You cant really hit the ton on Indian roads, maybe some these days, but I would not recommend it. wanting a faster engine does not necessarily mean I'd always be taking it to its limit. I would have the comfort of cruising at 70mph without all the vibrations that an enfield 350 gives you at the same speed.i have a 1982 cb450t hawk which is the same bike with a few updates and a lil bit bigger engine while im sure it could hit 100mph if i really wanted it too ive have never tried; i would worry less about "doing the ton" and just make sure the bike is running good and well maintained. That being said my bike will get up to 80mph pretty quick but above that seems to hit a wall; you'll hit a hundred but it'll take awhile. Never had much of a desire to go that fast on public roads; also should add that my speedometer goes to 110 mph
