The '09+ R1 is probably the only new Japanese pure sportbike I would consider buying new. Everything else is just more of the same, while the R1 is unique. Reliability seems excellent for them as well, it seems Yamaha really did a good job with the bike. Some may say it is heavy, but it is all relative (I could also lose a few pounds).
The '06 R1 LE is cool too, but mainly because of its looks and bling factor.
