A Street Triple with sorted suspension is VERY VERY fast in bends. You can pretty much do what you like - it has no torque so losing traction is hard. But revs so has some power.
I have to be honest - I am starting to miss this aspect of biking - I always had one 500cc bike in the stable when I was younger. Esp Laverda Montjuics. They were just "fun".
If I could get it legalised for use in Spain - I'd buy one tomorrow.
This category of bike is pretty much what feeds dealers here. Sub 1000cc are cheaper to tax by half - literally. And insurance MUCH lower.
Most road tyres are not really that safe past 38º (according to the tyre reps I've talked to) and most "cruiser" tyres about 33-34º. If you go to Super-sport then OK and race tyres are obviously different.
