As far as warranty - at a couple weeks into ownership I am not ready to throw away 2 years worth of warranty. Especially after having read some of the issues others have had however rare those may be. A year to year and a half down the road at that point I may feel perfectly comfortable doing things that could cause a warranty issue to be denied.

We did not get to discuss the warranty aspect of what can or can not be done. It was very simple - if the bike has RDRS anything that is done to increase the amount of torque produced, the RDRS system will work to reduce the torque output to stock levels. I tried to point out that I was going to use the SEPST for tuning since I already knew that Power Vision at this time is not compatible with RDRS. Same answer - if torque is increased RDRS will reduce it.
Which is why I made the post here. I wanted others to be aware if they are thinking of purchasing a bike with RDRS it may severely limit what mods can be done to the bike. And I was regretting purchasing a bike with RDRS.
Now as others have pointed out it is possible for an RDRS equipped bike to go beyond stock power levels.

I am not so sure he doesn't understand as much as he was told it reduces power back to stock level by FuelMoto which is why I said in mt first post he was misinformed. You and I know better but I do not think, he did, at the time he was told.

This is exactly how I initially thought rdrs would operate but was told otherwise by a very reputable source. hence the post. And thanks to input from people on this I now know it operates as you stated.

The ECM's have been set with it for years on most all the Electronic Control Throttle models but they did not start Traction Control until 2019 Trikes. You must use the ECM Torque Control mode for the Traction Control to work. So in 2019 you only had to worry about Trikes but now it's been added into the Touring models equipped with the RDRS system. Guess those that cannot do it now, have not been doing any 2019 Trikes either. It's not new by any means just different and once you sort it all it works rather nicely. It adds more time and work into getting it correct, that's for sure, and you cannot just cut, copy and paste tunes any longer.

quite a few features included in RDRS and the HD site has some good info videos illustrating how they operate / function as well as descriptions..here's another new feature....most of these features are only effective in those moments where the operators are making mistakes, poor judgement or riding really aggressive imo..good stuff to have but after riding for many decades I doubt I'll regularly give these a workout...the cornering ABS I think is especially valuable as who of us hasn't come into a corner to hot and had no choice but to scrub off some speed or hit a guard rail or something....nobody rides 100% perfect all the time
DSCS is standard on all MY20 CVO™, Police and Trike models and optional on all MY20 Touring models in the U.S. (except FLHT).
When DSCS detects excessive rear wheel slip under deceleration it will adjust engine torque delivery to better match rear-wheel speed to road speed.
DRAG-TORQUE SLIP CONTROL SYSTEM (DSCS)
Drag-Torque Slip Control (DSCS) is designed to reduce excessive rear-wheel slip under deceleration, which typically occurs when the rider makes an abrupt down-shift gear change or decelerates on wet or slippery road surfaces.DSCS is standard on all MY20 CVO™, Police and Trike models and optional on all MY20 Touring models in the U.S. (except FLHT).
