Anyone know of a company manufacturing a disc brake conversion kit that will fit the motortrike kit on a 2008 Harley... Apparently I have a Trog conversion. I got an email from motortrike, they do not make disc brake kits for the older rigid axle HD conversions. Anyone have any info on the axle and what maintenance should be done on it. I bought the trike already built and there was no manuals, etc with it.
