Well it turns out that TREX was wrong...their 2006-2012 gaurds do not fit Gen 1 bikes. after receiving the frame guards a few days ago.. I decided not to install. It seems that I would have to cut about a 2 inch hole in both sides of my fairings. More then I feel comfortable doing. I called TREX and will be returning the guards in exchange for their sliders. They said they have no plans in designing gaurds for our Gen 1 bikes. Bummer..I really wanted them to fit! They are very well built guards. I'm curious how R-GAZA guards mount up since both motor mount bolts, on both sides, are behind the fairings on Gen 1 bikes.
