The "Drop-In" lowering kits by Progressive Suspension make installation a 30 minute cake walk. Pull two inches out of the front end of your bike without the hassle of disassembling the forks or even changing out the oil and the whole process can be done with basic tools! You only have to lift the front end of the bike and - after removing the fork tube plugs - replace the stock fork springs with your new Progressive Suspension "Drop-In" springs. The longer stiffer one will control cushioning, the shorter softer one will lower the bike and control rebound simultaneously.
