Goog product for a good price.
Easily installed it on my 2009 FZ6R Yamaha. Of course it is not the same as an electronic cruise control therefore changes in speed will happen going down or up a hill (between +5 mph to - 5 mph to set speed). Fuel economy on highways improved by about 5 MPG due to the throttle assist. Averaged 59+ MPG on last tank (highway).
