I have ASV F3 levers for two of my bikes, an '12 RMZ450 and a '00 YZ250 and I love them. I bought these for my 'new' YZ250F because the F3 lever package wasn't offered. These things are trash. They don't fit, I had to fight the hot start cable in and the clutch cable is adjusted all the way out and still has play in it. Also the lever isn't tightly matched to the perch and has a lot of rattle. Small issue is they don't look as good as the F3 lever.
On the up side the brake lever fits just like the OEM lever and works really well.
