Just a comment, I have one of those plates from Australia. It is top notch, well designed, well made and beautifully finished.
WASP who is a great addition to this forum and to ADV rider designed this plate. It seems tha that is how he operates his home based business in addition to his regular job.
I make my living selling my intellectual property and I view someone sharing the measurements and design of someone else's work as stealing. There is no difference between a $29.00 part and making a knock off of the ALT Rider accessories, just the retail price.
I have been working with a designer on custom foot pegs and so far my cost is just about $1,000. I have been riding the prototypes for 6 weeks. When I read posts like this it confirms my view to only offer them to people I know. Will I make a buck? It wasn't a project to make money just to get a great set of foot pegs that worked with my large wide injured feet. I expect I will never break even, but that is fine, they will work for me.
Please don't steal someone else's work, at least ask WASP for permission to use his design.
