Does anybody know if the Neken SFS triple clamps for the 14-15 YZ450's will work with the 12 and up WR450's?
I assume they would because the forks are almost the same I believe, but not sure about the geometry of the clamps and such. This would be an expensive mistake to make. Can anyone help me out? Thanks.

There are some issues with mounting your speedo and headlight on a lot of the aftermarket triples.
So even if they do bolt on beware they usually were meant for a number plate only.
I use aftermarket triples on the 07-11 and had to make quite a few brackets.

WP forks are larger in diameter on the top half

The upper openings would need to be shimmed for KYB forks.

Good info. Thanks for that. Fabbing up some brackets shouldn't be too hard.

That's what I was looking for. I'm trying to think of how I could shim it evenly around the forks. Any ideas? Also, any idea on the differences in geometry between YZ triples and WR?

My main concern with the geometry would be screwing up my steering or something by fitting up a triple not meant for my bike.

Then why do it?

Nekken Triples are very flexy compared to OEM YZ, too.

What is the point?

They make the SFS tripples for KYB forks also, not just WPs.

 

I would think that you could buy a pair for a 2010 YZ250F and make them work since the frames are essentially the same.

I broke my collar bone recently and since then it is sometimes painful to ride a regular bicycle, so I am interested in any type of damping I can take advantage of.

Do you know where I could find those? Their website is of no help and only lists triples for the brand new models.

I'm basing the info from an MXA issue where they convert a 2012 wr for moto. They claim that the triples are narrower than the yz by a few mm, but they were still the same offset (22 mm). But someone else on here claimed that the 2012+ we still had the older 25mm offset. Either way, you would still need the YZ bottom clamp to go with Neken top clamp,and then you still have the issue of mounting the lights and electrics. Anything is possible, I love modding bikes and making something my own

Ah yes. Me too, both shoulders are shot.

I use Flex bars and a good re-valve

I've been looking at the Flexx bars as well as the composite ones, but not sure which ones I would get yet. Also looking at sending my forks off to Race Tech and getting the right springs for my weight and a revalve. But I really wish I could find a way to make some Nekens work.

Surely this should be top of the to do list and then see where you are at

Highly likely to solve most problems

Personally, I would look into a set of used 2006 YZ forks (about $250 on ebay) before putting on that Nekken dealy.

Get the new forks and your shock re-valved and re sprung for your weight.

Use a 'real' suspension service like Factory Connection, MB-1, RG3, TBT, etc before using Race Tech.

Race tech is better than nothing, but not a 'personalized' tuning shop. They basically sell cookie-cutter kits; everyone gets the same tuning regadless of size and skill.

 

The difference between your stock '12 WR suspension and a YZ fork/WR shock re-do is like going from two flat tires to brand new Bridgestone X-series tires!

The '12+ WR suspension is essentially the same equipment that comes on the YZs with different valving and springs. Keep your suspension, get the right springs and a revalve as a starting point.

The frames of the '14+ YZ450F and the '12+ WR450F are not the same in any way.  Also, the standard offset for a WR is the old WR/YZ standard 25mm, while the OEM offset on the later YZ450 (from '10) is 22mm.

You can accurately measure the offset of a T clamp this way:

Oh dang, saw '12, thought '11.

One of my reasons for picking the WR was because the suspension is so capable from the factory for a rider like me, but I know you guys are right about springs and revalving. I'm not an A rider and buying full new suspension (new forks and shock)for my bike is not on the table.

I'd also have to agree with woods rider in that the new WR suspension is very similar to the new YZ stuff, and I can't imagine why forks from an 06 YZ would be any better than my stock ones after a revalve. Maybe they are better, and maybe it's a good idea for some people, I just think I don't need it. I'm not even sure I need a revalve in the shock, I actually like the way it performs, but the forks do leave something to be desired.

What I'll likely end up doing is swapping the springs on both ends and revalving the forks to start and see where I go from there.
