Last night I received and installed the Superbrace I bought on ebay last week. It came as advertised with the correct hardware. After my morning ride, I am fairly confident that, while it is a very nice, hefty, shiny chunk of aluminum, it did nothing to change the handling of my 87 VR. My bike has the same slight propensity to mid-speed front end wobble and high-speed weave that it had before, and other than that handles fine. Exactly the same.
To quickly review, I've been through all the suspension bearings on the bike, have 2 new tires, double-checked the stem bearings. Thru all this, the high-speed weave, which is NOT self-amplifying, reduced a little. The mid-speed wobble up front (which IS self-amplifying) was mostly taken care of with the new front tire, but not completely. Maybe I need to double-check the balance on the tire.
So, it is my opinion at this point that a Superbrace on a VR is a solution looking for a problem, and not the solution to the small problems I do have.
