Default Rotory Engine

Why doesn't a current Motocycle Manufacturer produce a motorcycle with a Rotory engine today??

Disregarding Norton and Suzuki, it makes PERFECT sense.

A high revving engine, super compact, super light, high yield.

The formula is all there. It may suck gas faster, but with the wieght savings and great horse power to cc and wieght, it seems to be a perfect fit.

What are we missing here? If Mazda produced the donor engines, it would be a sweet thing indeed.

It sounds good on paper, but I doubt it will work. Except maybe as a one-off custom bike.

Well, I have been personally interested in this topic myself and always wondered why no one made one. Well turns out Suzuki did, the RE-5 Rotary, which sold in 73 and 74 but apparently wasnt to succesful.

Apparently Jay Leno has one along with a video on his website

Probably worth some money if you could get your hands on one!

I'm not too sure why. They do seem like a pretty good idea. People (in general) are probably just afraid of change. They know that a standard engine works so they stick with it.

Here are a couple pretty cool links i came accross tho:

I remember the Suzuki, and there were a few others as well.

There is currently a company making a new rotoray bike based off the Rotoray Norton Racer.

They are actually in the process of getting the company name sorted. It might be a 550cc Rotory, but the engine size is unconfirmed. They are attempting to race it in Super Sport (not sure if it is World Super Sport or a British series), but they will have to produce production numbers adequate for homologation rules.

So, I think the engine size we will see, if this thing pans out, will be based on what the ruling body says is allowable. It might be a 450cc, since it will be going up against 600 I4 bikes.

The rep from the company stated that I4 bikes have so much tech in them, that the rotory he has will not be severly down in cc. So maybe a 500 or 550? I do not know.

Norton Motorcycles has been purchased by Stuart Garner. All of the trademarks and development work relating to the Norton, Manx, Atlas, Commando and Dominator brands are now owned by the British businessman and owner of Norton Racing Ltd. Plans are to return to the street and track in 2009.

After the abrupt end of the effort to bring back Norton in the U.S. and following Kenny Dreer’s departure from the company, everything kind of disappeared. There was talk of negotiations but I heard nothing until I saw this.

It looks like they’ve developed a 588cc twin rotor Wankel racebike with plans to produce 200 road versions late this year and early 2009. It also appears they have purchased the bike developed by Norton in the U.S., the Norton Commando 961, and plan to finish that project as well. Pretty cool. Now we’ll just have to see if things work out as planned. I’m rooting for their success.

Norton press release below:

After nearly fifteen years of US ownership, Norton, the quintessential and most famous of British motorcycle brands returns home.

As a result of prolonged negotiations and a multi-million pound deal we can announce that the Norton motorcycle brand is, at last, back in caring British hands.

Stuart Garner a UK based businessman and owner of Norton Racing Ltd has bought back all the trademarks and development work relating to the Norton, Manx, Atlas, Commando and Dominator brands.

Norton Racing Ltd is already in development of a new rotary engined race bike and now with the ownership of the brand itself plans are being developed to introduce a new road bike for 2009.

‘This has been a challenging and exciting period for us’ Commented Garner ‘We are proud to have brought the brands back home and we now intend to focus on re-establishing Norton as a premier motorcycling brand across the World’ he added.

In the early nineties the brands were bought by Norton Motorcycles Inc in the USA with the view of developing a new Commando road bike for the US market. Nearly $10 million was spent on IP, design and development, and this development work has formed part of the new deal. The investment can now be brought to bear on the new global project for the Norton Commando 961.

Norton intend to develop a strong presence on the track and on the road during 2009 with a new 15000 sq foot factory and office complex based at Donington Park - Norton are at the heart of motorcycle racing once again and committed to investment to make the initiative work.

As well as creating a new ‘state of the art’ road bike the Norton brands will see a vigourous licensing programme through Norton Global Brands to safeguard and develop licensing of all kinds from spare parts to clothing.

Commenting on the programme Garner said ‘Our trade marks and brand have incredible strength and value, we will strongly enforce our position as the new owners of these world famous brands and ensure our new partners benefit from a robust protection programme going forward’.

‘This is the beginning of a new and exciting era in a brand that was started over 100 years ago by James Lansdowne Norton. It has sustained ups and downs over the years but still stands for performance and excellence. These will be the standards we live by from now on’ stated Garner.
