No, Track mode can not be added to other models.
Stock speed limiter is 104 mph
Street Tuner speed limiter is 108ish mph

 

I can confirm that the CVO ST is fully capable of that 120 when it is still bone stock. 🤦‍♂️

 

And I can confirm that I did not confirm his claim of confirming this 👮‍♂️🚓

 

Can track mode be placed on a different bike? I'll be getting a 25 CVO RG. Can any one confirm what the limits are on a stock 23.5 or newer bike or using Harley's tuner.

HD Tuner is garbage, I have one in my junk drawer, in your mode select you have A/B that you can customize, choose A and Max everything out, you’ll thank me later, My 23.5 has no nanny as far as limiter or jiffy stand, I have removed both using the Impact wiring ECU, OH btw it gets to 120 very quickly
