Can Am DS 450
Can Am DS 450 Features
Rotax 449 cc EFI enginge
The Can Am DS 450 is equipped with a 449 cc 4-stroke EFI Rotax enginge, offers the largest bore (97 mm), the largest intake valves (38 mm), the largest throttle body (46 mm), and an almost straight intake path. With a concept referred to as "Durchzugskraft" or flow dynamics optimizaion, the enginge breathes easily can can produce more power. The DS 450 delivers the best power-to-weight ratio.
A maximum strength, no-weld, all-aluminum frame that uses a twin pyramidal structure. Major components are firmly secured to the Can Am DS 450 with aluminum fasteners called lock-bolts. The frame is stronger yet much lighter than a traditional frame.
This high-tensile, aluminum fastener eliminates the need for welds and heavy gussets. Airbus uses the same technology to attach the 119-foot wings of the A380, the world's largest aircraft. The stud is pre-stretched. The collar is then pressed in place over the deep grooves of th sud shank. Since there are no threads, the assembly is resistant to vibration.
Hollow Rear Axle
The hollow, high-strength steel axle on the Can Am DS 450 has been shortened by extending the length of aluminum hubs. The finl design: a shorer axle mated with "spider" all aluminum hubs with precision machined splines and longer arms. The rear unsprung weight of the Can Am DS 450 is therefore reduced, which also has a significant impact on mass centraliation and dry weight.
R-Type Double A-Arm Front Suspension
Longest aluminum upper and lower A-arms for a 46-inch sport ATV, one-piece aluminum knuckle and short spindle.
Inverted Brake Calipers
The Can Am DS 450 has inverted twin-piston brake calipers to offer impressive stopping power because of the larger brake discs.
Maximum Mass Centralization
Mass moment of inertia is a measure that indicates how difficult it is to put an object into rotation around its axis. The lower the measurement, the higher the mass centralization. The mass moment of inertia for the Can Am DS 450 is as low as possible for the greatest possible agility.
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 Can Am DS 450 short spindle lever reduces negative steerig feedback, providing a more conidence-inspiring ride.
R-Type Rear Suspension
The Can Am DS 450 features chromoly hollow rear axie, extended-reach aluminum wheel hubs, aluminum sprocket, cast-aluminum swingarm, 10.5 inches of travel, kayaba HPG piggyback shock with preload, compression and rebound adjustment for the lowest possible unsprung weight and the most mass centralization.
KYB HPG Piggyback Front Shocks and Rear Shocks
Kayaba HPG piggyback shocks with compression, rebound and preload adjustments giving riders of the Can Am DS 450 flexibility of tuning the suspension to fit the terrain and riding style.
