Installing a 21″ front wheel is one of the most popular conversions to greatly improve the look of of a Bagger. This post is not about the wheel design choice – all manufacturers offer a wide selection – but about preventing any handling side effects due to a taller size than stock.
First, you should know that the Bagger chassis don’t like very much extra rake. Experience shows that a 21″ wheel may make your front end feel heavy at low speed while turning, with some reporting a very slight wobble at high speed (tell me if it’s your experience.)
It is interesting to know that Progressive Suspension, the leader in suspensions for all bikes of all types, recommends lowering your forks by 1″ (two if you are riding a Street Glide or have installed lowered rear shocks) to level the bike out. The cost is nominal ($129), the process is not labor intensive (about 30 minutes with basic tools and without having to change forks oil ) and their testing shows that your touring bike will handle better than stock.
