  • Here's a bike that's hard to place – it's the Harley-Davidson Nova, of / It was a V4 for a start, liquid-cooled and, revving to nearly 10,rpm, around twice as powerful as any Harley of the time. Harley got so far down the line as to have built 30 engines, 12 complete.

    So have you ever heard of the Harley Davidson NOVA? development and testing, and with a planned release date of mid, the Nova project had at least.

    Will Harley revive its long-rumoured V4 project? Project Overlord, and shares similarities in thinking with the s Nova V4 project. Just as.

    The Big Bore is an interesting comparison. Twin scoops routed through a dummy tank fed it with air, while the fuel was displaced into that bulging midriff. Then it was dumped after only two or three years before it could be improved. And almost as important at the time, the "invisible" radiator kept Willie G. Other pages you might like

    Harley-Davidson's Roads Not Taken | Motorcyclist

    Here's a bike most motorcycle folks have never heard of, the Harley Davidson V4 Nova. Bob Horn brought this up in a comment yesterday and pointed to a pretty interesting page that tells the story of a motorcycle that might have been and I thought it deserved a story of its own. At the time the Shovelhead's replacement was being designed the engine that eventually became the Evolution V-Twin , another engine and motorcycle combination was in the works.

    The Nova project was to be a smaller displacement family of high tech water cooled engines in V-Twin, V4 and V6 configurations. The cylinder sizes of either cc or cc gave engine size options ranging from a cc V-Twin to a cc V6, and lots of interchangeable parts. The heads were 2 valve overhead cam with the potential for 4 valves at a later time.

    Although the project had advanced to where they had 30 engines and 12 running motorcycles, it was never produced, a casualty of the AMF years. The article is fascinating and if you are interested in H-D technology it's worth reading the whole thing. Thanks for the pointer, Bob! HD has the most loyal fan base of any bike maker. HD fans even tatoo themselves with the HD logo. One of their chief reasons for their loyalty to HD they say is because it is made in America.

    Ducatis and the Honda RC51 both use 90 degree vtwins. The Aprilia motorcycle uses a 75 degree vtwin. On 45 degree vtwins, such as the ones HD uses, heavy counter weights are needed to keep the motors momentum turning and also to keep it from shaking to kingdom come. This robs horse power and makes the engine run slow. If you want high performance the air cooled 45 degree twin has huge draw backs. The air cooled 45 degree twin needs to stay in the rolling sofas or in the bicycle frames from which it was born.

    There are too many better alternatives available. Harley designed their engines something which often gets mistaken — they farmed out the development. Detroit was busy doing such technological tour de farces as the Fairmont and Citation.

    When Chevy wanted the Vega to go faster, they went to Cosworth. It was designed and built by Cosworth, in England. Chrysler was doing its best to go out of business, only to get saved by a government loan and come out with FWD cars — based on VW engines and with some models from Mitsubishi. The main reason for water cooled engines is noise management, not power or tolerances. Totally and completely impossible.

    Respond separately or refer to the prior comment, otherwise, one will be deleted. We are starting to see some of those differences with engines like the X-Wedge and the Big Bore Guzzi application. The Big Bore is an interesting comparison. By comparison, the aftermarket billet degree v-twins such as Patrick Racing used on the Ecosse Heretic, which is cc makes hp at the rear wheel. So, what is holding the 45 degree design back from making more power? The smaller engines with a wider v design are making a disproporationately greater amount of power.

    Does the Moto Czsyz design throw too much of a big wrench into this discussion? Seriously, there could be some good parallels to pull into the discussion above with the Z4 from Czsyz. They have a very narrow v-angle but are smoothing things out with counter-rotating cranks instead of heavy counter weights. They seem to be pleased with the power, but apparently that has been a significant challenge with that design in relation to making similar power output with other designs.

    I think HArley was right on having a higgh tech engine development company such as Porsche engineer its motors. I think the compromises that had to be made to accommodate the under seat radiator and side-saddle tanks is worse than a simple raiator out front. If the design had a conventional radiator and gas tank it might not have been looked at as such a risky venture.
