Interesting. Yeah a lot of third-party motorcycle products are high. Crap ton of [reverse] engineering that goes into a product like that; which means a lot of time just in making revisions alone. The manufacturing yields are likely good but it's a low volume product; they're not going to sell very many. So they have to price it at a point that makes it worth their time.
I would certainly love an upgraded dash, in my car as well as my m'cycle. I know the car's ECU hangs on to all kinds of juicy parameters that I'd love to have integrated into an OEM dash.
