Kawasaki Ninja 1100SX price in Kasaragod

I am trying to choose between the Kawasaki Versys 1100 and Ninja 1100. My usage will include daily office commutes, weekend solo rides, and occasional 500-600 km touring trips with my wife and some luggage. I had brief test rides of both, and these were my impressions: Versys 1100: Extremely comfortable for both my wife and me. However, at 175 cm tall, I could not flat-foot it completely and found it intimidating in city traffic because of its size and weight. Ninja 1100SX: Not quite as comfortable as the Versys, but still comfortable. My wife found the pillion seat comfortable and did not slide into me under braking. I liked the handling very much and found it far easier to manage in city traffic. However, I suffer from occasional lower back pain, so I am concerned whether the slightly leaned-forward riding position might become an issue on longer rides. I want something powerful, smooth, easy to handle in city traffic and also good for a long tour on the highway. I do not plan to do off-road stuff. Also, the lower the weight to handle, the better it would be for me. I would often like to use this bike daily in the city, also being usable in Indian bumper-to-bumper traffic. Also, do note that in the past, I have tried one of my friend's 2025 Z900 and rode it for a full day and had back pain by the end of the day. So I don't want that thing to happen to me with the bike that I shall buy. Please suggest one which shall suit me best?

I own a V-Strom 650 with about 50,000 km since 2022. The bike is great, but it has a buzz and vibrations around 100 km/h that disappear after 120 km/h, yet I typically cruise around 100 km/h. I want to upgrade to a 1000cc+ bike for highway touring with a seat height under 835 mm. I am considering the Kawasaki Versys 1100 (2026), BMW XR, and the BMW R 1300 GSA. My priorities are long-term ownership, riding comfort on Indian roads (including routes like Spiti), ease of maintenance, and strong road presence. Please advise.
