I think I remember Papa Zook mentioning them quite a while back, maybe he will chime in here or send a PM.
2021 CVO TriGlide - Sunset Orange & Black
Life's journey is not to arrive at the grave in a well-preserved body, but to skid in sideways, totally worn out, shouting...Holy Sh!t What a ride!
Papa Zook sells Champion mechanical reverse.
It doesn't use an air pump to work like this one does. Doesn't fail in cold weather for that reason. And should mention Champion is several hundred dollars cheaper than Yelvington if the internet site is what they're selling it for.

It was a prototype at that time I was involved and we a had a working unit installed on a Roadking. The guys that backed Yelvington bought the patent and the Roadking with the working prototype installed on it from the inventor after a chance meeting with him at the Aim Dealer Expo in Indy. It was a cool design and they got it for a song, but it needed mods and R&D to make it safe. The original unit used a lever to manually set the reverse gear inside the rear pulley.
There was not a problem with it engaging, but there was a potential problem that concerned us. We were developing and testing the use of hard rubber friction wheels to replace the metal gears, so in case it did accidentally engaged it would slip and not lock up the rear wheel. I left before the final product was released, this was back in the fall of 2012.
I would talk to Yelvington and get the phone numbers of multiple bonafide customers before I purchased one, or better yet use Google.

Yelvington will void the warranty unless it is installed by a certified Harley mechanic and I read that most Harley shops will not install it due to liability.

WOW, this is a VERY intersting read
I just learned some stuff I did not know
I just cant think of any good reason other than cost(BEAN COUNTERS),
that HD would not bring in a real tranny with reverse like they had with the hand shift Fl and the Servi Cars back in the day
I worked on a few of those CRUDE trannys, they were bullet proof, tho the gearing was WAY to steep between gears JMO
