The cooling system of YBR engine is much impressive as the tank wings/airscoop also throw air direct on Engine so the engine gets air from all sides causing a better cool engine with better acceleration.
As far as the mirrors are concerned; these are not only cheap we should say these are the Cheapest mirrors which were being used in the old YAMAHA 100 motorcycles but one thing I would like to mention here that these mirrors are not cheap than the AHL Mirrors. The mirrors on my previous bike Pridor was so cheap that I have to install my old YAMAHA 100?s mirror on it. When I sold my Pridor at that time I installed the AHL Mirrors on it.
The battery was Okay in my case but I should mention here that:
When I asked the dealer that have you charged the battery. His answer was very interesting which I was not expecting:
His answer was that "We fill in the battery fluid (acid) provided with the new battery and put it aside for some time. Then the battery charges automatically." Hahahahahhhaa.
I did not asked more but on reaching home I dismantled the battery and get it properly charged then reinstalled it in my YBR.
