I think Yamaha products are pretty cool! What do you think about them?
I have never used a Yamaha product actually, but I know they make musical instruments.
Now that I think about it, they do. They are pretty diverse with their products but I think that they are overall recreational.
I know they have a 125 cc street bike with a single cylinder and two-strokes that's modeled after the DKW RT125.
It's pretty cool. Do you know the strongest street bike?

Response: Sure, the strongest motorcycle model is the Lighting bike.
