Suzuki SV1000 2003 rotor / flywheel. This has all magnets intact, and has had JB Weld applied to keep the magnets in place. Prized item. OEM 32102-16G00 is $680 and still needs to be JB'ed from new.

This will fit all SV1000 years, but is heavier than the 05 up unit, but can be machined to near the same weight.
There is a schematic of how to do this on the site posted by estevns (member)
