After all, 48 is already a Sportster model, so a 48X is likely to be a special edition, perhaps with a bigger engine. And Bronx is a tough New York neighbourhood, befitting the image of either the urban Sportster cruiser or new Dyna/Softail range.
The Sportster range is certainly in need of an update.
The 883 and 1200 Evolution engines are getting old and they still have five-speed transmissions. They may also get mono suspension like the new Dyna/Softail range.
Or the Sportster range could be dropped altogether as was the V-Rod this year.
Perhaps the new Bronx will be the fourth model in the Street range which consists of the 500, 750 and Street Rod.
A bobber or street scrambler style would be most welcome.
