What to consider on used WR450F?

9 posts in this topic

I've just sold my reliable and trusty XR650R.Loved the engine but need something a bit smaller/lighter like the WR450F. What potential problems or issues should I be aware of when searching for a 2003-2005 WR450F?

I loved he rock solid rep of the XR650R. How does the WR450F compare?

What type of valves and adjustments does the WR450F take?

Any cheap tricks to make it more reliable, lighter and more power?

Yamaha is also super reliable

Get the newest one you can get. An 05 is good. I think that the forks changed in 05 and should be just a little better.

Valves rarely need adjusting on the Yamaha.

A little gas and some air in the tires is all it will need.

I have an 05 and it's been absolutely bullet proof. I ride alone a lot and totally trust this thing. For power of course the free mods are a must then gear down the counter sprocket to a 13 and add the GYT-R muffler and header and jet it correctly and hang on!!

03 had starter issues . do a search . or just stay away from 03 , basically it sheared the flywheel key .

i personally own a 03 and never had a problem with it , but it has the proper fix on it and did before i bought it .

newer the better .

I have always been a Honda man & also had the mighty XR650R but the CRF did not have the reliably I was looking for, but the Yammy wr did. I now have an 07 WR & havent looked back (Only to watch others follow lol) The reason also to move over to Blue that was a mate has a 04 Wr & had it since new , he has had no problems with it what so ever, After riding his bike I then new I had been struggling with an over weight bike.

You wont go far wrong with a WR.

I have had 400, 426 and 2 - 450's, the 03' woodruff key is the only issue that I have ever known of. All of my past WR's are still on the trail. I race and ride hard with all of them, frequent oil changes and other routine maintenance is all it takes... Yamaha 4T is the new "XR" in terms of reliability and longevity.

The only other negative I can think of is Yamaha's lack of proper lubrication during assembly, primarily swing arm / linkage bearings and steering head set. If you look at used bikes, just assume the swing arm bearings will need re-packing or replacing unless the seller tells you otherwise :thumbsup:

I wouldn't be afraid to buy an 03. It was a first year electric start. The flywheel key on a few bikes were shearing because there was no torque limiter in the new starter mechanism. The 04 and beyond has one. If you buy an 03 without the upgrade, it will only cost about $250 for the parts to upgrade. Not much labor involved to install them.

Plenty of info here at TT about the mod.
