2008 Can-Am DS 450 EFI


Introducing the 2008 Can-Am DS™ 450 EFI ATV. Its radical power comes from a Rotax® engine. Its ultra light weight comes from cutting-edge computer design and fresh ideas. Its features come from the input of MX racers.

It is the new benchmark for performance, handling and control – on track and off – thanks to the most power in the class, lowest weight, most centralized mass, lowest unsprung weight, and fully-adjustable sport-tuned suspension.**

DS 450 EFI Highlights

  • Responsive and easy to maneuver, thanks to centralized masses and unmatched power-to-weight ratio
  • At 345 pounds (156 kg) dry, it is the lightest 450 sport ATV
  • New Rotax 450 engine is the most powerful in the class
  • Lightweight ALTEC™ aluminum chassis with dual-pyramidal frame – 13% lighter than the best-in-class competitor
  • Innovative R-Type™ front and rear suspensions deliver handling, control, and feel
  • KYB‡ HPG aluminum body piggyback shocks with full adjustability
  • Wilwood disc brakes: 182mm wave-type discs with inverted twin-piston calipers, 198mm wave-type disc in rear
  • Performance features like racing kick-up footpegs, detachable headlights, interchangeable fenders

DS 450 EFI Key Features

Rotax® 4-TEC 450 EFI – This new engine is the most powerful in the class. The top-end of the DOHC single has DNA from the Rotax V990 which powers the Aprilia‡ RSV 1000 R sportbike while the crankcase, clutch and transmission are specifically designed for the rigors of offroad riding. Its free-flow design – with the largest piston bore, intake valves and throttle body of the segment – delivers awesome power and great potential for performance tuning. A sophisticated EFI system with superfast micro-controller optimizes performance at every rpm, compensating for both temperature and altitude; throttle response is instant.

ALTEC™ aluminum frame – Aerospace-grade aluminum in dualpyramidal design is exceptionally strong and lightweight. Unique aluminum lock-bolt fastening system eliminates the need for welds. 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.

R-type double A-arm front suspension – The new R-Type forged aluminum double A-arm front suspension delivers razor-sharp handling, remarkable bump absorption, and confident tracking. The radical design with inverted dual-piston caliper – on the inside of the disc – enables placement of the ball-joints and kingpin axis deep inside the wheel for reduced scrub and steering kickback, as well as self-correcting behavior under hard braking. All this in a lightweight package with less unsprung weight than competitive designs for a better ride and improved control.

KYB HPG piggyback shocks – Aluminum-bodied shocks with compression and rebound adjustment and threaded pre-load adjustment. Features 9.5-inches (24 cm) of travel in front, 10.2 inches (26 cm) in rear. Lightweight, capable and adjustable.

R-Type rear swing arm suspension – Lightweight design dramatically reduces unsprung weight for quick response, exceptional traction capability and less rider fatigue. Cast-aluminum swingarm with rising-rate linkage, hollow Chromoly 4140 rear axle, extended-reach aluminum hubs and aluminum chain sprocket.

Wilwood™ braking systems. Inverted dual-piston calipers – mounted inside front rotors – enable unique knuckle/spindle/A-arm design. Front and rear rotors’ wave shape is computer designed for exceptional cooling.

Performance wheels/tires – Specifically-designed ITP‡ Holeshot‡ SR tires to get maximum performance from the DS 450 EFI. The rims are lightweight, yet durable, because of aluminum construction with rolled bead.

Performance ergonomics – Designed to give the active sport rider room and the right leverage. Narrow body and seat with smooth transitional surfaces, wide foot pegs and deep heel guards.

Performance features – Detachable headlights, interchangeable front fenders
