NHTSA Complaint #766320 — 2000 POLARIS EXPLORER

FRONT SPROCKET NUT REQUIRES TIGHENING EVERY 2,500 MILES PER POLARIS/VICTORY. THIS IS UNECCESSARY PERIODIC MAINTENANCE THAT SHOULD BE ADDRESSED BY AN ENGINEERING REDESIGN OF THE 5TH GEAR OUTPUT SHAFT FOR REVERSE THREADING (LEFT HAND THREADS) TO ALLOW FOR CONTINUAL TIGHTENING OF FRONT SPROCKET NUT DUE TO RIGHT HAND ROTATION INERTIA. THE PRIMARY ISSUE WITH THE TRANSMISSION IS DIFFICULTY SHIFTING FROM 2ND-TO-NEUTRAL-TO 1ST GEAR ONCE THE MOTORCYCLE IS BROUGHT TO A FULL STOP AT A LIGHT OR INTERSECTION. DRIVER IS FORCED TO PARTIALLY RELEASE THE CLUTCH TO FORCE THE SHIFTING.
