i ride me a mini ST bike (Yami FZ-6 with bags'n'shit) and my old man's got an R1150r and honestly 90% of my rides are over 50 miles at a time. Ive done a few 500+ days and many over 200, and the bike is fully capable. Then i unclip the begs, and slay the twisties. Out distance the cruisers, and dust the sqwids on the "slow, uncomfortable" 600.
i had a guy on a gixxer 750 trying to get away from me, and when i caught up to him at a gas station, he thought i was his buddy on an R1
he was kinda upset about it actually. if i wasnt just in jeans i woulda got that knee down and really spooked'em.
i dont really think that STs are super rare because most of the guys I ride with have them.
