Yamaha R25 reaches 196 kmph top speed on dyno test

Yamaha R25 was tested on a Dynojet 250i dynamometer recently in Indonesia and the results were puzzling. As evident in the picture below, Yamaha R25 reached 196 kmph top speed without wind resistance and asphalt friction. But power and torque figures measured by the dyno come as a surprise.

On road, as we saw earlier, Yamaha R25 is capable of achieving 154 kmph at 11,000 rpm and top speed of 173 kmph at 12,500 rpm. YIMM has not specified their top speed claim yet. We sure know it beats Honda CBR 300R in this subject for now. Shall hear more about competition between them once both bikes become available on road.
