Modding a bike, that's usually rider preference.
It's all about what
you like.
Myself, I keep them kinda stock, and set them up for the backroads.
I like the twisties, and rarely am more than 200 miles from home.
For this, look up "cafe'" racers.
Some guys like the long haul, visiting different cities and states.
For this, look up cruisers or touring bikes.
They're big on seat comfort, storage for gear and some kind of fairing or windshiled.
A totally restored, but good running bike in original form is cool also.
It's what you want.
As for good memories, or things to do with them, yeah, I work on them,
but for me, it's about the ride really.
I find myself thinking about the longer hauls lately, got some friends in far off places
I havn;t seen in ages. We'll see.
But, for now, this is where one guy is.........
