This kit will accept your stock starter or one of Tech’s Tornado starters. If your bike has a fat tire with left side drive, up to a 1” offset can be machined into the motorplate to accommodate your needs (spacers are available for offsets greater than 1”). Kit is available in a machined or polished aluminum finish, with chrome plating available by request. In addition, if you are running a right-side drive setup, a motorplate featuring a custom side contour is available to clean up the look of your bike.
