....... no ....... i'd be tempted to put $ on the line that sez the MoCo has a 110 in a special line of 110th anniversary bikes.

The larger the displacement, the more heat the motor generates........as confirmed by the many comments on this forum about the heat issues with the later model Harleys due to EPA regs. I don't think I would want a 120" motor coming from HD on a new model bike.

Question(s): How large could a H-D production motor be in the 45 degree, long stroke, air cooled format?
Do you think a motor that size would have the reliability using the present m/f con rod system, and a multi-piece crank?
Do you think H-D would have the manufacturing quality control to build bigger motors?

The 883 also helps with the MoCo's overall CO2 emissions score. Auto makers (in Europe at least) are billed/fined by the government according to either how much Carbon their entire lineup emits or Fuel they consume. Having the 883 in the lineup reduces those numbers for the company as a whole. It's a bit like Aston Martin having the ridiculous Cygnet in the product line. They don't seriously expect anyone to buy it (why would you buy a rebadged Toyota iQ for Ł40,000?) but it helps their standing with the Government.
Also, the 883 is very popular outside the US.

Eventually the Moco will go smaller, and liquid cooled. There will be a huge outcry from the HD traditionalists, but the EPA will demand it. We will soon realize that the smaller, more efficient engine design puts out more HP and torque, and that is is a damn fun engine. Then we will wonder why the Moco was so slow to get there.
Why is it that giant displacement v-twin cylinders are so popular anyway?

Obviously there's more to it than that though. It's like directly comparing the speed of the processor in a computer. Doesn't tell anything like the whole story, but it's a convenient number to glom on to.

Now that the 103 has taken over as the main engine for the Harley lineup, making all before it obsolete or old school, where does Harley go from here?
My thought is that they should do away with the 883 engine keeping the 1200 in the sportster line. They have the 110 which is avalable in the CVO's, but could make it available in the rest of the Softtail, Dyna and touring bike line as an option. Is my thinking way off base on this?

I say keep the smaller engines.

Ran 80" 5 speeds for decades, did not think too much of twinkies. Everything I needed or thought i needed - the 80" 5 speed did just fine.
Run a 103" , 6 speed 11 SG now. I will catch flack for this but I'll say it anyway. this thing just plan ****ing rocks! The acceleration, the gearing and the overall way the bike just runs down the road simply just works.
I run the bike 100% stock, except for a taller windshield, some highway pegs, an IPod and a set of RJS orginals heat shields. I ride in the northeast and I'm sure it would be different if I lived out west or down south, but I do not have a heat issue from the heads or the cat, I can and have sat in traffic multiple times and the heat shields take care of business and the bike does not go into heat managment control, etc.
I'll take the roll on performance of the 103 over the smaller engines any day. Just came back from a 3 day ride fron NJ, PA, Maryland and the last day was a race against the storms on 81 to 78 and the new drivetrain is much better than the older 5 speed drivetrain.
