mate, i guess there is some people doesn't like motogp17 bike behavior.
for me VRTG is very realistic.
so i suggest you to download VRTG/motogp16 physic mods.
just take a look the mod on motogp16 download section, but take only .bml file on the physic folder, i mean download the data.mix, extract it, then copy the .bml files you wanted, then combine on your motogp17 mods.
i've use my lean angle mods on VRTG for motgp17, now the game is much better.
