    Surly I can’t be the only one that has no clue how suspension works. I could literally watch this video one hundred times, and take notes. And I’m fairly sure I’d be none the wiser, probably just more confused. It’s still nice to watch someone who does know what they are doing. I always enjoy the content and the way you deliver it Dave. Can wait to you actually get to ride it.

    This man understands suspension. I know that when it works well a bike feels lovely, and when its doesn't the bike feels out of control and uncomfortable. knowledge is power! Thanks for the video.

    Wow, what a masterclass on rear shocks!!! That was amazing. Thanks for sharing all of that.

  • @bikerjock2654

    Brilliant! Watching a master at work. I understood all the words you were saying, while you were saying them, and it made sense. But, the instant the video ended, I was left with a pile of random words - except maybe the pro/anti squat bit, which still makes sense. I wonder how that applies to a shaft drive (my R1200S) - I suspect it works differently in how it affects squat... …or not?
    When I first bought my R1200S 12 years ago, at low speed, it felt like it had wooden tyres, and no amount of adjusting eased the problem. I eventually rode it to Birmingham and left it with a suspension expert. He found that the shaft in the rear unit had a tiny blemish, which had worn a grove in an internal seal or bush (I can’t remember which), and that was preventing the shock operating correctly at low speed. Oddly, I would have bet money on it being the front shock - I was getting most of the uncomfortable wooden tyre sensation through the bars.

      @obsession_engineering  10 หลายเดือนก่อน

      Now that is interesting, a bit like a too tight chain not allowing the swingarm to move correctly.
      I've never played with shaft drives much so would have needed to do my research

    Dave I love everything you do and your crystal clear explanations. Might it be worth getting a tripod and including a bit more of the hands on stuff so we can see a few more of the actual maintenance tasks as well as just hearing about them? I'd love to have seen the spring on the lathe for example.

    Fantastic explanation of all concepts there. Followed all the logic and feel much more informed about rear suspension now. Will now spend a bit of time considering how to apply this new insight into my own bike and situation. Ah! Slight problem. I ate ALL the pies and they don't make a spring rated high enough to handle my sag. 🤔🤣In reality I now have a good sense of what I need to acheive with my adjustments to improve the very issue you discussed here, so thank you very much for this upload. Each time I get it a little bit more sorted in my head.🤓

    After refurbishing my rear shock, I also shimmed it when I refitted it, just 5mm, but it was still noticeably better in the bends. I've seen people do it 10-15mm before on ZX9r's, not sure if it is necessary to do it that much.

    • @obsession_engineering
      @obsession_engineering  10 หลายเดือนก่อน +1

      My zxr750 needs lots of ride height, so quite likely the zx9 is similar. Probably a bit excessive with the antisquat, but necessary for the centre of gravity

This is the most important part of the set up, the increase in your body mass. See you at the Mount. ;0) From Angela and Pete and of course the rest of Orange misfits.

    Just got my rear shock back from a full service plating and stiffer spring.
    I fitted 6mm spacer at the top of the shock also.
    What height would you recommend the forks go in at ?
    What tyre pressure would you suggest?
    Fingers crossed it rides better.
