Interesting but I do not see anything that would address any sumping or oil migration issues. But I am definitely not an engine designer.

Doesn't seem to say much for Harleys confidence in the Milwaukee eight.

Somehow those two words do not belong in the same sentence. :-X

That's an entirely different top end. Single rocker. Won't make sounds we're used to. Cam chest will be very different to drive that too. Perhaps building toward next major iteration of EPA requirements.

I hope they do more than 1 million miles of virtual testing on it
And it holds up for the real world riding :drink:

This may be something that HD is developing for a small single cylinder sub 500cc motor. They have indicated that they are gonna release a new machine in this class for entry level and Asian markets. If this is part of some twin cylinder design it's gonna take at least 3 cams to drive the pushrods, one to drive the intakes, and one for each exhaust, assuming the induction system is located in the "V".

The link does not work for me.

Hmmmm,.....push rod driving a single rocker operating two valves. You know, I'd trust it more if the Japanese made it, but HD being HD, let's see what percentage of bikes make it to 50K without taking the heads off for something.

To say I'm curious/interested how HD would develop this in to a heavyweight bike's engine is an understatement. It would be a relatively complicated (by HD standards) design and the systems at least suggests something that would likely turn more R's than we're used to to find the power curve in Harley's big bikes. So color me interested. Like you I thought the small engine option was the more likely though.

Looks like they just using a "bridge" , diesel engines have used them for years.
