I spent a good amount of time pulling together specs for various MiniGP / SuperMoto bikes (i.e., smaller motorcycles). I think seeing the numbers compared to other options out there really helps put these tiny, small, and small-ish bikes into better context. I’ve grouped them into size classes by length and then sorted them by weight. If you know of any of the missing specs, pass them on and I will update this list.
