Anybody here ever put one of these on their dirt bike http://www.bikebandit.com/koso-xr-sa-motorcycle-speedometer or http://www.bikebandit.com/koso-gp-style-multi-function-rx-2-motorcycle-gauge ??? Second one with the big sport bike tach looks awesome, check out videos on youtube of it working... it is definitely pricy though, but I'm just trying to see what alternatives there to the trail tech stuff. I think it would be great for anyone with a street legal bike, they both even have odometers. If anyone has used one before, tell us all what you liked and or didn't like.
