depends on "needing any mods" definition and how you want to position them.

I had to cut a tiny bit off the right one due to the front brake fluid tank. Then i had to file a bit of the clutch lever so i can position the left one as I like. Handlebar weights can stay on without issues and otherwise I'm pretty satisfied with them... IMO spending too much protecting levers ain't a good idea considering the price of the levers. For the rest of things like protecting them from a low speed or when laying off the bike or branch protection I'd say they do the job well.
