I purchased a brand new CRF450X 07 Model in Jan 08. Since then, the thing has been back in the shop to get a valve adjustment done. 3mths later, it now is becoming hard to start again so back in it goes. The horn works when it wants to. The indicator lenses have fallen off and the LED indicators raent working as they have shaken apart. Now as well, the battery isnt charging. What a lemon. Got heaps of grunt when it goes well but when it dosent, it costs an arm and a leg to keep it on the road. Piece of junk !!!!!!!
