Yamaha YZF-R7 officially launched for European and North American markets. This sportbike is projected as the successor to the Yamaha YZF-R6 which has been injected to death since the end of 2020. Interestingly, yamaha R7 carries a different engine configuration, where this bike uses a 2-cylinder engine, whereas previously Yamaha R6 uses a 4-cylinder engine in line. So what's the reason Yamaha pinned a 2-cylinder engine on the R7?
Yamaha YZF-R7 is finally reborn with a more modern look and contemporary technology. For the uninitiated, the Yamaha R7 existed in 1999, as a homologation product of the Superbike World Championship and suzuka 8 Hours endurance racing. This sport bike is only produced as many as 500 units around the world.
Now yamaha YZF-R7 reborn with a 689cc engine, 2 cylinders, which has been tested. Here are some reasons why Yamaha uses a 2-cylinder engine on this bike:
The machine is more environmentally friendly.
The 2-cylinder engine carried by the Yamaha R7 is more environmentally friendly. This engine has passed euro5 regulations, so it can be marketed in Europe which has strict emissions regulations. For information, the reason Yamaha was injected to death in Europe is because it did not pass euro5 regulations.
No need to build a new machine
In addition to being more environmentally friendly, the Yamaha R7 2-cylinder engine also has other advantages because it is an engine that has been used in several types of Yamaha motorcycles, such as in the MT-07, XSR700, and Tenere 700 models. By using the engine platform of the existing model, it means that Yamaha does not need to develop a new engine anymore, so there is no need to do new engine research that usually costs a lot.
Powered Engine with Compact Size
The Yamaha R7 adopts a 689cc, 2-cylinder engine, Crossplane 2 (CP2), DOHC, 8 valves, liquid-cooled, and Euro5 compliant. The engine has a maximum power of up to 73.4 PS at 8,750 rpm with a maximum torque of 67 Nm at 6,500 rpm.
The engine is still far less than the Yamaha R6 4-cylinder engine, which can release 123.7 PS of power at 14,500 rpm. But in torque, the Yamaha R6 engine can only emit 65.7 Nm at 10,500 rpm.
However, the Yamaha R7 engine has another advantage due to its compact size and lighter weight. In addition, the torque is also larger and can be achieved in lower engine rotation. That is, this engine is certainly comfortable to use for daily driving.
