I read somewhere that a smaller outside diameter rear tire (same width) will help lower the bike a little, and not cause any ill effects. So- does anyone know what size would do this and still act/ ride correctly. I plan on using IRC GP 110 tires, but not sure if that brand has a smaller O.D. Tire that will do what I am trying to achieve. My plan is this + lower suspension link 1”, lower forks 1”, and cut down the seat. Any rear tire size suggestions ?.
