Been a while since I did one of these, but I recently encountered a scooter and I loved how the passenger footpegs are tucked away when not in use. What two-wheeler is this?

Based on the logo on the tank of this bike, can you determine what we’re looking at?

You know the deal. Here’s a bike. Guess what it is!

Contributor Tim Huber just sent me a link to a BBC Documentary about Japanese bullet trains. Great, you say, but what does that have to do about motorcycles?

10/8 Update: Sorry for the delay – Alex Tyrol was the first to identify that this is indeed a Sertum.

He just sent me a picture of an interesting motorcycle he saw and I want to see who can identify it first! I’ve (poorly) photoshopped out some obvious details, …

Here’s a frame. What bike does it belong to?

Congratulations to Facebook commenter Bill Beebe, who was the first person to correctly guess that this was a Moto Rumi!
