The Top Fuel 9 Gen 4 is a full-suspension aluminum trail bike that confidently tackles steep climbs and remains unfazed on the descents. It combines all the benefits of a lightweight, robust aluminum frame with highly effective upgrades, such as the wireless SRAM GX Eagle AXS Transmission, hydraulic 4-piston disc brakes, and the FOX suspension package with 130 mm front and 120 mm rear travel.
