My first motorcyle at 16 years old been a suzuki gr650,paid 200$,I changed tired over the years,oil filter plug,chain....bike is almost in the same condition,put 100000 km in 11 year on it,not so bad for 200$,stored the bike for my future kid and I run a gl1500.
I think the secret is not which model,but more how the bike been treated and maintened over the years
