ABS bleeds works perfect with my FATBOY M8 114. No vin binding and no internet connection. !

Interesting tool but will not perform abs brake like it should even with latest update, updated twice to be sure. Would do front brakes on 2020 softail but not the rear and would not work at all on 2021 Streetglide. I reached out to FXTUL and they were going to discuss it with the engineers but did not hear anything back for several days. Does have the capability to read and clear codes but on Harley only. The OBD2 side can read vehicle codes but cannot clear them. It may work for older J1850 bikes for a scanner and abs brake bleeding but will not do so correctly on 2020 up models from my experience.

I've been using the M4-ASIA motorcycle diagnostic tool in my workshop for a few months now, and it's been a game-changer. It supports all the major Asian brands like Honda, Yamaha, Kawasaki, SYM, and KYMCO, and the connection process is fast and stable. The interface is clean and easy to use, even for technicians who aren’t very tech-savvy. I especially like the service functions like TPI Reset, Idle Adjustment, and Throttle Learning ?they’ve saved us a lot of time. The software updates are regular and customer support is responsive. Highly recommended for any professional motorcycle repair shop.

This Harley motorcycle diagnostic tool is easier to use than I expected. I like its appearance. During the process, I encountered several problems. The customer service staff Winnie actively helped me via email, and I also successfully used the service function.

Herramienta muy completa, no necesita vinculacion a VIN o internet. Acaban de actualizar a version con funcionalidad de ABS BLEED de harley. Muy contento de momento

Luis P.

Product apparently of good quality.
It can read the modules of my 2021 Fatboy HD without any issues. I haven’t tested more functions yet. I’m waiting for the ABS Bleed function to be available so I can do brake fluid changes at home. The device offers free updates and is not linked to your VIN. So far, the support has been good and they resolve your questions efficiently.

Jack B.

The product works well and is easy to use. But some of the cables for the connectors are showing exposed wire

Jack

It works great for resetting the service light on Harley-Davidson motorcycles! Plus, it’s very affordable—getting lifetime free software at this price is a real bargain.

Andrew R.

Works perfectly on my 2019 softail, I bought it because of the abs bleed capabilities and it does it without any problems.

Selena F.

This diagnostic tool is a game-changer for Harley maintenance — fast fault reading, live data streaming, and deep system checks. Easy to use and great value, it saved me time and money versus dealer diagnostics. Works on multiple Harley models and gives accurate, reliable results every time!
