I have to say it is an ugly motor. I would hope they could produce something that doesn't look like a Jap motor. Hopefully this is just some pics of someone building their own version a Bullet twin.

I think it is interesting that all these years they had a verical case split with an open cradle, meaning you had to remove the engine to work inside the case halves, even though the bottom of the frame was open.
Now, on this one, they horizontally split the cases so you could remove the bottom to work on it, but they put it in a closed cradle frame, so it has to come out to work on it anyway.

That engine has a very Suzuki look about it: the ohc valve adjuster caps especially make me think that. I haven't done any looking but I'm tipping gs500 ?
If Enfield did a twin, would they go ohc or stick with pushrods?
Happy April fools day ( for yesterday here. We're living in the future,man )
Edit: nope not gs500

The rumor is that the factory has 5 twins being tested and refined.
It looks like a SOHC design without pushrods, probably with a slightly shorter stroke. Can't comment much on it now, but if they can make it as good as a 1990s UJM twin, then they have my money.

There is also rumour that there are two bikes codenamed the P1 and the D1

One is a 385cc scrambler sort of offroader to compete with the Hero Impulse, the other a regular 385cc "Bullet" with the same age old looks.

The rumors of horizontally split crankcases were floating from 2012.

That motor just looks so bland, UJM indeed! With the line of the CGT frame they could nicely throw in a few styling references to the Rickman-framed Mk2 Interceptor, perhaps a more prominent nod to the Mk2's timing cover without compromising on the internals. Lost opportunity in the making?

If they build a strong running twin, it won't get lost.

Yes, that motor looks unappetizing.  I think a new p-twin should look fresh, and classic at the same time.  The motor in photo does neither.

 I hope the lump in the pic is an engineering proof of concept unit.

 My bet is any production unit will be over built under stressed and have a bit more splash in the visuals department.

+1 It's a prototype, they're not going to waste money making something look good when they don't even know how it's going to run.

Prototype or not, not being the key word. Who in there right mind would buy an Enfield with that 70's looking Jap motor in it. C'mon, really, this has got to be a joke, right? This has got to be the decoy prototype.

The pics have also showed up on Hitchcock's forum.

I suppose by looking at it, that they retained the pushrod valve gear, since those adjustment port covers are up there. That also probably means that they didn't include the hydraulic tappets, and went back to solid lifters.
The cover really doesn't look tall enough for overhead cam.

All conjecture, but it is fun to speculate.

Whatever it is, ACE will be able to make it better
More REs mean more ways to fiddle with REs

I love the idea that they are finally doing a twin. It's a cool platform that has definite vintage ties to the old, in a certain way.

And it will be a lot of fun for me to tackle a project like this!

Just one more article to fan the fire with.

Royal Enfield people are good people

Ooh!  If the new alleged Himalayan scrambler is a 410cc overhead cam I may consider buying that instead of a DRZ.
