Thread: Estimate for Motorcycle Part
After a quote for a rear motorcycle calliper hanger.
I can supply technical 2D and / or 3D drawings if needed,
or machinist can figure it out from parts supplied.
But I'm very specific about how it should look and it is
a high load bearing part so will need to be cut from decent alloy.
I'm in London.
There are a few people on here that will make this for you. I suggest you post a drawing so they can see whether or not their machine is capable.
Will do mate - thanks for reply.
Here's the part I'm after.
Its pretty basic, about 150mm x 130 x 70mm
It needs to be strong. Any Motorcycle guys will know immediately what it is / does.
I can supply the rear wheel and swingarm for you to take your measurements / tolerances etc and then machine as you wish.
Its not for production, its for a one-off special build.
Turnaround can be unto 6 weeks.
I'm based in London.
You can see it in place here, outlined in green.

Hi Ratch, hope you dont mind me making a suggestion but this caliper mount wouldnt work. The caliper mount would eventually rotate and tear away. You need to increase the mass between the caliper mount and swingarm mount.
But this gives an idea of what's needed and should be enough to get an estimate.
The details can be sorted afterward.

Have amended the design slightly - but its essentially the same for an estimate.
Looking at this it looks like you have 2 piece design in mind and that just won't work and look the same.? It would need to be much more robust at the spindle portion to allow inter locking joint to stop rotation.
This part needs much more work on design and strength because has robsk1 says it wouldn't last 5 mins under heavy breaking with these proportions.
I Also doubt anyone will give you a quote for an incomplete design thats flawed in such a major area given the nature of it's importance.? I certainly wouldn't.!
This is a 1 piece design. I don't know where you got the 2 piece from.
There is plenty of meat there for this to perform as intended and current
rear calipers on more powerful bikes are nowhere near as bulky as this
so I feel you're either out of touch or just plain wrong.
In any case, I'm looking for an engineer to work with me on this, not just an operator.
I'm only precious about the aesthetic, the engineering can be tweaked once the job is agreed.
Having said that, it could still be a 2 -piece item and work well.
Simpler to make if the hanger and brace are separated and slide into each other
as it could be cut from 2 thinner pieces in just 1 axis...
