Fuel EX 8 is a confident and versatile trail bike built to get after it. It comes ready to rip with an Alpha NEXT Platinum frame, Fox performance suspension package with 145mm/150mm travel (rear, front), alloy Bontrager Line wheels, and a SRAM Eagle 70 transmission that keeps shifts smooth, even under load. Its topped off with 4-piston SRAM DB 8 hydraulic disc brakes to keep you stopping on a dime.

Adapt, rip, repeat

Only you can define your perfect trail bike — thats 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

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

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

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

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

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.
