I remember my first bike. It was a little Suzuki JR50 with just one speed and the centrifugal clutch (automatic.) When I upgraded to the Yamaha GT80 (1978 model?) with manual four-speed it was like a rediscovery of riding. I remember thinking, "So that's how they do RPM thing!" I don't mean to ramble on and on, but upgrading to the 120 didn't seem like a very big step up, because it didn't have an expansion chamber. Then, when we put on the custom pipe, it was like someone had bored it out by 100cc and put nitro in the tank. What a difference!
