These early KTM motors had 297 cc displacement with 72 mm x 73 mm bore/stroke. Still the 300 hadn't reached its full potential. The bike was also offered as the 300 DMX, a California desert version. Back then the 300 had torque at low revs. It still has torque at low revs, but all that evolving has turned the 297cc engine into a more motocross-style powerplant with a BFM and a top-end that tends to drop off at the extreme end of the rev range, although experts are the only ones likely to complain about that.
