What is torque of Benelli TNT 600?

First you tell me what is your purpose if you need sound and you like a L line 4 cylinder engine then my suggest is you go for benelli 600i otherwise as a bike performa Ninja 650 is better than benelli 600i

I haven’t clocked the 0-100 time but I think it’s somewhere between 4-5 seconds. As for the mileage, with the ixil xtrem60 exhaust and bmc air filter it’s between 14 to 15 in city and 17 on the highway with pretty aggressive riding.

TNT 600i is a street bike and you can't do offroad in 600i because it doesnt have a good suspension.You can do long rides it depends on the rider. As a owner I suggest you to go with it if you want a street bike in that price range and if you need a touring bike in that price range you should go with Kawasaki versys or Benelli trk 502.

No, the bike is low on any of the modern features and the price point except 4 cylinder engine and sound and build quality nothing is special.

My height is 5.3, i can hardly reach the ground. I don't own a 600i but did a test ride. Its a bit hard to control the bike but i guess i can managed after a while. But won't be as manageable as an average of 5.7 or above person. I guess a 5.5 person will be able to manage the bike too, but it may take a while to get used to. Just do a test ride and see for yourselve.

It’ll cost you anywhere between 4-6k for your first service

Yes yes of course I think so
