Q. I am 5.7 ft which will suit my height r15v3 or mt15?

Both Yamaha MT-15 and R15 V3 accommodates riders well, however, at 810mm, the seat height of MT 15 is 5mm lower than the R15 and should be accommodating for most. For a better understanding of compatibility and riding comfort, we would suggest you to take a test ride. Follow the link and select your desired city for dealership details.
