Unless those rims are also available on earlier Ryker models, so that you
might be able to get them 2nd hand from wreckers/bike parts re-cyclers, you'll probably be stuck buying OEM rims like that from BRP - and they'll likely be
EXPENSIVE,
IF you can get them! :gaah:
It might be worth your while to investigate a/mkt rims in similar styles, altho it might also be smart to look for a rim size that allows you to fit tires that have similar rolling diameters only in easier to find sizes &/or better tread patterns for your needs.

Mind you, there's not a heap of a/mkt rim manufacturers who'll make rims to suit the single wheel nuts Rykers run, but there are
some out there!

Good Luck! :cheers:
