For Kawasaki Versys V650 owners looking to tap into their motorcycle’s diagnostics and performance data, using an OBD2 reader with the Torque app is surprisingly straightforward. Despite some online discussions suggesting otherwise, connecting these tools is simpler than you might think, especially when you understand the fundamentals of your bike’s diagnostic system. This guide breaks down the process, focusing on direct connections and essential wiring for a seamless setup.
The key to connecting an OBD2 reader to your V650 lies in understanding its 4-pin underseat connector. This connector provides the necessary lines: 12V power, Ground (GND), and the crucial K-line for data communication. Forget complex pre-made cables for now; we’re going back to basics to ensure a reliable connection.
Here’s the pinout of the V650’s diagnostic connector (viewed with the key at the top, from the front):
K Line GND
L Line VBATTo interface this with a standard OBD2 car-style connector, you’ll need to make these connections:
- OBD2 Pin 4 & 5 (GND) to V650 GND (Black/Yellow wire)
- OBD2 Pin 7 (K Line) to V650 K Line (Schematic shows Pink/Blue, often looks Purple/Violet)
- OBD2 Pin 16 (12V) to V650 VBAT (Brown/White wire)
If your OBD2 connector has an L-Line (Pin 15), you can optionally connect it to the V650’s L-Line (Light Green/Black wire), but this is often not necessary for basic Torque app functionality.
For this DIY approach, creating a patch cable is ideal. You can use an OBD2 socket and a compatible 4-pin Honda plug from electronic component suppliers or salvaged parts.

Once your patch cable is ready, connect your OBD2 dongle and pair it with your smartphone running the Torque app. With everything connected correctly, you’ll gain access to real-time data from your V650’s engine control unit (ECU).
