Introduction

Introduction 2013 RM-Z450/250 ENGINEERING TARGET 1.Meeting new FIM sound control without sacrificing engine performance. 2.Enhance mid range power to be practical in racing battle. 3.More controllable handling character to be accepted by wider range of riders.

Introduction 2013 RM-Z450 from outside • As the above mentioned concept, styling design is unchanged. • From outside, it might look same with 2012 model except graphics and plastic parts color. 2012 RM-Z450 2013 RM-Z450

Introduction But under its skin…….

Engines Piston Piston of RM-Z250 also received feedback of FEM analysis. New piston is 3% lig lighter without sacrificing the rigidity. （ 250 ） Back side of piston is

Engines Piston / Piston pin / Connecting rod （ 450 /250 ） DLC coated piston pin (450 only) Lighter 13% lighter Thicker and shorter connecting rod (450 only) Piston (450 only) piston pin (250 only) Increased rigidity Faster throttle response Enhanced mid-range power delivery Better combustion * RM-Z250 piston is 3 % lighter. Piston pin is efficiency changed but no DLC coat. Connecting rod of 250 is unchanged.

Engines Current model Crank pin （ 250 only ） New model Change the shape of passage in crank pin. Capture more sludge, better lubrication Enhance the durability of the bearing at the big end.

Engines Cam chain guide (450 only) Changed cross section surface Changed material (From T to H) Enhanced abrasion resistance Enhanced rigidity and strength Better reliability

Engines Air cleaner (450 / 250) 250 450 Change the shape of air cleaner outlet Increase the volume of the air Increase the volume of the air cleaner cleaner outlet tube (160ml) outlet tube (60ml) Increase bottom-to-mid Enhance the throttle range power delivery response

Engines Back panel of cleaner box (450 only) Now made of carbon fiber mixed material Reduce intake noise

Engines Muffler / Exhaust pipe Meeting new （ 450 / 250 ） FIM sound control Redesigned Muffler structure Enhanced low-to-mid Extended Exhaust pipe range power delivery 450→50mm (European spec only) 250→40mm Easy maintenance of Conventional bolts to fix end cap glass wool * Muffler internal changes only applied to European spec.

Engines Camshafts *250’s camshafts (450 / 250) 450 250 Changed Intake cam timing Changed cam profile Increased intake cam’s working angle Changed intake cam’s working and lift amount angle and lift amount Delayed Exhaust cam timing Increased controllability Smooth characteristic Enhanced low-to-top range Increased controllability power delivery

Engines Transmission / Shift cam (450 / 250) All new Transmission (250) *250s transmission Redesigned Shift cam Redesigned stopper spring More precise Redesigned shift cam stopper plate gear shift Redesigned drive shaft operation New Clutch release (250 only) Changing the sprocket spacer’s ring Redesigned Transmission (change the Better Shift feel shape of 2nd, 3rd, 4th and 5th gears) (450)

Engines Radiator (250 only) 2012 model 2013 model Better cooling efficiency = New by-pass hose connects L & R More stable performance Revised Hose routing Easier for maintenance (Easier to add coolant) Changed fin pitch

Engines RM-Z450 RM-Z450 (European spec) More power and torque from bottom end to mid range!!

Engines RM-Z250 RM-Z250 (European spec) More power and torque from mid to high rpm range!!

Chassis

Chassis Rear suspension Air cleaner outlet tube Frame Air cleaner box Seat rail Under bracket Front forks Muffler exhaust pipe Linkage bolt Linkage rod 2013 RM-Z450 Chassis changes

Chassis Frame / Seat rail Reduced the weight by 1% (91g) (450 / 250) (450 only) Change the structure of frame head, tank rail, down tube and bridge tube Changed the material of engine mounting bracket from aluminum alloy to steel (250 only) Changed the shape and position of engine mounting bracket (450 only) Optimized rigidity balance More controllable handling character

Chassis Front forks (450 / 250) Separating the spring and damping tasks Reduced friction Increased absorption performance Reduced weight by 2%

Chassis Front forks (450 / 250) Inner tube diameter is increased Spring pre-load is now adjustable from 47 mm to 48mm Optimized stability and Allowing wider range of absorption setting
