Here is an easy way to see what hits first without getting any road rash on you or your bike. I use this method when ever I change foot pegs, exhaust or suspension parts, i.e. lowering forks or shorter rear shocks, phat low profile tires or going darkside.
You will need a sheet of plywood 4'x8' or anything flat and about that size along with a friend as a helper.
Either you or the friend set on the bike holding it straight up with the side stand up, next place the 4'x8' plywood parallel and against the sides of the tires flat on the ground.
Now, with the bike perfectly straight up and down, you or your helper lift the plywood up and see what it hits first on the bike, you will want to do this on both sides of the bike.
What you are doing is imitating the lean angle of the bike by making the plywood the road.
Tip; The person on the bike should have as much weight on the bike as possible to spring the suspension. You can do this on the center stand, but the bike is not at the proper height as it would be if it were rolling.
This is a good test when changing to aftermarket foot pegs, exhaust so you know the lean limits without causing and damage to you or you steel steed. You can determine what hits next as the foot pegs fold up when scraping by continuing to lift the plywood.
