650-XSories can supply a number of unique parts for various XS650 models.

Like alloy Disc Calipers for the XS650C or one piece clutch push rods.

Or seal kits for installation with the crankcases closed or open. Install these and you'll never have split the crankcases again to replace those seals! 

Or an alloy brake fluid reservoir for your XS650C

New crankpins for 533 motors are also available.
