What is the best pipe and silencer for an 02 cr125? My dealer told me procircuit pipe and procircuit shorty silencer. But Dirt Bike magazing says to get sst pipe and sst shorty silencer
I can't tell you what pipe is best but i did test a PC pipe with a shorty. There was no change in the bottom end compared to the stocker,but the mid was crisper and sharper feeling with a stronger pull to top end. It's a good set up for a mid to upper level rider,but like i said it didn't hurt or help the bottom end.
I run a Pro Circuit with the shorty muffler and it improves the CR250 noticably. better everywhere without losing the smoothness. I am far too beefy for a 125, however one of my buddies runs the same setup on his CR125 and is very happy with it. He also went with Boyesen soft reeds in the stock cage, I'd ask him how much difference it made, but I can never catch him!!
