I own a Thunderbird 350 and I have clocked around 14000 km in 6months and still cruising with no problems so far. Following were the pros and cons I experienced as a TB owner.
Pros:
Royal Enfield is the oldest motorcycle brand in the world still in production with the Bullet model enjoying the longest motorcycle production run of all time.(Src: Wikipedia). It should have something good going on if it stood the changing tides of time.
- Thunderbird is very comfortable and Id recommend it if you do a lot of cruising.Thanks to the Large seat and the great suspension. I have driven my bike around 610kms straight from Doodhsagar waterfalls, Goa to My home in Calicut, Kerala with just one fuel stop(and for that too I didnt get off my bike) and reached home with a very minimal backache.
Bikes like duke arent actually meant for cruising and hence their seats are very hard and you get back pains easily. In addition to this, my wrists usually hurt after riding duke, NS etc, but I dont find any such problems with my TB. And it is also one of the best handling cruisers.
