Been using my R1 as a track bike for the last 2 years really, been through a few colours and exhaust/setups in that time but really pleased where it is now.
Just got back from Cadwell park, did Spain again in May too which is always fun.
as to the distance to tracks putting people off, i have more fun in 1 session on track than a whole year of road riding if i did it anymore, regardless of the drive, after the first session it's always worth it, unless it's raining and you forgot to bring wets.. then it's crap
Here's some pics of the bike and some onboard from Cadwell before it started hammering down.
R6 looks great btw, loved my 05 5SL.
Just a word of warning with the 5EB R6s, they love to crack the liners, if it starts cutting out when warm do a compression test, most if not all of them suffer with it at some point, there are companies that will reline them, but normally cost more than the bike is worth.
A few mates run them as track bikes and have had great fun on them, dropping the oil after each trackday seems to help.
