Description
Top Fuel 8 is a nimble alloy trail bike that strikes a balance between quick climbing efficiency and descending confidence. With 140mm front and 130mm rear travel, it rips over rocks and roots without sacrificing power on ascents.
It's built from lightweight Alpha Platinum Aluminum that helps save your budget for bike trips, but packs in upgrades where they matter, like a 12-speed Eagle 70 drivetrain and a Fox Rhythm 34 fork. Make the Top Fuel yours Opt for light parts and a 120 mm fork for a featherweight Top Fuel, or a 140 mm fork and longer-stroke 130 mm rear shock for extra versatility.
Room for a longer dropper and MX wheels lets you customise the Top Fuel into an ultimate playful trail whip. 4-way Mino Link Easily adjust the suspension and geometry four different ways for where and how you ride.
At the flip of a coin, you can ride with more or less progressive suspension and tweak your geometry for a slacker head tube and lower BB, or steeper head tube and higher BB. New internal storage with new BITS bags New internal frame storage bags make it easy to ditch the pack and still carry your ride essentials.
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.
A better way to produce aluminium Starting in 2024, we began removing high-emission aluminium from our manufacturing and replacing it with low-emission aluminium 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.
