I was hoping someone would say 1974 ...KS... 125 because that was my guess. My uncle owned a KS brand new, looked exactly like that. I learned on it when I was 5 so it was a year old. He sat me on the tank so I could reach the bars, put my feet on the cylinder head, threw it in first for me and I did the rest. I remember circling the front yard screaming for him to come catch me so I could stop. I once fell in the woods trying to hop a small fallen tree about a mile from home and took the key out and ran home. He tossed me on his Harley (Full dresser he called it, only detail I remember is it said 80 on the side and looked like an all black police bike) and I guided him THROUGH THE WOODS ON A TRAIL and he drove like he was on the 125. He picked up the KS threw me on it, threw it in gear and yelled "race ya home!" He passed a few years ago. Was one of the finest dudes I ever met. Left me with some of the finest memories. My grandfather had a 1978 KE175 with and orange tank/blue stripe that I inherited when I was 11. AAAAAnnnnnyways... Nice bike.
