none of the pipes give better low end for the CR 125, its a 125 what are you doing down thier in the rpm's anyways. To get the most out of the CR you should be screaming the piss out of it. Most pipes just give it more Mid which it all ready has a lot of and alittle more of top with alittle bit more rev. I think a vforce reed block would be better for more low end and get the 2000 model its the best one for that bike cause it has a larger intake. If you switch out the rubber piece from the carb to the reed block with one for a '01 since it's shorter will give it a tiny bit more low end and I mean very little bit you probably won't feel it. If your still running stock gearing gear it taller two teeth is all the higher you should go. A thinner base gasket would work but would require you run like race gas (you guys think two head gaskets might allow it to not detonate on pump gas?) Get an after market piston cause the stock one has to much clearance it will bump up the compression ratio alittle bit allows the bike to come on the pipe sooner. These mods will only marginally give you what you want but its better than stock definetly. If you want more your gonna have to port it. Most people go the opposite way with the CR's most people want more top end.

MXPIMP is exactly correct-the 02 is almost impossible to get good low end from-the only thing that might work is eric gorr lowers the cylinder alot and stuffs the rear transfers with epoxy-the lowering of the cylinder on its own doesnt help much-you can gain maybe 0.5hp on the bottom but loose 1.5hp from the top.Sorry but the 02Cr125 isnt the bike if you want bottom end-any other brand is probably better for more bottom.The CR can be tuned for a screaming top end however.Like MXPIMP said the bigger rear sprocket is the best bolt on.
