2009 HARLEY-DAVIDSON FXDB Tires Problems

I HAVE A 2009 HARLEY DAVIDSON ULTRA CLASSIC ELECTRA GLIDE. THIS MODEL ALONG WITH THE "TOURING" LINE OF HD MOTORCYLES ARE NEWLY REDESIGNED AND USES THE NEW DUNLOP 407F MOTORCYCLE TIRES. THESE TIRES ARE THE ONLY TIRES THAT ARE AVAILABLE FOR THIS LINE OF MOTORCYCLES. MY TIRES ARE "CUPPING" AFTER 7,000 MILES. THE CUPPING IS CAUSING VIBRATION AT HIGHWAY SPEEDS AND NOISES WHILE CORNERING. I HAVE BEEN READING ABOUT THIS ISSUE ON HARLEY DAVIDSON FORUMS AND I HAVE DISCOVERED THAT THERE ARE NUMEROUS COMPLAINTS ABOUT THIS ISSUE. THERE ARE REPORTS OF 407F TIRES CUPPING WITH JUST 1500 MILES OF USE. I FEEL THAT THE CUPPING PROBLEM OF THE DUNLOP 407F TIRES MAY LEAD TO A DANGEROUS SITUATION AND THAT THIS ISSUE HAS TO BE INVESTIGATED. *TR

2009 HARLEY DAVIDSON FLHX (STREETGLIDE) RIDES EXCESSIVELY HARD. IT SEEMS AS THOUGH THE REAR AIR SHOCKS ARE NOT WORKING. AIR PRESSURE HAS BEEN ADJUSTED FROM MINIMUM TO MAXIMUM PRESSURES WITH LITTLE TO NO CHANGE IN RIDE QUALITY. THE IMPLICATION IS...AT HIGHWAY SPEEDS EVEN HITTING A SMALL BUMP IN THE ROAD THE BIKE TENDS TO GO AIRBORN. THE SUSPENSION IS SO UNYIELDING IT'S CREATING A SAFETY HAZARD FOR THE RIDER AND PASSENGER. I TEST RODE A YAMAHA ALONG THE SAME ROUTE AS THE HARLEY . THE DIFFERENCE WAS REMARKABLE. THE YAHAMA ABSORBED THE BUMPS AND UNEVEN PAVEMENT EXTREMELY WELL. A 1000% DIFFERENCE IN RIDE QUALITY. HARLEY NEEDS TO RE EVALUATE THE 2009 FLHX. I HAD A 2008 FLHX AND IT DID NOT RIDE AT ALL LIKE THE NEW 2009 WITH A NEW RIDGID CHASSIS. ALSO THE FRONT TIRE IS CUPPING. HARLEY KNOWS ABOUT IT AND CHANGED THE TREAD PATTERN BY REVERSING...

DUNLOP D407 TIRE (FRONT) FOR THE HARLEY DAVIDSON 2009 FL TOURING MODELS INSTALLED ON MY2009 SCREAMING EGALE FLTRSE3 THE BOLD ANGLED LATERAL GROOVES EXHIBIT ABNORMAL WEAR AND UNEVEN TIRE TREAD CUPPING. VIBRATION DURING CORNERING AND LANE CHANGES, THE UNEVENLY WORN AREAS ARE NEARLY WORN TO THE BOTTOM OF THE LATERAL GROVES ON THE LEADING EDGE AND THE OTHER SIDE IS CUPPED. THE CENTER OF THE TREAD APPEARS TO BE NORMAL. THIS WAS FIRST NOTICED AND REPORTED TO A HARLEY DAVIDSON CALIFORNIA DEALER TWICE ONCE AT 3000 MILES AND 4100 MILES OF WEAR. NOW AT 5000 MILES THE VIBRATIONS PRESENT WHILE CHANGING DIRECTIONS OR CORNERING IS UNSAFE. *TR
