Longer Magura clutch lever

Do you guys know what clutch lever is stock on the 2010 Fe450/390/570.I came up with three levers (short 123mm polshed #20-0723121) (Long lever polished 20-0723290 146mm)and their is a black 163mm #20-0723296. I believe the stock lever is the short 123mm and its to small for my big fingers.Has anyone ever purchased the larger levers and have a place to purchase one,Thanks Mike

Ok guys heres the deal! The stock Magura flex lever that came on my 2010 Husaberg FE450 is a shorty part# 20-0723121. Ive always disliked the lever for being too crowded.The finger well as im calling it measures 50mm on the stock shorty lever but Magura sells a standard length lever/blade that has a 70mm finger well that they call 146mm Part#20-0723290.For reference the stock clutch lever on my 01 cr250 has 70mm finger well which fits a large hand better.I know lots of you ride using two fingers on the clutch but at the end of the day ive always liked the longer levers.Ill put up a picture of the stock lever with ruler so you get what im talking about when i say finger well.I couldnt find this info anywhere on the web but did see these levers being sold in Europe so that's why im posting to help someone else out that might like a little longer clutch lever.Heres the number for Magura USA(800)448-3876 you can order direct.
