Hi Julie,
The alloy it is made from is stronger than the cast/forged steel OEM part, the pivot point has brass/Bronze bushes pressed in to the alloy horseshoe which is mounted
to a EN8 steel bracket, the pivot pin is stainless or i sometimes use EN8 steel, it can also come apart if it needs to be serviced.

I designed this part many years ago, i did an update around 3 years ago. over the years i have manufactured and supplied over at least a 1000 of them, not had a failure to date.
It's also one of my favorite parts that i have done, nice to put on your desk and look at even if you don't fit it....:)

Hope this answers your question. Oh and your build thread is great. well done to you. looks like you are doing a great job.

Kevin
Thanks for the explanation Kevin. It certainly looks to be a better design than the original. I suppose parts that were manufactured 40 + years ago can undergo vast improvement from the engineering point of view, like you have proved with this horseshoe.

I have one of your horseshoes fitted to my rebuilt 400/4 Kevin, great quality part and a nice example of professional machining. I'll be putting some miles on the finished bike in the spring.

That look lovely.. thank all for your help much appreciated. Will spend some time at the weekend making final checks but I suspect engine will come out so I can solve the problem and I can give the engine a good check over.

Bit disappointed but its only January and have 3 months till the bike show..!
