Comprehensive Electronics Package

The interesting element to the new R1 is the little black box and what it does for the experience. Yes, Yamaha has decided to come to the electronics party. It introduces a 6-axis Inertial Measurement Unit (IMU), the first of a great number of TLA’s (Three Letter Acronyms).
Yamaha says the box gives the new R1 Total 3D controllability. What this means is that the box has 3 gyro sensors  to measure pitch (forward – backwards during braking and acceleration), Roll (a lean angle sensor) and Yaw turning left and right (slide). It also has three G-sensors to measure acceleration in pitch, roll and yaw.[/text_output]

If you can’t beat em, join em. The clever box of tricks analyses the data from these sensors 125 times a second, to work out what the bike is doing in any given moment, and apply the required amount of electronic aids to help the rider a) Go faster, b) Not Crash c) Get the rear tyre spinning up (a little).
Yamaha R1 has a Traction Control System (TCS) which works off the differential speed of front and rear wheel sensors, a Slide Control system (SCS), which uses the Yaw element of the 6 axis controller to work out when the rear is stepping out. SCS works in conjunction with the Traction Control, which limits the amount of throttle the rider can apply when the bike is leaned over, as more of the available grip is being used for cornering.

We also have Front LIFt Control system – LIF (?), aka anti wheelie, Launch Control System (LCS) which limits the revs to 10,000rom even at full throttle. It won’t help keep your clutch in good condition however. Needless to say LIF and LCS will work together to get you off the line as smoothly as possible.

The R1 also comes with a quick shifter as standard, the Yamaha QSS or Quick Shifter System. The power mode selector (PWR) switch builds on the D-Mode system of the previous bike, and has four different engine maps. There is also a preset mode called YRC, or Yamaha Ride Control system, where a rider can select from 4 preset settings which have the bike setup how you like it (see photos at the bottom for the switchgear to operate these).

Optional equipment is a Communication Contol Unit (CCU), which is effectively a datalogger for track and racing use, and which is wifi enabled.
