15 motor mounts on a 14

16 posts in this topic

Anyone happy with the 15 mounts? Just installed them on my 14 and would say the thick aluminum is better than the thin steal ones on the 15. Had to do it but, not sure if it was any better! Will see if these break!

I did. Local dealer, North County Yamaha , had the mounts and shorter bolt in stock. $20 for everything. Took 5" to remove old, clean it up, install and torque 43 ft-lbs and 25 ft-lbs for the 2 smaller bolts. I didnt think i would be saying this, but the bike turns more accurately, predictably and consistently; you can hit the same line every time and it will hold it.....Crazy! Another buddy of mine who went with 20mm triple clamps and longer rear link did not notice anything, which makes sense. Id rather spend $20 & 5" for the same results VS $500ish & 1 hour for the same great result!

I tried a bunch of online retailers and the local dealers, no luck finding the parts...

'15 mounts are steel and thinner allowing more chassis flex

I ordered the parts from RMATV and had them 9 days laters. I haven't had a chance to try the bike with them yet.

That was my plan, they are showing out of stock till the end of the month though.   Ordered some from a dealer in MN this afternoon, they said they could get them quick...

Motor mounts came today.

 

Did a moto with stock mounts, changed to '15 mounts and did another moto.

 

WELL WORTH the measly $20!  Rode a '15 CRF450R, that was not worth $20...

 

Impressions:

-can feel the effects of the increased frame flex

-tracking entering corners has been improved

-less harsh feeling when bumps are hit during a lean

-hold lines through corners better

While I believe your impressions, it would be interesting to run truly blind tests on mods like this, where you don't know what the difference is from one to the next, and you're only being asked to judge which ride handles better.  The "Magic Feather" effect is an unfortunately powerful influence on most of us.

 

I remember when the '06 came out, all of the different T-clamp offsets that were made available.  Stock is 25mm, and people were trying stuff down to around 17.  Doug Dubach, who has an uncanny knack for test riding and analyzing handling, chose 24mm as his optimum.  Because it was such a small change from stock. nobody paid much attention until Applied Racing conducted blind tests with a diverse group of racers, and the group selected the 24mm offset, too, without knowing what the numbers were.  The same group selected a 27mm offset for the YZ250F, just to show you the unconventional results blind tests can produce.

 

But the effect of the mounts does show how small and seemingly insignificant changes can affect the overall feel of the chassis.

I understand your doubts. I'm not claiming that these were huge differences, just slight effects. I am one of those picky riders that can have someone blindly change a clicker and tell them what they did and how far, so I tend to notice small changes.

Is this in reference to the lower front motor mounts? 2015 change in upper mounts as well?
