Ok so I saw the 05 pics of the 250F on RacerX: Here is my guess on the changes on the 05 450F 1. finally correctly routed front brakeline - old news 2. larger shock resevoir - good news 3. Same Frame no changes - NO Alum frame! good or bad news, depends how you see it 4. possible rear linkage changes - good news will turn better. 5. probably better waterpump impeller - better cooling 6. Same style graphics - 7. No visual changes to the fork - maybe other internal changes 8. no visual motor changes 9. I hope there is more than this coming for 05.
