During the media launch of Yamaha’s significantly updated R6 at Thunderhill Raceway, the bikes were fitted with the GYTR Communication Control Unit (CCU) first available on the high-end YZF-R1M. This electronic device logs data incorporated from a GPS sending unit and the bike’s ECU that allows riders to analyze braking, throttle position, gear indication, as well as other data that can be helpful in evaluating performance of both bike and rider.

2017 Yamaha YZF-R6 First Ride Review

The GYTR CCU can be added to the 2015 R1, 2016 R1S, and 2017 R6 in a plug-and-play installation and allows users to interface and download data logs directly to their mobile device. Using the Yamaha-Telemetry Recording and Analysis Controller (Y-TRAC), the CCU allows riders to see their position on the track or street when reviewing their ride. The following 11 data channels are available for analysis, helping reduce lap times and increase performance to the next level:

  • Engine rpm
  • Throttle-grip position (degrees)
  • Actual throttle opening (degrees)
  • Rear wheel speed
  • Front wheel speed
  • Transmission Gear position
  • Rear brake pressure in BAR (1 BAR = 14.5 psi)
  • Front brake pressure in BAR (1 BAR = 14.5 psi)
  • Engine coolant temperature
  • Ambient air temperature
  • Fuel usage (real time in gallons or cc’s)
The GYTR Communication Control Unit for YZF retails at $699.99.

Y-TRAC can also work in conjunction with TCS and ABS, indicating the timing and duration when TCS or ABS is activated.

If you plan to use the CCU on the street, the app has functions to allow you to record your route, as it will place it into the same layout as if you were at the racetrack. Find yourself heading to your favorite canyon every weekend? The app will allow you to track the route and then record the data the same way it would around a racetrack. On the track, riders will be able to choose a higher sampling rate in which data is recorded (10 Hz) or a lower rate (1Hz) for street applications. And if your track/route is in the middle of nowhere, it can be configured at home prior to heading out.

Installation is simple; everything you need to install the module is included and will work with the standard passenger seat or accessory rear seat cowl in place. After fitting the module to your motorcycle, you will need to download the app from your appropriate app store. Android users will have the two; Y-TRAC and CCU Config to download as they are separate, while iOS users will download the Y-TRAC app only, as it includes the CCU configurator. Apple users take note: the app is only supported on iPad devices. The plug-and-play module then connects to your device via a built-in wireless network. Once connected, the app’s user interface is intuitive and easy to use.
