Here's some pics of my custom Ruckus, "Project Arrgyle". 232cc, water cooled, oil cooled, 4v single piston. Est 21-23hp range, 180lbs wet. Only stock parts are the battery box and front frame. Terrifyingly fun, highly recommended.

Makes me think about the bone-stock Tomos Bullet I drove in college. 50cc, pedal start, no turn signals... Man, that bike was a piece of ****.

But it never let me down.

 

I know the style of that bike. It's a classic. For a 50cc, I always tell people, "You'll never have as much fun going so slow."
