Durbahn is another that does the SBK 2V mix and superlight weight. BUT his site is offline. hope that doesn't mean anything bad.

edit: sorry stand corrected. it's a 4v 1098 and it's 305lbs WITH fuel

Does it explain the weight loss in there, and what they removed/added to get there?

I did. I don't see where all the weight savings came from.

V3-the Weight.

August 28/2008.

- incl. 2.5 Liters of Fuel    ( 2.5 x 0.74kg = 1.8 kg)
- fairing missing  ( Fairing is approx ~ 1.8 kg )

on the Scales ( inaccurate Bathroom Scales... the Bike might be a little more or a little less)
Front wheel 71.5 kg   -  158 lbs
Rear Wheel 64.5 kg    -  142 lbs

Total : 136 kg  , that's  300.22 lbs

When I calculated the weights of the Components for my rebuild in Winter 2007 and the weight savings I could "add" ( vs. my 999V2 ) and including the big open Q , which was the Frame weight ( I estimated the 1098 Frame weight 3.5 kg less than 999 ) I said to my buddies ( and maybe I've written it down here in this Web somewhere ) 136 kg is possible, including Engine Starter, Water and Oil, but without Fuel.


--------------------------------------------------------------------------------

Weights.

Ducati 1098 OEM : 196 kg including 15 Liters of Fuel.
15x 0.74 = 11.1 kg
196 -11,1 kg is 184.9 kg ( 408.16 lbs)

So 408 lbs is the wet weight of the OEM Ducati , without fuel.

So how to shave 108 lbs out of a OEM 1098 ?

It's not a secret, no mystery.

Check the rebuild Sections from 2007 on until today.

A 1098 Semi-Hardcore rebuild weight Calculation:

Lets say I'd re-rebuild my V3 back to a level where it would have more Identity with a OEM 1098.
Of course each measurement would add weight, lets start.

- back to OEM SSSW Setup                                               + 2.8 kg
- back to OEM Alternator + Rectifier + Alternator-Cover          + 3.5 kg
- back to OEM Clutch ( or dry-slipper )                                 + 1.9 kg
- back to all OEM screws/Bolts/axles                                    + 3.8 kg
- back to normal Ti-Exhaust ( Acra or similar)                         + 2.2 kg
- back to OEM Tail with Subframe                                        + 6.1 kg
- back to std. Fueltank/Airbox/Air runner Setup                      + 7.3 kg
- back to OEM Battery                                                       + 2.0 kg
- back to OEM Brakediscs                                                   + 1.5 kg
- back to Ohlins Shock                                                       + 0.5 kg
------------------------------------------------------------------------
That's                                                                               31.6 kg  or  70 lbs

So we'd have then a 1098 with :

Real light Fork ( each Fork leg should not be more than 3.2 kg)
Ti-Exhaust
Light fairing, as mine
Mag or Carbon Wheels
Light Callipers ( Brembo GP Calipers which are~ 680 gr each )
Light Triple Clamps ( ~1550 gr )
No lights

The usual track rebuild. Such a 1098 should end up at 167 kg without Fuel.

Durbhan's work is really good...  I have some of his Honda stuff in my shop right now!

I'm doing a lot of research on a lightweight bike..

Kamena did a 2v sbk chassis bike like I'm looking to build...

with no Ti frame
no ti spring
2 rotors that are NOT CMC
no carbon wheels

302 lbs.

And it isn't costing anywhere near 140k  

i recently started digging through the their site and some very amazing products. lower mounted fuel cell, aluminum axles, subframes, bodywork. all very nice stuff especially the 2v sbk bike.

Hopefully my monster will be around 330 wet. Thats with no fancy wheels or any superlight parts.

That is also on a tight budget, and by tight I mean 1k for everything.

Now my bike wont make much more power than stock, but that comes later.

Magnesium wheels...carbon fiber wheels...not much difference in $$.

That bike is very cool!! 

[Speeddog]
