What tyre pressures to people run on Diablos?? 34/36 like the manual says?

Works ok for me... I give em a check up every couple of weeks too, to make sure they are still at the correct pressure....

Does yours flop into corners at low speed?

Sounds like you need a little more support

What pressures do people run on track?

I am wondering if it is me and the Diablos not getting on.

May swap wheels between Firebolt and 1125 at the weekend...

Seriously though Plash, I presume these are new tyres and the last ones you road on were they partly or more worn?
I always feel with a rounder profile new tyre that the bike at low speed easily rolls , once tyre starts to wear and the profile changes this slows down.
It can be quite noticable till you get acustomed to it.
Just a thought.

And a very noble thought too

I don't honestly know my tyre pressures, I have a quick look at them each time I use it and give them a kick no and then! I have no problem with "flopping" at low speed and I have the standard issue Buell owners physique!

How many miles have you got on the bike now Pash ?

You may want to have a little play with the suspension setings to see if you can dial it out if it doesn't go away once the tyres are bedded in.

I have to admit my bike feels a little "loose" going into a corner if I'm going down hill - but I've got used to it and I don't want to mess with it as it is fine on the flat.

Also need to change tyres soon - I'm considering the Pirelli SuperCorsa BSB tyres - but I'm trying to find out more about their wet weather performance as the tread is a little "conservative", but I reckon they'll be wicked in the dry ...

As to tyre pressures I stick to what Buell recommend - but I have to admit that I don't check them very often.

Do yours "white line" when filtering through traffic?

The flopping into corners may be a bit of a poor description, however I find, on small, slow speed (up to 30mph) roundabouts, I have to push back on the bars to keep the bike from turning tighter.

My Firebolt doesn't have this problem (it handles perfectly ), nor does my S1 (but then again, that is a wild stallion )... They both have Dunlop Qualifiers on...

Pash - tried Corsa III on the firebolt a couple of years ago and thought the Daiblo T were better all round, so when I bought the 1125 I took the wheels off at about 650 miles and changed the tyres, I has experimented with tyres pressures with Corsa III and found that for my riding style 33/35 seemed better than 34/36 and beilef me you can tell the difference in one psi under.
I had been running on Metzelers which i also had fitted used on the Firebolt but have just fitted the Diablo super corsa CS1 front SC2 rear to the 1125R which I had been saving for the track.
If you swap wheels between the Firebolt and 1125 then I am sure you remember that the rear tyre will need reversing on the wheel.

PM me if you want any further words

Pash

Put some more air in the tyres, especially the white lining is a symptom on my bike of being a few psi under par.

Don't go on Buell handbook pressures ...go on the tyre manufacturers

Across the board tyre pressures are 36 psi front and 42 rear, I personally find these too high, but that's what the manufacturers have agreed on....
