The Top Fuel 9 Gen 4 is a full-suspension aluminum trail bike that handles steep climbs confidently and remains steady on descents. It combines all the advantages of a lightweight, durable 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 featuring 130 mm of travel in the front and 120 mm in the rear.
