I aksed a question of all the WR riders about which would be best for a mix of woods and desert, a WR or a YZ (both would need some mods and armor obviously). Seeing as I really don't care about the e-starter (in fact I would prefer not to have the extra weight) they mostly all pointed me to the YZ. So, now my question of all the YZ riders. My local dealer has a new 05 YZ450 on his floor. I know that the aluminum frame came in the 06 models, but what other, if any, differences were there between the two model years? Is it worth the extra $$ to go with an 06 or even an 07 model? Also, did the 05 have a 5 speed tranny or a 4? And any of you who have ridden the WR and the YZ, how limiting is the close ratio tranny compared to the wide ratio? I used to have a YZ 426 and it worked well everywhere, but not sure about the new 450's Any advice would be appreciated!
