While it is true that turbocharged motorcycles are not as common as turbocharged cars, there are a few reasons why turbocharged motorcycles are not as prevalent. Here are a few key factors:
Power-to-Weight Ratio: Motorcycles have a significantly higher power-to-weight ratio compared to cars, which means they are already quite powerful in relation to their weight. Adding a turbocharger to a motorcycle engine can result in a substantial increase in power output. This can make the motorcycle more difficult to handle, especially in terms of managing the additional power and torque.
Size and Packaging Constraints: Motorcycles have limited space for components due to their compact design. Adding a turbocharger and the associated components, such as intercoolers and piping, can be challenging from a packaging perspective. It can be difficult to find suitable locations to accommodate these components without compromising the motorcycle's handling, balance, and overall design.
Heat Management: Turbochargers generate a significant amount of heat during operation. Motorcycles, especially sport bikes, already face challenges in managing heat due to their high-performance nature and tight packaging. Adding a turbocharger would further increase the heat generated, potentially leading to overheating issues if not properly managed.
Cost and Complexity: Turbocharging adds complexity to the engine design and increases manufacturing costs. Motorcycles, particularly mass-produced models, are often designed to be cost-effective and accessible to a wide range of riders. The additional cost and complexity associated with turbocharging can make motorcycles less affordable and less appealing to a broader market.
These motorcycles often fall into the high-performance or specialty category, where manufacturers aim to push the boundaries of performance and technology.
Overall, while turbocharged motorcycles exist, their limited presence can be attributed to factors such as the already high power-to-weight ratio of motorcycles, packaging constraints, heat management challenges, and cost considerations.
