I started the climb down the displacement ladder about eight ago. I maxed out at 1500cc with Goldwings,cruisers and a Harley. Now I am down to 500cc, 225cc, and 170ccs with the 500cc bike soon to go on the selling block. My small bikes will exceed 70 MPH which is plenty fast for the type of riding I do now. Soon I will be back to where I started fifty plus years ago with a mini bike. Looking to buy a CT70 clone (110cc) soon.
