Cheap way of going very fast but ugly, heavy, dangerous brute with engine that wrecks cams, breaks camchains and clutches, and can seize up. Tourers last for 40k but fast riding needs engine work every 20,000 miles. Poor running may just be naff coils. Upgraded suspension, Pirelli tyres and rebuilt calipers make the CB more useful. Do a compression test on engine.
