I am working with a sample size of one but here is what I noticed when on a ride with someone who went dark side, and he was not on a rocket. He said motorcycle tires would shred in a couple of thousand miles so he went dark side. The small group of us went on about a 350 mile ride in all kinds of road types: heavy urban freeway, mountain sweepers, and tight twisties. The guy using the dark side tire was a nut (in a fun way, lol) who could ride the crap out of his bike, always toward the front, smoking that dark side tire, and just generally having a good time. But in the high speed sweepers or tight twisties he had to back off the throttle and would lag behind. When we got back to the straighter stuff he again would ride like bat guana. Again on anything other than a road with corners he did things with his bike I would not even attempt but in those turny spots he couldnt hang. Is this at all the norm for the dark side? I am not attempting to pursuade anyong either way on the dark side issue to each his own, just wanting to learn a bit.
