I'm considering a used WR450 and would like to know if there are manufacture years I should stay away from or are the bikes the same from say, 2005-2011?. Is there a year Yamaha made improvements that would be preferable to have? How do I determine usage, is there an hour meter or odometer? Thanks, Jeff

All the ones 05 and up in Canada have odometer, speedo etc.

All of the wr450's are good. all of them from 03 and up are worth having.

I guess you could try to get the aluminum framed ones (07 and up) if you can. But I have an 05 and haven't felt the desire to change mine. It goes anywhere I want more reliablly than that the other bikes in my garage.

determinine miles is hard to do. Look for wear around the areas where the boots go or where the frame would have come into contact with rocks and roots. Check the swing arm. you can see wear there.

But to be honest with you, the motor will last so long that you'll get bore with it long before it stops running on you.

first year of electric start is a bad year, but it's easy to fix them and you can tell if they are fixed without opening up the engine

This is true. 2003 is the first year of the WR 450. There were issues with the E-start but was easily fixed with the updated '04 parts. This is really the only year that comes to mind when looking for a WR 450. California riders need to be aware that '03 & '04 WR's were RED sticker which is a deal breaker for some.

if the starter side cover is flat it's the original part with no clutch

if it's rounded it shoudl be the upgraded parts with a clutch to prevent breakage and flywheel key sheering

Are you talking about the grey plate just above the front sprocket? Mine is pretty flat but with a slight curve.

sounds like you have the original gear

the upgraded part with the built in clutch is longer and requires a taller cover like this one
