Hypermotard 796

[Triple J]

The heads sit on top of the pistons.   Why change the bore and stroke of the exiting 803 engine?  Why not simply update the heads?

Sand cast cases of the new motors? That process allows a lighter weight motor...so better to start with the newer design.

the dorsoduro is more like Hyper1100 competition... ithink it has a bit more horsepower....

Noted, but in general they're all competing for similar buyers.  They aren't the true "Supermoto" bikes like the SXV and the KTM SMC bikes.

They didn't that is the same bore/stroke combo as the 800.  The engine is a 696, same bore as the 800, with the 800 crank.

Ah ha! just what I suspected.  So it really is an 803 cc engine with the same bore & stroke (with the current minor updates applied to the 1100 & 696.)  This could be good in the future for current Monsters with the 800 engine.  If they can find a wrecked 796 Hyper they might use the heads from the newer engine for a few more ponies.

DS1000 & 1100 heads won't fit onto a 900 motor as well as 796/696 heads won't fit on the old generation small-case Ducati's (600, 620, 695, 750 & 800).

The old motors (900, 600, 620, 750, 695, 800) don't have cylinder head gaskets between the barrels & heads.  696/796/DS1*00 motors do.

That is why the heads won't swap between the old & new.

[Travman]

Thanks Duck-Stew for the clarification.  So how did the old motors make a seal between the barrels and heads if they didn't use a cylinder head gasket?

Only on the DMF would a thread about the newest announced Ducati immediately sidebar into a discussion of the cylinder head design of Ducati motors over the years

Machined aluminum bore in the head that receives the bore.  Just aluminum on aluminum.  NO gasket.

Thats what I thought you were going to say.  It doesn't sound right, but I guess it works. Were there ever any problems with the older design?  I guess you couldn't "blow a head gasket", but you could still have a leak.

It is sort of like the fact that there are no cam bearings in the latest air-cooled engines.  The cam simply rests in the heads.  It doesn't sound good for rebuild-ability, but I guess it works.

I have an 1100 Hyper and it is a really tall bike.  The 796 is only going to be an inch lower which won't attract buyers who want a "smaller" Hyper.  I don't know how much they will ask for this, but with non-adjustable forks and a wet clutch, it should be well under $10,000.  I just got my '09 for $10,400.

now look at what you can do to one

[DRKWNG]

I'm curious to see where this bike goes.  I could almost be in the market for a decent "town bike", but I almost feel the KTM is more my thing...

[superjohn]

I like the thought of a smaller, lighter Hyper. If I were in the market, I think I would prefer a 796S with the adjustable suspension from the 1100S than the base 1100.

Well maybe you'll almost make a choice...
