looks like has 2 guages so rev counter is back?
has v9 non locking gas cap?

Thanks for posting this intriguing news, Dogwalker!  Can't wait for EICMA to see if we'll actually get the 850 that most seem to want.

Am I to understand from the article that they've added the hemi heads to the 750cc engine?

Yeah. The article says the Stone and Special will have an hemi 750, and the Racer an 850 with higher performances than that of the V9.

Other sources tell than the 750 heron will be kept in production for the Stone, while both Special and Racer will have the 850 hemi.

Interesting.  If they develop a 750 Hemi head, how easy would that be to swap out for existing Herons?

It has to be seen what the charateristics of this 750 will be. IE if they'll keep the boreXstroke as it is, or will use the 850 bore with a shorter stroke.

How are you going to incorporate, or otherwise, the air injection? It would need more than the heads. Probably both airbox and maybe ECU/TB. I have no idea as yet how the air injection is controlled.

No idea, that's why I asked the question.

[pete roper]

So we're both in the dark!

As time goes on engine management is going to become more and more complicated. We'll have to cope with that. Having just spent some time around Milan and the Po valley I can fully understand the need and push to control all types of pollution. Euro 5? Bring it on!

Ok, but I still don't see a point. Larger displacement would probably mean slightly larger fuel consumption and weight gain with no obvious result. But yeah,I agree, we are moving forward.

Well, I'm a guy who is completely happy with my V7 which I've now had for approaching 4 years (this December will be the anniversary), but I see the point.

Reports are the new motor feels great and has a bit of kick in the pants.

It's supposedly just as efficient.

It's not really any heavier.

And the heads allow it to make stricter emissions standards.

I don't see the downside.

Pete, in The USA, end users usually remove air injection from their Triumph Bonnevilles, which have had it a long time.

For hotrodding purposes, a V7 owner who wanted the new heads (and possibly cylinders/pistons/rods) wouldn't use the air injection, since it's mainly for EPA emissions which aren't enforced at the consumer level in most of The USA.

I'm diggin the Ohlins shocks:

I'm diggin the rider's feet where they belong and a proper tank.

Where is the air added on the Bonneville? If to the pipe it is probably easy enough to disable. With the V9 it appears to be added to a chamber adjacent to the exhaust port on the valley side of the head. It looks too as if there may be some form of valve, possibly a reed, involved?

My feeling is that simply blanking it off might cause all sorts of odd harmonic problems with exhaust flow and it would have to have some input on the lambda interpretation. I'm not suggesting swapping the heads would be impossible, (Although as you note it would also necessitate most of the rest of the top end componentry as well.) simply that it is going to involve a lot more than simply physically changing the parts. My guess is that it would be cheaper to simply swap bikes.

Yeah.  When we're dealing with $8000 - $9000 bikes, several thou in engine work doesn't make a lot of sense!!!

[rboe]

Well if you're going to go there, a strong case could be made that owning and riding motorcycles don't make a lot of sense. 

[Zinfan]

The only thing I'd change on my 2013 Stone vs this bike are those Ohlins!

[Kev m]

Ya know I missed this first time through the head. That makes PERFECT SENSE and is exactly what people on this board have been saying for years. That the Racer should get a little more punch.

I'm sure the 883 Sportsters are quaking in their boots in fear of this new beast........

And pistons...it will need hemi head pistons
