1950 Model 125

 

The 1950 Model 125 was available in colors! You now had the choice of Sportsman Yellow, Flight Red, and Riviera Blue, in addition to the ever-popular Brilliant Black.

The big visible change for 1950 was the new American style solo seat, which replaced the English-style seat used in 1948 and 1949. A one-piece front mounting bracket replaced the former two-piece unit.

The frame was strengthened by changing the fork neck to a forged unit. The jiffy stand, formerly a bicycle-style unit mounted on the frame, moved to the more familiar footpeg shaft location. Both these improvements were detailed in a 1950 factory to dealer announcement.

Engine changes: The flywheels were changed. The piston pin is larger, so the connecting rod, piston pin bushing, and pistons changed also. The generator changed from 2-brush to 4-brush. There were 4 Shop Dopes about the new generator, including a factory recall of the 2-brush units. A new fuel valve appeared in mid 1950. The new valve is the familiar pot-metal valve with main and reserve handles.

More little changes: the taillamp has a new bulb, and the taillight wiring connector has a rubber bushing to keep water out. The front fork upper snubber has changed slightly. A spacer has been added to the coil mounting bracket. The clutch cable has a few minor changes, and the clutch hand lever uses a new bushing. The fender rivets changed sometime in mid-year.

Jiffy Stand and Footrests

A new jiffy stand was announced for 1950, although it appears that it was introduced in late 1949. The new jiffy stand is problematic - the "tang" does not always engage, allowing the jiffy stand to swing past the stop point.

The footrests continue to be fixed. The left footrest shaft now has a bracket for the jiffy stand to pivot on.
