Yamaha E01 Concept. Futuristic in appearance, the Yamaha E01 concept scooter is designed to work in the performance range of 125cc four-stroke motors. While it appears to have Bridgestone slicks, it’s intended for urban duty. Of course, those large disc brakes and the beefy shock do indicate that the Yamaha E01 will have strong performance capabilities. There is plenty of room for a battery, and it has a fast-charge capability. We haven’t sat on it, but that colossal seat on the E01 looks to be seriously comfortable.Yamaha E02 Concept. This is another scooter that will be competing against 50cc four-strokes. We like the IRC tires, as well as the innovative final drive to the rear wheel. Yamaha is mum on that right now, so we will have to wait and see. The Yamaha E02 Concept has traditional forks and a front disc brake along with a striking front wheel. It’s a sleek design that is also practical. The battery can be hot-swapped when necessary.The theme at Yamaha Motor’s booth at the Tokyo Motor Show was “There Is Greater Joy Yet to Come—ART for Human Possibilities.” These peeks into the future are intriguing and inspirational.
