Time to rebuild

Simply put, I ran out of the minimal talent I had at the Ridge on Sunday and had myself a decent crash! My gear did its job, so all I have is a bruised palm and some sore shoulders. My bike....well, it's not as bad as I've seen, but it did take a bit of a beating:



My first question would be, does anyone have any tips when it comes to bending an aluminum subframe back into shape? It's a Motoholders subframe that is on there and the plan is to try to bend it back into shape before running out and buying a new one. I'd say it's 3-4" off center. Should I bend it while it's on the bike, off the bike or a little of both?

Also, there's lots of track fairings out there, but which ones hold up the best? The one that came with the bike seemed pretty cheap, as it was nearly impossible to get the right mounting post to stay in its hole because the structure that held it collapsed whenever I tried to push it into its hole on the frame. Also, would it be crazy to Line-X (not the spray can stuff) it to add more rigidity/resilience to the fairing itself? I don't think added weight is an issue, since I could lose 30lbs myself. I've always been tempted to do it and I can't see any real negatives, but my track fairings were fine before this weekend and I'd never do it on a street bike.

Ah, if only I had a video to share with you all! The crash was very similar to one I saw on PNW Riders years ago (B-King going off at T1 at high speed). It was definitely a learning experience and actually not as scary as I thought it would be. The folks over at the MX track got a great show!! In the end, at least I wasn't the guy with the new Honda SP2 that crashed. I'm SO glad I invested in a track bike last year.

I have had success bending a couple of subframes, ZX-10, R1. You can do it mounted so the bolt points act as a jig, or build a simple jig on a bench. Used a rosebud and learned to be very careful as it seems the bending point versus melting point is very easy to cross. But it cools off real quick too...

So I shouldn't just stick a 2x4 into the subframe and just start bending?! Oh man, I'm glad I asked. I don't know why my brain skipped over adding some heat to do the job.

That SP was sad to look at..
Which session/group did you go down in?

I remember seeing the B-King incident on PNW.
Any thoughts on why the crash happened?
Maybe some faster folks running in hot on the inside of turn 1, took away your apex?

Never mind, I see the missing front master cylinder and that verifies to me which bike it was. I had the front row seat for that one. You came past me (baby blue SV) and my student on the left approaching the turn in point to turn one, this set you up to having your bike not pointed proper for the apex which pushed you wide. It appeared as if you panicked/fixated at that point which pushed you further to the outside of the turn. From corner entry, you came back across me left to right and just kept drifting wider. I was literally looking over at you saying to myself "eyes to the inside! trust your bike! whatever you do, don't grab a...handful.....of......the........." then I see the puff of white smoke come off your front tire and there you were sliding down the pavement next to me. So glad you were OK and the bike didn't look too bad. Funny thing was when I slowed and pulled off the track to assist I hit some of that deep pea gravel shit almost at a stop and dropped my bike as well...

Oh man, I'm glad I found you!! Thank you for the break-down of the crash. It all happened so fast that I wasn't sure if I remembered what happened correctly. It happened exactly like you said; I came into the turn incorrectly, target fixated on the edge of the track and I screamed at myself to look left a split second before I went down to try to correct but I failed. I thought I let off the brakes and caused my front end to lift, but if you saw a puff of smoke then I didn't lift! Obviously you don't mind because of the laughing emoji, but I'm sorry that my off resulted in your bike going down while you stopped to help. Honestly, your bike going over and me probably scaring the shit out of your student are the two things that I've been the most upset about since it happened. As for me, I'm A-OK and the bike is probably a $500 fix (if I can bend the subframe back into shape).

Man, this response has made my day....thank you!!

No worries, the student really wasn't spooked and it offered a unique learning opportunity, one of two that happened in front of us that day. The other one in turn 8. As for the bike, it's a track bike. No notable damage of any kind.

Well, thanks to your details I'm now able to fully understand what happened and hopefully I won't make the same mistake again. Hell of an experience though, but it's kinda nice to finally have my first crash out of the way, so that it won't be lingering in my mind anymore.

Now I send the photos of my bent up subframe to Wasco to get a quote! I'm also thinking Sharkskinz as my replacement fairings. The belly pan and tail aren't in too bad of shape (nothing a little epoxy can't fix), so I think all I need is a new upper!

Thanks to both of you for the dialog. This helps new track people like me in the short/long run.

I wish you both safe tracking in the future.

I'm happy to share! The more of us that can learn from my mistake the better.

Richard at WASCO is just down the road from you. Does great work.
Also take a look at Flexi Glass, somewhat local (BC) company, good bodywork, great guy.

If taking it to WASCO, don't try to bend it back into shape yourself first. It just makes his task that much more difficult. He will want it in as-is condition.

Wasco got back to me very quickly with a quote and considering my non existent bending skills, I'm just going to take it down to them to get it all fixed up. Again, I'm glad I asked the forum for options before I started mucking with things myself!
