Are YFZ450/400ex hubs interchangable?

[Les Davis]

I want to use a spare set of beadlocks on my 400ex that are for my YFZ450. Can I mount the YFZ hubs on the 400ex axle? The axle is a Durablue X-33 axle. I'm worried that the splines arent the same on the axle and may damage it? Any help would be appreciated.

Why dont you just try and put the hub on and see if it fits? I seriously doubt it will though.

I thought the x-33s had special hubs but I could be wrong. I think you may have to order x-33 hubs in a yamaha pattern.

[400exrider707]

Good point I think the x-33's come with their own hubs

[Les Davis]

you are correct. I had to get new hubs with this axle. Gonna try the Yamaha hubs on there tonight. Hopefully they work!!!

I got the X-33 axle and I didn't have to get new hubs.

[Les Davis]

let me correct myself...I had to get new hubs cause the splines were shot when they were putting the rear end back together.

what about for the stock axle or an aftermarket one that uses stock spindles. i heard that it will work, and makes it 2 inches wider in the rear, but i don't kow for sure.

[Les Davis]

I checked the hubs compatibility. The hub slid on pretty easy as though they would fit but there was a little bit of front to back movement on the splines. I think there was enough movement that it would eventually destroy the splines over time.

[sampleez]

Ahhhhh that sucks. oh well, i guess i'll just have to save up for a RPM

[Les Davis]

yes it does. I was planning to swap tires/rims back and forth between bikes. Oh well, it was worth a shot.

get a big big washer

[Les Davis]

The movement was from front to back not side to side. It was minor but enough that it will most likely ruin the splines over time. You will definetly require a bigger washer or spacer if it were to work. There's a substantial difference in the hub dimensions (thickness). I think I measured 1/2" give or take a little. This will differ depending on the type of axle you have. Mine was a x-33 +2 style.
