Stroker advantage

ride a bike with 170mm cranks, then ride the same bike with 175-180mm cranks. The 175 rides alot easier, requiring less pedal pressure to move the same mass because the 'levers' are longer. You do lose upper RPM torque as it usually drops with RPM after a point . There is a happy medium. Growing up, Murray and Huffy Cruiser bikes (big tire bikes) has the 170mm cranks and the Schwinns had the 175 or 180. The Schwinns were so much easier to pedal as they had more mechanical advantage on the longer crank arms. I think strokers are popular as they give you a 15-20% boost in CID with only 2 new components, crank and piston, as well as a huge boost in torque that is great for street driving. As Yellow Rose stated, I think drag apps would rather have the increase at the upper end with the stock stroke and higher RPM potential without the higher piston speeds of a stroker.
Question: "Why don't you stroke it?"
Answer: "Because it will cost me another $800"
