I have the ASV C5 shorty's as well (brake and clutch) had to swap out the micro-switch to a pressure switch for the front brake light and drill a small hole and insert a press-pin to keep the brake lever from flopping backwards.
The clutch was a breeze to mount although I did machine both OEM pivot points down so that I could use the stock handguards but I lost use of the clutch safety switch.

Are the Zeta's a direct replacement that require nothing other than bolt-on?

 

THEY WERE A DIRECT FIT TO THE PERCH.

 

Well the Zeta'a are the way to go then for the KLX.

The photo worked fine but aren't your hands a little small for those short levers?

 

Actually Dave those are shorty hands and standard levers. I've noticed that not much gets by the regulars around here and there's nothing wrong with that. Was just trying too make sure I knew how to embed a pic in a post and figured I'd use an old thread that nobody would see.

Live and learn - a daily ritual....

 

What are the correct part numbers for the zeta levers?

 

wondering if I purchased asv shorty leavers will they work for my 2012 klx 250 ?

 

Look up the part number for the Kawasaki lever on Partzilla, then look to see what all models use it then look up aftermarket levers that fit those bikes. I kind of doubt Kawasaki has made a different master cylinder or clutch lever for the KLX250s. Probably the same as all the 300Rs and possibly some of the KXs. I'd look, but I just cut my levers off and they are tucked inside the handlebar guards, so I don't have a need to know.
