There's a guy in my bike club Who has a 250 rebel. It's his only vehicle, and he rides it no matter what. Rain, snow, freezing cold, a real biker in my book. He just loves to ride. He recently had a stroke, and is not able to get his liscence back. He wants to continue to be part of the group, and has asked if anyone would consider letting him ride two up. A few of us stepped up, and offered our services, figuring he could ride on the biggest bike available. I guess my question is " what are the dangers of letting someone ride two up, who may not be physically 100%."
