BigRed350x Posted April 4, 2012 Report Share Posted April 4, 2012 I count 8 different suspension mounting points held in single shear, and suspension load members carrying a point load to frame members that are in tension. EEeek! I know they race these frames in the baja & all that, but there are some huge structural no-no's on that frame. I wouldn't ride it, even knowing its held up fine through quite a few baja races. Structural Dynamics classes in college ruined a lot of fun stuff for me. lol Quote Link to comment Share on other sites More sharing options...

WINDYCITYJOHN400 Posted April 4, 2012 Report Share Posted April 4, 2012 Foot pegs are single shear mount style. So are almost all the lonestar hill shooter and drag chassis. Or any chassis that uses heims for A-arm mounts. On this chassis, the weight load is focused on the shocks and the outer end of the A-arms. The front to back shear load on the inner A-arms mounts is lessened by the large triangulation distance between the front A-arm mount and the rear. I get more freaked out by the use of heims than that chassis design. You can worry about single shear heims at the mounting points all day....but you still have the heims at the ball joint location. You want to see a wicked chassis....do a search for Lew Jr's version of that chassis design. He calls it his Trophy Truck chassis. Baddest ass bike I've ever seen.

So Cal Suspension Posted April 4, 2012 Report Share Posted April 4, 2012 I call the Sundahl frames the I-beam abortion. It's like an older i-beam ford pickup raped an a-arm ford pickup, and had an ugly ass baby. Have you guys ever seen how these things articulate? Like shit, that's how. Camber gets all fucked up through the articulation. +/- 8 degrees I've seen. They are so unstable that you wouldn't be able to corner for shit. They're fast in straight line whoops, though. Center mounted a-arms would pull more USABLE travel than that sundahl abortion. Quote Link to comment Share on other sites More sharing options...

You can worry about single shear heims at the mounting points all day....but you still have the heims at the ball joint location. Can't tell the difference between chromoly teflon heims and cheapo heims, can you? JMX12T's have a radial load rating of over 28,000lbs. Edit: Just looked at the pictures again. I was wrong, the heims used at the frame location appear to be RSMX10T's. They have the larger shaft. In that case, the RSMX10T's have a radial load rating of over 40,000lbs. The ones on the spindles are definitely JMX heims, though. Which seems backwards, he should have used the bigger heims on the spindles, but if he exceeds 28,000lbs on those heims, that entire frame would crumble before the heims even THOUGHT about breaking.

DallasGDub Posted April 4, 2012 Report Share Posted April 4, 2012 I like it......I bet it floats like a caddy. BUT....I would take cam's Outlaw banshee in the for sale section before this one. or that 611 would do as well. Quote Link to comment Share on other sites More sharing options...

zach45 Posted April 4, 2012 Report Share Posted April 4, 2012 I like Matt's idea of a yfzr front end.. Once I get a 220 in my garage Im going to give the "frame chop" a whirl Quote Link to comment Share on other sites More sharing options...

I just cringe every time I see the god awful price LSR charges for their outlaw frame, when really, it's nothing out of the ordinary. I've seen better designs built in garages... 250r's are pretty sweet though. I bet it would corner better than a sundahl, but they don't even have close to the same wheel travel.
