It's had a cosseted life, with both myself & the PO. I bought it with 9k on the clock & FSH about a decade back. Oil changes done twice as often as recommended etc. In the '70's Honda 125's often needed rebuilds due to cam issues, IIRC. Used to see a lot of those as an RAC/ACU instructor. We replaced them with Suzuki Bloops or A100's, I think. A lot of the instructors had 400/4's, they also had issues. Cam & primary chains, chiefly.
Things of course have changed since then. But I don't think Hondas are any more reliable than other Japanese bikes.
