If the rider stays in it as the bike goes down, the rear never regains traction, right? But if the rider chops the throttle, the rear might hook up and there's your highside.

Flat trackers do this intentionally. The rear tire is spinning like crazy, the bike is sideways, but the front is still hooked up. Easy to see how going too far with that could lead to a low side.

(google, google...) Ah, here it is in action. Rider is spinning the rear here, classic flat-track style.

thanks, that's really helpful info. I guess I never seem to get back-end around with power. Back tyre just grips, speeds up bike and tucks front-end. I guess that's what i get for running stock front tyre size while increasing rear two sizes up.

I'll try bringing it into better balance with stickier compound in front, or maybe even a 120/70 front.
