Are ktm exc 125 and 250 frames the same?

Answer 1

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.
