• A-mode enhances throttle response allowing riders to enjoy even sportier engine performance
• B -mode offers softer, slower throttle response well suited for wet or slippery riding conditions

• works in conjunction with the YCC-T system & utilizes same wheel sensors as ABS system
• when system senses rear wheel spin it intervenes in the following order:
  1) retards ignition timing,
  2) modifies / limits fuel injection duration
  3) closes the throttle butterflies via YCC-T to reduce power until wheel spin matches the chosen setting
• 6 modes plus off: minimal to maximum intervention as per rider choice. Maximum intervention is well suited for slippery conditions.

• maximizes engine performance & centralizes mass for light, agile handling
• header pipe diameter & length have been optimized for optimum flow
• System features three, 3-way honeycomb catalyzers to reduce exhaust emissions. The oxygen sensor provides feedback to the ECU so it can adjust for the optimum fuel/air mixture. The “mid ship” titanium muffler is located low in the chassis to central mass & lower the center of gravity for incredible handling.

• part of the mid ship exhaust system
• utilizes a titanium body & butterfly valves that reduce the “blow back” phenomenon caused by “valve overlap”
• design reduces weight & maximizes cornering clearance
• EXUP system helps eliminates “flat spots” in the power band & reduces emissions

• MotoGP inspired innovation that Yamaha calls a “straight frame concept”, meaning top spars of the frame lie as close to possible to the frame’s torsional axis (the line connecting the head pipe to the swingarm pivot point).
• ram air duct passes through the frame at the head pipe for a straight ram air effect
• mix of mold castings & pressed aluminum plates make up the frame

• aluminum disc carriers reduce weight
• Nissin master cylinder provides excellent front brake lever feel & feedback

• controlling ECU & hydraulic unit are combined into a single compact unit to reduce weight & centralize mass

• ABS benefits include; excellent control under hard braking or when braking on wet, slippery or loose surfaces

• reduce unsprung weight by making hub & spokes a single structural unit
• special casting technique makes the rim section substantially lighter & stronger

• system must recognize the “coded ignition key” in order for the unit to start
• if immobilizer ignition does not recognize the key, the ignition system & starter will not function, even if the ignition is forced into the on position

• CCU is Yamaha’s data acquisition unit… a great tool for track day & race enthusiasts
• works with IOS & Android platforms
• parameters recorded include: traction-control activation, front & rear ABS activation, lean angle, engine speed, wheel speeds, throttle position, gear position, front & rear brake pressures, coolant temperature and lap times
