My ride: 2011 BMW R1200RT.
>>I just don’t see Yamahas on the side of road broken down.
Actually I rarely see any cruisers on the side of the road broken down. I’ve only seen (and stopped to help) supersport or liter-bike riders. Almost all were strange electical problems or FI problems.
My Harley Sportster is pretty darn reliable, and the maintenance is very light—no valve adjustments, no chain lubing/adjusting. Just change the fluids, check the plugs, and of course check all the fasteners.
But so is my Kawasaki W650. I’ve checked the valves and they have never needed adjustment, and lubing the chain is not a big deal with the center stand.
