    Good call. I have seen many aftermarket SXS arms what come bent the other way to allow for extra clearance. I assumed it would be okay if braced properly but you are right, I think it’ll be a higher stress point than if the arm was straight.

    However, I put a bend in it to allow for CV clearance at full droop. If you look at the full droop CAD photo above, the CV joint would contact the lower control arm without the bend. An alternative is to have a straight control arm with a large cut out between the two lower arm heims to allow for clearance with the CV.

    Thanks!!

    I got the rear upright plates cut out and also 3D printed a jig to hold the rear upright plates while I tack it together.

    I have also started designing the rear a arms. They will be boxed arms within rectangular bungs for the rod ends. The frame mount side will use solid bushings.

    I machined the bungs out of 1.25” solid square bar and tapped them for the 1/2”-20 threads on the rod ends I have.

    The bushings are built out of an outer sleeve 1.5” DOM tubing and inner sleeve of .75” DOM tubing. I made HDPE bushings to act as the ‘wear’ part of the bushings.

    I also did a rear ended mock up using a Plywood a arm and a ready rod as an upper link. Still have proper axle plunge, no cv binding (as of now) and proper can bet numbers! It should turn out good when the a arms are built.

    I also built four threaded and drilled angle iron pieces which will get bolted to my a arm jig. I used a 3D printed template to Centre punch the location of the holes to make sure everything is centred and make sure the bushings are held at the proper height while tacking the a arms together.



    More to come! I am waiting on sheet metal for my a arms so I’m going to be re doing my throttle cable set up. Stay tuned.

    Thank you!

    My old throttle cable/linkage set up what somewhat sticky and I would like to call it sketchy now that I got rid of it. Here is something I designed the other day to have a way smoother pedal feel and a more predictable throttle pedal.

    I used 2 extended throttle cables from Amazon and I modified the ends slightly to work work the Yamaha R1 throttle body. I built a throttle cam and mounted it in a secure spot to the side of the seat. I think this should work better!








    I am working on a design for my new boxed a arms. I am going to be using 12 gauge plate for the top and bottom caps and 1/8” x 1.25” flat bar for the webbing and edges.

    I am trying to determine if the control arms will need additional bracing on the inside (like pictures below) or if I could run them hollow without additional internal webbing/bracing.

    They are 14lbs according to Solidworks with heim joints, bushings and bungs.

    Definitely need internal ribs on the bottom units. The open box will crush where the shocks attach.
    Had this issue with the first boxed set I made for the old XP900 I had.
    Not sure you need the line that parallels the X-axis of the drawing but definitely will need enforcement under the shock mounting area.

    This is the inside of the Mini-Raptor’s front lower arms:

    Thanks K-fab. My shocks will be attaching to the upper control arms in the rear. I will make sure to add the internal bracing on the upper to help a oils “crushing the arm”.

    For the lowers though, I think I will go with the X internal brace to help with torque motion and bending on the lower arm. How does that sounds?

    Ha! Here's where I posted the pix of the inside of my arm. Was looking at all the FB posts thinking "Where'd my reply go?" - this concussion really is screwing with me - noticing things like this more and more. Argggghhhh.

    So for the bottom arm (non-shock holder), the three lines blue lines on your pic will be just about right.
    I think bdkw1 (Jack Hoff on FB) responded back with good info.

    Haha it is confusing to try and keep track of both! No doubt about that.

    Sounds good. I will work in the blue lines I drew and the ideas that Jack mentioned on Facebook. Jacks idea will hopefully help support the bungs on the end!

    Thanks a lot R1 Single Seat Mini Build!
