The MODEL S has the same chassis as the 1907 model except the wheelbase on all body styles increased to 2083mm and full running boards replaced the step plates. Single and double rumble seat options were available on the straight line or Victoria styles runabouts. If rumble seat passengers were to be carried regularly, it was recommended that tire size be increased from 30 x 3 to 30 x 3-1/2.

DRIVETRAIN OPTIONS

  • On the models M, S & T, different combinations of 9 or 10 tooth driving sprocket with 31, 34, 38, 41, or 45 tooth driven sprocket gave ten possible ratios from 3.1:1 to 5:1.
  •   Driven Sprocket
      31 34 38 41 45
    9 tooth drive sprocket 3.44 3.78 4.22 4.56 5.00
    10 tooth drive sprocket 3.10 3.40 3.80 4.10 4.50
  • Lower ratios for runabout to be run on smooth, level roads to higher ratios for loaded Delivery to be run on rough, hilly roads.
  • Instructions for changing sprockets were available for owners, but the change involved disassembly of the transmission and rear axle -- definitely not a "quick-change" set-up.
