Help Needed.....

Just pulled my 02 rsvr out from winter and checked the pressures and the front was showing 34 & rear bloody 16..... I looked on the net and the pressure for my Mich power pure
180/55-17 was 40
120/70-17 was 36
Inflated them to this but it feels pretty crap to be honest not feeling that gud when getting chucked into corners feels a bit wobbly??? Has anyone got any ideas what i should set them to as i came to work on her today and the sun is shining so i,m looking forward to giving her some rubber burning on my way home.

Thanks in advance

Found when I used Michelin's I had to run them with fairly high pressures to stop them feeling squirmish when cornering .. Ended up run 40-42 cold rear & 38-40 cold front ..
 
That's some serious pressure you guys run your hoops on! When they get hot they must be like concrete??
It's all personal I guess but I run them at the pressures recommended and they stick like glue. If I have them firmer the rear spins and the front feels vague.
32-33 front 36 rear (190 section)
 
Never had any grip trouble they performed excellently , but I don't tolerate the wall flex that Michelin tyres display
 
the manual is not the best reference.
WHY?
your bike may now be several years old mines an 02 R
think how tyre technology has changed in that time.
use the tyre manufacturers reccomended pressures as a starting point
most of them are now reccomending 40+ in the rear
and adjust until your bike feels right for you and the way you ride
 
I agree the manual is not an absolute. For an older bike, I would use it as a starting point. Mine is not old enough to worry about.
 
manufacturers recommend high pressures in the back as they take into account average road riding with you maybe taking a pillion.

And pressures will change with ambient and road temperature, so a manual is a guide for average Joe. Nothing wrong with going with what works for you.

This is what i think be it right or wrong. ;)
 
It's def all personal preference. But softer tyre=larger contact patch, more deformation and heat and subsequently grip. Firmer tyre=smaller contact patch, less heat build up, slightly less grip but possibly a sharper ride.
My personal opinion for what it's worth is that the old stance of 36f 42r is way too firm for hard riding and if nothing else transmits alot of road vibration through the bars
 
God no, guys!!!. 42 rear??!!!. :eek:

Pilot Powers work to their best at 34 F / 36 R. Forget the Aprilia manual when it comes to tyre pressures. Go with the tyre manufacturers pressures, each type of tyre can vary to a certain extent as far as pressures go but most are in the same ball park. The tyre manufacturers know their product best and test them for thousands of miles during the products development, this is where the pressure values come from upon release to the customers.

There was a thread about this over on AF1 a while back and within, there was a link to documentation from Michelin who recommend 34/36 for the Pilot Powers and 2CT's. I have always ran my 2CT's at 34/36 and this provides vastly improved handling over 36F / 42R which is quite frankly, horrible to ride on. :thumbup
 
many tyre manufacturers are recommending 42psi for the rear, i agree with you this is horrible i had a pair of Pirreli Angels fitted which felt rock hard upon checking the pressure i thought the tyre fitter had overinflated them with the rear at 42psi but this is what's recommended

36/38 was much better:thumbup
