If you have been riding long enough to have opinions about oil, this was written for you.There is no shortage of motorcycle content. Most of it is aimed at somebody who just got their license and wants to know which 300cc bike to buy. This is not that.This is for the rider who has been on two wheels for twenty, forty, sixty years. Who has owned more bikes than cars. Who can tell a chain that needs lube from three rooms away.WHAT'S INSIDE — 109 pages, six partsPart I — The buying guideWhich used bikes are genuinely worth the money and which are money pits wearing chrome. What to pay, with real private-sale ranges. A pre-purchase inspection you can run in ten minutes. The bikes, years and engines to avoid.Part II — Wrenching at homeThe maintenance that actually prevents breakdowns, ranked by what it costs you when you skip it. The five jobs worth doing yourself. Tricks mechanics use on their own bikes. Storage, winterization, and the fifteen tools you actually need.Part III — Riding strong after 50, 60 and 70The part nobody else writes honestly. What actually changes and what doesn't. How to choose a bike your body agrees with. The ergonomic changes that buy you another decade. Skills, fatigue, and an honest self-assessment you can run once a year. And the trike question, answered without sentiment.Part IV — Harley-Davidson, decodedEvery engine generation from the Flathead to the Revolution Max, with a one-line verdict on each. Which ones earned their reputation and which earned their nicknames. The cam chain tensioner years explained plainly. The five model-year boundaries worth memorizing.Part V — The Japanese legendsWhy a forty-year-old Honda in a shed somewhere is still running. Honda, Yamaha, Suzuki and Kawasaki, model by model, with parts availability assessed honestly.Part VI — The take-with-you sheetsTen checklists built to be used rather than read. The 10-minute inspection. The seller question sheet. The maintenance wall chart. The Harley engine cheat sheet. The Japanese reliability grid. Print them, or open them on your phone while you are standing in front of a bike.WHAT THIS IS NOTIt is not a factory service manual and it is not a substitute for one. Where this book and your manual disagree, your manual wins.There is no "always wear a helmet" padding aimed at people who have been wearing one since before it was required. No chapter explaining what a clutch is. And no brand religion — where a Harley engine was a mistake, it says so. Where a Japanese bike was a disappointment, it says that too.FORMATPDF, 109 pages.
