I think all scooters and motorcycles should have both kickstarters and centerstands, though it is hard to imagine a kickstarter on a Goldwing or a GSXR. One of the big issues I have with motorcycles, is many still have tube type tires from the 1940s (some combined with ABS brakes!!!) and no centerstand, so you have no way to fix a flat tire. I gave the Suzuki TU250X a long hard look, but just decided it wasn't worth the risk. A flat tire out in the middle of the AZ desert in 115 degree temps, and out of cell phone range could be more than just inconvenient, it could be fatal. If it had a centerstand, even an optional one like the Honda Nighthawk 250, I would have bought it.
