No merrcy to drive R15. Review on Yamaha R15

Hello everyone today I am give you real reviews of R15 bec I have tested this bike. It is well for short distance and for riding a sports bike. People who love riding this bike will never make them nervous but if you are looking for comfort then this bike has not comfortable for long drive. Although the yamaha is one of the trust band in our county the legend bike like yahama rx 100 & rx 150 were the top favourite bike of bike lover. But yamaha R15 is not satisfied me although bec of it comfort I have drive this bike for approx 400 km all journey but hand and riding was to good. I have rech this bike at speed of 120 there was no sound and riding this bike was quick good and the mono suspension was was also really very good at lots of places at night when I was riding I not seen lots of bumper which was quite good I cross. But siting of this bike was really very bad I Got sore Ness in my bump and thigh were paining and sore in felling. After 2 day of ride the rigidly felling in my thigh. And behind me who was sitting he say that I will never sitting behind if you bring this bike again. It my request to the company of yamaha that modified the seat of this bike and make more comfortable for siting on this bike. Over all the bike is good but siting make this bike worst in comfort.
