Forks through yokes?

Stew · Posted: 18:52 - 30 Apr 2003 Post subject: Forks through yokes?

Okay as many of you know I bought my YZF750 in November. I realised a little while ago that my yokes seem to have been dropped down the forks quite a lot (16mm). I have read that doing this improves the bikes turn-in speed but would affect the stability. Does 16mm of forks showing through the yoke seem excessive? And should I raise the yoke up to a more sensible height. I havent really suffered any problems with the handling (kneedown seems fine etc) so I am tempted to leave it as it is. Any suggestions?

You are correct it will improve the turn but straight line stability will be affected.
the max drop should only be 10mm 16mm will give no advantage to turn in over 10mm but will seriusly affect straight line. somewhere betwwen 5 and 10 will give a good compromise. I would suggest you reduce the drop to around 8mm and test. I think you will find it turns in just as good as it does at 16 without stability probs.

Talk from experience here. you are more than welcome to disregard my comments

It may make it more likley to tank slapper etc, I believe.
I've got mine dropped a fair bit at the mo (did it when I was expecting to go to elvington on it Confused

) I've got a steering damper as well, which helps on bumpy roads Smile

If you have higher profile tyres (ie race tyres) then to keep the same height you do need to drop it slightly.

Though ... as they say 'If it aint broke'.

I'd be more concerned about the fact its moved down 16mm on its own Confused

It hasn't dropped on its own, its how it has been since I bought it.

And thanks 'biker' I think i will do as you say and reduce the amount of fork that is showing through the drop. drom what I have read, loads of people have dropped there forks through by 10mm on this particular bike as it is regarded as being very stable and the reduction in stability is outweighed by the quicker steering.

The problem I have now after looking at it is that one of the allen headed bolts on the fork leg seems to be a bit rounded off Confused

To be honest Stew, if you have been riding it since November with no problems then leave it alone.

I am going to go with the settings as suggested in Performance Bikes set up guide for the YZF750 and see how that feels. Thats if I can manage to get the bolt out (the bolt has rounded).
