I have owned my C50 since February this year and am very happy with it. I had gone 35 years without owning a bike and it sure is good to get back on one. I wanted to get a wind screen for it so to check out what it would be like I bought a cheap one size fits all and got terrible harmonics from it. It nearly caused my teeth to fall out. It shook my hear terribly no matter what height or angle it was on. My question is, do the authentic Suzuki screens cause any problems like this?
