Anyone have a price on the Pierobon frames?

[Monsterlover]

Those frames are aluminum.  Which is cool, but 366 pounds isn't that good.

Since things *just* got put into perspective for me (I thought those bikes were lighter than that) I can't see spending tons of money of one of those bikes/frames to get down to 366 pounds powered by a 900 engine (or what looks like one- will have to ooogle the pic a little more)  <edit> I see it's a 1kDS </edit>

My 750ss that I turned into a 900ss weighs 354 pounds wet, meaning with fuel and oil, and Im using a stock frame.

I have plans to build a Ti frame and rebuild the exhaust system.  After adding CF or forged alum wheels I project the bike could get down very close to 300 pounds.

With a 900 engine.

Try to imagine that.

Travman. Anymore pics of this Pierobon?

I just pulled that picture off of their website.  I'm pretty sure that was the only picture of that particular bike.

Arc Fab's Ti frames were 18.5 lbs lighter than the stock Monster frame according to the email Doug Cook sent to REDUC:

Lets see, weight savings; A stock frame is about 30lbs, a Titanium frame for the single side swingarm suspension about 11.5lbs. About 1 lb more than the catilever style RatBike. Requires more structure to support the rocker link for the rear suspension. 

This is probably the most weight savings anyone will be able to get out of the frame.  All the other weight saving must come from other parts like wheels, exhaust, battery, etc.  When the Arc Fab website was still operating I believe they claimed one of their rat bikes weighed 300 lbs.  This bike probably had CF wheels and all of the lightest pieces.  Also, this weight could have been measured fluids or this could have been wet with all fluids.  I don't know.

Monsterlover, that's what I'm going for too. I'm bumping up my 620, (the one in my avatar) to a 900. It currently weighs 350lbs. I'm fabbing an aluminum subframe, and getting race wheels (not sure what yet). I would like to hit 320lbs. before next season.

And I agree about that bike pictured...that isn't worth it for 366lbs. The aluminum frame is nice but the price would probably make it rediculous.

Doug also made swingarms from titanium and from aluminium.  I have pics of an Alu swingarm he did, the whole things is from a single billet.  A joy to behold.

I have a stainless exhaust he did for a Pantah, the only one he made for that bike that I know of.  I might photograph it and post, the welds are stunning.

full billet swingarms are amazing. here's a BCM example:

that's the same pic i have, i am pretty sure that is Doug's work.  bear in mind Doug was working out of BCM's shop for a long time.

Don't forget the 900 will weigh more than the 620.

By how much Im not sure, but it's got bigger cylinders and an extra gear in the trans (right?)

The alum sub frame will help.  You could take it a step further and use Ti rod and spherical rod ends (to make it easy and save a few bucks) to further cut weight.

On the other hand if you wreck it just right, that subframe is a write off

Keep spares

What's the weight on that?  It almost looks heavier than a stock S swingarm

[fasterblkduc]

Pretty sure I remember that the weight on that was heavier than a stock aluminum swinger....and uglier (my opinion)

Yeah, I plan to make two at least. I'll stick with aluminum. That will be enough weight savings. IIRC, Taftonomous? put the materials together and cut off a stock subframe and he estimated 13lbs. lost. I will lose even more due to a very heavy superbike tail that I have on it now. (long explanation made shorter = I should save another 3-4 lbs)

[TAftonomos]

Peirbon frame and swinger = $4200 before shipping (that was ~2 years ago when I checked)  Way more now with the exchange rate.  Exactly why I didn't proceed with getting one.
