ENGINE

Slim, compact, 847cc, DOHC, 4- valve, liquid-cooled, 42.5 degree inclined, inline-three cylinder engine. The engine has been tuned to provide plenty of low & mid-range torque with strong yet linear throttle response.

• 4-valve, downdraft style combustion chamber
• excellent torque output... especially in the low to mid rpm range
• 4-valve design maximizes flow into & out of combustion chamber
• 31 mm intake & 25 mm exhaust valves
• valve angle is 26.5 degrees to keep combustion chamber compact
• stainless steel valves feature an Isonite surface treatment & carburized tips for excellent durability & wear resistance

Valve adjustment intervals are every 42,000 kms.

120 degree crankshaft.

• design reduces inertia torque while emphasizing linear torque in response to the rider's throttle action
• design has been optimized to achieve strong torque over a broad rpm range
• fast, linear throttle response
• engine design allows a whole new level of "rider - machine communication"

Lightweight "coupling force balancer" is used to reduce engine vibration for excellent rider comfort.

"Fracture split" connecting rods feature a "nut less" design.

• lower end "cap" of the rod is made from the same piece of material as the upper portion; the 2 pieces are "split" apart using a special fracturing process & then machined
• design aids in establishing true big end roundness & greater precision in con rod dimensions for excellent durability despite the high horsepower loads.

Lightweight, forged, aluminum short skirt pistons.

• design aids in fast engine response
• reduces mechanical vibration

Direct ceramic composite plated cylinder uses "liner less" bores.

• ceramic coating sprayed directly on the aluminum block, eliminating the liner & reducing weight
• excellent heat dissipation for consistent power delivery
• coating enhances the thin film of oil between the cylinder & piston, reducing friction & increasing power

Offset cylinder design.

• cylinder is "offset" relative to the crank (toward exhaust side)
• reduces frictional losses between the pistons and the cylinder wall during the power stroke for improved power output

One-piece cylinder and upper crankcase assembly.

Yamaha D-Mode variable throttle control ... 3 modes available.

• enables the rider to adjust the performance characteristics of the engine based on riding preferences or riding conditions
• standard mode emphasizes very linear throttle & torque feel of the engine
• A mode allows the rider to enjoy even sportier engine performance in the low to mid rpms
• B Mode reduces throttle response for riding situations that require softer power characteristics, such as slippery or wet conditions
• D-Mode button is conveniently located on the RHS handle bar switch gear

Traction control system with 2 modes plus off.

• mode 1 provides mid-level intervention (allows some wheel spin)
• mode 2 provides maximum intervention (no wheel spin)
• works in conjunction with the YCC-T system (utilizing same wheel sensors as ABS system)
• system senses when the rear wheel begins to spin & modifies the YCC-T function, ignition timing & fuel injection volume to reduce power & eliminate wheel spin
• status indicator / warning light in meter assembly

Electronic Control Unit (ECU) utilizes a powerful 32-bit processor for fast control of the injection, engine management & ignition processes.

Air box features dual resonator chambers & unequal internal intake funnel lengths for all 3 cylinders.

• benefit is a wide torque curve & exciting intake sound that accentuates the exhaust note
• viscous paper type air filter is used

Compact 6-speed transmission.

• gear ratios are optimized to accentuate the torque & throttle response of the engine

Compact, slipper (back limiter) clutch with assist.

• slipper clutch reduces the negative effects of engine braking on handling & suspension
• reduces rear wheel hop/ chatter when decelerating for improved riding performance & smoother corner entries
• assist function reduces clutch lever effort by up to 20%

Accessory quick shifter ready.

• allows for faster upshifts by eliminating the need to close the throttle or pull in the clutch
• works with standard shift pattern
• reduces wear & tear on the clutch & transmission
• easy plug-and-play installation (part number: BS2-E81A0-V0-00)

Revised, compact, low mounted, 3 into 1 exhaust system.

• stainless steel header pipes with special "Nano-film" coating

• low mounted design centralizes mass for excellent handling & light weight feeling
• revised muffler cover & end cap for improved appearance

Flat design radiator with new side scoops.

• protector plate on lower edge of rad prevents small stones from hitting the rad & cooling fan
• new side scoops direct air into rad plus adds a styling protector plate on lower edge of rad prevents small stones from hitting the rad & cooling fan

Wet sump lubrication system with liquid-cooled oil cooler & easy access drain plug & oil filter.

• liquid-cooled oil cooler maintains stable lubricant temperatures for extended engine life
• easy access spin-on type oil filter & drain plug for fast oil changes

Maintenance-free transistor controlled ignition (TCI).

• produces a strong spark for fast starts
• provides precise ignition timing / mapping for optimum engine performance at all rpms

Air Injection System (AIS... not ram air) injects fresh air into exhaust ports to fully burn any unburnt fuel, reducing exhaust emissions.
