i only started trials from motorbike trials and watching Danny Mac, he has changed trials around and got more people into street trials, which is goo, but me and my mates only ride street because it is close by and it has natural riding in our town, (rocks and walls) but i would prefer natural riding because its more related to motor trials, its not that simple going out in the middle of know where with no car as im 16, its easy just to ride into town and get on the train to where ever. thats why i bought a bike that is street and natural, because i simply love them both.
