Ei Sekigahara's motorcycle from the future. Its name is Shikishima SXR-NR.
It uses a powerful bearingless motor manufactured by Shikishima Industries and reaches a top speed of 450 km∕h. Its safety features have been improved, and it can stand on its own while stopped or at low speed, preventing skidding with a jet that shoots compressed air. It even has a feature where it finds its way to the owner, thanks to the self-driving and biometric authentication system.
