Just take a new o ring or (less so) x ring out of the box, the stiffness is staggering, I'd say that it would easily consume 4-5hp! That's probably not even noticeable on a 150hp modern bike... But on a mk111, when you've got less than 40 to begin with...andychain said:Why do you think racers avoid it.
If you ride daily in all weathers then an O ring is fine for fair weather
use a good non O ring.
As for old Brit bikes they shouldnt have O ring....they never did from factory
and there were few problems.

Sorry Andy, have to correct on this one. A friend was at Laguna Seca this summer and spent a lot of time with the pit crewsand racers like Danny Pedrosa and the other top guys. He has pics of himself standing beside Pedrosa and Pedrosa is tiny!
They are all running Xring chains on their MotoGP bikes. They toss them after one race. He brought home the 520 x ring from Cal Crutchlow's bike. We checked it against a new 520x ring and the length was identical, so he will run it on his Vincent, probably for 20,000 miles or so.
