I just love motorcycles, I ride them for a living and I'm pretty much an expert on them, What would you like to know about them? 
What's the best kind of motorcycle to get for someone that's never ridden one before?
Well Harley Davidsons are popular, They even have handy owner clubs and events worldwide and even a company-sponsored brand-focused museum.
Yeah, Harley Davidson bikes always seemed kind of cool to me. Is there anything else you can tell me about them?
Well Harley Davidson is an American motorcycle manufacturer, founded in the state of Milwaukee, Wisconsin way back in 1903. So they have a ton of experience. 
Sounds good. I might have to look into them a little more. Is there any advice you can give me when it comes to riding a motorcycle?
Well there are three types of motorcycles: street, off-road, and dual purpose. But if your starting out go with a street bike and go slow at first. 
Yeah, I've always liked the look of street bikes. Aren't they usually faster than the other types?
They are in fact sports bikes are pretty much optimized for speed, acceleration, braking, and cornering on roads, but usually at the expense of comfort and fuel economy by comparison with other motorcycles.
Oh ok. Which kind of bike has the best fuel economy?
