Do you know what is the ONLY racing series that allows fair racing in regards to cc per cc? I will tell you, it is the Erzberg enduro series, this is the only one. The other ones: the CMC, the AMA, the FIM, et al, all force 2 strokes to compete against 4 strokes twice the size. Oh and by the way, the KTM 250 SX makes as much horsepower as the best 450F and nearly as much torque with nearly 1/2 the engine size, not enough? I continue.. anyway, the Erzberg is the toughest, most brutal race on the planet and, guess what? This "fair" race forces riders to ride the best, lightest, most potent bike and with over 800 entries this year, how many 4 strokes finished in the top 10? NONE! How many finished in the top 20? NONE! How many even finished? NONE! So go ahead and praise the engine that can't even finish the Erzberg, it makes you look... well, like a flat-earther. Don't buy the hype, it is only to sell 4 stroke parts to the "followers!" Are you one of them? I know I sure am not.
