- Low- vibration crankshaft.
• carburized connecting rods for excellent strength & durability
- Dual axis gear-driven secondary counter balancer.
• reduces engine vibration for enhanced rider & passenger comfort
- Automatic cam chain tensioner.
• reduces both maintenance & engine mechanical noise
- 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
- 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
• 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.
- 4-into-1-into-2 stainless steel exhaust with new catalyzers.
• optimizes engine performance across the power band
• new dual, three-way catalytic converters reduce emissions
• the FJR1300 meets or exceeds EU-4 emission standards
- Excessive lean angle cut-out switch prevents the engine running in the event of a tip over.
