Smaller front sprocket + Traction Control question
Looking for some serious knowledge here about how Traction Control works.
Last Saturday, we replaced my brother's V2 (2016) front sprocket from the stock 17 to a smaller 16 teeth. The bike feels smoother on low speeds, plus acceleration feels stronger. So far, we are happy with the results.
However, when the bike is set to Traction Control 2 (most sensitive setting) the TC light will turn on frequently, with the smallest of bump in a paved road.
Trying to explain this issue, I've considered this:
- Speed sensor is in the front wheel.
- The computer is always monitoring speed + RPM and current gear.
Let's say the bike with the OEM 17t sprocket in 2nd gear at 3000 RPM is supposed to move at 50 km/h. (example figures only).
With a smaller front sprocket, (16t) the engine must be at 3200 RPM to match the 50 km/h.
(The same would happen if you installed a smaller rear wheel)
My guess is that the computer might consider the higher RPM as a rear wheel spin and TC is activated.
Your thoughts will be very appreciated.
I is poor doge... I no know bikes!
