A local outing

Race track...? 
Did 2 track days on that on 2 different GSX-R750s. The older, slightly heavier SRAD was solid as a rock all the way round, the newer, lighter one scared the shite out of me down the Craner Curves, back-end wagging like a Portsmouth Prostitute. A £30,000 fully race specced CBR1000R lobbed it in front of me on the first session there...I think that may have dented my confidence somewhat as I had to ride the GSX-R back to Surrey that evening...my mates all had their bikes in vans or on trailers.
track day on a bike 
Loads. Favourite, Brands Hatch GP and Indy, worst Rockingham and Cadwell Park (the mountain scared the bejeesus out of me every time). I was always perhaps a bit of a scaredy-cat a I just turned up took the wing mirrors and number plate off and voila. Knowing I had to ride it home later that do...so possibly a bit cautious. Also didn't want to get hurt
Mates did too at first, but eventually started bringing dedicated track bikes, but they were mainly CBR600s and I could demolish them even on a stock GSX-R750. One eventually bought a Yamaha TZ250 ex GP bike but his best on Brands Indy was 54.1 seconds and mine was 52.8. That's the problem with exotic stuff like that - if it wasn't jetted exactly correctly for the temp/humidity etc. it did perform to its potential. Didn't stop me taking the piss for months after mind...
It cost him £12,500 but being so rare, he sold it 5 years later for £18,500 so he had the last laugh.
