Q. I am a 5.4 feet guy would i be able to ride this bike?

The Seat height of R15 V4 is 815mm. The V4 looks different, its dimensions, including the seat height and wheelbase, are identical to the V3. So, unsurprisingly, pillion comfort is unchanged as the lower position for the stepped seat is maintained here too. However, the rider will be more comfortable here. The clip-on bars are positioned slightly higher and are now angled flatter, giving you a more relaxed seating posture which will prove valuable for everyday use and for longer rides. Moreover, comfort is something that can be best judged personally and varies from person to person. Also, we would suggest you take a test ride before making the final decision.
