chain for 3 inch extension

130 links is what you need to buy. just put one on my new 3 inch over JMC arm.

johns (question)

Hi buddy,

I have been trying to find someone who has a JMC swing arm for the 12. I am in the process of ordering one so I would like some feed back from you. How is the fit? Do you have bottom or top brace? , Polished or unpolished?. Would you reccomend them?

Thanks

jmc arm

I ordered a polished bottom braced JMC with the short adjusters. The arm was delivered to me 4 weeks after order was placed, exactly as promised. The price at exchange rate when shipped was about $750.00 including freight and duty. The quality is top notch. The arm installed perfectly with no problems. The rear wheel fits with the spacers provided.
The only things I had to provide were a new 130 link chain, and a 3 inch over brake line which I ordered from Muzzy. Muzzy keeps the brake lines in stock and like everything else they have it fits. The JMC comes with mounts for the stock chainguard bolt spacing (the two outside bolts) and I reused mine. The JMC does not have tapped holes on the top for the brake hose eylets. I reused the rear brake hose eylet (part# 92171-1162) and ordered a second one. one eylet installed at the back in the stock location and the 2nd one midway on the rail after tapping two 6mm holes. I requested JMC provide fittings for spool pieces so I could use a rear stand and they provided them. I can't tell from they're website if theses are standard so you better request them if you want them. The only possible problem I see with this arm is that the peg JMC uses on the inside right rail to anchor the rear caliper holder is not far enough back to hold the caliper holder if you want to run the chain adjusters all the way back. Lorcan had this problem with the long adjuster slots on his JMC. It is not a problem for me since I run my axle in the middle of the slots. To sumarize I have no problems, fits perfectly, looks great, fair price.

correction

zxkimmo you actually need 126 links to put the adjusters in the middle of a standard lenght adjustment slot on a 3 inch over arm. i ordered a 130 link chain because the replacement chain i ordered came in either 120 or 130 links. obviously you have to cut to fit.
