Hi all, never having played with an adjustable steering setup on the 916/999 etc, how does it work? does it have set positions or is it a suck it and see? does it pivot about the bottom or does the whole stem rotate? I know absolutely nothing about them so please could you all fill my boots!
2 positions, standard and race I believe. I think the steeper angle is only advised alongside the longer swingarm the race bikes have. Other than that leave well alone was the advice I was given. However there are plenty on here who know, @Cranker V2 or @bradders would likely know.
It's both clever and simple Sev, the fork bearings are mounted in a 'sleeve' which is locked in the headstock in one of 2 positions. It's set at half a degree from being 'true' to the headstock tube so by swivelling 180 deg to the other setting you can change angle by 1 deg. Nothing wrong with using 23.5 deg on the road and doesn't take long to adjust in both senses but bear in mind that you can't use steering lock on some models
From a 999 standpoint - say that you have, for the sake of argument, already quickened the steering by raising the rear ride height, dropped the upper yoke down a few rings and swapped the standard 190 profile rear tyre for a 180. If you then introduce the steeper position of the forks, you may have a very quick steering but unstable set up. If you dial back on the other measures, you may get some stability back. (I imagine, correct me if I'm wrong.) Undoubtedly, there will be a sweet spot for you by combining all possible measures to varying degrees but that sounds like an awful lot of work. Can't wait to get started
thanks to all So, the eccentric is the tube and that is clamped in the steering stem. The tube is rotated and then clamped again in one of two positions. Chris, you're right very very clever, and the bearings resident in the tube is pretty trick also - saves the cost of fancy bearings and probably makes the process of extracting them easier as well. So does the sleeve have a lock stop / detent / bump stop or is it just aligned with marks?
Had my sps in race as I just felt it made it easier to turn but you lose lock and steering lock Cranker and chris onow their stuff. I know shit. Just ride em

Don't bother playing with the head angle if you don't have the relevant offset yokes. From memory std yokes are 36mm and you need 29mm if you spin the eccentric 180. Also if your on a 916/996 etc you'd ideally need the longer Corse swing arm. I had a hilarious conversation with a guy at Donington this year. His " suspension guru" had swapped the eccentric on his 999 round claiming it was the trick setup. All it did infact was tank slap and handshake it's way round the first two sessions. Before he asked what setup I was using. Unless your Troy Corset keep it simple. Get the basics right. Sag, springs, maybe drop the yokes down a ring or two. Make sure your using 90% ish of the front travel. Then ride the bigger!
