This is the bike for those of you who enjoy making fun of the R-bike-people. It´s a king of acceleration, from about 2500 rpm it has the power to accelerate so fast, you´ll think it´s on NOS. It´s kindof nervous though, meaning it responds dramatically to minor movements of your right arm, so handle with care. Do not jump on an X-11 and accalerate 100%, you´ll either fall off or end up on your back with the monstrous bike on top of you...
