It is what you want. It gets rid of the annoying pointy tendancy to be squishy then kick you up the *rse. It probably made sense for suzuki to do it but when you've got an aftermarket shock it means that the end of the suspension travel is effectively set up wrong.
Curvy linkage doesn't work on pointy.
