If your talking about an F2 or 3 then I would think the piston will be bigger to cope with the twin calliper setup. So yes, I would say it's a good choice. But you can get a reasoable result if you swap to braided hoses.
Unless you are going to change the forks as well, then you will need to go for pre F2 calipers.
If your looking for a pair of calipers, then the F1's are a good choice as they will mount onto k forks and have the bleed/banjo positioned left/right rather than front/back so you don't have to mess about swapping the holes round.
