Tyre pressures

Due to lots of work over the past week (now almost at an end - thank god) i had neglected to check my tyre pressures. It has been about 8 weeks, and i finally thought i should check them. The FRONT was at 20psi, so just over half pressure. The rear, however, was just 13psi. Once i did this, i found i could corner again without having to throw myself into roundabouts. Infact, i nearly went off roading in the center of a few of them.

So yeah, dont be like me and neglect your pressures. If you havent done it in a while, go and do it now!

edit: for anyone's reference, correct pressures for the falco are usually as follows (be sure to check first though):
front:36psi
rear:42psi

2.5bar front
2.9bar rear

Check mine at least once a week. Should be checked every time ye go to use it, but that's far too anal for me..lol.

So how many rear wheels have you got on that Falco of yours? Have you done a BikerGran and Triked it?

I notice just a few psi reduction from the way it handles so it never gets far away from what it should be.

and last time I checked 20 was just UNDER half of 42

Maybe it's just me, but I generally prefer tyre pressures a little under the manufacturers recommendation. Although I do normally fit 'sporty' tyres which seem to suit a lower pressure.

34F 34R seems to be working well at the moment, apparently the Dunlop 'N-TEC' rear should be run in the low twenties on track!!

Most track tyres will run low to middle 20's (cold pressures) The tyre warmers bring the pressures up and then theyre maintained on track by the harder riding anyways.

yes, Tim.. you lower your pressures for track, dont you.. especially with brand new tyres or you wreck them in one trackday dont you....

I've always used 30F 29R cold pressures with Rennsports/Racetecs.

Dunlop give a hot pressure of 23psi for the D211GP rear!

Hot?! Ferkinell!

good write up on them : http://www.motorcycle-usa.com/545/100/M ... eview.aspx

that was meant to read 20 front and 13 rear. Silly me.

The 36/42psi is what Pirelli and most of the tyre manufacturers recommend.
Aprilia recommend slightly lower pressures (see your manual) - I tried them and, for me, the bike felt awful. Back to the Pirelli values and it was lovely again.

I always used to run 34/38 on my road tyres. Then a mate of mine told me to stick them up to 36/42 and try it out, I did and the ride was obviously a bit bumpier but the handling was much sweeter.

I assume you all have the same trouble as me getting to the front valve, but for those still struggling I would highly recommend getting a 90° adaptor, makes life so much easier.

Do any of you take into account your own weight (in riding gear) when setting your tyre pressures?

I ask because as a big lad (fat git) myself, its something I have to take into account and have done for a while.

This fact was brought home to me once again recently when I was discussing suspension settings with MangoCrazy. The combined weight of him and his missus was about a the same as me on my own!! so whats the point is setting to "solo" pressures and "pillion" pressures when it can be so far off dependant on the individual

I'm reliably informed that "most" solo tyre pressures are based "roughly" on a 12 stone rider

Worth thinking about I reckon

Admittedly, Mrs. Mango is tiny, but DAMN! You lardy git!!

I may have misheard, but I think Griff said the other day 32 front and 36 rear for a Falco, which seems a bit low to me. Will give it a go in a bit and see what it's like.

the one thing i disagree with griff about!

32/36 is what is in the falco owners handbook iirc

I ran my first set of conti road attacks on those and the tyres were poor untill warmed up - it was only when i was advised to go to 36/42 that i saw an incredible change

I would use that setting as a base line then go from there
