I know leather suits are good for sliding but what's the impact like?

Have you ever done this before? Improperly torqued steering head bearings can create the vagueness in the front-end you described. I had a few mid-corner "oh shit" moments after swapping GSXR forks onto my SV and this was why.

I'm also thinking this is the cause.

I am going to take a WAG (wild-assed guess) about the cause of the crash.

You said that in the transition from left to right the front end just "went away"; without more details it's just a guess, but bikes like the R1 (short wheelbase, little rake, short trail) can do a little "pogo" type thing where when you've popped from full lean to full lean side-to-side the suspension unweights for a second at the top of the transition.... a lot of it has to do with if you are trail braking or on throttle and in that photo, it appears that the direction of travel is slightly downhill which also contributes to the unweighting on the front.

Doesn't take much at racetrack speeds. Rushing even slightly downhill causes the vectors to change NOT in your favor.

Just guessing without more data. But I've lost the front in similar situations on bikes i was familiar with, on roads I "Knew".

This would be the runner up. Best to start with the more obvious causes.

Ranger, impacting anything at the speed I was going is gonna suck. But the collateral damage to me is minimal. The suits work best...if you don't slide into anything, lol. If I had just slid on the pavement and came to a stop, I woulda been able to walk away instead of crutching away in a lot of pain.

Chopper, my forks slide into the triple trees, there's no need to losen up the steering head nut.

The front end will act like a pogo stick under fast transistions because it is either not setup correctly or the valving is allowing too much rebound. This is one major issue on big pistion forks (which he doesn't have). It's possible that the rebound was too quick or compression a tad too tight. It makes the front wheel somewhat loose contact and allow slippage.

Right. I've felt that before. My transition was pretty much done and I was starting to lean the bike more. Could still play a factor after the fact because the suspension is trying to catch up, I dunno. It's just something I've never felt on the track or the street in my six years of riding. It took six years to have an official wreck. Not too bad...considering I ride like a maniac in most peoples' minds.

Ah, I see. I understand how it works now.

DLIT · 12-29-2010, 08:53 PM

The only reminder I'm keeping.

Mr Lefty · 12-29-2010, 09:36 PM

Damn D, glad you're alright...

that sentiment about not having fun unless you're going fast is why I gave up my RR... not that I was anywhere as fast as you or Trip... but the what if thoughts kept creeping in my head as I was riding... what if a deer... what if a car... what if gravel... ect...

I don't think dual sports are your thing... but there's a shit ton of fun to be had especially in your Local on them. and for the record I have 10x the fun on my DRZ being a hooligan under 65 that I did on my RR at 65+...

maybe get yourself a 'tard
