Came off at Cadwell Last Week
Discussion
Hello Everyone,
I low sided on the exit of Barn on Monday last week. I was lining up an undertake on to the start finish straight and tipped her in a little more and started to apply the power which lighten the front. Front washed out and I was on the deck. The first thing I remember is is seeing the bike sliding down the circuit and my arse heating up from the friction between my leathers and the tarmac. Turns out I was running my tyre pressures too high and that combined with the fact that Barn is off camber.....
The bike slid on to the grass where the crash bungs dug in and flipped it in to the tyre wall. Damage: Big scratch in tank. Tyre marks on tank, front fairing and screen. Top fairing broken beyond repair. Dash broke off. Bungs on right hand side of bike worn away. Left top bung snapped off. Mirror supports bent and central air duct smashed at head stock. Clutch lever broke and bent up. Considering the speed and hitting the tyre wall the bike came off pretty well. All parts are being replaced this week as I'm doing a track day at Folembray on Friday
I was wearing Wolf one piece Kangaroo leathers which held up quite well. Don't know what speed I would have been doing but I did slide quite a way before going on to the grass. A hole was worn through the leathers with the second layer of leather holding well. They are being patched at the moment but will consider a more robust set in the furture as these really seem to be only one crash leathers.
LESSON: make sure you're running correct pressure and take it easy putting the power down on off camber corners!!!
Some photos I'm riding the Black Aprilia Factory with Silver number boards on the front.
Cheers

Slightly concerning that you're leathers worn through as barn has to be one of the slowest corners at Cadwell.
Always a bit dodgy round that area. a) its under the trees & always seems a bit greasy, and b) the camber at barn is not in your favour.
Should have been there today but woke up at 5am this morning & it was teaming it down. Couldn't be arsed today with the hassle of a wet day. Waste of money but .........

Me neither. How I hate throwing money away........but on the plus side, I won't have any bike repairs to carry out at the weekend!Always a bit dodgy round that area. a) its under the trees & always seems a bit greasy, and b) the camber at barn is not in your favour.

Nice photo's mate. As we've said, could have been a lot worse.
Any news on those parts?
My Pazzo levers showed up this morning Any news on those parts?
Great pieces of engineering. Just needed an excuse to buy them.Hopefully the airduct and mirror stays will show up today.
How where the Stomp Grips this morning?
I was running what I normally run on the road as I don't view myself that fast to warrent lowering the pressures. I had Diablo previously which I ran at 34 and 39 bar on the road.
I was running Pilot Power 2CT's at the same pressures as my Diablo's when for the road they should be 32 and 36 PSI. For the track I've been told to run them at 30 and 28 psi. Yes they said to run the rear at a lower pressure than the front. They being a source from Michelin I cannot 'quote'.
What is everyone elses thoughts?

Tyre pressures are a bit of a black art - I run 34 (rear) 32 (front) on the road and 32 (rear) 30 (front) on the track. I've crashed on both the road and track so don't copy me! Seriously tho, the bike handles well so I've stayed with these pressures. The track pressures definitely worked for me - last time out on the track, the tyre looked used but not totally melted as they normally do.
I have Diablo Corsa III's on at the moment.
Edit to say your pressures were too high - even a slow rider will generate much more tyre heat on the track.

John Laverick]I run my 2004 R6 on Continental Attacks at manufacturers recommended pressures [36 front and 42 rear said:
. Got my first track day at Cadwell in a couple of weeks.
Should I be thinking about adjusting tyre pressures?
Yeah, 100% you need to be changing them. Ask at the track and they'll sort you out - something like 32 rear, 30 front should see you OK. Hobo rides on track quite a bit so maybe take some advice there...Should I be thinking about adjusting tyre pressures?
John Laverick said:
Thanks guys.
Are they the correct pressures for the road then?
They're the same recommended pressures as my GSXR 1000 so are fine for touring style riding. If you generate some heat and start hard road riding then you'd want to change them again. When the pressures are high (as per recommended pressures) the tyre lasts longer but it doesn't allow much of a contact patch. When they're lower, the tyre deforms more allowing for more tyre on the road. If they're too low, the tyre will deform too much and again change the way your bike handles in a negative way. That's why it's a black art - different for every rider and his / her style. Are they the correct pressures for the road then?

Although the only riding I do is fast road [no touring etc...] so maybe I should drop both a little!
Thanks

No.Are they the correct pressures for the road then?
Track days pressures are different due to road due to the differing conditions. On track you'll heat your tyres up much quicker than on the road due to the maintained higher speeds & harder braking.
Don't ride your bike on the road on track pressures !!!
