- classic air-cooled V-twin engine appearance
- each cooling fin is specially machined to create a styling highlight
Dry sump oil lubrication system.
- oil tank is integrated into left side of rear sub frame to reduce weight
- dry sump system reduces engine height (no deep oil pan), which lowers the centre of gravity for great handling and a light, agile feel
- easy access, spin-on type oil filter for faster oil changes
Air-cooled oil cooler.
- maintains stable oil temperatures for optimum lubrication and extended engine life
Closed-loop, single-body, Mikuni throttle body fuel injection.
- system uses a single throttle body with a throttle position sensor (TPS) to help optimize intake air flow
- 12-hole injector maximizes fuel atomization and features a dual spray pattern for more complete combustion chamber filling
- "closed-loop" system uses dual oxygen sensors to "sniff" spent exhaust gases and automatically adjust the fuel / air ratio for reduced emissions
- oxygen sensors are located before the mufflers, so the use of aftermarket "slip-on" mufflers will not affect the system
- fuel injection benefits include choke-free starting, steady idling during warm up, excellent throttle response, better fuel economy and reduced emissions
Large-capacity airbox.
- airbox intake duct is located inside the right-side middle fairing for a good flow of fresh, cool air
- high capacity, viscous type paper air filter
Ride-by-wire Yamaha Chip Control Throttle (YCC-T) system
- YCC-T electronically controls throttle valves for outstanding throttle response, controllability and a smoother torque curve
- YCC-T features a DC-motor-driven throttle valve for precise control of intake air volume
- Cable-free design (no throttle cables, pulleys, etc.)
- ECU is capable of responding to changes at a speed of 1/1000 of a second
Yamaha D-Mode variable throttle control (2 modes available).
- enables the rider to adjust the performance characteristics of the engine based on riding preferences or riding conditions
- S-Mode allows the rider to enjoy full engine performance and power
- T-Mode slows throttle response for situations that require softer power characteristics, such as slippery or wet conditions
- T-Mode is also well suited for more relaxed touring and reduces fuel consumption
Yamaha traction control system.
- utilizes front and rear wheel sensors (same sensors as ABS system)
- system senses when the rear wheel begins to spin and modifies the YCC-T function, ignition timing and fuel injection to reduce power and eliminate wheel spin
- traction control helps maintain traction when accelerating on slippery surfaces
- system is automatically engaged when the ignition is on (can be turned off if desired)
Electronic cruise control system.
- cruise control can be set between 50-160 km/h, in third gear or higher
- cruise control can be cancelled by activating front or rear brakes, pulling in the clutch, completely closing the throttle grip or using the system setting buttons
Smooth-shifting, 6-speed transmission.
- optimized ratios take advantage of the engine's massive torque for strong acceleration and less shifting
- low 1st gear makes pulling away from a stop easy, while 5th and 6th gears are overdrive gears for reduced engine rpm at highway speeds
- engine spins at approximately 2,750 rpm in 6th gear at 120 km/h
Heavy-duty, hydraulic assist and slipper clutch.
- assist function reduces clutch lever pull by 20%
- back torque limiter, aka "slipper clutch" reduces the effects of engine braking when downshifting or decelerating
- low maintenance, self-adjusting hydraulic master cylinder provides smooth clutch lever operation
Low-maintenance, belt drive final drive.
- cleaner and quieter than chain drive with no messy chain splatter
- more efficient than shaft drive due to minimal power losses
- significantly reduces maintenance vs chain or shaft (no regular adjustments or lubrication required)
