• 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.

The Top Fuel 9 Gen 4 is an alloy trail bike that's ready to billy-goat up long climbs and rip back to the bottom for another lap. It gives you the rugged benefits of a lightweight aluminium frame, plus the upgrades you crave, like fully wireless shifting from SRAM's GX Eagle AXS transmission, 4-piston hydraulic brakes and a 120 mm/130 mm FOX suspension package.
