Carbon Fiber 796/1100 Subframe?

[Raux]

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
