I have been trying to copy the physics of the yzf-r1 to the sm_derbi_senda, i followed a yt tutorial but it was for cars, and a couple things are messed up was wondering if you could help me fix the issues im having. the rear wheel isnt locked to the bike and turns when you turn, i think this is because the bike trying to lean but the wheel is able to move so it does that instead but honestly have no clue any help would be appreiciated
