• 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 9.9 XTR Gen 4 is a lightweight carbon trail bike built to rip up climbs and stay playful on descents. It gives you the confidence you want through roots and rocks thanks to a 120 mm/130 mm RockShox suspension package with a Pike Ultimate fork and Deluxe Ultimate shock. Plus, you get clean shifts from a premium 12-speed Shimano XTR drivetrain.
