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.

DS450 Aluminum Frame
|
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.

DS
450's R-type Double A-arms |
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
selfcorrecting 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 –

the right leverage. Narrow body
and seat with smooth transitional
surfaces, wide foot pegs and deep
heel guards.
