But...I think I have more fun on the small bikes. I don't like having to worry about spinning the rear tire.
Spinning the...what? I'm still laughing. Dude, no spinning of rear tires is happening in vintage 350gp. Some 350 or 500 guys on this forum might beg to differ, in which case you can decide who has more credibility.
"Spinning" is sort of a loaded word, which we can get into if neccessary, but I don't think it is. The point is I don't think there's really any difference in handling characteristics between a fast 200 bike and a 350. You can smear the rear tire with cornering force and too much throttle, but it doesn't really "spin".
Yea, there's more power with a bigger bike, but not so much that you'll hurt yourself. Even if you had zero throttle control it would be hard to highside a 350, and I know you have some finesse with your right hand 'cause Aaron told me. Seriously, you can't ride a slow bike on the track as fast as you and be totally meat-fisted.
Speaking of baselines Johnny, here's one for you. In 5 seasons of racing modern 125s, I've highsided three times. Once as a rookie in the wet. Once exiting 12 onto the straightaway, which is extreme lean. And Once as an expert in the wet, trying to catch a guy on a Duc 1000 DS. To me, highsiding a two-stroke in the wet is pretty easy and plus I was really pushing the second time it happened. ANYway, a 125 is much less forgiving and much more powerful bike than a vintage 350, and even then you don't highside much.
ps - i really want to try a 200. i'm accustomed to small bikes too, for the same feminine reasons.
