Diesel turbo Cruiser!

Must be a 'teaser', there are only stat's, no bike.

So if this thing goes into production, do we have to call harley's something other than tractors?

April issue of AMCN had a ride report by Alan Cathcart in Germany.

Don't worry, I'm sure the boys in marketing will soon develop a "soul" for it so that people can justify a purchase!

This is another of my pet peeves, being the marketing of consumer goods, ranging from hi-fi to clothes, cars and bikes that blinds people to the reasons why they should be making a particular choice. "Fashion" is a perfect example - why should you buy a particular product? "Because it's fashionable" is a bad answer - the fashion is defined (by advertising, marketing etc) by the person trying to sell you the product. Women probably support the economies of several S.E. Asian countries based purely on the requirement to have fashionable shoes that need to be replaced each season, let alone each year. Not to mention the clothing industry. Guy's don't escape. Cars, bikes, cameras, gadgets are all marketed on the insecurities or desires of the buying public. Anthropomorphising inanimate objects is another tool of the marketer, e.g. that is so sexy, or that v-twin cruiser is so masculine, or "don't buy that UJM, it has no soul".

Getting back to the subject at hand, it was an interesting solution to an engineering problem, although that problem was self-defined by the maker methinks - lets put a diesel into a motorbike! Diesel engines are generally a lot heavier than petrol, due to the higher stresses due to the compression ignition combustion (higher compression = more pressure/forces on the piston, rod, crank, cylinder etc) requiring more material to resist those stresses. So a diesel was never going to go into a sport bike - the sport-bike buying public would not stand for a lardy bike. The advantages of diesel - high torques, and the disadvantages (low rev limit due to heaver components, vibration due to ignition) meant that any use of a diesel engine in a motorbike was going to end up in a cruiser or standard-style bike (didn't the Indian Enfield have a diesel version as well?). The contra-rotating crank is another nifty thing - but again adds to the weight. It's a good way to adapt the advances in diesel engine technology that have occurred in the past 20 years to motorcycling.

Is that a detroit diesal like design but instead of a supercharger there is a turbo. If so how did they compensate for the turbo build up period(lag).
Or am i wrong and its jus pure conicidence that the turbo looks like its going in the crank case(lik a 2smoker) and theres a inlet port on the left of the pic to the firing chamber.

Or another possibilty is that i just an idiot who simply doesnt look properly and its actually just a 4smoke diesal wit a turbo slapped on.

Please vote now....wait how do you do a poll?

What the hell did i just happen to pick up 2 conrods for one piston. I think im going insane. Im not following this i wana know more.

Would you like to know more?

Yes sir i would

Two contra-rotating cranks (geared together), with two conrods attached to the same piston.

Imagine a single conrod going up and down. Now add a mirror image conrod - the piston still goes up and down the same, the two conrods have the same motion vertically, but the opposite motion horizontally. The contra-rotating cranks cancel out the vibration, and the gyroscopic torque (ala the 2-stroke square-4's from the early 80's GP and GP replicas). If I remember the article in Motocycle Trader, the power is taken off one crank. The guy who designed the bike has patents on the application.

why have twin crank?
