    The suspension of my bike was too soft - i got new stronger suspension front and now it's perfect for me. But the rear suspension is still too soft when I'm riding with my lady (as I usually am).



    Naturally she's too heavy because rear suspesion is almost acceptable when I'm alone - I am not a heavy-weight, only 100 kg (about 220 pounds), but she's so heavy 50 kg (about 110 pounds)...



    AND the new rear suspension should look like the original, chrome/steel... Any suggestions? How about suspension of CB 750? Or after 30 years should I just buy new originals?

    There are quite a few options that folks here have used, but the one that comes to mind is getting some from a Harley Sportster. The only real issue is keeping the eye to eye measurement in mind, though adapter plates can be done for minor offsets.

    Kawasaki ZRX shocks. The ZRX is a 500 # (227kg) bike they are longer 14.25" free length and the stronger springs plus you get remote reservoir and good adjustments.

    I have set on my CX500 but with springs matched to my weight (77Kg) they work very well. A couple other guys on this forum also use the ZRX shocks.

    Cheers, 50gary

    I am close to your weight, I am 230 lbs, and I run progressive suspension 12HD springs. I bought them off ebay. I have not had any issues with them, but I have not done any 2-up riding with them yet.

    I'm using air shocks from an '81 GL1100. I'm pushing 300# (close to your combined weight), and they ride very well.

    I was told that certain Hagon suspenders were what I want - stronger to last my wife's heavy 50 kg's (about 100-110 pounds). As I told I am not a heavy-weight, only 100 kg (about 220 pounds), but she's so heavy 50 kg (about 110 pounds)... that's why I needed stronger ones.



    And here is the result - see the lowest picture (or use Google Translator to translate the text):

    They really work well, it's almost like a German sports car now. No extra movements after any bump, not going too deep on any situation!
