We have multiple Honda Xr 400s and a couple Honda crf 450 f. The XR models ended in 2004 but in my opinion were some of the best trail bikes ever made. The Crfs are good bikes but if you aren’t interesting in racing make sure to go with the f model because the r will be geared just a little bit differently and make it slightly more difficult to ride on the trails. It is a great hobby that has kept my family close.
I bought my first bike when I was 16 and then went on my mission a couple years later and came home to my dad and brothers all having bikes.
