I think even a tracker needs the front end quickened from the stock cruiser, soft as butter front end.
Understood - but if you are doing a "tracker" (as opposed to a "cafe racer") you would want to work toward a more upright seating position (e.g., higher/flatter handlebars - I'm planning on using ones from a KLR650; higher/flatter seat) with as much suspension travel (for rougher roads) as possible. Lowering the front suspension and using clip-ons will reduce suspension travel and create a more "crouched" riding position.
