you stated it was regularly serviced at a dealership. that should cover everything.
what would I look at? EVERYTHING. EVERYTHING on the maintenance schedule.
throttle operation, kickstand spring, wheels/spokes, tire pressure and condition. drive belt condition and adjustment, brake condition. oil and filter change. primary and transmission lube change. primary chain adjustment, battery voltage, charging system voltage, operation of all lights and signals, critical fastener torque, clutch and clutch cable lube and adjustment. air filter service, all lines and fittings, spark plugs, air suspension settings, test ride. everything, because your life depends on it.
just so we're on the same page........if I had just bought that bike.......I would check EVERYTHING.
after that, I would adhere to the maintenance schedule.
let me know if you need more help.
if not, please leave a POSITIVE RATING.
