produces a strong spark for fast starts
-
provides precise ignition timing / mapping for optimum engine performance at all rpms
High performance direct ignition coils.
-
ignition coil is built directly into the spark plug cap
-
significant weight reduction
Yamaha Chip Control Throttle (YCC-T).
-
YCC-T electronically controls throttle valves for outstanding throttle response & controllability
-
YCC-T system provides precise control of intake air volume for a smoother torque curve
-
ECU that controls YCC-T is capable of responding to changes at a speed of 1000th of a second
Yamaha D-Mode variable throttle control … 2 modes available.
-
works in conjunction with the YCC-T system
-
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 & power
-
T-Mode slows throttle response for situations that require softer power characteristics, such as slippery or wet conditions
-
"T-Mode" is well suited for more relaxed touring & reduces fuel consumption
Traction control system
-
works in conjunction with the YCC-T system
-
utilizes front & rear wheel sensors (same sensors as ABS system)
-
system senses when the rear wheel begins to spin & modifies the YCC-T function, ignition timing & 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.
-
also part of the YCC-T family of functions
-
"settable range" is from 50 to 160 km/hr & transmission must be in 3rd 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 activation button
-
control buttons are located on the L.H.S. handlebar switch gear
Closed loop Mikuni, 42mm, throttle body fuel injection system.
-
crisp, seamless throttle response regardless of weather or altitude
-
system uses throttle position sensor (TPS)
-
4-hole Denso injectors
-
"closed loop system" uses a heated oxygen sensor to "sniff" spent exhaust & automatically adjust the fuel / air ratio for reduced emissions
-
heated oxygen sensor provides precise fuel - air ratio information, especially at lower engine temperatures
-
fuel injection benefits include choke-free starting, steady idling during warm up, excellent fuel economy & reduced emissions
Viscous paper-type air filter.
Compact engine uses a stacked "Tri-Axis" design.
-
stacked design reduces engine length & centralizes mass
-
design allows the engineers to place the engine in the "sweet spot" of the frame
-
optimized front & rear weight distribution for excellent handling characteristics
New 6-speed transmission with revised gear ratios.
-
New 6th gear for more relaxed, higher speed cruising … engine rpm is reduced in top gear
-
transmission features new helical gears & separate gear dog design
-
design keeps the transmission compact & quieter too (helical gears)
-
revised gear ratios optimize the FJR's wide spread of power
Special "scissors-type" primary driven gear.
-
reduces drive train backlash
-
reduces transmission noise
New hydraulic clutch with slipper & assist functions.
-
slipper clutch function reduces the negative effects of engine braking on handling & suspension
-
assist function reduces clutch lever effort by up to 20%
-
hydraulic design provides smoother operation & requires less maintenance
Clean, quiet shaft drive.
-
shaft drive system is super-durable & low maintenance
-
system features mechanical cam dampers in the drive pinion for quieter, smoother power delivery to the rear wheel.
Curved radiator uses twin "ring-type" cooling fans.
-
excellent heat dissipation … curved rad offers more cooling area than a flat rad
-
special air management moves hot air out of the cockpit area to reduce heat to the rider
-
ring type fans "pull" more air than a conventional type fan
Easy-access spin-on oil filter & drain plug make oil changes fast & easy.
