Re: good news and bad news
Do you ride mostly on the road? If so, an R1 is easier to ride simply because the power band is so strong and wide -- you won't be constantly working the gear box. It's way more than you could ever legally use though. Even a 600 is that.
But if you go to the track, the R6 is the bike to have. Especially if you wanna race. The R1 is prone to spin the rear wheel and from reviews anyway, doesn't turn as sharply or with as much confidence as the R6.
I'm a big guy but if I were a normal size guy, I would have gone for the R6 in a heart beat. I do most of my fast riding at the track these days. But, for me it was either an R1 or a GSXR750. The R1 presented itself and that's what I got. To be honest, I don't think the OEM suspension on the R1 is as good as the GSXR, not for my size anyway.
