The power output of an engine is determined by various factors, including its design, configuration, tuning, and intended use. While the Yamaha XJR 1300 has a 1251cc engine, the power output of 98PS (or approximately 96 horsepower) is a deliberate choice made by Yamaha for that particular model.
There are several reasons why Yamaha may have decided to limit the power output to 98PS for the XJR 1300:
Intended use: The XJR 1300 is a retro-style motorcycle designed for street riding and cruising rather than aggressive performance. Yamaha may have opted for a power output that provides a balance between performance and manageable power delivery for everyday riding scenarios.
Rideability and torque: Power delivery is not solely dependent on engine displacement. Other factors like torque characteristics, gear ratios, and overall engine tuning can greatly influence how the power is delivered to the wheels. The XJR 1300 may prioritize torque and low-end power delivery, which enhances its street riding capabilities and overall riding experience.
Emissions and regulations: Motorcycle manufacturers must comply with various emissions and noise regulations in different countries. Limiting the power output to a specific level can help meet those regulations while still providing a satisfying riding experience.
Market positioning: Yamaha may have positioned the XJR 1300 as a mid-range power motorcycle within their lineup. By offering a specific power output, they can create differentiation between models and cater to a specific target audience.
It's worth noting that power output figures can also vary depending on factors such as the region or market where the motorcycle is sold, as regulations and customer preferences may differ. Ultimately, the specific choices made by Yamaha regarding the power output of the XJR 1300 are based on a combination of performance goals, market considerations, and intended use.
