I see:

R100GS front fame/wheels/tank/forks?
Kick-starter gearbox
R80G/S subframe
Paralever
Rebuilt engine with all the Siebenrock goodies
R100GS soloseat/rack
Aftermarket full system
Relocated oil-cooler

What rear fender is that? Why did they omit the side panels?

There's this curve part of the frame neat the batt that does not look like it's from a R100GS.

An eye-catcher.

Cheers

For that kind of coin I'd build my own. I agree it looks wrong without side covers. I'd pass on a kick start. I don't care for the stretched gaiters and where's the side stand? I gotta have saddlebags so would need a different exhaust.

I like most everything else though, especially the paint.

Thats the 1070cc Enduro spec one. I'd like to see the other two they're offering.

Maybe they omitted the side covers because you can't fit the exhaust side cover with the Siebenrock exhaust? I suppose you could use side covers from a Mystic instead though.

I like the bike generally, though the price is just soo damn steep. I mean, I could throw that much (15k, minus the cost of my bike) at mine and have it done up 100% by HPN in style, complete with an R1150GS rear end, USD forks, motor work, etc.

For my money, I'd rather pilot an HPN rallyesport - course, waiting 2 or 3 years for delivery might be a problem.

Go down to the G/S builds. Been doing this for years. Sold these bikes all over the country.

http://gregsgssite.shutterfly.com/

The top model with all the upgrades goes for around $15,000..includes the suspension upgrades, dual plugged engine upgrades, 800 watt alternator upgrades, brake upgrades, new wire harnesses, custom paint, etc.

Just finished a motard special with special 17" wheels front and rear.

Just starting a retro G/S like the prototype with a dual shock rear.

I think that rear fender is one of these UFO universal fender. I put one on an old Honda and remember the light isn't DOT approved.

Probably without much of a warranty either. You gotta really want one of those.

Does anyone have any miles on Seibenrock's 1070 kits? I am curious as to how they do. It looks like they have their own fiber head gasket with a fire ring like the stock head gaskets? Although there is still BARELY any room for a fire ring between the cylinder wall and the cylinder stud holes or the push rod tube holes, for that matter, it has got to be an improvement over copper head gaskets I have been around that are used on some big bore kits. They often leak oil like mofo's! The big bore kits I have been around did make more power for a while until the super thin cylinder walls distorted badly and the piston rings could no longer seat. That pretty much turned them into an oil pump and reduced power back to lower than it could have been with a 94mm bore. The big bore kits I have been around had iron or steel liners. I would think that would be MORE stable than nikisil over aluminum as far as cylinder distortion is concerned but I don't know from experience.

Yes, very nicely done.

The sub-frame looks like a shortened R80/100 GS subframe to me.

I'm guessing that they removed the sidecovers because they're plastic bits o' crap that add no function to the bike. Kinda like the number plate that they left on (IMHO).

Interesting that they removed the tool tray and tool kit too. As for the curved part of the frame, do you mean the handle for lifting it onto the centerstand?

I also like that they ditched the crash bars and silly stock sidestand.

The photo posted by the OP shows the Siebenrock bike with what appeared to be a proper sidestand so they may have added that later.

Ok so at the most current exchange rate it's 14,000 usd to buy one of these
Plus shipping and import hassle if it wasn't based on a US spec bike.

That's not supercrazy for some folks and if you were to have a GS or G/S rebuilt by someone here in the states I'm sure you would get close to that figure. If not surpass it.

I'm glad that there's enough intrest in the marque that people are willing to build the bike, and buy them.

But boy, I think for that kind of cash, there's some real desirable bikes out there. Especially in this used market.

No, there's the vertical spar of the main frame from the seat down to the peg; looks more curved than the usual frame, I could be wrong.

This is the American Gulf Oil paint scheme?

The original 1050 kits from CC Products suffered from the thin wall syndrome you described..later versions had a sleeve so the heat wouldn't distort the cylinder and the piston lasted a lot longer.

The 1070 kit is a work of art..cast with enough clearance and the piston could be in an art museum..and it WORKS reliably. With the cam, it will make an honest 80 hp. Put that in a 400lb G/S frame and have a blast.
