Can Am DS 450

Can Am DS 450

ALTEC™ Aluminum Chassis:

 

The Can Am DS450 frame is very unique. The frame is made from aerospace-grade aluminum and configured in a dual-pyramidal design. Strength comes from computer-optimized design rather than heavier or added materials. The pyramidal structure has been proven on BRP’s Ski-Doo® REV™ and REV-XP™ snowmobiles. Can-Am uses locking bolts instead of traditional welds to hold the frame members together. The frame is13% lighter than the best-in-class competitor.

Engine:

Rotax 449cc derived from BRP Can-Am's Aprillia 1000R road bike. This is completely new Rotax® 4-TEC® 450cc engine. It's a 449cc Electronic Fuel Injected engine that Can-Am says is by far the most powerful in its class. 9% more HP than the best-in-class competitor.

Suspension:

All-aluminum A-arms, Knuckles And Wheel Hubs
Unsprung weight is the weight of all the components that follow the wheel travel, or everything not supported by the springs. The lower the unsprung weight, the faster the wheel assembly can move up and down to follow terrain irregularities and absorb impacts without transmitting too much movement to the vehicle. This results in a smoother ride and keeps the tires in contact with the ground. When unsprung weight is lower, the springs and shocks can be tuned to handle motion induced by the terrain, instead of trying to control inertia of the ATV’s suspension.

Inverted Brake Calipers And Peripheral Brake Discs
By putting the caliper "inside" a peripheral brake disc, the diameter can be increased as close as possible to the inside of the wheel. Larger discs improve potential braking power and precision feel.

Short Spindle Length
The spindle acts as a lever on the steering ball joints. The longer the lever, the more kickback is transmitted to the steering when the wheel hits an obstacle. With a long spindle lever, small impacts are felt as annoying kickback, tracking in brake bumps requires steering corrections, and bigger impacts take a toll on a rider's wrists. The DS 450’s short spindle lever reduces the negative steering feedback, providing a more confidence- inspiring ride.

Longest A-arms Possible For A Given ATV Width
When a double A-arm suspension travels up and down, the wheel moves in and out, in a "butterfly" motion. A short A-arm results in a pronounced arc and produces a significant amount of scrub. This sideways movement of the wheel causes loss of tire lateral traction and makes the vehicle dart from side to side in whoops sections. The DS 450 has longer A-arms so the radius of the arc produced by the A-arms is larger, resulting in less scrub – or outward movement of the wheel. The result: more predictable and precise handling.

Negative Scrub Radius
When braking, there is often a difference in grip between the two front wheels. This difference sends the ATV pivoting around the wheel that has more grip. This effect is amplified by a positive scrub radius, because that wheel is also being steered outward by forces acting on the tire – the positive scrub radius acts as the lever turning the wheels out around the kingpin axis. However, a negative scrub radius will cause the wheel to turn in under braking loads. So the turn-in effect fights against the pivoting motion of the bike around the front wheel that has more grip. The result: self- correcting behavior, providing the confidence to enter corners faster, and brake harder and later.
