I have low back listhesis and ride about 80-100 km per week. The roads I use have potholes and rough patches. Please suggest a smooth bike that won’t aggravate my back. I’m 52 years old.

I'm planning to purchase my first motorcycle and have narrowed down my options to the Bajaj Pulsar N160 SS and Dominar 250. My primary usage will be short daily commutes of approximately 5-6 km one way in Hyderabad's traffic (around 12km two way), with occasional longer rides. I'm a relatively new rider, so low-speed usability, manoeuvrability and ease of handling matter to me. The N160 SS appeals to me because of its lighter weight, Crawl Tech, TFT and city-friendly characteristics. However, the Dominar 400 has been my dream motorcycle for the past ten years, ever since it was launched in India while I was still in school. While the Dominar 400 remains my dream bike, the Dominar 250 seems like a reasonable compromise for my primarily urban use, offering some of that Dominar experience without going straight for the 400. I've ridden the Dominar 400 and found it surprisingly manageable and planted, but I haven't been able to test-ride the Dominar 250 because dealerships don't have test-ride units. I've also heard that the Dominar 250 lacks low-end urgency, requires frequent gear changes in slow traffic and is relatively heavy for city use. On the other hand, my uncle, who has owned a Dominar 400 for years and uses it in Hyderabad, has suggested that the Dominar 250 could be a reasonable choice for my requirements. The Dominar 250 is currently quoted at approximately Rs. 2.42 lakh (on-road), compared with around Rs. 1.86-1.94 lakh for the N160 SS. Given my usage, beginner experience and long-standing desire to own a Dominar, would you recommend the N160 SS as the more sensible long-term choice, or is the Dominar 250 a motorcycle that I could realistically grow into and enjoy despite its compromises? I would particularly appreciate your thoughts on low-speed tractability, bumper-to-bumper traffic, manoeuvrability for a beginner, and whether the Dominar's additional weight and cost are justified for someone whose riding will primarily be urban.
