Amplify your trail-game with the all-new Fourstroke AMP LT built to perform on every terrain.
This advanced XC performance machine delivers a progressive riding feel with 120 mm of revolutionized APS dual-link suspension travel. Hidden trail-racing power comes curtesy of the trailblazing TQ-HPR50 drive system for nonstop uphill and downhill speed to make sure nothing stands in your way. The full-carbon frame includes our most progressive Big Wheel Concept Race geometry to accommodate two water bottles, an integrated fork stopper and frame protection. Fourstroke AMP LT TWO has you hit those trails at speed with a Shimano XT 12 spd drivetrain, RockShox SID SL Select+ fork and RockShox SIDLuxe Select+ shock, a DT Swiss M 1900 wheelset with 30mm inner width, X-Fusion Manic seatpost and the powerful TQ-HPR50 drive unit.
Hidden Power
Fourstroke AMP LT levels up with hidden power thanks to the TQ-HPR50 drive unit. Powerful, light and compact, it is seamlessly integrated into the frame for an uncompromised look and natural ride feeling. Arriving with the harmonic pin-ring transmission, 360 WH battery, 2” fully integrated display and minimalistic handlebar remote, this brand-new system makes sure to amplify your trail game.
Optimized APS Suspension
More traction equals more speed and that is what we’re after. Next-level kinematics tuning, and best-in-class suspension performance delivers full traction, great efficiency, and active suspension on every terrain. Resulting in faster times, this new and improved full-feature suspension allows you to pedal efficiently, brake hard, and charge rough terrain without compromise.
Redefined Geometry
BWC Race is tailored to a fast and progressive racing style designed to attack the steepest and loosest courses with the improved 66.5˚ head angle and a long front-end. The 429 mm short chainstays deliver power with proven traction on the most technical sections. The lowered bottom bracket and a steep 77˚ seat angle provide perfect weight distribution and handling.
Go Long
The Fourstroke AMP LT is versatile by design to let you carry speed with confidence on technical trails. It has been optimized to fit two water bottles or a TQ range extender plus a bottle; it comes with 120 mm of suspension travel to push the trail boundaries with 34 to 35 mm forks and a 60 mm tire clearance to fit 2.4” Maxxis Rekon tires with EXO protection.
Design Boost
Put the hammer down! The redesigned chassis excels in torsional and pedalling stiffness for unparalleled power delivery. A true performance leap that boosts one of the most successful Cross-Country bikes on the scene to a new level.
Dropper Post
Fourstroke AMP LT features a standard seat tube that allows the use of classic 31.6mm dropper posts for extended versatility and optimization.
