Suzuki Developing New Middleweight Parallel-Twin Engine
The engine is likely to replace the Japanese bikemaker's 650cc V-twin motor.
Patent images of a new Suzuki parallel-twin engine have been released online, revealing details about the motor that would power middleweight motorcycles from the Iwata-based firm.
Filed last year, the patent pictures reveal an engine that is similar to that of the DOHC XE7 concept showcased two years ago. However, the concept was a turbocharged mill, while the latest patent images reveal an engine that is naturally aspirated.
As we can see in the images, the catalytic converter is placed diagonally across the front of the engine, and overall, the design looks compact and simple.
Expect it to churn out between 70 and 80 HP, while displacing 700cc. Thus, the motor will effectively replace the manufacturer’s current 650cc V-twin mill that powers the Suzuki V-Strom 650 (the BS6 version of which is expected to launch soon) and models like the SV650 sold overseas.
Losing a V-twin engine would mean certain characteristics that the configuration brings would be lost as well, but there are advantages in making a parallel-twin engine, chief of which is cost reduction.
A parallel-twin will only need a single camshaft, one cylinder head and fewer components in comparison to a V-twin, which will make production that much easier and make the accountants happy.
We expect Suzuki parallel-twin engine to power future middleweight roadsters, possibly touring and adventure-oriented bikes and rival the likes of Kawasaki’s 650 models for example. Launch of the engine might take place as early as 2021.
