monoshock linkage questions

[johnnay]

Can anyone tell me the reasoning behind the linkages on the GSXR's - why aren't the shocks just placed in a direct line from the swingarm to the frame, like this:

The linkage changes the leverage ratio.

So it's just so you can use a lower spring rate? seems complicated if that's all it's there for - there must be some other advantage, or manufacturers would just go with a (cheaper) stiffer spring rate, and avoid the cost of all the linkage, no?

Just trying to wrap my brain around it...

You can get more wheel travel out of a shorter stroke damper.

cool. thanks for your replies!
