Don't listen to him. You may have crashed because of a combination of too much input (brake or gas) and too little traction (which decreases with lean angle) but you certainly didn't "roll over the edge." Even on street rubber, which does have a milder profile than race rubber, you'd have to near drag bodywork to accomplish this.

Great info guys. I wasn't going to jump into slicks just wanted some info on them. The edge of my tires had "blued" from prior track days. Don't know if that had anything to do with it. I'll listen to what footage I have tonight, and see if the bump caused me to abruptly close the throttle and cause my low side. Or, maybe I did lose grip. I would like to know what caused it do I can avoid this situation again.

Race tires generally have a steeper profile edge, which maintains a good contact area at higher lean angles.

I run 180 s20's on my street bike, which i ride fairly conservatively and have no chicken strip left. They have about a 55 degree edge.

In contrast to my 190 r10's on my track bike, which i try to get down as far as i can, i still have about a 1/4" untouched strip. These have about a 65 deg edge.

Even though I'm not using all of the tire or lean available to me, that extra safety margin of that 1/4" that the r10 gives me is worth the additional cost.

Don't skimp on tires.

The bump is about 75% through the turn, and significantly off (wide of) the line, The line is sucked up against the curb. Allllll the way around.

probably. I checked the video. my mounting indeed was pointed towards my throttle hand. I was not on the brake and throttle was constant. Can't really tell but I was halfway through the turn it seemed and then I started surfing. Will trim the vid and post it up to see if someone sees anything.

owwwww! I lowsided a xr100 and lost. You are lucky to be walking my friend. Im still looking at 2-4 weeks of a walking boot that I am not yet walking in plus weeks of physical therapy just to walk in a shoe.

Looks to me like you just leaned that over too far and traction said bye bye.

Looks like you started turning the handlebars into the turn instead of countersteering.. but can't tell if that was before or after losing traction

Blanco, how you holding up man?

Im holding but sucks major ! Too much time without mobility. I created the perfect storm of injury:

Broken Fibula
Dislocated Ankle= 6 weeks to begin thinking about walking

Add Torn Deltoid ligament plus surgery to repair= 2 more weeks to equation above plus untold weeks of physical therapy just to walk normally

I will overcome this but it aint easy. The hardest pill to swallow is that a mini bike wreaked havoc on my at 5mph!

.. I saw your x-ray thread and cringed. Didn't even want to see the surgery pics. lol

Based on the happening to ppl on the small bikes, I think I'm going to stay away. 600's for life!

Hope you heal soon man.

Nah. Watch any racer lowside: the front tire flipping the other direction is the first indication that the front has lost traction.

Not saying that's what happened to Tran, but that was my first thought
