What do you think of harley-davidson motorcycles?
Well I have not been around since they were founded in 1903, but since they seem to be a good company.
Have you ever ridden a motorcycle before? I have a motorcycle, but it's not a harley-davidson.
No, I have never ridden one. But I do love riding bicycles. The motorcycle originally came from bicycles.
That's so cool. I didn't know that. What kind of bicycle do you ride? 
Well I just have a street bike, but I would love to try mountain biking which focuses on off-road and rough terrain.
It sounds hard to do mountain biking, but I think I would still try it. My friend likes to mountain bike in Colorado.
It does sound hard, but there is downhill mountain biking. You wouldn't have to pedal uphill, but there are jumps, drops, rock gardens and other things to contend with.
