Not just dirt bikes...
Though it is good to be focussed on your interest, now and again other things can catch your eye. For some inexplicable reason, CDB’S editor likes early American motorcycles such as this Henderson four-cylinder. Tom and William Henderson built th heir quite advanced four-cylinder motorcycles in Detroit until the company was sold to Chicago-based Schwinn cycle manufacturer in 1917. This particular bike was built in 1914 and as such could have been ridden in the fledgling trials of the time.
