I have to assume you're talking about Standard Byke's 125R vs. Standard Byke's 250 Series frames, correct?
First off, the intended purpose of these two bike frames are completely different. A 125R is a racing frame (thus the "R" in "125R") while the 250 Series are Freestyle frames.
As far as "size" goes, the 125R and 250 come in five different sizes: 20", 20.5", 20.75", 21", 21.25" (250 Series only) and 21.5" (125R Series only) top tube lengths. So to answer your question: A 125R and 250 are the same size if you compare the same two sizes, but the 125R comes 1/4" longer than the longest 250.

the engine power and the seat height
The KTM 200 EXC and the SX 125 have different bottom ends, as they are designed for different purposes and engine configurations. The 200 EXC is a two-stroke enduro bike with a larger displacement and different power characteristics compared to the SX 125, which is a smaller displacement motocross bike. While some components may share similarities, the overall engine design and tuning differ significantly.
