that was definitely mph! Did you notice what gear he was in and what is rpms were? If he was in top gear and at like 10k, he would be at like 260kph, unless he had some HUGE sprocket on the rear; in which case he would be wheeling the entire ride. Also notice his lean angle going around that turn at like 50mph; it seems to match the amount of lean that I am at going at a turn around that fast/
