I'm in need of a set of brush guards for my 08 F650GS. I want them primarily for rain protection for my hands. I live on Vancouver Island and it's going to start raining here soon for about the next four months. The BMW guards are $250 here in Canada, Tourtech are about $200 with the extra extension piece and shipping and Acerbis Dual Road Handguards $111. They seem small. Anyone want to wade in with an opinion? Has anyone fitted the Acerbis guards? Has anyone installed the Tourtech gurads - with or without the plastic extension?
