An alternative to the Yamaha/Lifan V-twin 250 (which is very heavily finned for styling purposes but also add to it's ability to reject heat) is the Suzuki GZ250. Single cylinder narrowness and air cooled simplicity. Mileage is almost as good as the Yammie. And they are typically even cheaper.
I'm considering this for my Dan Gurney Alligator-inspired project.
Another one is an old KLR250, water cooled goodness but the wheels are big dualsport sized.
Yeah, long stroke motors are hard to find especially in the smaller cc capacities. The Yamaha design even just feels better than most 250s because of the smooth, solid torque.
