One time I saw a post of a player here who tried to jump off the canyon using the mordred caliburn and reaching up to 450 km/h (probably without the speedometer fix mod) and failed. So, I tuned my Muramasa using the performance mod shop and tried to jump. The first two attempts were with kusanagi and nazare racer, both tuned, but I didn't managed finish the jump and had to eject from the bike to achieve it at the end of the stunt. On the 3rd attempt, first time using Muramasa, I recorded this.
