and Enduro R are bikes where riders count grams, and the panels are one piece of a full carbon swap. Just as relevant on a bike that gets dropped and leaned on: pre-preg carbon is significantly stiffer and more crack-resistant than thin stock plastic at the same panel thickness.

How do you install carbon tank side panels on a KTM 690?

Installation is a straightforward garage job:

Most riders finish both sides in 20–30 minutes with basic hand tools.

What other carbon parts complete the KTM 690?

The tank side panels pair naturally with Bestem's other 690 SMC/Enduro/Rally pieces, all built to the same pre-preg, autoclave-cured spec: the carbon fiber front fairing and the carbon fiber rear tail fairing cover the rest of the bike's bodywork in matching twill weave and gloss finish.

Why order KTM 690 carbon parts from Bestem USA?

Bestem has been manufacturing carbon fiber since 2005 — over 20 years of production experience — and supplies OEM carbon parts to car and motorcycle manufacturers, the same process discipline that goes into every aftermarket panel. All parts are stocked in Bestem's Atlanta, GA warehouse and ship daily, worldwide, with live phone support every business day if you want to confirm fitment before you order.

FAQ

Where is the fuel tank on a KTM 690 SMC R or Enduro R?

The fuel tank is integrated into the rear subframe under the seat, with the filler cap beneath the passenger seat. The front "tank" area is bodywork covering the airbox and radiators — that's what carbon tank side panels replace.

Do carbon fiber motorcycle parts turn yellow in the sun?

Standard clear coats do — most begin to amber after about 1,000 hours of UV exposure. Bestem's proprietary UV-resistant coating is rated to roughly 3,000 hours, about 3× longer than OEM coating, and every part carries a lifetime warranty against sun-ray (UV) yellowing.

Will these tank side panels fit a 2019 or newer KTM 690 SMC R?

The panels are catalogued for 2010–2018 KTM 690 SMC, Enduro, and Rally models. If you have a 2019+ bike, call Bestem during business hours to confirm fitment before ordering.

Are Bestem carbon parts pre-preg or wet-lay?

100% pre-preg Toray carbon fiber, autoclave-cured in matched-metal molds. No wet-lay, no resin infusion, no fiberglass core — the same aerospace-grade construction premium European carbon makers use.

How long does it take to install KTM 690 carbon tank side panels?

About 20–30 minutes with basic hand tools. The panels bolt to the factory mounting points; you just transfer the stock rubber grommets and hardware over.
