I like seeing how Dave makes compromises on bikes that don't have ideal adjustments available. This was the story on my FZ09 (as has been documented by Dave). Thanks Dave!
Thank you for your knowledge sharing Dave and hope you are feeling better. Recently softened rebound in rear shock from factory default for 1 up rider and it made a huge change to stability of my BMW F900XR in corners and comfort on the street. Thank you!!
At @10:09 - I dont understand Dave's statement regarding the forks behaving independently due to different preload setting. I thought that once the axle is through the wheel the forks behave as one. And as you know you can have different spring rate on each forks (ex: .9NM and .95NM to achieve .925NM) Would be great to get clarification on this point. Thanks.
For the audience, the point was to ask them to pay attention when they make changes to make sure that preload settings (when there are two), are the same. With progressive springs and differing preload numbers in each leg, one leg can react quite differently to the other in rebound action based on the discrepancy. Yes, you can run split rates with linear springs and that affects ride height as they are not progressive. Hope this helps.
At 9:22 : How do you make the fork softer by adjusting the preload? I think it is just geometry you are adjusting with preload. For stiffness it should be a stiffer fork spring shouldn’t it?
He always says stiffer or softer for more and less preload, respectively. Now if that's "technically correct" is another debate, but more preload (pre-compressing the spring) does make the spring stiffer, or as he said in the video, "under more tension". 12:33 in the video.
Then the preload changes depending on what you are doing, commuting, street ride, or track. Different settings for different things, all can be viewed by the forks and the zip tie travel.
Thanks for your comment. A more technical POV would be fork ride height alteration, travel zone change or cable tie movement change. In addition, clarifying if Progressive springs are being used vs linear would also require completely separate technical statements. For the purpose of generic information, I try to cover most bases in this video. For a more technical person, of course there will be bullet holes in any video as they are flawed from their perspective and as the idiom goes, you can only please some of the people most of the time. If the video starts a conversation to inspire someone to ask, read, debate or make a change, the first step has been taken.
You are correct, nice catch as I miss spoke. 130mm was the extended distance measured and confirmed via the fine fellow that did the online research. An apology is provided for my verbal error.
@@catalystreactionsbw Must I Dave ?? Why would I need an alias ? I'm not the one pretending to be an expert on motorbikes . Having said that , I've been putting bikes together for almost 40yrs , engines and chassis , because I started working a motorbike courier at 17 . But I still wouldn't have a brass neck like you lol "Expert" lolol Pffft !!
@@catalystreactionsbw FYI Dave , I've been putting bikes , engines and chassis , together for almost 40yrs since I started working as a motorbike courier when I was 17 . I know a Brass Necked Spoofer when I see one ; )

Thank you for posting your experience!

Thank you!!
Thank you for having a go and finding a setting that worked for you!!
Dave, you are such an amazing guy. Thank you.
Thank you for watching and your kind words.
Awesome I never knew this about the suspension
Great to see new content ! Hope you’re doing better sir !
Thank you very much - being very diligent and following doctor's instructions! Feels good to be back at work.

I am sure its progressive springs so ...

Thanks for your answer. Just to add: the case study videos are really helpful for me.
2:24 You clearly say 130mm, then at 5:42 140mm.
Thank you for pointing out my verbal error. 130mm is correct.
Hi Dave. Is it me, or did you measure the unladen fork at 130mm. Then later in the video, you refer to it as being 140mm with 130mm of travel?
You are correct, nice catch as I miss spoke. 130mm was the extended distance measured and confirmed via the fine fellow that did the online research. An apology is provided for my verbal error.
'Dead space'
That's the space between Dave's ears . He hasn't a clue !! lol
I wouldn't let Dave "Expert" (pfft) Moss within a mile of my bike . He hasn't a clue . He's a charlatan !
So you must have multiple aliases as well with the same comment format> Again, thanks for sharing the insight into your daily existence.
