Tyre pressures?

[pedalingfool]

Just a quick one really, I recently went from my trusty BMW k1200rs to a fireblade as I thought I prefered sports bikes. I found that with the standard tyre pressurs 32 front 42 rear it handles slightly worse than an Epileptic attending a 70's style ice skating party. :'( When I get home I find myslef worried that I'm not pushing the bike yet the tyres are starting to melt and I'm not even close to the edges of the tyre. can anyone suggest something! HELP,

Just thought I would mention it does alright over 80 mph but under that it just doesn't feel chuckable!!!

Alternatively 4 sale 2007 HRC fireblade, handles badly but good at wheelies. feels slidey and generally don't want to go where you point it!

42 psi in the rear seems a bit high, every sports bike I have owned has had about 36-38 in the rear. I run 33 front 36 rear in my TDM now, but then it is a TDM and not a Blade!!

You didn't say what year your blade was...unless you meant it was 2007

Anyway says 2.5 Bar front and 2.9 Bar rear.

1psi = 14.7psi atmospheric so...

Front = 36.75psi
Rear = 42.63psi

If the bike doesn't feel right, could well be down to the tyres you got on it?

I run 36psi front on mine and just over 40psi rear...any less than that I find the rear slumps and slides...and more than that and the rear end skips over everything.

You brought the bike from new or 2nd hand?

I got it brand new, and have a little under 5000 miles on it now, it's funny because it seemed to handle a lot better with a pillion on the back, it does handle very well to be honest just not as good as i thought it would be, on the whole a little disappointed with it!

drop the rear to about 38 if that does not work start looking at suspension set up as it has a huge affect on the way tyres work

[pedalingfool]

ok, I'll change my psi's to about 32 front 38 rear and see if I end up in a hedge, and get back. wish me luck this work lunch time!

been said before on this site but you could always take it to mhracing in corsham he will check your suspension settings for a small fee & advise on tyre pressures etc.
Mark is a nice guy to boot,set my bike up (even though it has useless forks)it has given me a lot more confidence turning in & winding on coming out of the corner.

I'll ditto that MHracing rebuilt my Ohlins did a top job and then tweeked my settings A********

Got the phone number? and I'll get it in and sorted!

As standard the pressures in the blade shoud be 36psi front 42psi rear...
But i would run 34psi front and 36psi rear to optimise tyre life and grip
