This just reminds me of why I bought a dual sport.
For me it was riding on the back of my cousins Honda CT70 when I was 4-5 years old. My aunt and uncle had 70 acre farm and he would ride be all over the place on that. I can still see my parents cringe at the sight... they knew I was hooked.
Then my buddy in High School had a bright red Honda Elsinore CR250... and his Dad had a Honda XL500. A dirt bike with lights, that looks interesting... I think the Elsinore that my buddy had was the last year before Pro-Link came out and the XL had the Pro-Link. Very cool. From that point on I knew someday I would own a Dual-Sport bike.
In college I owned a couple of street bikes. A Honda CB650 and a Nighthawk. I think I bought the first bike a saw rather than being patient and buying a dual-sport. Sold those bikes and almost bought an NX250.
Last year I finally bought the dual-sport. I can't beleive I waited so long. I really enjoy my WR^2. So much so my wife may ask me the same question your mother asked your father...I sure hope I don't have to make that decision.
I don't know your riding experience, but I would highly recommend the MSF basic rider course and the dirt bike school.
Whatever you buy, just make sure you have the cash to pay for it. If you have the cash pull the trigger!
