It is the rare occasion in the USA that I see a bicycle with the right brake lever set up to control the front brake. The exceptions are bicycles made for the UK market that end up in the US, or a bike that has had the controls swapped for a rider that prefers it that way. The UK bikes right brake lever are set up to control the front brake. I always think of as similar to the UK cars that have the steering wheel in the right versus US cars that have the steering wheel on the left.
