Yamaha R15 is not good enough.
I used it for 2 years and my experience says that you should not buy this.
Because its comfort is really bad. When you drive it for more than 20-25 km your back will start to pain.
Mileage is really bad 15-20 km only.
It is not reliable bike.
Road grip is good even on wet surface.
The only this I like in this bike is its Design and structure and nofhing else.!
