Try to mod physics lately. Turn out all we get is reduced realism. Here's what I edit: \DATA\PHYSICS\VEHICLES\PLAYERDATA\125CC_2_STROKE\125_YAMAHA_TZ125_1997.BML I use TZ 125 for example. On vehicle element, there is realism value. On vanilla, we get 0.7. After I buffed up to 1. Damn, the effect so realistic! Bike is wobble on high speed. Too much front brake? You'll lost traction. My instinct, this game engine is a gem. Just waiting for modder to unleash the kraken. Try it for Yourself man.
