I have a friend with that attitude. Disregarding the fact that his bike, a nice Harley Heritage Softail looks like it's on it's way to audition for the next Mad Max movie, he recently had to take it to the shop because the rear tire was bald. On the way, his fork seals let loose, soaking his pant legs. Total bill was near $600, all for minor maintenance items he'd been ignoring - or didn't even know about - for months or years.
During my bikeless year, he was kind enough to let me ride the Harley, his Legend TT and his BMW so every time I took one out, I washed it and at least checked tire pressure etc. Probably the only PM those bikes will ever get.
