Does one exist? I'm looking for a full structural replacement for the stock unit.

Doubt it. Would need to get something custom made. Hope you have $$$ in the multiple thousands to spend on it. Weight bearing/structural carbon fibre is MUCH more expensive than say a sprocket cover or tank panel.

If you want just the visual aspects of a CF subframe: http://www.bellissimoto.com/Monster696Carbon.html (http://www.bellissimoto.com/Monster696Carbon.html)

YES, one does exist.

They have been tested and proven, and drop roughly 60% of the weight, while looking insanely sexy.

We are just waiting on pricing, but that should be released soon.

They are produced by RAM Italia (with help from BST), and they will have Carbon Fiber Rearsets soon also.

:)

I'll keep everyone posted as things continue to progress.

How prudent of you to jump in.    ;D

Pics?

I've got official pics, but I've been sworn to secrecy. (sorry!)

Trust me, as soon as RAM Italia gives me the word, I'll let you know immediately.

til then -  [drink]

someone had posted pics on another thread that I had mistakenly thought were just covers.

BUT, I don't remember which thread.

 Shit!....This thread is getting me pumped up!

   I can only imagine the overflowing of carbon fiber, light weight goodness  [evil] of an 696-1100 monster.

Woah!

Bingo.

I still can't post my pics yet, but trust me, these things are sweeet in person (amazing that they can look better than they already do in the pics isn't it? ).    [bacon]

When will you be able to tell us how much $$? What is the weight of the stock subframe (ie, how many pounds does this remove)?

1. A LOT of $$$
2. A LOT of lbs
 ;D

The subframe is a lot lighter than people think. Not that the CF will not save weight.
but people forget it's an AL subframe already. the only steel is the one cross piece and the tail plate both of which are thin sheet metal stampings.

those people with money to burn, sure this is great. but if it's about the same price of say BST CF wheels, you'll get more bang for your buck with the wheels.

NOW, if you could afford both...

I would estimate that you probably save 1/4 of the weight of an equivalent aluminium piece, depending on construction. Aluminium isn't really all that heavy, after all.

I agree, in fact it'd have to be about 5x cheaper to be worth it compared to the price of BST wheels, as you'll feel the effect of unsprung weight reductions 5x more than sprung weight reductions. Not to mention the improvement in overall handling due to better suspension functionality with less unsprung weight.

But, regarding the weight of the original aluminum, those subframe bars are beefy and cast. Even a trellis aluminum subframe would save over the stock parts...

Ding ding ding!!!! We have a winner!!!! [cheeky]

have you had them off in your hands? not that beefy, but true a trellis AL would be lighter. but remember the suspension point is on the left subframe, so there needs to be a bit of serious strength to that area.

I'm dig'n that red carbon. That's cool - never seen that before.  [thumbsup]

It is most likely a red tint added to the clear. That's How I used to make red carbon parts.

i'd be a bit worried about using cf on a subframe like that... would be kinda worried about it cracking under stress after long term use...

i think it looks sick, but the hole in my pocket would make me sicker.

anyways, ill keep posted.

anyone making a trellis version?

It all comes down to the builder and designer. Considering how long people have been riding carbon fibre bicycles, I wouldn't worry; especially since CF bikes take so much more stress than a subframe.

I'm hoping for a price of under $1,000 on the subframe, they weigh 60% + less than the oem aluminum, and they are more than strong enough.

 [beer]

those numbers are encouraging.

one more question. are they based on the 796,1100evo or 696 frame. they are all different.

Tsk Raux.... dont go telling him that  [roll]

$1000 ???.  Way too bloody expensive!  [cheeky]  ;).

Are they? Interesting. In a major way or just the grab handles?? 




Oh and BTW Randy.... thanks for getting those Barracuda turn-signals out to me  [thumbsup].

how is the 796 diff from 1100?

