It's funny that I'm constantly trying to teach my three grand daughters the difference between "wants" and "needs".
You bring up a good question that maybe we all "need" to visit ourselves.
I used to tour throughout Canada and USA on my 1854 cc bike. It would lope along doing 100kph (62mph) at 2500 rpm. You wouldn't believe how many forum members would whine about excessive engine rpm's and the absolute "need" for a sixed gear to lower said engine speed.
I currently ride mostly on my two scooters, one being 50 cc and the other is a 300. Sometimes I am happier on one vs. the other. I can see myself "needing" a middle of the road scooter between those two in the near future, but I truly understand that it's only a want and not really a "need".
