well its on the bike, and I have to say it looks the bomb, just cleans the front end right up.
As Keith says, they come with a bracket and can be mounted on the handlebars if you want.
I got the 2856 model, which is the same as Keith's only it has an LED display rather than the bulbs and like Keith's one, the dispay is useless in the daytime, in fact I reckon the LED version is worse.
Takes a bit of getting used to as it sits in the tank and is not on that much of an angle, but after a morning of it, its all good. Once I get the Tbars on I reckon it will be even easier to see as the riding postion will be further back and better with the line of site.
I used the adapter straight onto the speedo cable and tucked them under the tank, setting it at around 725 mark seemed to have the speed about right.
Once I get the T bars on I will post some pictures
