Best for: Built for laid-back boulevard cruising and style-focused riding rather than outright performance or cornering agility.
Built for: A classic American custom cruiser with big V-twin torque, chrome styling, and a relaxed, thumping ride that prioritizes presence over speed.
Not ideal for: Not a good fit for riders wanting sharp handling, off-road capability, or a lightweight, flickable machine for tight cornering.

Risk: THESE SITUATIONS COULD CAUSE SERIOUS PERSONAL INJURY OR CREATE A FIRE HAZARD FOR PERSONS OR PROPERTY ON OR NEAR THE MOTORCYCLE.

Remedy: DEALERS WILL TEST EACH CANISTER FOR BLOCKAGE, THEN REPLACE AS NECESSARY. THE RECALL BEGAN NOVEMBER 4, 2004. OWNERS SHOULD CONTACT HARLEY-DAVIDSON AT 1-414-343-4056.
