DS 450

Aluminum sprocket and sprocket hub

Lightweight, durable sprocket and sprocket hub reduces weight.

Racing kick-up foot pegs with heel guards

Wide foot pegs with kick ups and integrated heel guards offer riders superb footing and protection.

349-lb dry weight

Lightweight design contributes to the DS 450 ATV’s nimble and efficient handling.

Interchangeable fenders

An added performance and convenience feature to simplify maintenance, cleaning and fender replacement.

R-Type cast aluminum swingarm rear suspension

Features Chromoly hollow rear axle, extended-reach aluminum wheel hubs, aluminum sprocket, cast-aluminum swingarm, 10.5 in. (267 mm) of travel. For the lowest possible unsprung weight and the most mass centralization.

KYB HPG aluminum piggyback rear shock

Kayaba HPG piggyback shock with compression, rebound & threaded preload adjustments and 10.5-in. (267 mm) of travel. Giving the riders the flexibility of tuning the suspension to fit the terrain and riding style.

520 O-ring chain

Heavy-duty, race-ready O-ring chain can handle high stress of racing.

Polished aluminum Wheels

Race-inspired radiator grill

Hollow rear axle

The hollow, high-strenght steel axle has been shortened by extending the lenght of aluminum hubs. The final design: a shorter axle mated with "spyder" all-aluminum 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.

5-speed manual transmission

Competition-ready 5-speed manual transmission with foot-shifter and manual clutch lever. Features heavy-duty clutch and 9 friction plates with DirectLink mechanism.

Class-leading power-to-weight ratio of any 450-class sport ATV*

The DS 450 features an innovative, no-weld ALTEC™ aluminum 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, aluminum parts) and mass centralization engineering to reduce unsprung weight and the DS 450 is unmatched in its class.

KYB HPG aluminum piggyback front shocks

Kayaba HPG piggyback shock with compression, rebound & threaded preload adjustments and 9.5-in. (241 mm) of travel. Giving riders the flexibility of tuning the suspension to fit the terrain and riding style.

Lock-bolts

Only ATV in the industry to feature Lock-Bolt fastening system (a technology used in the aviation industry) instead of welds or gussets. Resistant to vibration, high-tensile aluminum Lock-Bolts are pre-stretched and then a collar is pressed in the deep grooves of the stud’s shank.

EFI with 46-mm throttle body, 16-bit CPU with 32-MHz clock speed

Electric start

Push-button electric start for easy start

Low-profile seat

45.3-hp Rotax 4-TEC 449cc, liquid-cooled, single-cylinder 4-stroke engine

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.

Shortened spindle

The spindle acts as a lever on the steering ball joints. The longer the lever, the more the kickback is transmitted to the steering when the wheel hits an obstacle. The DS 450 short spindle lever reduces negative steering feedback, providing a more confidence-inspiring ride.

ITP Holeshot SR front and rear tires

Detachable headlights

Remove the headlights for racing.

33-in. seat height

Low seat height provides a lower center of gravity and race-ready positioning for aggressive riding.

Inverted brake calipers

Inverted twin-piston front brake calipers offer impressive stopping power because of the larger brake discs (182 mm). By putting the caliper "inside" a peripheral brake disc, the diameter can be increased as close as possible to the inside of the wheel. This set-up allows for larger brake discs and improved stopping power and feel. Plus, the peripheral disc brake leaves room inside to push the lower A-arm ball-joint deep inside the wheel.

WIllwood hydraulic disc brakes

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.

No weld, ALTEC twin pyramidal aluminum frame

A maximum strength, no-weld, all-aluminum frame that uses a twin pyramidal structure. Major components are firmly secured with aluminum fasteners called lock-bolts. The frame is stronger yet much lighter than a traditional ladder frame.
