Colours

 

• Extreme Red (with White number plate and sidecovers)

 

Features and Benefits

 

Engine/Drivetrain

• Powerful 149cm3 liquid-cooled 4-stroke 4-valve Unicam engine produces impressive power across a wide rev range for easy-to-control operation.

 

• Compact, lightweight engine assembly weighs only 19.8 kilograms.

 

• Unicam valve train features a single camshaft directly actuating two 26mm steel intake valves combined with

twin, low-friction rocker arms actuating two 22.5mm steel exhaust valves. This compact design provides the light weight of a single-cam drive and an optimum combustion chamber shape for maximum power at all engine speeds.

 

• Crankshaft made of high-strength, low-carbon steel with carburized main journals for maximum durability at sustained high-rev operation.

 

• Forged slipper piston and rings are lighter than conventional designs, feature high 11.7:1 compression,

and rev quickly while maintaining excellent cylinder sealing and high-rpm power.

 

• Double-carburized connecting rod utilises big-end needle bearing for maximum high-rpm performance and durability.

 

• Lightweight NiCaSil cylinder lining ensures cooler operation for extended engine life.

 

• Press-fitted aluminium spark plug pipe fits between the two exhaust rocker arms, further contributing to compact cylinder-head design.

 

• Gear-driven balancer reduces vibration and drives the water pump.

 

• Lightweight, compact, internal auto decompression and handlebar-mounted hot-start system ensure easy starting, hot or cold.

 

• 32mm Keihin FCR flat-slide carburettor features four rollers on the slide for light throttle effort, smooth operation, crisp throttle response and excellent rideability.

 

• Carburettor features throttle position sensor (TPS) that helps maintain linear response throughout the rev range.

 

• Vertically split crankcase features a built-in oil pump, reducing weight compared to conventional designs.

 

• Twin-sump lubrication system separates the oil supply for the crankshaft, piston and valve train from the clutch and transmission. This ensures a cool supply of oil to the clutch, eliminates potential clutch and transmission material contamination of the engine oil, reduces the amount of circulating oil and permits the use of a smaller oil pump.

 

• Rugged six-plate clutch has ample surface area to handle the engine's impressive torque, while carefully matched clutch springs provide a light feel at the lever.

 

• Durable close-ratio five-speed transmission.

 

• Exhaust system uses lightweight stainless exhaust header and repackable aluminium muffler.

 

• Dual radiators feature a refined core area for improved heat dissipation compared to conventional dual-radiator designs.

 

Chassis/Suspension

• Lightweight, high-tensile steel frame with largediameter frame tubing and cross-member provides excellent turning performance and straight-line tracking.

 

• Removable sub-frame is strong and durable.

 

• Wide-section aluminium top and bottom tripleclamps position fork tubes far apart for excellent turning and control.

 

• Tapered-roller steering-head bearings enhance durability.

 

• 37mm inverted leading-axle Showa cartridge-type front fork features friction-reducing design to improve compression and rebound control.

 

• Front fork offers adjustable compression and rebound settings.

 

• Lightweight and rigid box-section aluminium swingarm.

 

• Pro-Link rear suspension system features fully adjustable Showa damper for superb compliance and wheel control.

 

• Unique CRF150R front and rear suspension settings deliver ideal bump absorption characteristics.

 

• Strong, lightweight wheels are durable and minimise unsprung weight.

 

• Lightweight front and rear disc brakes with highperformance pads offer powerful, precise braking control.

 

• Stout 15mm front and 17mm rear axles incorporate a surface treatment for added strength and durability.

 

Additional Features

• Lightweight plastic body components (radiator shrouds, sidecovers, rear fender, seat base, fuel tank, front fender and front number plate) feature a slim, aggressive style.

 

• Seat cushion foam follows the shape of the fuel tank, providing a smooth transition to increase rider mobility and comfort.

 

• Non-slip seat cover for increased rider control.

 

• Large-capacity airbox and reusable two-stage foam air filter.

 

• High-quality Dunlop tyres.

 

• Handlebar bend optimises rider position and comfort.

 

• Adjustable front brake lever and compact mastercylinder assembly.

 

• HRC works-type rear brake system integrates the rear master cylinder and fluid reservoir, eliminating the separate rear master-cylinder reservoir and hose.

 

• Works-type handlebar grips add to rider comfort.

 

• Stainless steel clutch cable for long life and improved feel and action.
