So say they allowed you to run 250s in the 250 class...etc and even it up. 2 strokes are so simple what can you really do that they havent? The 4 strokes jusssst started adding finger followers allowing for much more aggressive cams than weve seen so far. You can have single cams like the ktm with basically forked roller rocker arms from a central cam- which Idk how this makes so much power as the simplest head, but it works and its light. Then the Crf450r has the single cam over the intake with a rocker arm going to the exhaust valves. Then you go all the way to the 19’ Kx450 which uses superbike tech with roller rockers now on both cams like the crf250r also uses now which is as high tech a dohc cam setup as it gets and the most high tech in each respective class from those 2 engines.
For 2 strokes you can do direct injection, which they say makes it ride more like a 4 stroke which imo if they want to be competitive thats not a bad thing. Then what an electronic power valve? Maybe have a couple... Maybe better reed valve systems which i dont think direct injected would even need Im not sure. Then obviously elec start. Ive heard theres things they can do with pistons, but what more can you really unlock in an engine with no cams? Anyone know any new 2 stroke tech that would be going into these bikes if they were still used?
