I am looking at one when I re-wire my XS400 Street Tracker. I am having a million issues with the wiring right now (hacked up harness) so I just want to re-wire the damn thing. The Motogadgets M-Unit looks like it makes it easy. Pricey though.
I have a bit of experience wiring them up on custom bikes. They’re pretty much flawless. My only gripe is the programming which works fine but I think it’s annoying.
I've used M-Unit Blues on a couple builds. One on my personal bike. I really like them. I use their switches and M-button it really cleans up the wiring to the bars. The keyless start function adds to the cool factor. The only complaint I have is about the wiring. To me it would look much nicer and be a more robust connection if they used a type of sealed standard ECU connector rather than the stab connectors.
