Y'all gotta start doing Slingshots. They use the same engine with a 5 speed transmission. I'm ready to do a stage 4 build on my 2020 R but there is no aftermarket support yet. I'll have to get RZR Pro R stuff and I still don't know if the tuning option for the Pro R will work on the Slingshot.

Love it

[@Hondarider35]

I’m very excited about the power you guys are making on na motor. I can’t wait to get my pro r tuned. How much does the stage 3 tune cost?

[@erranmayfield7031]

Would this be considered reliable HP. Still have longevity in motor.

[@JoeyStrub]

This would be more race only. We do have a +1/+1 mm with .430 lift cams that would be reliable like stock.
