View Full Version : Suspension Lowering Tie Bars:

Does anybody know what the centre to centre measurements are between the bolt holes for the lowering tie bars on a curvy SV? Are they any different for a pointy SV? The standard ones are approx 115mm. Can anybody tell me how much 10mm longer lowers the suspension and would 20mm lower it twice as much?

Somebody please correct me if I am wrong. But longer bars will actually jack the rear up further not lower it.

Ape, longer bars lower it since it actually pushes the mounts away from the shock assembly, fitted them on mines and got the height down about 3/4 inch

You would have thought I would know better. I have shorter (must be) to raise the rear on mine. :oops:

Ape, yep, thats what I thought originally, was totally confused and thought SVMania had sent me the wrong ones :oops:

Woman on phone must have thought I was a proper t!t :shock:

I hear hayabuas ones are a direct swap for a lower rear end. That might be cobblers.

Hey folks, just resurrecting this thread to ask the same question again:

does anyone know the centre to centre measurements for the pointy dogbone lowering kit ?
Any and all help appreciated :)
Cheers.

As far as I know, this is not on the sv - the lenght of the tiebar is not directly proportinal to the change at seat height because the effect of the linkage. It normally gets multiplied from the lenght of the tiebar

I would think 20mm longer at the tiebars would produce a big drop on the saddle

this might all be rubbish sorry if it is

The linkage is what they call a "rising rate linkage" to give something similar to a progressive spring action in the shock, sort of :-P (I'm no suspension expert)

The actual change in seat height is going to be different to the change in dogbone length, due to the lever action of the dogbones on the swingarm. They're also at an angle rather than straight up.

Pretty simple to figure out if you know all the dimensions and assume the shock is rigid (like you do to when you measure seat height)

No idea what effect the different static angle of the swingarm has on the leverage on the shock though.

This is what i measured when I brought my lowered bike back to stock:

original dog bones have holes drilled at 145mm centres. Mine are drilled at 170mm centres and drop the seat height from 31 1/2" to 30" so 1 1/2 " drop (or about 40mm)

03 pointy.

I do still have these dogbones in my possession :)

I think the stock dogbones for a pointy are 150mm between hole centers. They also have '17G' stamped onto the side of them. Thats measurements taken from a K3.
