Are there one or two spacers on the front wheel of an 06 600 rr?

 

The 07 has two, one on each side that goes over the axle and against the dust seal keeping the wheel centered in the forks. I would imagine the same is true for the 06, as this concept is pretty standard as far as I know. Check the service manual, or go to hondapartsdirect.com for a breakdown of the front end and just look.
