You can check all my review on the forum I update the post. The biggest downsize is a high pitch sound like a transmission on race cars. I suspect it's from the fact that the front sprocket doesnt have rubber like the stock one to dampen the sound.
Yeah those mirrors are really amazing for the price. Glad I still have both, I just missed a deer by a few inches an hour ago...luckiest animal on earth...oh and so was I!
No chance on keeping up with a z1000 hehe.
Probably went around 215km/h too. Technically it should go about 230km/h but would take you quite a long stretch of road, and maybe a 5km/h rear wind...I also think when the speedo is showing 215km/h were probably around 200km/h in reality...
