I am planning to buy Yamaha R15S. I will be riding it 40 kms a day in city traffic. I have below questions.
1) Will it be comfortable for this daily commute?
2) Although it has single seat, is it comfortable for pillion rider (especially elder people)?
3) Does it cause any back and wrist pain over a period of time because of sitting position?
4) What about the handling of the bike in city traffic?
