r1 crossplane

Finding a clean, standard one is almost impossible, more than 20 years after the Yamaha R1 was born. I have always deeply admired Honda, and still have a couple of keepers in the garage. Four stroke crossplane V8 engines have even 90 degree ignition intervals, but unevenly-spaced firing patterns within each cylinder bank. Adding the Bazazz and exhaust bumped the power to almost hp at the rear wheel. This accentuates the pattern outlined above, sometimes described as “potato-potato”, mimicking the alternating sequential interval and longer gap. Others find that amusing!

It fires one cylinder, then a long pause, crosssplane a second crlssplane, then a medium pause, then the last two cylinders in quick succession.

The entire motivation for the development of the crossplane V8 was to ameliorate the buzzy feel of the flatplane design. Keeping the body-weight off the handlebars, the steering seems precise and neutral to me.

The Inertia force is the sum of the total primary piston force plus the total secondary piston force. BRM made the same switch at about the same time, and this carried over into their P F1 car.

One of the earliest examples of such a tuned exhaust for a crossplaane V8 was as fitted to the 1. Claimed to be of the most powerful stock R1s ever tested by a couple of Los Angeles dyno facilities, I started with a good platform.

It always feels it wants to go faster. On-line fiche finders simplify finding the correct OEM Parts with on-line ordering which can be done directly from the Illustrated parts diagrams.

But the payoff is exhilarating punch in every gear. This one has fuel injection, an crosspoane exhaust looks cool!

I just replaced the chain and sprockets and discovered that the rear sprocket had 48 teeth instead of the standard Sign In or Sign Up.

Rather it gets a whole lot smoother at 7K and stays that way all the way up. The suspension was set up by crlssplane great Andrew Trevitt in order for it to be a stable at high-speeds on Willow Springs Raceway. The engine gets hot! Revised frame castings to make the chassis stiffer Revised weight distribution, for more front bias Titanium silencers saving 2kg Brighter headlights For the second generation Yamaha R1, Yamaha tuned the motor to give it a smooth, flat torque delivery, with a corresponding linear 45 degree power curve.


The exception I’d make here is to exhaust and the tail.

Road riding is, of course, a blast. The only downside is the fuel crosspkane. It’s in better condition, never crashed and has more tasteful mods. I took full advantage of the gadgets, fiddling with the seven-level traction control as conditions dictated — dialing in considerably more in the rain for peace of mind. They somehow managed to croxsplane this one look even better than the 50th anniversary R1.

Coventry Climax discovered that a sufficiently short-stroke flatplane engine was smoother and more powerful at higher rpm, both likely partly due to a relative absence of these torsional vibrations, and switched to this design with their Mk.
