Looked to me that #62 had a perfect line and well ahead coming out of the corner...how #12 caught him was probably over reving before shifting as his wheel lifted when he shifted. You may be right though after a few more views, it does look like he is looking back and saying some unheard words of Take that you twit. No excuses though, bad sportsmanship and dangerous at best...and a nose wheelie was entirely possible had he held on a 1/2 second longer or hit it harder with those brakes, or possibly a high speed wobble crash (although those frames are pretty stiff and fork/rear suspension dialed in).

My 1050ST Turnip which was only 125hp, 500lb and change wet plus 240 for me, had front brakes like that and would toss you over the bars without judicious use...never did but, nose wheelied "Not" on purpose twice, when I first got it. And it only had dual 320mm 4 piston, fronts. My son's 1098S Duc was even more treacherous that way and it had 330mm 4 piston dual pad floating Brembo's but only 439lb wet and 160hp...a real Crate rocket. The old Z1 was a "Bruce Moose" comparatively to either of these...let alone what these guys are riding.
