Even with equal displacement rules I’m certain most, if not all competitive guys would still choose the 4 stroke
You are correct with that.
As, 3 of the Japanese brands have Nothing but 4ts, and Yamaha have a pair of 2005 /2006 model 2ts they sell enough of, without the need to promote them through racing at the highest levels.
The KTM (now) Triad? - they've a lot of 4 strokes to sell, with no need to push the 2ts. 2ts that basically subsidized , through the high profits on the 2ts, their 4ts of all types - Dirt and Road - development over many, many years.
After using the same 2 base 2t engine modules: the 125/200 until about 2015/16 and 250/300, until 2017, with just the minimal changes in the engines' basic design - you can fit a 380 crank in an up to '16 250 / 300 case, with a bit of machining on one crank end - then, finally, the 2, completely new engine modules. It was a fantastic business model, so helped by the Japanese factories basically leaving a still substantial part of the market to them.
KTM, KTHusky, KTGeeGee and Yamaha would probably offer little support to riders / teams that chose to race with their 2ts, in the main series.
Heck, last time I worked in a KTM shop, the 'shop deals' offered by them for the stores race efforts, was far better on a 4t. In Australia, the 2ts are often more expensive than the equivalent capacity 4t eg: a 350 EXC-F is $14295 rrp, a 300 EXC TPI is $14695 rrp. A bloody TPI 2t, is still cheaper to make than a 4t. And, a SX250 2t, I think is more expensive than and SXF 250 here. Though, that may be just down to how KTM Australia bleeds Orange owners for all they can.......
Sherco / TM / Beta - well, they are not allowed to race in the US premier series, at all - be they 2t or 4t.
So yes, back to your point, you'd see the vast, vast majority of Privateer Riders and Teams, and , of course, the Factory Teams, on Four Strokes, still.
But, that there would be far less 2ts than 4ts out there, is not a valid reason to not let them be out there, with the same capacity limits as 4ts, in their classes.
125 class, 250 class, and, a 450 class. As despite my being a 500 2t owner, I don't think old 500 engines in later model chassis should be out there in highest level racing, and I certainly don't think a bloody 2t should have a capacity advantage given to them. I'd love to see a modern, up to 450 be developed, though, I doubt it will ever happen.
For Zod's sake DC, (and Luongo The Drongo) these piss poor, pathetic sheltered workshop / handicap class racing rules, need to be done away with. They should have been jettisoned a decade and a half ago.
