The Top Fuel 8 Gen 4 is a nimble alloy trail bike that strikes a balance between quick climbing efficiency and descending confidence. It packs in a versatile 130 mm front and 120 mm rear travel for ripping over rocks and roots without sacrificing power on ascents. It's built from lightweight Alpha Platinum Aluminium that helps save your budget for bike trips, but packs in upgrades where they matter, like a 12-speed Shimano XT and SLX drivetrain, and a Fox Rhythm 34 fork.
You want an alloy full suspension that's ready to rip. You like to ride everything from cross-country hot laps to all-mountain adventures, and you need a bike that's light, versatile and confident. You've got an appreciation for the durability of aluminium, but want upgrades where they matter, like your drivetrain and suspension.
An Alpha Platinum Aluminium frame equipped with a 4-way Mino Link lower shock mount for tweaking geometry and suspension leverage rate. A 130 mm FOX Rhythm 34 fork with Float EVOL air spring and GRIP damper, plus 120 mm of rear travel from a FOX Performance Float shock with a 3-position damper. It's topped off with a Shimano XT/SLX 12-speed group set, hydraulic disc brakes, a Bontrager Line dropper post and Tubeless Ready Bontrager Line Comp 30 wheels.
The Top Fuel 8 Gen 4 is ready to cut loose from all-day climbs to rooty descents. It balances capability and efficiency, with just enough travel to keep the ride smooth without eating up your pedalling power. It gives you the perfect blend of affordability, with a rugged alloy frame and upgrades where they matter, like the Shimano XT/SLX drivetrain.
- Its lightweight frame and versatile geometry make it the perfect choice for all kinds of rides and all kinds of riders
- The 4-way Mino Link makes it easy to adjust your geometry or leverage rate for how and where you want to ride
- You get a sweet balance of price and performance with upgraded components and a rugged alloy frame
- The Alpha Platinum Aluminium frame is robust, yet light, and packs in updated internal frame storage for easy access to gear and snacks
- It's more upgrade-ready than ever, with room for bigger 140 mm forks and longer-stroke shocks for up to 130 mm of rear travel, plus room for extra-long dropper posts
Make the Top Fuel yours
Opt for light parts and a 120 mm fork for a featherweight Top Fuel, or a 140 mm fork and longer-stroke 130 mm rear shock for extra versatility. Room for a longer dropper and MX wheels lets you customise the Top Fuel into an ultimate playful trail whip.
4-way Mino Link
Easily adjust the suspension and geometry four different ways for where and how you ride. At the flip of a coin, you can ride with more or less progressive suspension and tweak your geometry for a slacker head tube and lower BB, or steeper head tube and higher BB.
New internal storage with new BITS bags
New internal frame storage bags make it easy to ditch the pack and still carry your ride essentials.
Active Braking Pivot
Active Braking Pivot allows our engineers to tune how the suspension reacts to acceleration and braking forces independently. That means you get more confident control when you need it most.
Shimano XT
Shimano XT is the original mountain bike groupset and trusted by generations of mountain bikers around the world. Whatever the trail, wherever you ride, XT is your solution for mountain biking today. Reliable shifting. Superior braking. Intuitive maintenance. XT is the high performance workhorse you can count on.
Don't forget your pedals
This bike doesn't come with pedals because you'll have a better time on your new bike if you choose your own. See the pedal guide to find the best pedals for your riding style. We recommend clipless road pedals for control and efficiency.
