Welcome to the forums. I would go back stock with the 21 and slow the hell down, unless you have a death wish,lol. You can use all that awesome power you have redlight to redlight and still get thrills. Good luck with your bike man, keep the shiny side up.

I have 21/17 wheels, factory tree, Progressive drop in, lowered 1-1/2" in the front and 1" in the rear, Avon Venoms with Ride-On liquid balancer. I have never had any high speed wobble issues. Ive never heard of anyone having to put trees on to fit a 21.

Sorry I disagree, this imo concentrates the stress' to a crossmember. I would install the Glide Pro swingarm bushings and front motor mount, and make sure the alignment is **** on. Works for me
