TRADE IT!!!!!!!!! :D

05's are good just not the best. they are only 439cc but they can be nice bikes if taken care of and properly maintained. they have had some battery charging issues some havent. some ppl have crank bearing issues some havent. i think its all about taken care of one. i have a 06 and stock crank from factory still in mine (knock on wood) lol i keep my oil changed frequently tho. i wouldnt think twice about trading a 400 to a 450 esp a yamaha i love mine.
