Tyre Pressure on Aftermarket wheels?

[joebloggs]

I *think* the previous owner of my Fazer has fitted aftermarket (possibly R1?) wheels, and fatter tyres than the stock ones.


Whilst this makes handling lovely, and long sweeping bends an absolute pleasure (though it does give me the turning circle of a battleship)... Ive got no idea what pressure I should set my tyres to! Any suggestions?


I think tyre sizes are front: 120/70/17 and rear 190/50/17 (though doing that from memory, at work at the moment! Will have to double check when on break! )

The pressure they would have been set at on the R1
