Back in 99',a few of my trials buddy's had a machinist make several of these for them.I was able to get a couple,they originally came with track cog threads on the back.Mine eventually stripped out and I had to get a machinist to do some milling work and drill 5 holes for a chain ring.The guard was made specifically for profile cranks, hence the spindle hole.
It's going to be the final touch on my BMW park park,I'll post pics once it's completed..
