Can someone tell me what benefit they provide other than weight savings? (for track of course)

 

if a stock clip-on breaks in a crash, you have to replace the entire clip-on but with aftermarket ones you just swap out the aluminum tubes, and because they pretty much all use the same size bars, its easy to find a spare tube in the paddock. Try asking around the paddock for a stock F4i clip-on sometime...
lol

They also don't have as much weight, so you can get a better feel through them
Woodcrafts also have a two peice base so you don't have to remove the top tripple clamp to remove them (if your putting them below the tripple

the biggest advantage is that you can move them however you want much easier than stock, most stock clip-ons have a tab or something to keep them in one position

thats all I can think of at the moment

 

Do you have them on your racebike?

 

yeah, I use woodcrafts below the tripple on my F4i
can't turn the bars nearly as much like that but it puts you in a much better position for track riding

 

I agree with Woody, clip ons are one of the first pieces to snap in a low speed crash, going with a aftermarket clip on like Woodcraft makes fixing after a crash a one or 2 minute job. I have woodcrafts on my cbr and they work great.

 

oh yeah one more thing, most clip-ons will have a plastic slider made into the end of the bar that helps a lot in simple lowsides
