  • Rated 5 out of 5

    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!

    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.

    Skip is a stand-up and stand behind his work kind of man. I'm very happy with my 15 Ultra Limited and how it feels now. Stock 103 liquid cooled with S&S air cleaner and complete Vance & Hines header to crossover and pipes.
