I've been following this thread thinking that some of you are a little bit bitten, then I counted my own. In 7 years since returning to riding, I've had 12 bikes, with 3 in the stable now.
TTR225, KLR650, NC700X, VStar1300, generic pit bike, Reflex 250, XR80, 08 XT250, Super Tenere, 13 XT250, G310GS, Wee Strom
Reasons I've sold bikes include bad ergonomics for me, and wife no longer rides (no need for 2-up ability). Reasons I chose the new ones are: I get fixated on the new shiny, my riding style changes.
Most importantly, and in line with the "getting rich" theme here, riding has been an incredible bond with my youngest, who's now going off to college. So many memories together are secured, and I imagine it will be a strong excuse to stay close in the future as well. I've made some good friends here too. Cheers to you all.
