Repair Shop - Buenos Aires
 

There have been recommendations for Dakar Motos in here, they are currently relocating, the owner Javier was kind to enough to redirect me by email.

There is a block of bike shops on Av Pueyrredon between Calle San Luis & Av Cordoba.

Avant Motos (980 Av Pueyrredon) was the best value for Honda parts and have a showroom if you want accessories. A few shops have workshops including Avant Motos, and there looked like an independent workshop on Bologne Sur Mer (avenue parallel with Av Pueyrredon i.e one block away)
