I owned an 05 R1 for less than 1 season and sold it. Good peak horsepower for sure, but I wasn't on the track keeping it at peak and found it useless on the street. I hated it compared to my carburated R1's. I bought it for the looks with large expectations from the engine, which just fell flat on it's face IMO.I'm with you on the old R1. I have one too. Still faster on a race track than my Ducati.
It's awesome making the move from multiple inline 4's to the 1098s. I owned a 97 TL 1000 for a couple months in 98 before getting rear ended on it. I guess I forgot about the grin factor generated by twins. I rode a buddies highly moddified 04 RC on the track but it just doesn't deliver like the engine on the Ducati.
