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.

Hopefully the occasional bit of knowledge slips in there!

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.

Simply superb, you have a gift of being able to explain obvious highly technical matters in laymans terms. Brilliant Dave, keep them coming love your workshop vlogs..

Great channel, really enjoy your videos 👍🏻🇬🇧

I like it Dave. And you doing 'Maths' wonder's never cease as every day's a day at school.

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.

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

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

If you get it bang on is that didley squat ?

splendid insight to the internal workings dave, cheers!

amazing content. I learned a lot. thank you !

Genius Dave! Brilliant explanation & remedy. Can’t wait for your spring time blast down your favourite bumpy roads full bore🚀

Tbh totally didnt understand but still loved the video Dave. As always a pleasure to watch.

Great work Dave, it also looks considerably better now ! Looking forward to the road test 🍻

Brilliant stuff

I get lost in the maths a bit (I left School a long time ago) but all the other info helps understand how this stuff works!! Great vid and many thanks for doing the stuff you do.

Asking a question for the Farm Bends crew and the Marshals International Liberation Front:- How many cream cakes were consumed in the lunch period whilst waiting for the air bubbles to perculate to the top? 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.

That was excellent. Very informative. The long explanation is most welcome 🤓. I'll look forward to the acid test 🏍️🌬️

Great stuff….

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.🤓

I think I need a beer now after all that math

A vote here for your cure for insomnia 👍

Great video and quality work as usual 😊

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.

Thank you Dave for another great episode I will be doing the same service to mine soon but I will be dealing with the Ohlins shock instead of the factory. Hope all is well and better weather ahead! Cheers from sunny SoCal!

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

5 ай бұрын

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

Seems to be a thing from that era with the soft spring / lots of preload . My gsxr 750 was the same at both ends .

Mine next please Wavey👍

Fantastic video Dave. Are the Ktec kits an improvement for road ring. I just bought an SP this past weekend. Looking forward to setting up sag and squat Cheers Jeff

I do like to work on my own bike but i dont think im going to try doing this 😆

still convinced the proximity of the exhaust to the shock in this design must be an issue with heat transfer

It certainly won't help, a little awkward to move the shock though 😂

I have a 2000 RC51 and I just recently picked up a 2006 CBR1000RR. How does the factory rear shock in the CBR compare? Is it also soft like the RC51?

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. Regards John
