Ultimately it's down to finance and what you ask of an outfit. Urals and Valks have their attributes, but the Honda is made for getting on and riding, again and again. As said previously Ural's are old school and require TLC to give of their best. Plus, and it's a big plus, the Honda will haul anything along, you should see what some have to drag around here in the UK and Europe. Whatever the sidecar it's no problem, it's almost as if the Big H made their flat sixes specifically for sidecar work. Bottom line for me would when carrying a loved one around would be reliability, unquestionable performance and comfort. However, whatever you choose, you and your Dad ENJOY.
