How has the performance and your bike run with Ceramic Engine bearings? I have seen a lot of feedback mostly all positive about running ceramic wheel bearings most everyone is happy how bike runs except when mention cost! I have 2020 R-1 I’m going with Rotobox 2 wheels with vortex 325 sprocket have 41,43,45 and titanium bolts with ceramic bearings. It’s about least amount rotating mass and have bling factor. I am looking at ceramic engine bearing kits. Who do you recommend? Do you know specific kit? Thank you for help.
