I have a 2014 yz 450 and I'm looking to get the 2015 motor mounts. I have read they help with handling and rigidity.
Are they really that noticeable?
Where can I buy them?


Input and pictures is appreciated

Yes they are noticeable. I have 2 bikes setup the same and switched mine at the track so I could see for myself the difference. Any yamaha shop can get them.
I will also throw this out there. Have you played with different sag settings, fork height, adjusted your clickers? If not then I'm not sure you need the mounts.

I bought mine from rocky Mountain atv through the oem parts diagram for 20 buck's. I notice a little better handling in corners it let's the frame flex a little more.

I....THINK it was noticeable?  Seemed to be a little less dancy on choppy fast flat corners.  Such a miniscule change that an accidental 1psi difference in tire pressure could probably mask it.

Agreed.  I'm certainly not taking anything away from anyone, especially because I don't know them, but I'd be surprised if anyone short of a national-level rider could notice a difference that small.  I could be wrong, but very few would notice. 

 

Placebos can have significant impact, though.  If we feel that they help, and that helps our confidence, then great!  There's absolutely nothing wrong with that.  The mental game is super important in sports, especially in a sport like motocross where there is a big confidence factor and also some fear involved.

I DO notice the flexy front triangle on my RM250 vs. aluminum framed YZ's though.  That difference is very evident in berms that you really push the front end into.  There's a very pronounced "snap" back once it flexes that pulls the front end through hard.

 

It's also just super comfy.  Very hard to get arm pump from the super high frequency vibrations that normally get passed through the aluminum frames.

I'm probably not in tune enough to even feel that.  lol

I didn't think I was either, but it is really that noticeable on the steel framed RM.

 

The difference is nowhere near as drastic with the '15 motor mounts if that is any indication.

Thanks for the input guys! If there are only about 20 bucks I will get them and see for myself

Is it just the lowers that are different?  The uppers show the same part number for the '14 and '15.
