Don't like to contradict you........BUT....... the forks are the early forks as fitted to the ETS between 1969 and 1973. These have chromed steel bottoms and are just about impossible to take apart unless you have the proper tool, and even then it can be a total pain!
Here is a picture of an ETS 150
Then there came your TS150. If memory serves the tank, rear aluminium part of frame and seat are different to the ETS
Then comes an intermediate. This has the later forks with aluminium sliders , which necessitates a different front mudguard and brake plate.Also has a different mounting for the rear light
And finally the last incarnation of the TS150. Later forks, different headlamp, and rev counter and speedo on aluminium dog ear brackets
So there you go, a quick history of the evolution of the TS150!
ES250 Doppelport, ES250, ES250/1, ES250/2,ETS 250, ES150, ETS150, BK350, IWL Pitty, SR56 Wiesel, SR59 Berlin, Troll............ and thats just the German two strokes!
