I am a couple inches taller and weigh about 15 lbs more than he does, so I'm not exactly an ideal passenger. On that bike it might work, since the bike is so heavy itself, and the passenger area is spacious. Maybe we'll try it sometime but it's not a particular goal. With troubles I have been having with my foot, I am not going to be carrying passengers anytime soon. I always found it exhausting and scary to carry passengers anyway, even when I was not so fragile, so I'm glad to just exempt myself from that whole deal. The moments when the passenger climbs on or off, are the worst moments in motorcycling, IMHO. I don't need it.
On the Ural we switch off all the time, but carrying passengers of any weight and agility level in a sidecar is easy.
