The 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 130 mm of front and 120 mm 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 group set that gives you everything you need to rip in an economical package.


It's right for you if...

You want to dive into a full suspension rig and want a light, yet capable alloy ride to get you there. Cost is an important factor, and you don't mind upgrading some parts over time. You want to ride a variety of trails, from smooth cross-country to more rugged all-mountain and you need a versatile bike that stays efficient on long climbs without sacrificing confidence on descents.

 

The tech you get

An Alpha Platinum Aluminium frame with a 4-way Mino Link for adjusting geometry and leverage rate. A 130 mm RockShox Recon Silver RL fork with SoloAir spring, Motion Control damper and lockout, plus 120 mm of rear travel with an X-Fusion Pro 2 shock with a 2-position damper. It's topped off with a Shimano Deore 12-speed group set, hydraulic disc brakes, a TranzX dropper post and Tubeless Ready Bontrager Line TLR 30 wheels.

 

The final word

The Top Fuel 5 Gen 4 is a versatile trail bike that finds the balance between efficiency, capability and budget. Its lightweight alloy frame packs in tons of adjustment, thanks to the 4-way Mino Link, with plenty of internal storage for stashing essentials on the ride. An economical component package is ready to hit the trail now and gives you room for upgrades later.
