Chrome Moly subframe replacement

[NM]

We have designed a new Chrome Moly subframe replacement that moves the A arms on a forward angle of about 2.5 inches on top of the spindle, and about 3 inches on the bottom to improve caster angle and get rid of that nasty tipping point on the Nytro's. You still use the same shocks, A arms, and steering components and just replace the subframe.
It will look more like the Polaris Pro, where the A arms are angled forward.
They will be powder coated black, or can be done custom ordered in any color.

The fab shop is ready to go on this, and they have a ton of hours already invested in cad drawings and water jet programming, but I am getting cold feet on the minimum 10 orders to start the project. The selling price would be about 1600 - 1700 per subframe, so it is a huge investment upfront. The fact that it is stronger than stock, and will offer huge handling benefits should sell the product, but we wanted to get some feed back first.

Please let us know what you think!! Thanks in advance.

Sounds like what skinz has done with the new a-arms? Is this true? IMO the price needs to be about half and you will sell ALOT of them.

want to see a photo of the subframe my stock one is bent already. how many orders you got so far. will it work with the barkbuster a arms and spindles?

 

[ruffryder]

any weight savings? timbersled front end plus this might be a good option..

How much are the Skins arms? And your still stuck with the wimpy lightly painted stock subframe.

Should work with any aftermarket a arms that have stock geometry.

I have about 5 committed including 2 that will go on our own sleds.

There are none built yet.

Might be a few pounds lighter. The strength and handling benefits will be the selling features. The powdercoating will be a nice touch too.

The skinz kit is $950. Comes with Chromoly arms, with better geometry. I think it is likely very close to the geomotry your saying for your subframe.

Now the secret is out on whats makes the nytro handle better I would bet everyone and there brother will be producing a kit.

Also I was told by someone who has a very close business relationship with yamaha usa in wisconson that "you just wait and see". I took it as wait and see what yamaha has coming. . .

A kit from yamaha for 3 thousand? lol

I agree it seems like there are many players coming out with stuff now. I wonder if timbersled will have a response for this?

NM, do you have any pictures / models? I am curious as to how the stock plastics line up with the change in a-arm mounting location.

Does the subframe change the ski stance at all?

I beleive the guy who i was talking to was in fact refering to a all together different chassis, and something tells me a turbo will be involved.

Sorry didn't mean to side track the thread.

The subframe sounds like a great idea as it kills two birds with one stone.
1. Weak Subframe
2. Poor Geometry of front suspension making it hard to sidehill

Plastics will fit the same as OEM. There may be a couple very small gaps. It looks like the width will be about an inch narrower, which wouldn't hurt my feelings after riding my Pro.

I would like to see pictures. Thats alot of money for a subframe. you can buy 3 oem subframes for that price.

^This could... possibly... maybe... might... be a hot topic by this time next week.


Pricing on this subframe is in the ballpark,(Diamond S chromo sub is $1500+)... the ability to run stock or aftermarket A-arms, AND fix the stock geometry/strength issues makes this a very attractive option for sure.

The OEM subframes can be strengthened with my gusset kit. I've repaired and reinforced several frames and also have sold many kits to Nytro owners with no complaints. Because the weak OEM frames can be corrected fairly cheaply the new geometry would have to make a considerable difference in how the Nytro handles to justify that price. Without some additional proof of concept this might be a hard sell especially with other available options.

i think my back just gave out a little seeing welds that big on a sled...

I suppose it is enough money, but when you consider guys are laying down 1000 for a-arms and still have to buy different shocks to use them, this is not out of range.
Besides...you can't compare this to a stock subframe, so the money is not really relative. In Canada, retail on a subframe is 800.00, and one can be had for 6-650 or so plus tax.

This is good feedback though, and opinions are what I asked for. Thanks

 

[WyoBoy1000]

If it gave decent weight savings you couldn't make enough of them. If I had a yami I would be very interested, just for the handling aspect.

NM,

any possibility of doing a bolt on kit with maybe a little welding involved? Might allow for the price to be reduced as you won't need to be building the complicated subframe. Not sure if it could even be done, but it is a thought.

FYI, the subframe has nothing to do with ski mounting and locating..

That is a great suggestion, and we did talk about it. The biggest issue is that to turn the arms inward, the front bolt holes remain pretty much where they are (with new angles) and the rear mounts actually come away from the frame and angle forward. We can't really find a good way to change the angles of the front mounts, so we thought maybe just build a- arms that do the same thing...but I'm pretty sure someones already doing that.

Good idea though.

You could always include a fancy custom spindle for the same price as others.. I hate my fricken spindles..
