It’s been a while since we considered comparing a modern 450 four-stroke to a classic CR500 two-stroke, but the topic remains as fascinating as ever. Twenty years ago, nothing was more violent than a 500cc two-stroke. It was widely believed that they possessed such power that no one could ride them, and that was their downfall. Today we have 450 four-strokes producing similar peak power on the dyno. Does this mean that the modern 450 is also coming to an end? Join us as we compare the 2023 Honda CRF450R to the Pro-Circuit CR500R in a CR250R aluminum frame that was built for professional racing more than 10 years ago.
