2009 Suzuki RM-Z250
2008 RM-Z250 The RM-Z250
features a compact, lightweight and powerful 250cc 4-stroke
engine design, a strong and lightweight aluminum chassis,
Showa suspension components and many high-performance features
for the ultimate 250cc 4-stroke racing machine. The RM-Z250
engine is based around an over-square bore x stroke design,
with liquid-cooling, titanium valves and double overhead
billet cams. The engine is housed by a lightweight, twin-spar
aluminum-alloy frame combining aluminum forgings, extrusions
and stampings welded into a single unit. The whole package is
supported by a Showa inverted, twin-chamber, cartridge fork
and Showa remote reservoir rear shock. The RM-Z250 features a
unique aluminum rear swingarm built using hydro-formed,
thick-wall tapered arms welded to a cast linkage bracket and
forged axle holders. Other features include Dunlop tires
mounted on lightweight aluminum rims with a special
spoke/nipple design, plus Renthal aluminum handlebars as
standard equipment. Included with this year's new model are
all the benefits of Suzuki's race contingency, trackside
support, Tony D School and Good scholar program. All these
added benefits are exclusive to Suzuki riders.
The RM-Z250 for 2008: it's taking the four-stroke world by
storm!
New Features
-
Race inspired
brake
rotors provide better cooling performance and increased mud
deflection in muddy conditions.
-
Newly designed pegs include increased clearance between the
mounting bracket and footrest to prevent mud from caking up.
-
Gripper seat has been improved this year by adding projected
cross-shaped patterns on the top surface to provide additional
grip.
New Engine
-
KEIHIN FCR 37 MX Carburetor with bat-wing type air guide
plates result in better mid-to-high power output while
improving low throttle opening response.
-
Exhaust
port is narrowed down on the left side for an increase of
mid-to-high power output.
-
Muffler construction revised improving power output
throughout the rev range.
-
Clutch judder springs added for a more controllable
operation feel.

Hot starter relocated to the right hand side of the
handlebar just like Ricky Carmichaels Championship winning
RM-Z450.
New Chassis
-
Brackets are added to the side frame pipes and tank rails
for increased balance rigidity.
-
Lower bridge pipes reduced in size resulting in improved
shock-absorption feel while maintaining ample strength.
-
Showa cartridge-style front fork with 47mm inner tube, plus
22 -way compression damping and 11.8 inches of wheel travel.
Sections within the fork were modified to reduce weight and
improve shock absorption.

low center of gravity
-
AC-CDI ignition system with two ignition maps automatically
increases engine idle speed to reduce engine brake effect -
ignition timing and rev limiter set for optimum high rpm and
over-rev performance
