PE175/250/400, DR500, SP500 fork yoke dimensions...?

[James P]

I am looking for some dimensions of fork yokes for the following models:

PE175/250/400 T and X models
DR500 X, Z and D models
SP500 X, Z and D models

The bikes listed above should all have 36mm forks. There are doubtless some differences in the yokes between these models, but I believe that they are all of similar configuration.

I am looking for a set of yokes (from any bike) to fit 36mm forks, which will allow the fork legs to pass up through the top yoke without hitting the handlebar. The yokes from the bikes above may allow this, but I haven't so far been able to get hold of any to check. Thus, I'd be glad of any assistance forum members can offer in this regard.

I am looking for the following info:

1. Will the fork leg(s) pass up through the top yoke without hitting the handlebar?
2. If so, what is the distance between fork leg centres?
3. What is the offset (i.e. the perpendicular distance between the centre of the steering column and a straight line drawn through the fork leg centres)?
4. What is the inside diameter of the hole in the top yoke for the steering column?

I may have to modify positions of steering stops and make other minor adjustments to suit my application, but any basic info is welcome. If you are able to provide any details, please let me know the model and year of manufacture (if you know it) of the yokes you have measured, just in case there are any differences between models.

If anyone can suggest any additional models from which suitable yokes may be sourced, please let me know!

Thanks in advance & regards,
James

I have got all this info for you but i think i may have answered your question in Kawasaki thread.

USA or 'enduro model' DR500 & 400 clamps are the same as PE175 80-81, PE250/400 80-82
They allow forks to slide up past the handle bars. They all have 30mm ofset and 180mm fork spacing. They have steering stops at the back of the bottom triple clamp and not on the top like pre 80 PE and pre 79 RM. The stems on these clamps are longer as well than what the earlier suzukis used.

SP500 81-83 is the same as DR400S and DR500 S 'trail models' and they have 25mm offset and 175mm spaced forks but none of these allow the forks to go past the bars.

The clamps you would need are 78 RM125/400 or 78 RM250C2

If you still need more info let me know

Pokey who sells those offset handle bar clamps? Got a link for them?

I was just about to ask that, but you beat me to it Matt!

Thanks Leith for the fork yoke info - I'll add it to my spreadsheet for consideration.
