Forget a Tire Shop with Boranni Rims - Learn to mount a tire yourself (Big Screw Drivers, Spoons and Leather - Don't scratch them Boranni's). Tubes are mandatory whether or not the Tire is Tubeless, Bias or Radial. To Balance; SPIN the wheel and use Fish Line Sinkers on the spokes until the wheel never stops in the same position.
No Chain on the rear, use a piece of wood off the swing arm to ensure the rim is straight where you have to re-torque the spokes ... etc.
A Breganzie is a COSTUM Hands On Motorcycle with less then half the Nuts and Bolts and weight of a Harley and has Superior Alloys then any Crusty Japanese MotorCycle.
Every now and then when I'm feeling my Oats and my Breganzie is clean, well lubed, I enjoy having the best of Harley or BMW chasing me.
