I dont care how old the bike is, she can stroke me twice, or even 4 times, anytime.
I know I belong in the basement, err, garage
Nice old bike too, that would have been light with those bicycle tires
"Your mom is old.."
Hey 85 year old guys think she's young & HOT
But back to seriousness , I think the over 5 years & its outdated really fits the dirtbike "old" spectrum. By then your replacing plastics , if you drop it alot like I do anyway, its time for some internal work, probably change a tweaked rim.... The new is clean gone & its time to get to work on it. Ten years & its obsolete is just time to think about converting to newer suspension & EFI.
