Already tuned elsewhere?

Your Harley should feel as good as the numbers look.

Hesitation, surging, or disappointing throttle response after a previous tune? Tell Frosty’s what you’re feeling on the road. We focus on usable power and rideability across the rev range, not just a peak number on a chart.

Motorcycle Dyno Tuning FAQ

Can you tune 2024 and newer Harley-Davidson models?

Yes. Frosty’s Dyno Tuning can now direct flash OEM ECMs on select 2024 and newer Harley-Davidson motorcycles and trikes, allowing proper dyno tuning without replacing the factory ECM.

How does dyno tuning enhance my motorcycle?

Dyno tuning optimizes your motorcycle’s engine settings for maximum efficiency, enhancing power, torque, and reliability. Experience a ride that’s smoother, more responsive, and tailored to stand the test of time.

Can you modify my bike for better long-distance touring?

Absolutely. We can enhance your bike with comfort upgrades, storage solutions, and performance tweaks for the long haul.

Do you dyno tune trikes?

Yes. Frosty’s Dyno now offers dyno tuning for Harley-Davidson trikes, giving riders the same performance tuning, drivability improvements, and throttle response benefits available for two-wheel Harley models.

Do I need a dyno tune after upgrading my Harley?

Yes. Performance upgrades like exhaust, intake, cams, or engine work can change how your Harley runs. A proper dyno tune helps dial in the fuel, timing, throttle response, and power delivery so your bike runs stronger, smoother, and more reliably.

Why choose Frosty's for tuning?

Our dedication to precision and our state-of-the-art equipment set us apart, ensuring each bike is tuned to its rider’s specific style and requirements.

Rider Reviews

Hear from riders who have brought their motorcycles to Frosty’s.

  • I took my 2010 Street Glide to FKN for a stage 1 upgrade. They treated me fairly and beat Harley’s service by almost half. I now have a newer bike, and they will do a stage 2 upgrade for me. I inconveniently drive to FKN from Cleveland but it’s well worth the savings and quality of work.

  • Great people! Great communication. These guys really know what they are doing. My 02 Road King runs better now than ever before! 10/10 will definitely be back!

    Tyler Wilcox

  • The owner is very experienced with all motorcycles including metric bikes. I am very impressed with his customer service and care. He runs a very impressive garage and can do anything for your bike from increasing performance to the smallest thing. He goes above and beyond to make the customer happy.

    Jamie Burlovich
