Will the stock casing for lights and key fit with renthal bars on 07 z400?

 

Do the bars have a riser or are they bolting onto the stock clamps?

 

stock clamps

 

The stock the assembly will fit. You might have to modify it a little.... my buddy runs Renthals with the stock key/light house, he just had to twist it backward and use tie wraps to hold it in place. So now the housing is somewhat angled back instead of sitting straight. I saw one guy at a race once that had Renthals with a riser, and he had mounted his key/light housing to the bars so that it was laying on the gas tank. He trimmed off like 2" on the housing and contoured it to fit into the space. It was really trick and totally simple enough to do.
