Features
• Adjustable Engine Maps: two-mode adjustable engine mapping allows the rider to adjust engine character with the push of a button, making it easy to make immediate adjustments to changing track or weather conditions
• Wraparound Rear-Positioned Exhaust Layout: innovative exhaust pipe design improves mass centralization and power development characteristics; this layout moves the rear end of the exhaust pipe farther forward and positions the muffler closer to the bike’s center of mass
• Sleek air cleaner cover provides tool-free access to the air filter, positioned at the front of the bike to avoid roost from the rear wheel
• Power Tuner App puts the flexibility and precision tunability of the GYTR Power Tuner into your smartphone: adjust air/fuel mixture and ignition timing maps instantly and upload them to the bike for ultimate track-side tuning; record race log information and monitor a range of data such as maintenance and system diagnosis, engine run time and more; wireless connectivity to the bike’s onboard CAN-bus network
• Monster Energy Yamaha Racing Edition features a striking color and graphics package that stands out at the track or on the trail
