Most tyre manufacturers recommend higher tyre pressures than Buell tell you to use with the standard Dunlops.
36/42 seems to be what many of them tell you to put in their tyres, although I find these a tad hard.
I use 35/40 meself, but I probably weigh twice as much as you do.

Have you got the front end off a GSX fitted to your bike? probably completly the wrong spring rate and they may even be the wrong length, try a buell one. :idea:

Is that 35 front and 40 rear old chap? 8-)

They're actually quite similar to the Buell item, and the issue was there before I changed the frontend. I think I literally just need to increase the tyre pressures to create a bigger 'crown' of the tyre (not sure how to describe this in writing) so that it tips into corners easier.... Its getting there now. I'm already feeling more confident on the bike. :yup:

Indeed it is.

What do Bridgestone reckon you should use in their tyres?
Try searching their site.

Common, 30Psi isn't exactly running it flat, is it now? I prefer to run it a little softer to increase the grip levels of the tyre, but while that works, it does appear to have the side effect of making the tipping slower.... :sad1:



Tis more than 25% below the recomended pressure though ;)

There y'go, Mich, Bridgestone's recommended pressures fo an X1:

http://www.bridgestonebikersclub.co.uk/guide/

If you need to convert bar pressure to good ol' PSI:

Wonderful thing, the internet.

My point exactly, 36/42 psi have been the default recommendations from all tyre manufacturers for quite a few years now. To my knowledge all tyre manufacturers recommendations are, where bike manufacturers (presumably rightly for their specific bike) suggest otherwise, is to use their recommendation or the manufacturer's maximum recommended pressure if lower. Not having 'a go' at you at all Mich, just that anyone going out without checking their pressures, let alone questioning their bike's handling, is likely to be swimming with piranhas in the morning, whether or not they have lived near the aforesaid river or not. :P

Kev's voice of reason and % evaluation is band on, IMHO.

Stay lucky.

Running your rear on slightly lower pressure only works if your gonna be gunning it and keeping the tyre hot, or its a hot sunny day.
The increased temp of tyre increases the pressure to near the manufacturers recomendations.
Conversely running your rear at 42 psi on a hot day and ragging it will cause the pressure to be higher and the tyre will skip and step and make your suspension work really hard.
Get a portable pressure guage and test it on a run you'll be amazed at the differences in readings you get :idea: :yup:

The beauty of this forum is that you get an opinion whether you like the answer or not :)

Maz's happens to be a very qualified and experienced one ;)

which is why you set your tyres pressures when cold. you don't set them lower.

In general, (not aimed at you Mich in particular) I wonder why riders set their tyre pressures to what they think is best, based on thier own theories of grip, handling etc.

The manufacturers have spent years and millions in testing these tyres to give us the pressures best to use based on years of tried, tested and qualified methods .... why then would you use anything else unless you are racing on the track or have a very particular riding style :?

Because we can, I'd guess.
It's just another human trait ;)
