  • Adapt, rip, repeat

    Adapt, rip, repeat

    Only you can define your perfect trail bike — that's why Fuel is available in three adjustability-packed configurations. Get do-it-all capability with EX, go pop-happy with MX, or charge through it all with LX.

  • Adjustable leverage rate

    Adjustable leverage rate

    Want more bottom-out resistance without giving up small-bump sensitivity? Flip the chip in the lower shock mount for a more progressive leverage rate.

  • Zero stack integrated headset

    Zero stack integrated headset

    With a ZS standard headset, you've got tons of options for aftermarket upgrades, including angle adjust or anodized colors.

  • Storage and accessory mounts

    Storage and accessory mounts

    Stash ride essentials with in-frame storage on all Fuel models — both carbon and alloy. Plus, top tube accessory mounts let you load up even more.

  • Fresh frame design

    Fresh frame design

    Fuel's new frame gives you tons of room for long dropper posts, bigger shocks, frame bags, and more.

  • Active Braking Pivot

    Active Braking Pivot

    Active Braking Pivot allows our engineers to tune how the suspension reacts to acceleration and braking forces independently. That means you get more confident control when you need it most.

  • Transition to transmission

    Transition to transmission

    SRAM Eagle T-Type transmission mounts directly to the frame, skipping that pesky derailleur hanger of yesteryear. This makes for a more robust system that's not only cleaner looking, it's also more precise under load, and easier to set up.

  • A better way to produce aluminum

    A better way to produce aluminum

    Starting in 2024, we began removing high-emission aluminum from our manufacturing and replacing it with low-emission aluminum made with renewable energy. By October 2025, nearly every alloy bike we make - this one included - had made the switch, driving a major drop in our footprint.

Overview

Fuel MX 9 Eagle 90 is a playful trail bike made for hunting down side hits. Its Alpha NEXT Platinum aluminum frame it paired with a Fox Factory suspension package (150mm rear, 160mm front) and MX wheels for a ride that's flickable and zippy. It comes ready to rip with a fuss-free SRAM Eagle 90 mechanical transmission that keeps shifts smooth under load and SRAM Maven Bronze 4-piston brakes for stopping power.
