The Top Fuel 9 Gen 4 is a fully suspended aluminum trail bike that excels in climbing steep ascents with ease and remains unfazed on the way down. It integrates 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 front travel and 120 mm of rear travel.
