A rear blowout is not pretty in traffic, a front one is even worse. You might get by on dry pavement for a while, but if it rains or if you need to make a sudden stop or turn or all three at once, good luck. Also, your rusty old chain might last another year, but if it doesn’t they are known to put holes in engine cases, a career-ending injury for many motorcycles. Maybe that leaky fork seal will fix itself, and maybe it will get worse and spritz oil onto your front brake. A motorcycle is not a car, people. You’re not always going to just coast to a bemused stop if something fails. Speaking of which, when you attach things to your rear seat or rack, do it so the thing can’t come off and get stuck in your rear wheel (though it is fun to watch that happen to other people).
