so gray have we come to any conclusions yet? they just sent my flywheel from TT yesterday so it won't be here t'ill weds so i can weigh them,i'm gonna be a little ticked off if its only a +1 Funny you should ask. I just got the response I was waiting for from some who should know: Doug Dubach. It would seem I had some BAD INFORMATION Whatever the rotating mass the marketing types were talking about that was supposedly increased (if it happened at all) it was NOT the flywheel. Or the cranks either, for that matter. One of the staff at Dr.D remembers that reference, too, but has no idea what it means. I put that together with something else I heard and I have, just as you said, been misleading people with the incorrect assertion that the '04 flywheel was heavier than the '03. They're not. I hate making mistakes like that, but you can't just bury them in the back yard, either, can you? BTW, I'm pretty sure the flywheel is going to weigh more than 2.2 pounds, so look around for a bigger scale. On another note, I'm trying out a GYT-R 5oz myself this week. After riding the Off-road I picked up, I decided it was a little more than I wanted. I got this one cheap and we'll see about it next.
