Too big. If using during snow plowing they are a burden due to need to take hands off controls, and shift from forward to reverse. Might be okay if just riding around on trails, etc.

Good quality, not great on clutch
The quality of these is very good. They break the wind very well. Too well, actually. On my bike when going above 60 MPH they press hard enough on the clutch to be a problem. I'm sure I'll still use them but they won't be of any value on the interstate. It's possible to hold the clutch while using them but, for me at least, I don't have the strength to do it for my 45 minute commute. Unfortunately, the openings seem to fold up making it difficult to get gloved hands into them quickly, which is my reason for subtracting a star.

I installed this on an e46 325ix sedan, they only worked, one of them is just a little loose. I don't know how long they last, because every time I open the bonnet, the lever bothers me a little?
