NWRider;58788 said:This is the same problem mountain bikes had for a long time. There are many ways to make a single pivot a falling rate which makes the problem worse. I heard a couple years ago that KTM changed the shock angle to make it more progressive. But the theoretical best a single pivot can do is be linear, it can not have a rising rate.
I’ve been off the mountain bikes for a few years but I think they have overcome the problem. Some of the newer shocks have the rising rate built into them with complex damping and/or air chambers I believe. I don’t know if this would work on a dirtbike though.
I always notice the problem when I ride a KTM. They can make the shock seem progressive for a big and fast hit. But for a G-out, like when sitting and rolling through a large dip in the ground, the shock blows through it’s stroke and then the bike steers like a chopper. It scares me! I have never owned a KTM though so maybe it the suspension is setup exactly for me it would not be a problem. But with a linkage it is much less fussy. For example I am 200 pounds and I rode my WR125 a few times with stock springs. It sat low but other then that handled fine. If I ride a KTM 200 with stock springs (which are about he same stiffness as a WR125) the bike handles really bad. Proper setup is probably a lot more critical on a KTM. Maybe if a company other then WP took a crack at the problem it would be solved?
Good stuff Mark
