I just upgraded to the lite from the og b5m which i had approx 8 months of wheel time with . I basically put the same setup on the lite but upgraded the lite with ceramic tranny bearings and schelle slipper lockout and machined pistons x seals ect . Another thing i was running the trackstar with the og but have got the fantom works short stack in my new lite . First race meet on the lite and i am quite impressed , went .1 quicker on fast lap ( was hoping for a little more ) and pretty close to my best 5 min , could have gone quicker but ran into traffic in a2 and a3 . Very happy with the lite and sure in no time will get it feeling just as planted and confident as the my og b5m
