I've gone from a NSR, to a GPz550, to a XJ900 and now a CB600fs Hornet. Have a little GP100 on the side too.
I like doing my own work on the bikes and have recently rebuilt the engine on the GP100 - initially a very daunting task but having done it I can't believe how bloody easy it was!
Only recently got the Hornet and it's great - so much smoother than my old 1980's XJ900...and though the tank range is a little annoying it's worth living with.
