Overlap is common on smaller bikes. Mine has some overlap. Im not a fan, but the alternative is a slacker head angle, to move the front wheel further away from the crank, and it would steer more like a bus. In reality we should have smaller wheels for smaller bikes, but Im guessing that is never gonna happen. Instead most smaller bikes have weird geometry to overcome the overlap issues and accommodate using the same fork on all frame sizes, to reduces number of SKUs. This is even true for expensive top of the line bikes. For instance the smaller size CAADs from Cannondale has very strange geometry.
