    Frequently Asked Questions

    What are the benefits of installing an aftermarket dirt bike gas tank?

    Aftermarket dirt bike gas tanks from brands like IMS and Clarke are designed to increase fuel capacity for long-distance trail riding and desert racing without compromising the bike's ergonomics. These tanks are typically made from durable cross-linked polyethylene, offering a lightweight and impact-resistant alternative to stock reservoirs that allows riders to stay on the trail longer between refuels.

    How do I choose the right oversize gas tank for my Honda or Yamaha dirt bike?

    Compatibility is determined by your specific year, make, and model, such as a Yamaha YZ250F or Honda CRF450R, to ensure a precise fit around the frame and radiators. You should also consider the tank shape; for example, IMS Desert Tanks often carry fuel lower to maintain a balanced center of gravity while increasing volume.

    What is the average capacity of an oversized desert tank for KTM and Husqvarna models?

    Standard factory tanks usually hold about 1.5 to 2 gallons, whereas oversized Safari or Acerbis tanks for models like the KTM 500 EXC or Husqvarna FE 501 can range from 3.1 to over 5 gallons. High-capacity tanks are essential for dual-sport riders who need the extra range to bridge the gap between remote gas stations during off-road excursions.

    Which brands make the most durable oversized fuel tanks for off-road racing?

    Industry leaders like Acerbis, IMS Products, and Clarke Manufacturing are the top choices for professional and amateur racers due to their proven track record in Baja and GNCC events. These brands utilize high-grade materials and precision molding to ensure their tanks withstand the vibrations and impacts common in aggressive off-road environments.

    Do I need to buy a new fuel pump or petcock when upgrading my dirt bike gas tank?

    Most oversized tanks are designed to reuse your OEM fuel pump or petcock, but some models may require a specific aftermarket valve like a Pingel high-flow petcock for maximum performance. Always verify if the tank includes a new gas cap and mounting hardware, as some Acerbis or Safari tanks use a proprietary cap style different from the stock factory unit.
