Top Fuel 8 Gen 4

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.

Technology

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.
