1) When people talk about two strokes, they talk about the very good power to weight, size and complexity ratio. If your objective in design needs those things, then you've found the better engine.
2) When people talk about four strokes, they talk about reliability, economy and superior emissions adherence. If your objective in design needs in those things, then you've found the better engine.
3) Making a four stroke engine bigger until you gain an edge in power over a two stroke does not make it a better engine for power, just like making a two stroke smaller to make it use less fuel doesn't make it a better engine for fuel economy and emissions.
The 2stroke engine despite today's campaigns for pro 4stroke consumerism is a lighter weight, less complicated and by far, cheaper platform to build a racing chassis around. In addition, CC for CC 2strokes make more power than 4strokes typically by about 33% AND with a more simple design.
Although All250R 2-Stroke Motorsports can be considered a Honda TRX250R roots effort, All250R welcomes and pursues all useful content related to the preservation, development and usage of all 2stroke engines. Other related usages such as the ATC, CR motorcycle, Suzuki quadracer, Banshee and next generation DI platforms. The 2stroke platform is one of the most popular, usable and flexible small racing and utility engines ever created. Superiority through simplicity.
