Buddy just got a ninjette for track and needs new tires. Would have sent him to MarMo. What shops are up Roswell/Alpharetta these days?
DucShop may take care of him, MSP is on the east side ITP but can handle that. I don't think there are many non-dealer chain shops in that area anymore.
Theres the new Triumph of Roswell....formerly known as Pops garage. They are not racers, but if you know what you need they could probably handle it. Richard is their Service manager.
Scott Morris, owner of MiH Powersports in Cumming, has his WERA National Championship YZ450F racebike in his office. Great, stand up guy, diligent and experienced shop owner. Been dealing with him for 5-7 years. https://www.mihpowersports.com/index.html
