Yamaha R25 top speed 173 kmph on Sentul, 196 kmph on Dynojet – Video
Yamaha R25 thus far is known to reach 173 kmph top speed via speedo pictures and blog reports. Here is a video of R25 bikes charging and leaning on Sentul International Circuit, Indonesia, where speedo indicating highest velocity is zoomed in to prove.
Further, here is a video showing Yamaha R25 touching 196 kmph mark during dynamometer test. Dynojet 250i machine tests Yamaha R25’s power and torque behaviour against engine speed, among other parameters including top speed. Difference of 23 kmph on dynamometer comes from lack of wind resistance (drag), asphalt friction and similar factors that drain a motorcycle’s power on road. Report of same was posted earlier.

Instrument cluster is sporty and functional with features like gear position indicator, shift timing indicator light, FI diagnostics, timer, engine temperature warning, oil change indicator, fuel consumption indicator, tripmeter and odometer.
