Infineon crash - AFM rd 2

[msdeeps]

Trying to fig out the crash, the corners workers told me there is a bump on turn 1, where you can see i had a moment on the bump b4 i crashed.

Was wondering if anyone experienced this bump before ? plz post any comments on the crash and how it could have been saved ?

owe. you ok?

Based on the video, it looks to me that you might have turned in too soon and touched the left-side curving. You were the one riding, so only you would know ... is it possible?

 

[msdeeps]

owe. you ok?

yeah, kinda ok now, but not fully recovered coz i been ridin frm the next day of the crash

Honestly never felt a bump entering turn 1. Wonder if you got on the brakes hard enough to lift the rear a little and when it came down that is the bump we saw?
Would also explain the extra speed that caused you to not be able to make the turn?

Just guessing here :teeth glad you were not to badly hurt. How much bike damage was there?

I usually dont take tht line, but on tht situation i turned in soon as a rider passed me from outside and i guess i hit tht bump, not sure if i hit the kerbing, nxt time i go to infineon i will walk d track and fig out these bumps, it might be helpful...

It's really hard to tell much from that video Sai - horrible camera angle for analysis.

 

[DonJigweed]

uh, it looks to me like he's well off the curbing on the inside, like at least 10 feet away from it. watch the video again, the curbing shows up on the far right side of the screen, not out the back of the bike or even from under his left foot. maybe that's the problem? you just missed the apex (curbing) badly and out that far there actually is a decent bump, one that many of us have never even felt before?

 

[Dove]

watch the video again

Don't tell me what to do. So, I watched the video again and yeah.

Sai - worst line ever, don't do that again.

Bad line and bad steering. OP's arms were straight as an arrow. OP, you need to drop your elbows and relax your arms. I can tell by the way your body got rocked around that you clearly had a bunch of weight on the handlebars. As soon as you hit that bump or whatever, the front end wobbled, then your stiff arms transferred it to the rest of the bike, causing it to get really unstable. If your arms were relaxed, I think the front would have wobbled a bit over the bump and then settled down and allowed you to make the turn.

I think we have a winner here. That is the way I saw it at least.

I'm not understanding how Rossi is entering a turn without weighting the bars with his newer leg out style on entry? I only ask because people always come back to not weighting the bars during corner entry or else but then we have Rossi obviously putting some sort of force on at least one of the bars.

Support yourself with your core/legs/tank. I think that's the goal?

I understand that but try going into a corner with the inside leg off all the way like Rossi and then get in to the corner without any weight on the bars, it just seems impossible to me at the speeds they or even we are traveling at in a braking zone.

Amazing what "aliens" can do :rofl

Weight on the bars under braking isn't the end of the world. To me, weighting the bars only becomes a problem when you're trying to steer, or riding over a bump/dip/pothole/crest of a hill.

I've noticed that the sooner I can relax my arms on entry, the sooner and tighter I can turn, BUT as my entry speeds increase I end up decelerating more or harder through corner entry thus making it more difficult to reduce bar pressure and turn the bike. :2cents

Edit: Good sample corner, turn 12 (at the end of the back straight) at Reno Fernley. There's a raised hump mid corner that runs across the entire track. If I anticipate the hump at all, I subconsciously stiffen up my arms. This upsets the bike and I run wide of my intended line 100% of the time. Same thing happens if I am still braking by that point of the turn. As soon as I relax my arms and just ride over the thing, my line stays exactly where I want it.

Walk the track with Dan Sewell before Round 6.

Yep, you turned in waaaay too early, and then I think you looked off-line, and when there.

Maybe the back stepped out on you, but I don't remember a bump in that turn. Nope, just cheked my on-bike videos, and I didn't see any bump THAT big.

Sai, from the looks of it you were totally off line. But once you ran off you probably could of rode that out quite easily? did you tap the front brake in the dirt? should of tried a little rear brake and tried to stay relaxed on the bars...

 

[RedMist]

It's important not to freak out when your going off and to use as much front as possible right up until you move into the dirt. I went off in one at Thill due to a false-neutral right at turn in and picked it up had my rear tire in the air and then right as my front tire was going to hit the dirt I just modulated the rear brake and rode it out easily.

I personally don't think you were that far off line though you were a bit. I think in the video it seems like your way off because you pick it up to run off but from the looks of it it seems that you wouldn't have missed the apex to bad if your little mishap wouldn't haven happened.

Just think real hard about what you exactly felt right before, during and after your bobble. If you really think about it and can remember you should get a good idea and with that video it shouldn't be that hard to jog your memory. I've taken turn one many different ways do to passing, practice or just simply missing my line for some undefendable reason and I've never come close to losing the front there.
