BMW R nine T
Last time I wrote that I was happy with these guards and gave them 5 stars. Now I have to admit that these guards probably do a good job at very low speeds but at speed above 10-20 mph they just don't work or even damege the engine's Intake system. I laid down my bike on the left side when I was hit from behind by other motorcycle on a highway. The guard was ripped off and bent so badly that it cut off throttle intake manifold but also the engine head valve cover was scratched almost everywhere. Maybe the guard saved the valve cover from cracks but it broke the throttle so I wasn't able to ride the bike back home anyway. It was the worst damage to my bike besides broken Rizoma mirror and few scratches on exthost pipes, handlebar ends, clutch level and headlight. I wish I'd better bought crash bars instead of valve cover guards. Waist of money.
