Glad you did, Glenn, as you raised some important additional points.

I'd overlooked the effects of longer dogbones on the linkage ratio and spring rate. Good catch.

You're right about the fender being lower than the dust seals on top of the fork sliders, so the latter will hit the triples first. Whether the lower part of the fender would hit the rad before the forks bottom out, I don't propose to find out.

An easy way of seeing how much suspension movement you're actually using is to put a zip tie around the fork tube, snug it down against the fork slider dust seal then go ride. Do some hard braking to really compress the forks and then come home and check where that zip tie is relative to the triple tree.

DO NOT TEST THIS WITH YOUR FORKS AT THEIR CURRENT SETTING. Bad things will happen!

My forks are through the yokes by 10mm. The zip tie shows me I have about 12mm of clearance between the fork slider and the triple tree. That tells me two things; first, I'm making good use of the total available fork travel. Second, I have enough in reserve - just - to cope with extreme compression but that's all.

That's why we say 10mm max through the triples!
