By lowering the front 2" and going with a 21" wheel up front the bike will sit very close to stock height not a problem.Man just lowering the Front End only might give you some serious Head Shake problems. The Rake being longer makes High Speed better but the Rake being shorter makes High Speed more susceptible to Head shake. The old Choppers with their long Front Ends rode good at High Speed but going the opposite way could create some serious problems.
I started to mention that but you never know for sure. A short ride with the small wheel could end in disaster.By lowering the front 2" and going with a 21" wheel up front the bike will sit very close to stock height not a problem.
