Raldes do one. My dad has it for his kitcar. Its a Bike speedo, runs of a wheel sensor. Pretty decent piece of kit for the money.

Clicky (http://www.rallydesign.co.uk/product_info.php?manufacturers_id=77&products_id=13584&osCsid=p0s2e1o87mk2qg6i9j23kq0d63)

Or a cycle speedo? Same kinda thing but much cheaper and many to choose from.
