I have the Pro-One Tach and risers on a 08 RS
this is my 3rd season with it. I have to say the chrome looks like brand new. When I first put it on the bike the handle bars were crocked. So with a little investigation I found that the risers were at different angles so I made a call to Pro-one and they replaced them, no questions asked. In two days I had a new set of risers and an Apology from Pro-One for the inconvenience. That's customer service!
I say go for it. I don't think you'll be sorry.
