Hey Noggy. I might have missed it despite having read through all of the previous posts but is a Gen 1 in the equation ? Surely its an option ?
I personally think the Street Triple will be a bit cramped if you have long legs. You also mention you like to do 300 odd mile round trips and although most bikes will do this, there are obviously some that are better at it than others. I personally think bikes like the Street Triple, KTM, Tuono, MT09 etc would be a little tiresome over these distances but that's just my opinion as I haven't owned any of them but have considered them. I sat on a Tuono a couple of weeks back and the seat was like a plank. The same as with the MT09 and with the tank range of the MT09 you would have to fill up at least twice over 300 miles.
Have you considered (dare I say it) a Suzuki Bandit 1250 or a Triumph Tiger 1050 ? I'm thinking they are better for a taller rider, have plenty of grunt, are comfortable and could quite easily cover 300 mile stints. I'm also sure in the right hands they could be thrown around a fair bit too. Deceptively so in fact. The Tigers are still a bit expensive 2nd hand but the bandits are superb value for money. There is a 2011 model on Ebay at the minute with barely over 1000 miles on it for £4500 and it looks mint. They even made a limited edition streetfighter model of the 1250 with a single seat cowl, dual exit exhaust and Renthal bars as standard. Nothing groundbreaking I guess but they look pretty nice and the 1250 engine is allegedly a cracking engine with 80 ft lb of Torque delivered at around 3700 rpm.
They may not be what your looking for but if you go online and read the reviews, most of them are positive. I'll probably end up with something like that as although I can dream about a Ducati Hypermotard, MT09, Tuono V4R, KTM Superduke etc etc etc I don't really think they are mile munchers. I'm quite confident that they are stonking bikes but for me personally I imagine I would be wanting to go home after a 50 mile blast if my licence was still intact.
As a side note, Ogri's CB1300 looks awesome
