I went riding yesterday. My riding buddy needed a new back tire, and since there is a shop on site with good prices he decided to let them mount the tire for him. I struck up a conversation about the bikes in the shop, and the mechanics stated they have all switched to back two strokes, as they could not afford to maintain the strokers. They said a $1,200 rebuild made it an easy decision to switch.
While riding I noticed more smokers around. I asked a few and they started laughing that the potential cost of a major rebuild keeps them on smnokers. In fact, all but one in their group was on smokers. The lone stroker on a 250F just purchased his bike. He just turned 20 and this was his 2nd bike, the 1st was a Honda 50... He tried his buddies, but couldn't get used to the powerband.
The tide is definitely changing.
