Q. Can I go for long rides with my wife on Kawasaki Vulcan S?

Yes, me and my wife always go on rides together. We have completed rajasthan tour of 2500+km in 20 days. Ratlam to dehradun and nearby hill top locations (3000+ kms), Ratpam to pachmari (1500+kms) Ratlam to alibaug, goa and nearby areas ( 3500+kms) Still I will point out few things. The seats (rider and pillion both) of vulcan are bit hard, especially as the width of pillion seat is not enough, it gives lower back and Gluteus. Even for rider seat after few hours even with interval rests, the rider starts feeling stress in lower back, Shoulders, Scapula and Gluteus too. (Usually shoulder and scapula pains started after 10hrs of rides)For that I started using air seats for me and my wife, aditionally we both started using level 2 riding jackets, that gave both of us support on back and shoulders, padded gloves as after long time driving due to vibrations forearms starts to pain.So finally We are riding really good and the longest performed ride of ours with about 32 kg luggage was dehradun to ratlam which took us about 18 hrs (including 10-20 minutes rest about every 1 ot 1.30 hrs.

Sure you can.. Vulcan S is meant for long leisurely rides on highways ( rather than weaving through bumper to bumper City traffic ). I got my Pillion backrest made by Dochaki Customs, Pune which provides added comfort to the pillion.

Absolutely. Adding a backrest for the pillion makes things significantly better though.
