Apart from the grammar issues, I found the description persuasive, enough to risk the $124. That price seems low, actually, for what's received if it's as advertised, but we shall see.
Winter has closed in on us early and the GSXR has been sent to storage. It's not likely I'll be able to do much more testing to see how it works out, but so far, so good.
