Title: A50 Royal Star swing arm length
Post by: chaz on 02 Mar, 2019, 18:15
just checking around the Bee today. the rear frame rails have been cut off and replaced from curved to Hexagon straight tubes.
measuring the swing arm Im wondering if it has been extended , mine is approx 24inches from swing arm pivot to centre of the adjusting slot, is this normal or extended?  .
