Types of Motorcycle Dyno Machines
Inertia Dynamometers
Inertia dynamometers, such as those offered by Dynojet, measure the power output of a motorcycle by accelerating a heavy roller and calculating the force required to do so. This type of dyno is ideal for performance tuning because it provides accurate horsepower and torque readings at various RPMs. The Dynojet 250i, for example, incorporates advanced software to deliver precise diagnostics.
Eddy Current Dynamometers
Eddy current dynos, like those from Dynostar, utilize an eddy current brake to create resistance, allowing for more controlled testing conditions. These machines can simulate real-world riding conditions, making them suitable for research and development of aftermarket products. The Dynostar D70, with its high inertia drum, offers dynamic measurement up to 465 kW.
Chassis Dynamometers
Chassis dynamometers, such as those available from Bapro, are designed to measure the power output at the wheels of a motorcycle. They are often used in motorsport and tuning applications. The Bapro HP Series features high-performance rollers that ensure accuracy and repeatability, making it perfect for precision tuning.
Portable Dyno Machines
Portable dyno machines are compact and allow for on-the-go tuning services. While they may not offer the full range of capabilities found in stationary models, they are invaluable for mobile mechanics and race teams that need to diagnose performance issues at different locations.
Applications of Motorcycle Dyno Machines
Tuning and Performance Enhancements
The primary use of motorcycle dyno machines is to tune and enhance performance. By measuring horsepower and torque, technicians can make informed adjustments to fuel mapping, ignition timing, and other engine parameters. This process is vital for both street and track motorcycles.
Diagnostics
Dynos are also essential for diagnosing issues in motorcycle engines. By analyzing performance data, technicians can pinpoint problems such as fuel delivery issues or engine misfires, ensuring that motorcycles run efficiently and reliably.
Research and Development
For manufacturers and aftermarket parts developers, dyno machines provide crucial data during the development phase. By testing various components and configurations, companies can optimize their products before they hit the market.
Racing and Competitive Events
Racers often use dyno machines to fine-tune their bikes for optimal performance during competitions. Understanding how modifications affect power output can be the difference between winning and losing.
