    New rear springs for my CBX

    So my CBX seems to be undersprung for my petite 105kgs. Its a twin shocker, can I get up rated springs?

    Not easy at all for oem shock springs, nigh to impossible without making adaptation spacers. But also the shocks are all but single acting, there is little to no low speed compression damping, that is a about 50% of the contribution to it riding too low in its stroke

    So I cant get a spring maker to wind some up? Need to work out the rate of mine as they seem to be progressive.

    If you can find a springmaker in NZ that uses spring stele that doesnt sack out, yes. Unless that unsatisfactory situation no longer prevails it will end in tears. This though is still a bandaid as the spring rate issue is only 50% of the problem

    I wasnt eluding to your personal stats and your reply surprises me as I was stating the situation with the suspension. Apologies to be so candid.

    I was taking the piss. lol. No worries. I should eat less pies.

    I will probably just leave it as it is. More i think about it the harder it gets. Its a 1k bike that I will have for a year. Not worth the money to be spent on it.

    I know one....but they can't wind stuff that small in diameter.
    Maybe the shocks off a cb1100 or something will fit?

    Keep in mind that whatever you spend on it wont increase the value.

    If your not keeping it long I wouldn't worry about it,I scootered around 4 over 2 years with the standard rear suspension on my rs and I'm 20kg heavier than you.....

    But FYI the rear shocks of a GS550 should fit...well they have on my Cb250rs frame I just had too swap the top rubber gromet over was all

    Whats the spring rate, base preload, damping force and motion ratio comparison?

    I will just drop the oil out of mine and throw in some 30/40. Worked in old Toranas back in the day.
