How it all started

It all started a white sheet of paper at an meeting in the paddock building at circuit near Capetown in Africa. The world-s best journalists were just the newly launched YZF1000R Ace. While the media was on this new Yamaha sportbike in the hot and South African environment, a of Yamaha Japan-s key engineers the opportunity to discuss some new with Yamaha-s European planners in this relaxed

Kunihiko Miwa, the man behind the had just been promoted leader of a new supersport machine-. Inumaru, senior product and responsible for the whole European favoured the idea of a really machine. His vision was to rejuvenate the supersport class. Sales of bikes had slowed down in the of the nineties, but Europe was always a market for real supersport

The planners in Yamaha Motor office in Amsterdam believed in segment, and were more happy to have an engineering in Japan that supported ideas.

No compromise

So while the top motorcycle journalists were out the Thunderace, the little group of and planners in the paddock building to them were already of their next, more concept! Mr. Miwa told the that he had already started a for a brand new 4 cylinder engine, and he to integrate its chassis and engine one unit in order to make new bike the lightest and most in the class.

He took his pencil and his basic technical idea on the sheet of paper. The planners at it. Someone took a pen and added the NO COMPROMISE-.

This later became the key for the whole development of R1. Miwa-san had a burden put on his shoulders when laid down the basic 150 HP, under 180 kg and handling like 600 cc at that time!

New layout valid today

Mr. Miwa and his worked hard for about a Not much free time was for sushi and sake. (for not familiar with Japanese these are raw fish and rice-wine). The layout the engineers came up is still valid today, and it sets the standards by which supersport machines are judged:

Ultra-short 4-cylinder engine a triangular crankshaft and gearbox layout

— Deltabox II with the slant-block engine as member to ensure high and low weight

— Ultra-long combined with a short for superb handling together excellent stability

— position in the centre of the bike to best weight distribution

Careful attention to details

has a high-volume production machine the R1 received so much attention to the smallest detail, and Mr. Miwa was called Mr. No Compromise-.

Here are some examples of his search for in order to make a straight linkage from the R1-s lever to the gearbox shaft, a was designed in the frame section the swingarm pivot shaft. innovative solution resulted in a shift feeling, because of no moments on the shaft. The handlebars are aluminium, and are 46% lighter than welded counterparts.

These are two examples of how Yamaha-s attention to makes the R1 one of the most advanced machines on the market.

R1 and R6: The top class supersport

R1 and R6 are Yamaha top class supersport One could think, the 600 cc is just a version of the 1000 cc version. wrong! Both bikes are different!

Engine, chassis and riding of both R1 and R6 are targeted for different Kunihiko Miwa, the man behind R1 and R6 the differences.

Yamaha YZF-R1

Without taking a look to Yamaha’s 600 and 1000 bikes, you may think they are much the same. One is just a version of the other one.

Completely wrong.

Now you would away ask the question: Why does not use common parts on both It would certainly be cheaper and less development time. Miwa, who was responsible for both the R1 and the R6 as leader, always shakes his when people bring up subjects.

Says Miwa: If you to build a perfect supersport you can not make faulty compromises. A 600 cc has to have a different character a 1000cc bike. Naturally, physical size and engine will be different.

If you try to use a 1000 chassis for example, you automatically weaken certain of a 600 cc.

Miwa goes on in his explanation:

we developed both bikes, our was ‘EXCITEMENT’.

Of course there are variations of excitement for motorcycle For supersport this certainly hard riding and exploration of the potential. The rider should be to feel: When I do this or I can take the corner in the best way. I mean, it is not about speed, but more about the for this interactive response the bike and the rider. It should be a good conversation from man to and vice versa.

This excitement and satisfaction. So both R1 and R6 are towards rider control on type of twisty road, and not to ride with high

To achieve this target, the had to make the bike as light as and at the same time take of the best balance between engine and controllability. Both were never aimed at high speed or high performance alone. In order to both machine a pure character some practical had to be sacrificed.

For example tandem storage space or wind etc.
