My yz450 is capable to run a headlight, and I like the look of the WR headlight the best out of all the aftermarket ones. I can buy the assembly for about 200$ and according to the fiche it looks like there are a couple of mounting bolts on the lower clamp. Is there enough room to drill and tap my existing lower clamp or does the WR use a special clamp? Is there anything else that I should be aware of? I appreciate your help, hopefully I can have the information I need by monday in which I will order the assembly.
