The Scandinavian cross-country rocket: Even more sporty and tauter than the FE models and therefore born for fast enduro trails, hard cross-country races and narrow motocross tracks. The equipment is of the finest quality and lights are nowhere to be found on the uncompromisingly lightweight FX 450.
Engine and transmission perfectly tuned for cross-country and motocross use.
Well thought-out ergonomics and sports-oriented, taut high-end suspension enable playful handling on absolutely every track.
High-end Renthal handlebars, extremely stiff tapering, extremely light, perfect shape for an active riding position, MX handguards included.
CNC-machined triple clamps with 22 mm offset, optimally matching the bending behaviour of the forks, special clamping, maximum strength, minimum weight.
For greater stiffness, the engineers have significantly reinforced the area of the frame around the steering head on the 4-stroke models, reduced frame flex at the decisive points, substantially improved stability of the bike at high speeds, absolutely precise control of the front wheel.
6-speed transmission, primary gear ratio with narrower spread, adapted for use on cross-country and motocross tracks.
Super-light 19“ rear wheel with motocross tyre, large selection of 19“ MX tyres.
48 mm WP USD forks, state-of-the-art damping thanks to closed cartridge technology, highest bottoming resistance, supremely sensitive, extremely effective.
