There are several motorcycle engines that utilize two spark plugs per cylinder for improved combustion and performance. This design is commonly known as "dual-spark" or "twin-spark" technology. Here are a few examples of motorcycles that have employed this configuration:
Honda CBR1000RR: The Honda CBR1000RR, a high-performance sportbike, has featured a dual-spark engine design. The dual-spark system helps in achieving efficient combustion, improved power delivery, and smoother operation across a wide range of engine speeds.
Yamaha YZF-R1: The Yamaha YZF-R1, another renowned sportbike, has utilized a dual-spark configuration in some of its model years. This design enhances combustion efficiency, promotes better throttle response, and optimizes power output.
Ducati Panigale V4: The Ducati Panigale V4, a flagship sportbike from Ducati, features a four-cylinder engine with dual-spark technology. This arrangement helps in achieving improved combustion and enhanced performance characteristics.
KTM 790 Duke: The KTM 790 Duke, a naked streetfighter motorcycle, utilizes a parallel-twin engine with dual-spark plugs per cylinder. The dual-spark setup aids in efficient combustion and better power delivery, contributing to the bike's overall performance.
Please note that specific models within these motorcycle ranges may vary in terms of their engine configurations, including the use of dual-spark technology. It is always recommended to consult the manufacturer's specifications or product literature for precise information about a particular motorcycle model.
