Models and years
This document explains how to connect AiM devices to the vehicle On Board Diagnostics
(OBDII) data stream.
Supported models are all motorbikes and mopeds produced after 2020, or in any case those
declared as Euro5 compliant.

Wiring connection
New motorcycle models, from year 2020, need to meet stringent ‘Euro 5’ emissions laws, this
also means they must provide a standard communication protocol and a standard connection.
The new On Board Diagnostic Connector for motorcycles and mopeds (OBD - ISO19689:2016) is
what you will now find on most of these bikes and it is also described here following.
The red JST 6 pin female connector is generally located under the bike seat or close to the
instrumentation cluster.
The standard OBDII protocols used through it, are based on CANbus or on K Line.
Below you will find the connection table and the matching male connector.