I could see it being 60% lighter if the stock subframe was cast or forged, rather than tubular. It seemed like when I built carbon fibre bicycle frames, they ended up weighing about the same as a steel frame; however, the shapes I made would weigh about 10X as much if made out of steel (if it could be shaped like that). I used CF for it's ability to be made into frankly weird shapes that would weigh upwards of 25 lbs in steel; my frames would weigh 4-5 lbs when made in a swoopy shape. A tubular CF frame I built was less than 3 lbs; a comparable steel frame would weigh between 4 and 5 pounds.

I guess I am thinking still in terms of bicycles rather than motorcycles when it comes construction in aluminium. There simply aren't cast or forged aluminium frames on bicycles; they would be unacceptably heavy.

$1K isn't a bad price if it's 60% lighter and just as stiff as the stock piece.

I haven't seen the evo frame, but not sure where the new rear sets for passengers mount.

the old 696 and 796 are at least different in the rear tip area.

can you explain how? havent noticed

you can't mount the rear handles on the 696 frame.

meh...

just pointing out at least one difference that i know of

i was just saying, meh, not much of a difference. thought maybe more

that's the only one i confirmed.
also, the new evo has the passenger pegs hanging off the subframe as do the S&P that I have, so that's another stressor probably not factored into the pieces.

No, they did consider, and provide for the passenger rearsets that now hang off the subframe, but I was a little off on the price... They didn't mean "Under $1000.00 per subframe", they meant "Under $1,000 per side (each subframe is made up of a left, and a right half".

The amazing thing is that these will still be considerably cheaper than oem.

Expect more information later today/tomorrow.

Ouch.

Called it...

That sucks, for $1k I would have at least considered it, after all, don't go out to eat with the gf twice a month for 5 months and you're pretty much there. At $2k their market is going to be the high-end people. I'm sure they know this and have priced it relative to the cost/complexity of the manufacturing and the volume that they have an interest in selling/producing. I'm in product development too and know typically these decisions are made for a reason. sucks for us average guys though :(

I will say this, it's gonna cost a pretty penny for those who don't do a self install as well.

Ouch x 2
I guess I need to find some sponsors.

Ok guys!

I was able to beat the price down a bit, and retail for the pair of Carbon Fiber Subframes will be only $1699.95!!

These drop over 60% lighter than oem, and can be seen below:

They will be arriving in Mid - Late April.

We are accepting Pre-Orders here - http://bellissimoto.com/RAMSubframes.html (http://bellissimoto.com/RAMSubframes.html)

That just might be a possibillity for me, but it'll be the last thing I get after I've gotten every other possible mod out of the way. They look amazing, can't wait to get to the point when i can actualy justify buying them.

Just wait until you see them installed on an actual bike (preferably in person) and boom, you've just justified your next purchase.  [beer]

$270/lb give or take.  It's a hefty tag, but damn they're gorgeous

how does $270/lb translate into a HP mod

so let's say this drops what 2.74 kg

ok so the bike is 155 dry and the new evo has an even 100 hp (yes we know factory specs)
but that's
100/155
or
1.55kg/hp
so this mod is equal to about 1.8 hp gain in power to weight (albeit in a good location because it removes that from the high rear area)


so how much would a 1.8hp gain cost you in motor parts or work? you probably would have to adjust the suspension (maybe lower the front) to get the same shift in handling though (so add that cost of adjustment in)

That's an interesting take on it, and I like the figures you came up with, but lets not forget the visual benefits of the cf subframe (as you can't see visual changes from internal motor work).

Also, if your really looking to drop a lot of weight, get the Magnesium swingarm to go with it.

You'll see a significant reduction of unsprung weight, which is worth a lot more than any sprung weight reduction.

I don't think I expressed it fully.  1600 is a hefty tag.  270 / lb is actually pretty good considering how much ti nuts/bolts cost, compared to the ounces they shave.

dont' get me wrong. for a no holds barred build, these would be essential

CF subframe
Mag swingarm
BST CF rims
TI bolts everywhere
CF bodywork
CF Solo seat
AL or TI rearsets
AL Kickstand
TI axles
CMC Brakes
Monoblock brakes
Tons of motor work
CF and TI exhaust
I mean it could get insanely light
