Which aftermarket aluminum swingarm works best for 79-80 CR125 and CR250? |

For the '78-'80 CR250R's, an original Fox Factory arm in good usable condition or a repro Mugen ME360 arm. For the '79 CR125R, an Al Baker works copy or the real thing. |

I have read that both of these swing arms produce a rising rate geometry that is preferred over the stock falling rate. I have a DG arm which is basically stock geometry plus 1" longer for more straight line stability. The price differential between the two designs can be up to $500 so take your pick or more likely buy whatever comes up first and upgrade later if you can afford it. Novation Racing is offering a new rising rate swing arm but it uses shorter than stock shocks which might be a problem unless you planned to sell on what you have now and buy some new ones. |

Red, Is the Novation swingarm for CR 250 or 125? Does anyone make a replica of the Baker or Mugen arms? I've seen a replica of the 80 CR125 Pro Fab arm. What size shocks did the 80 CR125 use? J |

Check the web site at http://www.novationracing.com/index_page3.htm. I seem to remember CR125R and CR250R being listed. The Red Racer board months ago had a thread about a guy who was going to build replica Mugen arms, but nought came of it. |

I went to Novation website, but they don't have any pics of the swingarms. I'm waiting for a reply about which type of replica they are. I saw on another forum that someone had posted that 78-80 CR250 and 79 CR125 swingarms were the same. I know the shock length is the same, but they all 4 have different part numbers. Could an aftermarket stock length CR250 swingarm work on a Cr125? J |
