Didn't magpul buy up 50 or so of them for the ronin?
Are there any other known issues I should hear about or customizations I should research?
I went long and hard learning the Cr before I got mine, I was ready to get an Sx when the company shut down and the reliability of the R and Cr took me back instead of forward, that said, there is a possible issue with the crank nut, has come loose a few times on the R, Cr , and same seems to happen still in the Rx Sx versions of the Rotax.
Nice thing is there are parts available to fix, St Paul HD, Fleabay a few good members here are reliable US sources along with a few HD Stealerships for basics.
Customizing is another area where parts are lacking unless you can fabricate. Carbon fiber is available for the tail, belt and some engine covers, screen, fender, scrubber, and airbox. Brembo upgrades to the master cylinders are trick, Jens sells a fair assortment, actually more than any other and ships to the USA ...
