On another forum the conversation came up about '98 (or older) RS250 and all the myths about insane horsepower of a 2 stroke. Quick search gave me a spec of 92 max hp on the last RS250 made which was 10 years later, so my guess a '98 RS would be 90hp at the crank at best?

My RG500 is about 100hp at the wheel so I speculated that it will eat any RS in a straight line, even with extra weight that it carries, as they say here in the colonies, "No replacement for displacement"
Someone came back with a 120 hp number for 250GP bikes and I began to wonder what did they run in 250? Always thought they were "production" RS250 with some extra special parts? Please educate me. Thanks
