DS 450 EFI Key FeaturesRotax® 4-TEC 450 EFI = This engine features top-end 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 off-road 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 dual-pyramidal 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.
Redesigned radiator grill = Can-Am redesigned the radiator grill of the 2010 DS 450 family for
added protection and cooling performance on both the trail and race course.
R-type double A-arm front suspension = The 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 risingrate
linkage, hollow Chromoly 4140 rear axle, extended-reach aluminum hubs and aluminum chain sprocket.
Wilw ood™ 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.
DS 450 X mx EFI Key FeaturesGraphics package = The 2010 DS 450 X mx comes with an updated yellow and black graphics
package. The package adds more yellow accents to the classic X Package black scheme.
50-inch width = At 50 inches (1270 mm) wide, the DS 450 X mx meets the recognized standard for motocross
racing with its stock +2 (51 mm) A-arms. Racers will not have to purchase expensive aftermarket A-arms
to take the X mx to the track and be competitive.
Anti-vibe steering stem = A rubber-mounted +1 (25 mm) anti-vibe steering stem comes standard
on the DS 450 X mx. This gives the racer a better feel for the ATV while out on the track in a racing
stance. Again, there is no need to buy an aftermarket stem to be competitive. Mounted to the steering
stem is an aluminum 6061-T6 taper-profile handlebar with square racing pad.
Camber- and caster-adjustable front end = The front end of the DS 450 X mx is completely
adjustable with a shim-style adjustment. Each shim represents one-degree of adjustment with camber
adjustable from 11 degrees to 15 degrees; caster is adjustable from 3 degrees to 10 degrees. This allows
the racer to completely “dial in” the DS 450 X mx for his or her preference.
Race-bred suspension = The suspension, both front and rear, features (piggyback up front and
remote reservoir for the rear) KYB HPG shocks with Kashima coating. This high-performance shock
coating reduces internal friction and heat for consistent shock performance (less stiction and less fade).
The shocks are fully adjustable with high- and low-speed rebound and compression damping, as well as
preload adjustment. Two separate-rate springs with a crossover up front allow for maximum performance
in all conditions. Front and rear travel is 10.7 inches (272 mm).
ITP QuadCross MX Pro tires and ITP T-9 wheels // High-performance ITP Quadcross MX Pro tires
give the DS 450 X mx maximized traction on a variety of track surfaces, but especially for blue-grooved
tracks. The rear tires are 18-inch motocross-ready tires complete with 8-inch (203 mm) black, aluminum
ITP T-9 beadlock wheels with an inner reinforcement ring. Up front, 20-inch (508 mm) ITP Quadcross MX
Pro tires mounted on 10-inch (254 mm) black, aluminum ITP T-9 wheels give the DS 450 X mx precise
cornering ability with decreased lateral roll.
Aluminum nerf bars = In order to race motocross at any level, nerf bars are a requirement.
Straight from the factory, the DS 450 X mx comes complete with lightweight aluminum nerf bars with
netted heel guards. Side extensions are adjustable to a variety of customizable widths. If one desires, the
nerf bars and netted heel guards can be removed with ease.
Adjustable-width axle = Many of today’s top motocross pros are choosing to race with a rear width
that is slightly narrower than the front-end width. This is possible with the DS 450 X mx thanks to a
chromoly 4140 adjustable-width hollow axle. Adjustment from 46 (1168 mm) to 50 inches (1270 mm) is
possible with .5-inch (13 mm) spacers.
Motocross-specific ride height = The DS 450 X mx comes from the factory with a ride height of
seven inches (178 mm) (assuming a 175-pound rider (79 kg) with gear), meaning exceptional cornering
performance for a lower centre of gravity.
DS 450 X xc EFI Key FeaturesGraphics package = The 2010 DS 450 X xc comes with an updated yellow and black graphics
package. The package adds more yellow accents to the classic X Package black scheme.
46-inch width = At 46 inches (1168 mm) wide, the DS 450 X xc is the perfect width for the tight woods
courses cross-country racers love. With forged aluminum upper and lower A-arms, the X xc can precisely pick
its way through the trees.
Anti-vibe steering stem = A rubber-mounted +1 (25 mm) anti-vibe steering stem comes standard on
the DS 450 X xc. This gives the racer a better feel for the ATV while in an attacking stance out on the course.
There is no need to buy an aftermarket stem to be competitive. Mounted to the steering stem is an aluminum
6061-T6 taper-profile handlebar with square racing pad.
Caster-adjustable front end = The dual aluminum A-arm front end of the DS 450 X xc comes with a
shim-style caster adjustment. Each shim represents one-degree of adjustment with 3 degrees to 10 degrees of
caster adjustment. This allows the racer to completely “dial in” the DS 450 X xc for his or her preference.
Race-bred suspension = The suspension, both front and rear, features (piggyback up front and
remote reservoir for the rear) KYB HPG shocks. The shocks are fully adjustable with high- and low-speed
rebound and compression damping, as well as preload adjustment. Two separate-rate springs with a
crossover up front allow for maximum performance in all conditions. Front travel is 9.6 inches (244 mm)
while rear travel is 10.5 inches.(267 mm).
ITP Holeshot GNCC tires and ITP T-9 wheels = The DS 450 X xc features 20-inch (508 mm) rear
ITP Holeshot GNCC tires mounted on 10-inch (254 mm) black, aluminum ITP T-9 beadlock wheels. Up front,
21-inch (533 mm) ITP Holeshot GNCC tires mounted on 9-inch (229 mm) black, aluminum ITP T-9 wheels with
beadlock rings. The taller lugs of the Holeshot GNCC provide superior traction in demanding race conditions.

aluminum nerf bars with aluminum heel guards. Side extensions are adjustable to a variety of customizable
widths. If one desires, the nerf bars and heel guards can be removed with ease.
Adjustable-width axle = The DS 450 X xc features a chromoly 4140 adjustable-width hollow axle.
Adjustment from 46 inches (1168 mm) to 50 inches (1270 mm) is possible with .5-inch (13 mm) spacers
for rider preference.
Cross-country -specific amenities = Aluminum skid plates for the frame and swingarm are standard
on the DS 450 X xc for added protection on demanding courses. From the factory, the ride height of the X xc is
set at 7.5 inches (101 mm)(assuming a 175-pound (79 kg) rider with gear), meaning exceptional cornering
performance for a lower centre of gravity. Wind deflectors that feature a full-wrap aluminum brace are mounted
to the handlebars.
