the swingarms are different![]()
Like I said, other than the wheels, brakes, computer and a few other things the PR4 is its own bike. Different frame, seat, suspension, swingarm, linkage, engine, etc. The PR4 is noticeably smaller sitting on it. I really like that they took the time to build to completely different bikes so they get it right. They don't just share frames across the board and you have to adapt like many manufacturers. Quality is amazing for a 5k bike.
If you just get on the PR5 and ride it feels pretty much full sized, like a 125. But if you hop on it after riding a regular bike like a KTM 350, WR250 husky or Wr125 husky it feels noticeably smaller and lower. Almost looks bigger than this YZF450 but feels much slimmer and smaller / lower when riding it.
