Tyre Pressure
« on: 08 January 2017, 06:26:29 pm »
Hi guys


Just had a full service on my FZS600 and she is running perfectly, however tyres were a little flat, the garage bumped them up but I forgot to ask what they should be (Front and back)


I've heard it depends on the rider though so I thought I'd ask you lot what psi I should have in front and rear tyres


I'm 6 foot 2 and weigh 72kg (11.3 stone) (158lbs) What tyre pressure should I be riding on the front and back?


Hope you guys can help, thanks in advance :)

I'm about your weight and the bike is on BT021's (just 'cause I've always got on with them).


I run 36psi front and 42psi rear, but everybody seems a bit different.

They recommend something like 32/36 but if i ran the bike on those pressures the handling would be terrible, especially the front.


I'm over 16 stone and run 36/40, i used to go with 42 but found 40 to be just that little bit more suitable for me.

How do you find the handling because everyone seems to not go on the recommended psi because of handling issue's apparently

Common recommendation is 36/42, I was told many years ago run them a little lower so I run mine at 34/39, have done for years.

The handbook states 32 front / 36 rear.
Many people run 36 front / 42 rear.

To work it out properly, you will need to get your scales out as each tyre manufacturer gives different values based on the formulae below.

(Max pressure / Max load for tyre) x (weight on specific wheel in KG) = tyre pressure setting.

The Max pressure and Max load are stamped on the side of the tyre. The weight is you plus all your gear sat on the bike with that wheel on the bathroom scales.

Personally, I would go with 32/36 or 36/42 rather than fec about.

The handling is fine for my style of riding-I spent a bit sorting the suspension out last year. Replaced rear shock(Wilbers) & had front forks overhauled with new springs/oil/seals. The bike has been transformed. If I ws going 2-up touring I would up the rear to 40/42 psi.

That's just it though, everyone is a different size, carries more or less and rides their own way.
Ideally you should take a bit of time and try different pressures out, until you find what suits you best.
Remember though, in cold weather you'll tend to gradually lose air because of the cool temperature so it's never the same all the time anyway unless you check it weekly.

Similar = PR3's, 18 stone and running 36/42. Suits me.
Those are my principles...if you don't like them I have others.

Hi guys just wanted to say you've all been a massive help so far. I think because i'm a bit lighter than some of you (no offence intended) and I never carry pillions or much weight I'll stick to 32 and 36 for now.


Thanks again :)

Depends on tyres as well. Metzeler recommends pressure for their tyres per motorcycle model that (in FZS600 case) differs from Yamaha's user manual for the factory tyres.
Most things done in a hurry need to be done again - patiently.
