    No report on quality yet, but it's less than 1/3 the price of a custom line, didn't have any trouble bleeding it either. Recommend using the stock banjo bolts.

    No its not . A standard length line from Galfer is $26.00 and they may extend it to the correct length for only 5 or 10 bucks . The line you bought is 2" too long.

    They also have different colors.

    Well you could have known before you bought the other one if you had simply asked . That's the whole purpose of this particular forum.

    Nobody saw it then . If you want answers, it is helpful to make clear specific questions that are not combined with a lot of other info where it can be lost and you will get them.

    No, the price difference isn't a big deal but its sometimes hard to find a place tor 2 extra inches of brake line . plus you could have goren a colored one if you wanted.

    contrary to what you have inferred at times, there really isn't anything that someone doesn't know on this site and they are all very happy to help people that are courteous to them.

    Spiegler offers custom lengths, colors (fittings and lines) banjo angles add the banjo fittings can be rotated 360 degrees for a perfect fit. They are also DOT and TUV approved and guaranteed for life.

    That shits expensive
    It sucks to get old

    I think the chain slap is going to be bad...

    Now, if this swingarm bends, or if I just decide to build a better one, would I be better off designing one from say 1" .120 wall DOM and incorporating a truss into my design, or just use 1.5 .188-.25 wall DOM, with the same general design used here, and a new carrier made. I know this design is easier to make and I could knock it out in a couple hours. The other option I thought about is designing and fabricating one out of plate steel.

    First impression; well I can actually slide the damn thing now. Wheel spacers and some ITP hole shots and it should be pretty fun to ride

    Second swingarm, thinking I'm going down in length to a +6, which should put me ~20", or the length of a modern trx450r.

    Does anyone think it would be worth my time modifying the frame for a 450r linkage? Only downside I can see without measuring would be that the chain tension is adjusted via the front pivots, which would move the shock angle a few degrees when adjusting the chain.

    I have (very) basic drawings for a swinger made out of flat plate, either cut by me with a plasma or sourced out. I still have to find a shop to make me pivots and a new carrier (any takers?).

    I think if I buy a set of inverted forks + triples on eBay, I can take them to a competent machine shop and have them build billet triples at the width I want out of aluminum, shouldn't be crazy expensive aluminum is not as time consuming to mill. Or I will contact Jason hall to see if he's going to be building more any time soon. Idk what most people run but I think I can get a 200x hub and brake setup to work.

    That thing is slick? What is the swingarm made out of? First gens didn't have a linkage, I think modifying one to work would be less work than spring and valving changes on a shock that isn't even adjustable.

    Is there anyone with a 450r linkage setup that can take some measurements for me? I picked up a 450r shock on ebay for $35 total, couldn't pass it up. Judging from pictures I thought it was a lot shorter, nope just beef.

    I have very basic drawings for v2 atm. Tried CAD but I didn't have the best of luck with it. Going to make it out of 3/16" flat plate, cut with a plasma. Carrier machined out of DOM. Should be pretty beef.

    Does anyone happen to know the inside width of the carrier bearings? Need to have a carrier machined to build this swingarm, before I put these holeshots on.
