the gearing in both quads is pretty much the same i think. And ever quad i have ridden(yfz,ltr,mxr,kfx,525irs,500irs)they all have short first gears, thats why when you race on dirt you start in 2nd, ive never ridden a trx so i cant compare to that, but since my outlaw has the same engine as the ktm i think they have similar gearing, and if thats the case first gear is short, i use second in trails and at low speeds and it is no problem. hope that helped?
