GIVI PLR450 Rack -- take care!!
Took my first ride with the GIVI PLR450 side case mount brackets and the E22 side cases. First of all there was some difficulty getting the brackets attached to my 2014 650 (with the 'Speedy' lowering link). But, after some 'tweaking' in the vice and forcing, I got them attached.
On the ride, with my 130 pound wife on back, I soon found my rear suspension bottoming out on bumps that weren't that severe. It turned out the tire was hitting the center fastener of the GIVI bracket arms that run in front of the rear fender (between the fender and tire, connecting the left and right side assemblies). Fortunately, GIVI had the common sense to bevel the head of this fastener, so there was no tire damage. After cranking up the rear spring preload, I didn't experience any additional bottoming - - - but, I really didn't encounter hardly any bumps that would cause bottoming.
So, keep in mind: You may have to crank up the rear spring preload in some circumstances when using the GIVI PLR450 brackets.
