16 stone = 101 kg (rounded down to nearest kilogram) which is >90kg. According to page 6.21 of the manual: Upto 90kg Front = 2.25 bar Rear = 2.50 bar 90kg - 183 kg ("Maximum load: 183kg" according to the same manual page of 6-21): Front = 2.25 bar Rear = 2.90 bar High-speed riding: Front 2.25 bar Rear 2.90 bar *Conversions into psi* There are two conversions that could be used: Page 8-5 of the manual uses 14.2234 - this has been derived from 1 technical atmosphere = 14.223 psi Common internet searches will reveal the second conversion: 1 bar = 14.504 psi Both will give results within 1 psi of each other: Up to 90kg: Front = 32-33 psi Rear = 36 psi 90kg - 183kg (maximum load): Front = 32-33 psi Rear = 41-42 psi Because the original poster's weight was >90kg (i.e 101kg) then, according to manual 2002.05-0.6x1, his tyres pressures should be: Front = 32-33 psi Rear = 41-42 psi Never have I seen 36psi for a front tyres, so I'm not sure where that's come from. Having said that, when I bought my 2005 FZS600 I found the front tyre to be 38 (and the rear to be 41) - so perhaps 36 is common practice despite the manual suggesting 32-33 ?
