Here is the dumb question of the day: Does anyone know if you can put the front forks or the rear suspension from a 2008 yz450f on a 2011? I looked at yamaha-motor.com and the part numbers on the outer fork tubes are very close. The reason for asking is that I have factory suspension work done on my current 08 and am looking to get a 2011. I'd rather avoid getting new suspension work if possible, I just had the suspension done. I also just blew up the bike and need to get a new bike. On a side note, I can get a new 2009 for $5000 and a new 2011 for $6600. If I get the 2011 I would need to do the suspension again making the total investment on a 2011 about $7400 for a total difference of $2400 between the two bikes. What seems like the better investment? Any opinions?
