First Look: 2008 Suzuki RM-Z250


2008 Suzuki RM-Z250

Features

New Engine
• KEIHIN FCR38MXS Carburetor with bat-wing type air guide plates deliver better mid-to-high power output while improving low throttle opening response.
• Exhaust port is narrowed 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.
• Modified piston profile for increased piston and cylinder efficiency.
• Hot starter relocated to the right hand side of the handlebar just like Ricky Carmichael’s 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.
• Showa rear shock absorber with a newly designed damper case and modified internal structure for a better controlled feel and increased bottoming resistance.
• Gold-colored chain and axle blocks give a full factory look.
• Race inspired wave-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.

Engine Features
• Compact 249cc, 4-stroke, liquid-cooled, DOHC, 4-valve engine - designed for maximum performance
• Advanced 4-valve cylinder head design with narrow included valve angle and titanium valves, plus new pentroof combustion chamber design for improved combustion efficiency
• SCEM composite-plated aluminum alloy cylinder for increased durability, optimum engine cooling and operating temperature
• Strong, reinforced airbox designed for durability and secure intake seal
• Automatic decompression system for easy kick starting • Semi-dry-sump lubrication system features separate oil chambers for the transmission and crankshaft using the transmission as the oil sump, allowing low crankshaft placement, reduced engine height and a 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

Chassis Features
• Twin spar aluminum alloy frame based on the championship winning RM-Z450 featuring a forged aluminum head-pipe and body frame
• Renthal tapered aluminum handlebars with Renthal-labeled handlebar pad for reduced vibration and improved rider feel
• On-the-fly clutch lever adjuster mounted to the clutch lever perch for rider convenience
