“Go Big or Go Home” Yamaha It seems to live up to that slogan thanks to its stellar parallel motors. When it comes to sheer engineering prowess in the motorcycle world, Yamaha has been at the forefront of it along with other big names like Suzuki and Ducati among others. Yamaha makes incredible motorcycles. But their strong lineup of CP2 parallel twin engines takes center stage. The company takes a one-size-fits-all approach with its parallel twin engines that symbolize versatility, efficiency and power.

We have updated this article with more interesting facts about the famous Yamaha CP2 700cc parallel twin engine. We’ll tell you why this parallel twin is suitable for everything from track-ready sportbikes to dune-crushing ADVs. We also give you a brief history of Yamaha’s popular parallel-twin engine.

Specifically, we’re talking about the Yamaha CP2 689cc parallel-twin engine, as seen on like the XSR700 and Yamaha MT-07. While V-Twin engines are extremely attractive, not all two cylinders provide long-term reliability. This is where Yamaha’s parallel twin is successful. It is not only suitable for incredible reliability, but also has many important applications, even in dirt track racing or track racing. But that’s just the tip of the iceberg, because Yamaha’s parallel-twin engine is as good as it gets.

History of CP2 Yamaha 700cc engine

The CP2’s predecessor began life as the heart of the Paris-Dakar winning motorcycle.Yamaha XTZ 750. It was this engine that became the iconic Yamaha TDM line of sport touring bikes in the 1990s through the mid-2000s. There were three generations of TDM bikes – the 850 MK1 (1991-1995), the 850 Mk2 (1996-2001) and the 900 5PS (2001-2010). These motorcycles were designed to be comfortable, agile and powerful. This was the origin story of the famous CP2 parallel engine that we love today.

The CP2 parallel twin engine was launched back in 2014 when Yamaha introduced the MT-07 in Australia, Europe and Canada. Subsequently, the motorcycle entered the United States under the name FZ-07 in June of the same year. The CP2 later found its way into the twin-sport Tenere 700. The parallel-twin CP2 also found its way into the new Yamaha YZF-R7 after the company failed to meet Euro-5 standards and was forced to abandon the inline-four YZF-R6. . It’s quite unconventional to see a two-cylinder supersport in a competitive arena filled with four-cylinder options. But this engine still manages to check all points.

Yamaha’s 700cc parallel-twin engine is one engine that can do any job. The CP2 engine can even be seen in Yamaha’s newest entry-level supersport, the YZF-R7. The 700cc CP2 Parallel-Twin has a compact profile and vertical transmission. The CP2’s 689cc parallel-twin engine can produce a powerful and respectable 75 hp. with 50 lb-ft of torque perfect for sharp cornering.

The engine is tall, but does not take up much space. And to soften the vibration, we got a balancer. Bore and stroke are 80.0mm x 68.66mm, and the compression ratio is 11.5:1. As for fuel consumption, Yamaha claims the engine is capable of 58 mpg on 86 octane fuel. Expect an oil change every 4,000 miles. As for valve maintenance, expect minor checks every 26,000 miles.

That’s what makes the Yamaha CP2 700cc Parallel-Twin so refined

The CP2 is primarily a DOHC parallel-twin engine that features a crankshaft known as a crossplane that rotates 270 degrees. But how does it work? The engine has a powerful torque, the crankshaft with a rotation of 270 degrees provides incredible acceleration with minimal vibration. The principle of operation is that one cylinder is activated in the plane of zero degrees, and the other – at an angle of 270 degrees to the first. The crank rotates 500 degrees before firing the next pulse of power – rinse and repeat.

Parallel twins are quite light as the engine is mostly cast in one piece, making them quite strong.

This durability ensures support for many usage scenarios. The aluminum construction of the pistons with direct coated cylinders built into the crankcase makes the engine quite light. In addition, it is incredibly resistant to distortion at high speeds and temperatures. Kawasaki adopted Yamaha’s parallel engine in its Ninja 650. And it’s made even better knowing that this engine can put up a fight in high-stress scenarios like dirt track racing.

Regardless of the specifications, the CP2 engine is ideal for every rider. Whether you’re just starting out or progressing, the 700cc parallel twin engine delivers great results. It is perfect for any highway, track or even dirt road, as seen with the Tenere 700. Although it is not an ideal engine for racing bikes, it is also seen on super sports bikes such as the YZF-R7 and the sport tourer Kawasaki Ninja 650 , making it one of the most versatile engines available today. What makes it ideal is that it can produce decent torque in the lower rev range.

This makes the CP2 ideal for dirt roads, especially on the Tenere 700. This does not mean that this engine is suitable for daily commuting. Yamaha’s parallel-twin engine is great around town in the 2000rpm range and at highway speeds at 5000rpm. Regardless of revs, the overall compact design of the engine makes the bikes nimble and manoeuvrable. This is another reason why the Yamaha CP2 parallel-twin engine is uncomfortable for city trips, active rides and dominating twisty roads.

As for engine reliability, there have been no reports of engine failures. Tenere 700 forum focuses on the same CP2 parallel-twin motorcycle. Some members are comfortably racking up nearly six-figure miles without checking their valves. This proves that the CP2 Parallel-Twin is as reliable as it gets for a motorcycle engine. In addition, it is easy to maintain without compromising reliability.

Parallel Twin vs. V-Twin: Which Is Better?

Both parallel twin and V engines have their fair share of advantages. V-twin bikes are more expensive than parallel twin bikes. They are narrower, have more moving mechanical parts and are more expensive to manufacture, hence the price. The twin V-engines create an unmistakably great sound exclusive to Harley-Davidson and Ducati motorcycles.

After all, parallel twin motors are more affordable and also deliver impressive torque and performance figures. In addition, they are cheaper to maintain. In terms of reliability, parallel twins are reliable compared to V-engines due to fewer mechanical parts. But there is no good or bad engine at the end of the day. Both mechanisms have their own sets of advantages, and it comes down to personal preference.

Parallel twin engines have stood the test of time

The parallel-twin engine has been around since the beginning of motorcycles. It has been the mainstay of the British motorcycle industry for almost half a century. Even Harley-Davidson and Ducati initially started with parallel twin engines before moving to the more powerful V-engine.

In 2023, the parallel twin bike made a big comeback. It’s relatively light, torquey and powerful, but only takes up a small amount of space on the bike frame – another reason parallel twins are so narrow. A parallel twin engine inherently suffers from vibration problems due to the piston rods moving up and down, but balance shafts easily solve this problem.

The parallel-twin engine has come a long way since its introduction in 1895. It’s amazing to see such an old engine setup still relevant after more than a century. Motorcycle giants like Kawasaki, Triumph, Yamaha, KTM and BMW use the parallel twin in their two-wheeler lineup.
