Southwest Ohio’s Full-Service Independent Custom Motorcycle Repair Shop.  We specialize in Performance Builds, Service, Repair, and High-End customizing of 2003 and newer Harley-Davidsons.  We respect all types of bikes and riders but we prefer to stick with what we’re best at.   

We’re a Certified Dynojet Research and Power Commander Tuning Center, ThunderMax Premier Dealer and Tuning Center, and last but not least,  Certified TechnoResearch Direct Link Tuning and Service Center!

We’ve also invested in equipment and software from TechnoResearch to be able to do everything Harley’s “Digital Technician” can do and more. It’s an all-inclusive system that allows us to do all the Diagnostics AND Flash Tuning. What does this mean to you??? We can tune your Delphi fuel injected Harley (any year) using wide-band O2 sensors.  Each cylinder is tuned individually for both air fuel ratio and timing  Also, we can program new ECM’s, keyfobs, and security modules, bleed and purge ABS braking systems, calibrate (flash) the new audio systems for upgrades, and more.
