2 Answers
Yamaha malfunction indicator light can be reset by using a professional diagnostic computer. Taking the 2020 Yamaha model as an example, it belongs to the scooter category with the following specifications: length 1800mm, width 685mm, height 1050mm, wheelbase 1275mm, fuel tank capacity 5.1L, and curb weight 90kg. The 2020 Yamaha model features front and rear tire specifications of 90/90-10 50J, equipped with a front single disc and rear drum brake system. It delivers a maximum power of 6.1kW and a maximum torque of 9.7Nm, with a continuously variable transmission (CVT) and belt drive system.
I've been riding a Yamaha motorcycle for several years, and the check engine light usually comes on due to sensor or electronic system issues. The safest way to clear it is to visit an authorized service center to erase the fault codes with diagnostic tools, but this is just a superficial fix. If the root cause isn't addressed, the light will keep coming back. For example, my bike once had the light on because of a dirty oxygen sensor. I disconnected the negative battery terminal for a few minutes to temporarily turn it off, but the real solution was cleaning or replacing the part. Don't forget to check battery connections and throttle body cleanliness—these minor maintenance tasks can reduce the risk of faults. If the light comes on, never force the bike to run; getting it checked by professionals is the best approach to avoid hidden major issues that could damage the bike or compromise safety.
