Unleash the Full Potential of Your Bike with MSS Performance

For over 40 years here at MSS Performance, we are passionate about helping riders get the very best from their motorcycles. Whether you’re chasing lap times on the circuit, aiming for a smoother ride on the road, or simply want to know exactly what your bike is capable of, our state-of-the-art dyno facilities and experienced technicians are here to deliver.

What is Dynoing?

Dyno testing, or “dynoing”, is the process of measuring your motorcycle’s performance using a dynamometer. This specialised equipment allows us to accurately assess horsepower, torque, and fuelling under real-world conditions, providing invaluable data for both diagnostic and tuning purposes.

Our Dyno Services

· Power Runs: Get a clear, honest assessment of your bike’s current performance. You’ll receive a detailed printout showing power and torque across the rev range, highlighting any areas for improvement.

· Custom Tuning: Our technicians use the dyno to fine-tune your fuelling, ignition timing, and other parameters. We work with a wide variety of aftermarket ECUs and fuel modules to extract maximum performance and rideability tailored to your needs.

· Diagnostics: Struggling with flat spots, hesitation, or inconsistent power delivery? Dyno testing helps us pinpoint the root cause, ensuring your bike runs smoother and more reliably.

· Aftermarket Upgrades: Fitted a new exhaust, air filter, or other performance parts? We’ll ensure everything works in harmony, optimising your setup for both power and longevity.
