Types of Motorcycle Dynos
Inertia Dynos
Inertia dynos are popular for their simplicity and speed. They utilize a rolling drum that the motorcycle rolls onto, allowing for quick measurements of horsepower and torque. Dynojet’s 200i and 250i models are excellent examples of inertia dynos that provide reliable data for tuning needs. They are especially suited for general diagnostics, making them a great addition to any motorcycle shop.
Eddy Current Dynos
Eddy current dynos, such as those offered by companies like Axis Dyno, use a more complex setup involving a controlled load that simulates real-world conditions. These dynos are capable of providing precise tuning and real-time feedback, which is invaluable for race teams and performance shops looking to extract every ounce of power from an engine. This technology allows for fine-tuning of engine parameters under various load conditions.
Chassis Dynos
Chassis dynos measure the power output at the wheels, rather than at the engine. This is particularly useful for understanding how modifications affect the motorcycle’s performance on the road. Manufacturers like SuperFlow and Dynostar provide high-quality chassis dynos that are widely used in the industry for performance tuning and testing. They help identify any discrepancies between manufacturer specifications and real-world performance.
Engine Dynos
Engine dynos focus solely on the engine’s performance by testing it outside of the motorcycle. This setup allows for a controlled environment where variables can be minimized. Engine dynos are often utilized by manufacturers and engine builders for research and development. They provide critical data that can influence engine design and performance tuning.
Shock Dynos
While not a traditional motorcycle dyno, shock dynos are essential for testing suspension components. Cogent Dynamics specializes in shock dynos that measure the damping characteristics of motorcycle forks and shocks. Understanding suspension dynamics is crucial for enhancing ride quality and handling, making shock dynos a valuable tool for performance enthusiasts.
Factors to Consider When Choosing a Motorcycle Dyno
Purpose of Use
Before purchasing a dyno, consider its intended use. If your primary goal is general tuning and diagnostics, an inertia dyno may suffice. However, if you plan on competing or require precise tuning, an eddy current or chassis dyno would be more appropriate.
Space and Installation
Dyno machines can be large and require sufficient space for installation. Evaluate your shop’s layout and ensure you have adequate room for the dyno and any necessary equipment. Some models, like those from Dynojet, offer above-ground and pit options to fit different spaces.
Software and Support
The software that accompanies the dyno can significantly impact usability and data interpretation. Dynojet’s PowerCore software, for instance, integrates seamlessly with their dynos, providing detailed analysis and reports. Additionally, consider the availability of technical support, as this can be crucial for troubleshooting and optimizing performance.
Upgradeability
As your shop grows, your needs may evolve. Look for dynos that offer upgrade options, allowing you to enhance performance and capabilities without needing to invest in a completely new machine. Many manufacturers, including Bapro and RacingJunk, offer models that can be expanded with new features.
