สิ่งที่ผู้ซื้อควรรู้
Bulletproof air-cooled single
The YBR 125G uses Yamaha's long-running 124cc SOHC two-valve air-cooled engine, a design proven over two decades that routinely passes 50,000 km on nothing more than regular oil changes and valve-clearance checks. Parts are cheap and almost any roadside mechanic can work on it.
Watch chain, sprockets, electrics
Common gripes are rapid rear sprocket and chain wear if lubrication is neglected, plus occasional charging/rectifier and switchgear niggles on higher-mileage examples. Also check the front fork seals and the spoked wheels for rust and loose spokes, since the G is the semi-trail variant with longer-travel suspension.
Strong, steady resale
Commuter 125s with the Yamaha badge hold value better than Chinese-built rivals, and the YBR's fuel economy of roughly 40–45 km/l keeps demand high in the used market. Expect to recover a solid share of your purchase price after a few years, provided the service book is stamped and the frame shows no crash repairs.
