Instead of being stupid and asking if I should get a 999R or a 999S (I have seen some fools ask questions kinda like that ) for my first bike, I would rather be logical about my investments. I would like to know how reliable old school bikes are (1971-1989 H-D, Honda, Suzuki, Kawasaki, Yamaha), and witch companies tend to make longer lasting bikes. Are bikes, in general, easy to work on by yourself? How often does the oil need to be changed? What is the average cost for upkeep on the bike per year (not including gas)? What is a rough estimate on insurance for a 19 y/o for a 15+y/o bike? If you could answer even a few of these questions I would really appreciate it!!
