Yes they are very popular however, the problem is the sizing. Each bike requires a different length and diameter, depending on the shock and mounting design. For me to get things made in a cost effective manor i'd have to be producing at least 300-500 of each size. We're tooled up for large batch/mass production on our CNC machines. A job like this would probably be best suited to a small tool room lathe, which both the chap in Ireland and Burgtec have.
