I read a through a few of the comments. I feel for you man and wasn't being disrespectful at all. I was giving you shit. I grew up in a similar boat. Had to ride my dads 01 CR250 whenever I could and later had to share it with my other two brothers when my dad got a 450.
We rode the hell out of that thing and even seized the piston after we all took turns on it all day.
Earning your own stuff is great. You have a sense of accomplishment as well as learn to take care of shit.
I know a few kids out at the local track riding 2016 250F's and 450's (I ride an old 03 Cr250, I loved my dads so much I had to get my own) but they crash weekly and don't even care. Just load up the bikes and go to the parts store to purchase 100-200 in broken parts weekly. I couldn't afford to do the sport if I was that careless as I'm sure most of us wouldn't.
