Why does the new r1 sound different

But this is based on extreme track use, so it very much depends on how you use it. Flat-plane cranks are inherently well balanced — unlike cross-plane cranks. Flat-plane crankshafts are generally associated with European sports cars such as Ferrari and Lotus V8 engines, and cross-plane cranks with American manufacturers. Flat Plane Crankshaft Advantages: Lighter, more compact, more responsive high-revving , better exhaust scavenging.

Flat Plane Crankshaft Disadvantages: Prone to vibration, lower torque levels. This one is another beast in the form of a bike. This bike is one of the most powerful production motorcycles. Completely new crossplane crankshaft design to increase the throttle and drive ability by reducing the inertia force. Yamaha literally changed the liter bike category with the R1.

R1M is a Street legal bike and with the adaptive suspension more suitable for street riding than the standard R1. Skip to content. Search for:. Home » QA. Now, the YZF-R1M—a very special machine designed to offer top performance on the racetrack for a select few riders—makes its debut as the latest product of a development approach that is full of uniquely Yamaha innovations. Born in Tokyo, Japan in However, from the moment I accelerated out onto the test course, my nervousness changed first to surprise and then gradually into a feeling of delighted excitement.

Using the quickshifter, I rapidly shifted up without touching the clutch lever. That experience was exceptional; it was something I had only felt until then with a MotoGP machine, and it immediately made me feel what this meant in terms of performance.

Another thing that added to and deepened my excitement was the unique exhaust note. Being a street-legal bike, it has to comply with regulations for absolute noise volume; the sound was being muffled. But the unique and composite mix of different sound frequencies and the clear and crisp pulse you feel through the mid-range remains distinct without blurring into a continuous drone, even up into the high-speed range around 13, rpm.

It conveys a sense of the linear rise of power being transmitted to the pavement. A bit embarrassed by the unexpected delight I was feeling inside my helmet for someone my age, I made an effort to relax and refocus my attention on the ride.

Of course, the purpose of the crossplane crankshaft is not to produce this unique sound. The in-line 4-cylinder engine configuration is one that has little vibration and good balance under steady-state conditions such as continuous acceleration. Although this tendency occurs only at the precise moments of opening or closing the throttle, the behavior it causes during cornering can feel very unsettling for a sensitive rider.

Of necessity, this change in the firing interval results in the unique tone of the exhaust sound. It goes without saying that this is all feedback from development of the YZR-M1 MotoGP machine, but some might question if the differences are so clear that even the everyday rider can feel them. With the R1M, I found myself being constantly amazed by the difference.

The more advanced extreme-performance machines like this become, the more tangible the difference is in whether or not the machine is able to reduce those momentary feelings of tension a rider experiences while riding it. On the R1M, this is especially obvious with the subtle rider support provided by the suspensions.
