Want to buy a 150cc bike. I like the CB150's design overall. The GR 150 is more durable according to people. Whichever i buy will stay a long time. I bave heard that the engine issues in CB have improved in 2023 above models. Would like to know your thoughts. I know parts are expensive for both bikes bit maintainence cost etc would be appreciated in recommendarions as well. I live in Karachi and will only use the bike for city commute.
