Function and Benefits
The primary function of this tank is to replace the stock fuel tank with a larger capacity unit, extending the range for trail riding, enduro, or desert racing. It retains the original mounting points and ergonomics, so the rider's position and bike handling are not compromised. The natural translucent color allows easy visual fuel level checking.
Vehicle Fitment
This tank is designed for KTM 125 SX (2016-2018), 150 SX (2016-2018), 150 XC-W (E-Start) (2017-2019), 250 SX (2017-2018), 250 XC (2017-2018), 250 XC-W (E-Start) (2017-2018), 300 XC (2017-2018), and 300 XC-W (E-Start) (2017-2018). Always verify compatibility with your specific model and year. Some listings note that this tank is not for California emissions models.
Construction and Durability
The tank is rotationally molded from cross-linked polyethylene, a material chosen for its impact and abrasion resistance. It is thicker than stock for added durability in off-road conditions. The natural finish is translucent, and the tank is compatible with Acerbis' MDR gas cap (sold separately) for quick refueling.
Installation Overview
Installation is a direct bolt-on replacement using the included mounting kit and hardware. The tank comes with a gas cap and vent hose. For carbureted models, the stock petcock and fuel lines can be reused; some applications may require Y-fittings or additional fuel line routing. EFI models require the stock fuel pump to be transferred (not included). Always follow the manufacturer's instructions.
