99-02 Rear shock chart

[CSpronken]

I noticed that myself and others were struggling to figured out how their weight and driving style related to the standard and other shocks and their preload settings. So I started to make an excel chart of it. As I myself am not in the least knowledgeable enough to make this "correct" I need other peoples input to make it useful.

The chart is for a curvy with normal sporty driving, but not on the limit. Rear height is compared to normal height of the stock shock with properly set sag. If you think this chart might be useful for people or perhaps plain rubbish please comment. A pointy version would be welcome as well.

I'm not sure that would be of any use to someone who's willing to do a bit of research. I know roughly what I'm on about with these things and I find it a little hard to follow.

The ride height on all those shocks comes in at "way too low"

Well to be honest I've been searching my butt off for the last week and apparently I still don't have a good feel for it. Others might feel the same.

With normal height I meant the height that the standard shock would be on with say a 60kg rider and the proper sag amount. If you reckon that's too low for sporty driving, I could adapt the chart to reflect that in some way.

In the other thread you mention a 350+ mm shock, vs. the stock 337mm. With an 1:1.8 ratio that's 23.4 at the rear wheel, with rake changing from roughly 25 to 24 degrees? Sound good for very sporty driving, perhaps a bit steep for touring?

would this be the same for pointy models aswell? looking a a zx10 shock for mine as heard there pretty much bolt it, just removing a little bit of plastic

Nah the bike is still very stable, even with GSXR forks an inch shorter. You can go much longer than 350. I tried around 360 but it felt kinda strange, set it somewhere about 355.

Laden with pillion and luggage, the reduction in squat because of swingarm angle may make things even better.

Have a look for Gixxer shocks for the pointy, not ZX10. Do a search on the forum there are loads of threads on here about it.
