I tend to go with what the manual says or the tyre if it's higher. Currently at slightly under 95 kg and still dropping the kilos! Tyres on Jack (2007 CBF250F): 33 front and rear. Manual recommends 36 on the rear with a pillion. Tyres on Nix ('98 ZZ-R250): Lower than they should be because I haven't spent long enough at a servo on her yet and my foot pump is cheap and nasty - manual says 28 front and 32 rear. Tyres on Rosie (2004 KLR650): Manual suggests 21 front and rear if under 97.5 kg load, 28 on the rear if load is 97.5 - 185 kg. Tyres on Bruiser, Eric & Scarlet aka "The Triplets" ('80, '82 and '83 model CB250RS): Not actually checked the tyre pressures yet but the manual recommends 24 front and 32 rear, 36 rear with a passenger. Sheesh, I have a lot of bikes these days!
32 front and 36 rear on a cb250 lugging a svelte 125kg or so rider. Yes, try to picture that and not feel for the bike.
Went 35/38 this morning ..... maybe slightly too hard ...bike rode fine but a bit solid on the bumps ...... of course the crappy FZR suspension could be blamed for that
Hey Grey Perhaps a tad high at both ends, you must remember the suspension isn't new anymore and with added pressure in your tyres, suspension doesn't cope as well as it once did. Would be a good exercise as you ride to lower the pressure a little at a time until you find the medium that best suits. Hey, got nothing to loose.
I'm running 29 Front 30 Rear Hot on the Track Fizzer. Cold they're at 24F and 25R. Running Dunlop Alpha 13's. Looking for a 4-5psi increase from cold to hot. Only take note of this for track riding as the pressures are way too low for the street and you wouldn't push them hard enough to get them up to temp. It is interesting reading how high some of you are running your tyres cold even on the street. I'd stick to what the manufacture recommends for the street (generally 32psi cold) then experiment from there. Too much pressure and your tyre won't heat & won't flex, too little and it will overheat and have too much flex.
I have been running 24F and 28R for the track. Seems to be pretty responsive. Having trouble keeping the heat in them in the cold weather of late. Will go for some warmers to save losing track time warming up the tyres.
