I bought a Chinesium lock set for the SV as the ignition lock was a bit worn: I didn't fit it in the end as I learned the trick to get the original to work & gave the set away to the new owner.
It seemed OK to be fair, and was about half the price people wanted for used originals & there was no way to know they were any better than the old one. I would probably have fitted it as the bike was leaving, but maybe not if it was a keeper.
