'99 WR vs '99 YZ - Radiator differences

16 posts in this topic

Anybody know what the differences are between the left side radiator on a '99 WR (PN 5BF-1240A-00-00) vs a '99 YZ (PN 5BE-1240A-00-00? I can't see any obvious differences on the microfiche. HLSM website shows a $80 difference between the two - of course, the WR is the more expensive one.

I believe the WR had a bigger radiator than the YZ in '99. In 2000, the YZ got the upgrade to the bigger radiator.

Can anyone verify this?

I do not think there are any differences. the last eight numerics of the two part numbers are the same. The prefix part numbers of 5BF and 5BE are I bleieve model designations ie WR vs YZ but the part is identical--this is my belief? Anyone know for sure????

The '98-'99 WR rads have an extra core. The YZ426 rads had the same as the WR

but are a different fitting to the earlier models.

My '99 WR radiators are two pass cores ~ 1.25 inches thick face-face. Looks like each tube is ~ .75 inch thk

Can someone with a '99 YZ check their radiators to see if they match my WR?

Thanks,

brian

Not going to be able to make it to Stonyford this weekend - we're moving in to our new house. That and I haven't fixed the bikes since Moab.

Mike - those dimensions are from the undamaged, right side radiator. I'd have to use a CMM to measure the curvature of the left side rad :) Is Howard's bike a '99?

Ok, Ok, My brand new radiator on the non cap side (because I broke the old one) is 10 cooling rows wide they are on 1cm centers with an overal width of 11.5cm outside to outside. I didn't bother with the height figured they were the same. I seem to think I paid $211.00 for it from Yamie ha ha that was back in February. I have my old one, be happy to sell it to you cheap. It only leaks when you put fluid in it :D Does yours leak or is it just all bent up in the shape of a pretzel? If it doesn't leak put your shroud back on with some zip ties and LETS RIDE!!! You wouldn't let a little thing like a bent radiator stop you from catching some mud via Dunlop air mail oops... I meant throwing some mud... :D:)

Howard,

My radiator is 11 tubes wide x 2 tubes deep & is ~ 12.5cm wide......

Can't remember - is your bike a '98 or '99?

I'll throw mud at you at Thanksgiving :)

Brian, I've got an old slow 99 with a fresh mud tire, I guess the extra row of cooling is worth the $80 bucks :D Your hope'in there will be mud to catch, oops... I meant to throw...Thanksgiving :)

Mike, I heard the '02 KTMs are coming with training wheels for the inseam challenged. I guess the advantage of having short legs is that no one can accuse you of dabbing :)

I was kinda hoping that the '02 WR would have a crash bar around the radiators like the Honda Goldwings.

Brian,

I'll have to check that KTM out. Actually the bike I've been eyeing is a new model made by Fisher-Price...... :D . Standing flat-footed shouldn't be a problem. The only problem I can see is the all-plastic construction........ :) .
