  • The Top Fuel 5 is a full-suspension mountain bike that’s equal parts efficient and capable. It soaks up rough, rugged descents but still flies like a rocket up hills and on flat stretches. The light and sturdy alloy frame is built with parts picked for performance and value, making this bike perfect for your first full-suspension trail bike.


    1. This bike’s killer suspension set-up is both efficient and ready to party
    2. Mino Link lets you make small adjustments to your geometry quickly and easily, even mid-ride
    3. A sleek internal storage compartment gives you a versatile spot to stow tools and gear
    4. New, removable Knock Block has a bigger steering angle to keep cables and hoses safe without sacrificing turning radius
