This is a real hard question to answer. For starters, most people, myself included are only giving educated guess'. The thing is this, there are way too many factors that go into top speed. Things like snow conditions, air temp, density, rider weight, wind, on and on. So, what one guy claims may differ from the next guy simply by location etc. The next thing is, many guys talk a big game about how fast they go, truth though is most don't go WOT for very long. Don't know about you but, in the various parts of Ontario where I ride, there is only the lakes to ride fast on. Problem is, with uneven terrain, I start to lose my comfort feeling at around 90mi/hr. Now how fast that really is? don't know, didn't have a radar trap. Look at it this way, if you took the top muscle sleds from each company, made all things equal, amount gas, rider weight, studs, etc, etc, I think you would find it is pretty close between them. You may see a spread in who gets to max speed first, but at the end of the lake, a few feet here or there maybe. Going back to what I said before, it takes a big set of cahoonies to hold on WOT for an extended period time. Wish ya luck!
