On model years 2008-2010 of the CBR1000RR there is a acknowledged issue by Honda regarding the crankshaft and primary driven gear in the engine. These crankshafts were not properly produced causing deformity and emitting a whining noise. My motorcycle is one of the bikes that emit the crank noise. Honda did a 5 year warranty extension but that did not fix all instances of the issue as not all bikes produced the noise indicating an issue during that 5 year time frame. A deformity in the primary driven gear is arguably a large safety concern for motorcyclists with the affected motorcycles, as if the teeth on the gear fail, it could cause a catastrophic failure while moving, posing serious risk to the rider. There is a service bulletin that exists for this year and years 2008-2009 as well where Honda acknowledges the issue. How is such a large and potentially dangerous issue only considered warranty extension worthy? A vital component of the engine is incorrectly hardened which results in deformity. I have attempted to speak with Honda to get more information regarding the issue, but upon asking if it is still safe to ride the motorcycle, Honda would not make any further comments creating more concern for the safety of anyone riding one of the affected bikes.

ALSO, THE C-ABS LIGHT BEGINS TO FLASH CONVENIENTLY INFORMING ME AFTER THE FACT THAT I HAVE AN ABS MALFUNCTION. *TR
