I have a 2017 CRF450r and we all know one of the biggest disadvantages with this bike especially on a hard pack track is the incredibly stiff frame. I haven’t seen one person complain about buying FCP or WCL motor mounts but are they really worth $400? Couldn’t I just drill my stock mounts for free or are the titanium fronts really that much better? Just an honest question. If they really make the bike that much more comfortable I’m willing to try them.

The problem with drilling the factory mounts is that here is a chance they can crack because they are cast.

If you can afford WCL mounts, I'd say "Yes" try them. To me, I felt a big change on just using uppers, then tried uppers and lowers. All for the better IMO.

Opinions from riders who have tried them seem mostly positive. Opinions from riders who haven't tried them, seem to be against them. Here's a long thread about engine mounts.

That’s true, cool thanks. I’ve seen that thread I just started this one to see if anyone has tried them on the 2017 specifically which seems to be the worst as far as rigidity and stiffness goes on the current Honda’s. I know another member on here got the FCP Soft uppers on his when they first came out and he was stoked. It’s just a lot of money.

I don't know the whole story but michaels partner left fcp and he designed them. Then they started wcl. I would support workschasislab personally.

Worth $400? No. Worth testing options, Yes. I've ridden WorksChassisLab medium uppers, OE 17', 17' drilled (5mm in center), and OE 18' mounts on a dialed 2017 test scoot. Haven't tried the lower mount, but would if the opportunity arose. Of all these options, the WCL were the best. Stock 18's with casting removed and thinned down a touch more after initial test were second. Drilled 17' in third and OE 17' as most rigid.

Have you backed off the torque 10% on every engine mount/hanger and swingarm pivot already? This alone helps quite a bit and should be done before changing any mounts as the "reset" can be a positive update; some from the factory have been over-torqued or a bit stiff without grease on the thru-bolts. Taking out the rear tank bolts is minor, but a plus as well. Can also "thin out" the front engine bolt (#19 on frame schematic) on a lathe if you're creative...

$180 for WCL uppers isn't too bad, considering just OE 18's are about $82 for the pair. $305 for the WCL combo is more tempting. Would never pay $400 for the FCP upper/lower combo, however.

Good info, I actually did go down about two foot pounds on each upper motor mount bolt and surprisingly noticed a little bit of difference. I already did the two tank motor mount bolts and didn’t notice that. Yeah I guess just buying the uppers from WCL when they are back in stock would be the way to go. Would the soft ones be too soft for moto? On the site it says they’re for off-road.

Wow, the works chassis lab mount pair is 304 vs 400 for FCP. I’ll definitely be going with ML512’s company if I get them. Would medium for both mounts be good for hard pack moto?

Vitalmx10 is another 10% off WCL

Hell yeah thanks DB. Your KX build was badass by the way. Probably a much better frame than the Honda’s! Hopefully these motor mounts help.

That looks good, did it make a big difference?

Michael responded to me via email and said the medium uppers and lowers should be good for what I do, now time to save up for them! Lol

If you recycle 6,000 beer cans, you can get them for free.

I’m coming off a broken arm and terrible at feeling things to begin with. I feel like it did make a difference.
