Top Fuel 5 Gen 4 is a nimble alloy trail bike that's ready to hammer up climbs and hold its own on descents – all without breaking the bank.

It offers 130mm of front and 120mm of rear suspension that gives you just enough squish to soak up chatter without draining your power on all-day pedal fests.

It comes equipped with a RockShox suspension package and Shimano Deore groupset that gives you everything you need to rip in an economical package.

  • Carry-On, But For Your Bike: Top Fuel’s new storage system is easier to use with a bigger opening, more secure seal, and all-new BITS bag system. Carry your essentials on your bike, not your body.

  • Room For Bigger Suspension And Longer Dropper Post: Top Fuel Gen 4 is more upgrade-ready than ever, with room for bigger 140mm forks and longer-stroke shocks for up to 130mm of rear travel, plus room for extra-long dropper posts.

  • Tubeless Out Of The Box: All Top Fuel Gen 4 models are tubeless and ready to go out of the box. Sealant, valves, and rim strips included.
