    Benelli BN 125 Tire Pressures

    I’m a new rider, I’ve looked through my bikes manual and there are a few bits that mention tire pressure, but it’s not clear to me, so I’m a bit unsure what pressures my tires have to be....I’ve always measured pressures in vehicles as PSI, but the manual doesn’t. One page has Front 190 kph(1.0kgf/cm2) Rear 210 kph(2.1kgf/cm2).

    Then another page has: Front: 100/80-17 (52P 52S), Rear: 130/80-17 (62P 62S)...now I know the first bit is the tire/rim size, but what are the “P” and “S” figures?...is the P for PSI?...Can somebody clear this up for me?..😊

    Looking at your info here ..
    The Front tyre works out to be 1.9bar (28psi roughly) and rear tyre 2.1 bar (31psi roughly) .
    52 and 62 are load index relating to max weight Google a chart .
    And th p and s are related to the max speed rating again on a tyre index .

    Hope this helps

    Pump 'em up until they burst, then back the pressure off a bit.
