First time tube type replacement, 1982 CB125S, 700 miles, original tires/tubes/rim strips. Excellent shape all, holds air fine. Tubes, $9USD each, rim strips, $2USD each, front tire$21USD, rear tire $25USD. I'm leaning towards replacing everything as its so inexpensive compared to what I'm used to with my other bikes. I've got a HF tire changer, should be a bit easier than changing out the Concours tires.
