Acerbis 15L / 3.95 Gallon Fuel Tank for the 2026+ KTM EXC-F, XC-W and XCF-W

The Acerbis 3.95 Gallon High Capacity Fuel Tank is the ultimate upgrade for extending the range of your new-generation KTM motocross, cross-country, or enduro motorcycle. The factory KTM fuel tanks offer limited capacity, severely restricting your ability to tackle long Backcountry Discovery Routes (BDRs), deep woods loops, or extended hare scrambles without carrying auxiliary fuel bottles. This Acerbis tank directly replaces the OEM unit, significantly increasing your fuel range and eliminating trailside range anxiety.

Constructed from ultra-durable, extra-thick cross-linked polyethylene, this tank is engineered to take severe off-road impacts without puncturing or splitting. Despite the massive increase in fuel capacity, Acerbis meticulously designed the outer mold to maintain the narrow, ergonomic profile of the newest KTM chassis. It pushes the extra volume down low around the engine radiators, keeping the motorcycle's center of gravity optimized and ensuring your body positioning and cornering feel are not compromised.

Features:

• Extended Range: Expands your total fuel capacity to a massive 4.0 gallons (3.95 gal exact) for long-distance off-road capability.

• Slim Ergonomics: Pushes the additional fuel volume downward rather than outward, keeping the seat and knee junctions narrow for aggressive riding.

• Heavy-Duty Construction: Molded from extremely durable cross-linked polyethylene to survive crashes, tree strikes, and heavy trail abuse.

• EFI Compatible: Designed to seamlessly accept the factory KTM internal EFI fuel pump assembly.

• Two Color Options: Available in standard Black (2986850001) or a translucent Natural finish (2986850147).
