A few years ago, we showed you the first photos of the Nembo 32, an inverted 3 cylinder engine destined for sport bike use. The intention was to build a couple of prototype bikes and test the engine and handling and work out the bugs, after which they would be ready to move on to an "on request" production model. Well, Daniele tells me, after 4 years of building and testing, they're at that point, the number 2 prototype is up for sale and they are ready to take orders for the Nembo 32, (3 cylinders, 2 liters). The two prototypes were 1814cc, all engines now will be a full 2 liters.
The Nembo website is also up and running with many pages explaining Daniele's reasoning for the rather unique engine layout for a motorcycle, comparing it to earlier aero versions. The bike is not intended as a track weapon, but is more a naked sportbike, with large displacement and compact dimensions, giving the owner an agile ride and great torque without the necessity of running at high revs to get there.
The earlier comments here debated the reasoning and function of this inverted layout, but my take is that anyone with an idea like this and the desire and capability of carrying it out is a plus in this world of "new" engines with little to justify the label. This engine is a big step out of the box, by any measure.
The bike will be very expensive, plain and simple, so these will be an infrequent sight, but with proven prototypes and more on the way, perhaps we'll see the idea carried further. I wish Daniele and his company the very best, because out of the box thinkers and doers are good for all of us.
