Interesting comparison between those two actually!
Can see that the fella riding definitely knows the track/takes better lines as he's much wider coming into corners, he really uses the full width of the track as well when exiting them which is good. You can also see where he's catching the other fella up entering the corers as well, looks like he's braking much later and harder than the chap on the R6. R6 does get better drive out of the corners though and then somewhat unsurpisingly obliterates him on the straights!
Damnit I need another sports bike in my life
At your age I would definitely be riding sports bikes. But just try to remember you're not invincible, cos it'll f**k you up for the rest of your life if you get it wrong on the road. They're designed to do one thing well - go bloody fast, all the time, and that's what you try to do on them. If you could afford one bike for track and one for road, you should definitely go that way, get the aggression out on the track.
But I'm enjoying my biking much more now than when I had sports bikes, so just remember, there's plenty of time to indulge in two wheel fun yet. Still yet to do a track day tho, so it's on my list, along with a good European tour - boxes yet to be ticked!
My next bike? Well, I think it'd have to be a Fazer thou gen 1!
