RDRS = No Performance Mods
Just thought I'd pass this along. Spoke with Fuel Moto and wanted to asked them - new bike - what can I do performance wise and not void the warranty. First thing FM asked is if the bike has RDRS which I replied yes. FM said slip-ons are the only mod I can do due to RDRS. Anything else you do to increase torque - the RDRS system will reduce the torque down to stock levels. They said all I can do is give my bike alittle more sound and that's it. FYI

I don't think the warranty is at question - we all know what that entails by now. OP is stating the RDRS system has certain torque limits and aftermarket mods may go beyond those limits. Then, RDRS sees that and doesn't like it so it reduces the torque back within its happy place.
Simple solution - disable RDRS (or don't buy it in the first place). To me, it's no different than putting mods on a car and traction control/stability control taking over. If you're putting the hammer down and not spinning wheels, the computer isn't going to intervene.

I kinda liked having my engine replaced 3 times under warranty vs my own pocket. But hey, thats just me being my whacky self....

Warranty came in handy when my 17 decided to eat its own lunch as well. Call me crazy, but I decided to have fun with my 18 regardless. Ran perfect, but tore it apart with only 3200 miles and after only 4 months from the time of purchase. Ain't looking back.

Interesting. This "system" is in place on most all late model vehicles. My 2007 Silverado Crew Cab I bought new had it, and they said the same thing, then Blackbear supplied me with a tuned ECM.
My '16 2500HD has it (Traction Control, Stabilitrak, etc) and I am tuned/deleted to the amount of 500/950, still works great! I call it "The Hand of God" in snow storms, I can keep it pinned and never slip a tire in 4-Hi
This is just a minor wrinkle for the bikes, it will all work out.
I think OP, and all the guys with 20s will love it after mods. I might even be jealous.
