Series III Special 125 – Special 150

The LI special gained the looks from the TV family of models, but retained the 125 and 150 engine size options from the LI, but with more power. The 125 Special is somtimes known or called SX 125. Technically it is not a SX125 as the frame numbers are always 125LI, and there is no X badge on the scooter, but as this ran along with the 150 and 200 SX models, some people do call them SX125.
