2008 CAN-AM DS450 EFI

2008 Can-Am DS450 EFI – Lightweight Precision Meets Sport-Quad Power

Under the aggressive bodywork is a 449 cc Rotax 4-TEC liquid-cooled single-cylinder engine, featuring DOHC and four valves. Sporting the largest bore, intake valves, and throttle body in its class (a 46 mm unit), it delivers class-leading horsepower and unmatched throttle responsiveness—courtesy of its advanced EFI system with rapid micro-controller tuning for altitude and temperature changes  . Power is transmitted through a sturdy 5-speed manual gearbox with a wet, multi-plate clutch and a durable 520 O-ring chain drive  .

Suspension & Handling

Ride control is where the DS450 excels. The R-Type forged aluminum double A-arm front suspension and cast-aluminum swingarm rear are paired with adjustable KYB HPG piggyback shocks—tuned for adjustable compression, rebound, and preload. Front travel measures about 9.5 in, while the rear stretches to approximately 10.5 in—perfect for absorbing tough terrain with finesse  .

Brakes & Wheels

With dual 182 mm wave-style discs and inverted twin-piston Wilwood calipers in front, and a 198 mm wave rotor with single-piston caliper in the rear, the DS450 EFI guarantees powerful, fade-resistant braking. Mounted on lightweight polished aluminum wheels with ITP Holeshot SR tires (21×7-10 front, 20×10-9 rear), the setup is both rugged and nimble  .

Ergonomics & Design

Can-Am optimized mass centralization—every component is positioned to keep the center of gravity low and centered. A narrow seat, wide footpegs with heel guards, and racing-inspired kick-up footrests offer agile handling and comfort. Additional touches include detachable headlights and interchangeable fenders for customization and ease of servicing   .

What Riders Say

Some riders praise its looks and rare performance edge:

“They are a really pretty quad. Performance is awesome. Worth the buy.”

However, many also warn about maintenance complexity and parts availability, noting that the DS450 can be more intricate and finicky than other more mainstream 450 class ATVs
