Engine/Drivetrain

• High-Performance Unicam® cylinder head design
• Compact, lightweight engine designed specifically for ATV usage is worthy of its CRF®    heritage.
• Features an electric starter that drives the clutch side of the crankshaft to provide superior lubrication of starter gears and to produce a narrow engine with a short, strong crankshaft.
• Lightweight, compact, internal auto decompressor provides superb cold-starting and hot-starting operation.
• Crankshaft is made of high-strength, low-carbon steel with carburised main journals for maximum durability at sustained high-rpm operation.
• Cylinder-head cover is made of magnesium to reduce engine weight.
• Forged three-ring 12.0:1 compression slipper piston is lighter than a conventional design, revving quickly while maintaining excellent cylinder sealing and high-rpm power.
• Maximum engine rpm is 9850.
• Double-carburised connecting rod utilises a big-end needle bearing for maximum high-rpm performance and durability.
• Nikasil cylinder lining is lightweight and provides cooler and quieter operation for extended engine life.
• Press-fitted steel spark plug pipe fits between forked exhaust rocker arms, further contributing to compact cylinder-head design.
• 40mm Keihin FCR-type carburettor features four rollers on the flat slide, resulting in very light throttle effort, smooth operation, crisp throttle response and excellent rideability.
• Carburettor features a Throttle Position Sensor (TPS) that helps maintain linear response throughout the rpm range.
• 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 clutch and transmission material contamination to the engine oil and reduces the amount of circulating oil and the required size of the oil pump.
• Vertically split crankcases feature a built-in oil pump, reducing weight compared to a conventional design.
• Left-side countershaft bearing and axle carrier feature double-row bearings for added durability.
• Exhaust system uses a lightweight, stainless steel header and muffler.
• Exhaust system and free-flowing muffler increase performance while maintaining low noise levels.
• Light-weight radiator with fin pitch designed for improved airflow in all riding conditions.
• Compact, flat radiator fan is lightweight and provides efficient cooling.
• Gear-driven balancer reduces vibration and drives the water pump.
• Eight clutch plates provide the surface area necessary to handle the engine's massive torque.
• Durable five-speed transmission with low ratios designed for racing applications and trail use.

Chassis/Suspension

• Round-tube steel frame with removable aluminium subframe is lightweight and durable.
• One-piece, cast-aluminium swingarm for light weight, maximum strength and durability.
• Independent, double-wishbone, double A-arm front suspension with fully adjustable Showa shocks provide 215mm of travel, and features rear-facing reservoirs for increased durability.
• Pro-Link® Rear Suspension with fully adjustable Showa piggyback shock provides 237mm of travel.
• Dual 174mm front disc brakes with twin-piston callipers and high-pressure front brake lines provide excellent stopping power.
• 190mm rear disc and beefy single-piston calliper provide improved stopping power and increased ground clearance.
• Aluminium brake callipers and brackets front and rear reduce weight.
• Removable aluminium rear grabrail and front bumper for reduced weight.
• Lightweight aluminium wheels reduce unsprung weight for outstanding handling.
• Dunlop radial tires provide superb traction and cornering ability.
• Durable and lightweight O-ring-sealed drive chain.
