What is the function of the T switch on the Honda CBR650R handlebar?

The T button on the Honda CBR650R handlebar is a traction control switch that requires a long press to operate. Below is an introduction to the Honda CBR650R after its facelift: 1. Engine: To pursue the smoothness of the inline 4-cylinder engine in the original CBR/CB650F at high RPM, the piston shape was redesigned, and the compression ratio was increased by 0.2 to 11.6. The cam profile was modified to increase the overlap time of the intake and exhaust valves, boosting the horsepower from 90ps to 95ps and raising the RPM from 11,000rpm to 12,000rpm. 2. Chassis: The difference between the CB/CBR650R and the previous generation lies in the chassis components and frame. The chassis components feature inverted front forks, radial calipers, and aluminum alloy wheels, successfully reducing the weight of the front and rear wheels by 970g to achieve the goal of lightweight. The frame was adjusted using analytical technology.
I'm so familiar with this T switch. Anyone who rides a Honda CBR650R knows it controls the dashboard information display. Every time I press it, the screen cycles through the total mileage, trip A and B distances, and average fuel consumption. Holding it down can reset the trip meter, which is perfect for calculating how far a full tank can go. Last week when I was riding on mountain roads, I could easily switch to check real-time fuel consumption with my right hand without even looking down for the button. Actually, for daily commuting, I use Trip A the most to record work mileage, and Trip B for weekend trips. I remember when I first got the bike, the manual mentioned it could also adjust the clock, but it required combination with other buttons. The position of this T button is really well-designed—my left thumb can reach it perfectly, and operating it while riding doesn't interfere at all.
As a veteran mechanic who often works on Japanese motorcycles, I've disassembled the T-button on the CBR650R numerous times. It's simply a trip switch with high-quality metal contacts that resist aging well. The top-left handlebar placement is brilliantly designed for glove-friendly blind operation. Its most practical feature is the fuel consumption display - diagnostic tools reveal it uses real-time ECU calculations. Some customers complain about unresponsive presses, usually because they confuse short-press (cycle) with long-press (reset). I always teach apprentices: this button connects to the dashboard wiring harness - water ingress during rain often causes poor contact. Last month, I fixed a case where sticky buttons caused screen glitches.
