The front end of the DS 450 X mx is completely adjustable with a shim-style adjustment. Each shim represents one-degree of adjustment with camber adjustable from 11 degrees to 15 degrees; caster is adjustable from 3 degrees to 10 degrees. This allow the racer to completely "dial in" the DS 450 X mx for his or her preference.
Competition-ready 5-speed manual transmission with foot-shifter and manual clutch lever. Features heavy-duty clutch and 9 friction plates with DirectLink mechanism.
Kashima-coated KYB HPG C46 alumunium remote reservoir rear shock with dual-speed compression, rebound and preload adjustments, and 10.7 in.(272 mm) of travel
Graphics and seat cover exclusive to the X package.
The DS 450 features an innovative, no-weld ALTEC™ alumunium frame and a hearty Rotax® engine for the industry’s best power-to-weight ratio of any 450-class sport ATV. Combined those features with other weight-saving innovations (hollow rear axle, alumunium parts) and mass centralization engineering to reduce unsprung weight and the DS 450 is unmatched in its class.
High-performance ITP QuadCross MX Pro tyres give maximized traction on track surfaces, especially for blue-grooved. The rear tyres are 18-inch motocross-ready tyres complete with 8-inch (203 mm) black, alumunium ITP T-9 beadlock wheels with an inner reinforcement ring.
Features Chromoly hollow rear axle, extended-reach alumunium wheel hubs, alumunium sprocket, cast-alumunium swingarm. For the lowest possible unsprung weight and the most mass centralization.
The DS 450 is equipped with a 449 cc 4-stroke EFI Rotax engine, offers the largest bore (97 mm) and the largest intake valves (38 mm) from the DOHC 4-valve head with 97 x 60.8 mm bore and stroke. The EFI uses the largest throttle body (46 mm), 16-bit CPU with 32-MHz clock speed and an almost straight intake path. With a concept referred to as ''Durchzugskraft'' or flow dynamics optimization, the engine breathes easily and can produce more power. The DS 450 delivers the best power-to-weight ratio.
Wide foot pegs with kick ups and integrated heel guards offer riders superb footing and protection.
High-performance ITP QuadCross MX Pro tyres give maximized traction on track surfaces, especially for blue-grooved. Up front, 20-inch (508 mm) ITP QuadCross MX Pro tyres mounted on 10-inch (254 mm) black, alumunium ITP T-9 wheels.
Kashima-coated KYB HPG C40 alumunium piggyback front shocks with dual-speed compression, rebound and preload adjustments and 10.7 in. (272 mm) of travel
Low seat height provides a lower centre of gravity and race-ready positioning for aggressive riding.
A +1-inch (25 mm) extra-strength steering stem with anti-vibe mounts comes standard on the DS 450 X xc and the DS 450 X mx. This gives the racer a better feel for the ATV while in an attacking stance out on the course. There is no need to buy an aftermarket stem to be competitive. Mounted to the steering stem is an alumunium 6061-T6 taper-profile handlebar with square racing pad.
A maximum strength, no-weld, all-alumunium frame that uses a twin pyramidal structure. Major components are firmly secured with alumunium fasteners called lock-bolts. The frame is stronger yet much lighter than a traditional ladder frame.
The hollow, high-strenght steel axle has been shortened by extending the lenght of alumunium hubs. The final design: a shorter axle mated with "spyder" all-alumunium hubs with precision machined splines and longer arms. The rear unsprung weight of the DS 450 is therefore reduced, which also has a significant impact on mass centralization and dry weight.
Straight from the factory, the DS 450 X mx comes complete with lightweight alumunium nerf bars with netted heel guards. If one desires, the nerf bars, side extensions and heel guards can be removed with ease.

At 50-in. (1,270 mm) wide, the DS 450 X mx meets the recognized standard for motocross racing with its stock A-arms. Racers will not have to purchase expensive aftermarket A-arms to take the X mx to the track and be competitive.
Mounted inside front rotors, the DS 450’s exclusive inverted dual-piston calipers allow for a unique knuckle / spindle / A-arm design. Computer-designed, wave-type front-and-rear rotors offer exceptional cooling and enhance all-around handling.
The DS 450 X mx is a motocross-inspired sport ATV with a design geared towards performance. It comes standard with KYB HPG front and rear shocks, aluminium nerf bars and ITP QuadCross MX PRO tyres on black aluminium ITP T-9 wheels. It also features an all-aluminium frame, hollow rear axle and inverted brake callipers. We think that it’s performance at its best. It's a pure racing machine in mind and the repeated success in pro series has proven us right!
