MotoLink works on most Harley-Davidson bikes. There are two types of adapters available. The 4-pin adapter is compatible with 2013 and older models with Delphi engine control units and 4-pin OBD connectors. The 6-pin adapter works with 2011 and newer Harley-Davidson bikes with CAN-Bus and 6-pin OBD connectors. Please visit https://motolink.net/motolink1hd.html to check compatibility with your bike.

Please note that even if your bike is on the list, MotoLink may not work with it, if your bike was customized or has aftermarket equipment installed on it.

NOTE: This app works with MotoLink and Motorscan adapters only. Do not use your smartphone app while riding.
