Front brakes failure by lock-up on a new hd xr1200 owned by hd and lent to me for a demo-ride (or test). The main witness has stated in writing that he has checked and double-checked that the front wheel was still blocked by the front brakes even after the crash.
2008 harley davidson night rod special rear brake light switch is located 1/2" from the exhaust pipe. This switch gets hot and melts the switch allowing all the brake fluid to leak out and create a complete failure of the rear brake. This is a very dangerous situation.
Fuel gauge does not work. It hasn't worked since the day I bought the bike. There are more broken gauges than working ones on this model of bike. Harley throws random parts and never fixes the real problem.
I received first degree burns to my thighs. This engine is known to be a problem with being hot as I found out after I purchased the motorcycle. I was stuck in traffic, due to an auto accident. While moving at a slow speed or stopped this engine gets hundreds hotter than normal operation.
Real bad mis-fire with spitting and sputtering. Took to shop and was told that it has a cracked fuel line fitting. I read a forum and learned that this is a serious problem and there is no safety recall. This could potentially cause a death.
Harley davidson has known about the catastrophic failure of the fuel pump pressure regulators on its 08 models for many months due to a defective part. This particular vehicle had been in possession of its dealer since oct.
I feel the helmet laws for motorcycle riders is an infringment of my rights under the constitution of the united states.
