If you want to totally ignore a bike and just beat on it relentlessly without proper care, buy a Buell XB.
The combination of ancient/proven/refined engine architecture, and modern but simple (and jailbroken
) electronics, with almost no maintenance requirements, make it the perfect ride to circumnavigate the globe.
You'll never have a clutch line leak or the valves adjusted, your sprockets will never wear out and neither will your chain, they're not 13:1 so they'll eat any crappy gas, and the radiator won't get damaged in a crash. Your ABS module won't send you in limp home, and neither will your traction control. Need a part? You'll find the same ancillary stuff on 25 years of other brands of bikes and even scooters.
You, or someone else can fix anything
with a small amount of knowledge and basic tools. If your 2019 BMW GS breaks down in ...-istan, you'll need a tow, the dealer, and a fat checkbook.
IMO if your Buell ain't runnin' right, it's YOUR fault.
