2005 crank bearings

[atvmxr]

I just picked up a basically brand new 2005 450r with less than 5 hours use. I was looking around for forums and came across one talking about the crank bearings failing on motors with as little as 5-10 hours... stated honda had an updated bearing/collar/ larger OD seal as a fix.

Is it a given that the stock 2005 bearings are going to fail prematurely and I should go ahead with this update before I do any damage? From the paperwork I have the quad was purchased in March of 2005.


:confused:

I hope to be offering ceramic cranks bearings for 04/05 and 06+ 450R's within 60 days....


Ceramics are lighter and twice the strength as OEM steel radial bearings...

Until then, I would suggest you consider the HONDA crankshaft update retro kit...

Good luck.

yea they went out on mine, but it had some hard miles on it

Just keep an eye on shavings in your oil. i've seen some go out in a short time and some g o a couple years. But every 04 or 05 i've been around the crank bearing has gone out.
