Most of them looks like Honda RS125R bikes but with new engine or am i totally mistaken?
yes you are almost right. S80 machine Regulation is only Displacement and safety's one.
many rider choise motocrosser Engine and tuning it and mount to H RS125R chassis. ofcourse, some rider use YZ and TZ one. and some rider make original chassis!
speed is almost same to GPB mods. topspeed is about 165km/h at Tsukuba backstraight (if jetting and engine condition is perfect)
