I was booting it to PEI yesterday..... hitting speeds of 140km (down hill) lol..... only problem I have found is that the mirror is a tad bit small..... ans have had to tighten the adjustment screw twice. This puppy won't bend......

 

I use the same mirror I had it threaded up about another inch, they work great for crusing but around 80kph they tend to vibrate a bit but still work,
