Both my MK1s and the MK0 have the same bars with English Doherty grips and twist throttle. I put a wider Aluminum bar on the Rust Bucket MK1 because I was riding it daily for awhile and the narrow BSA bars beat me up too much. I am trying to find a chrome plating shop. Eventually I want to get the Rust Bucket MK1 back to original.
More MK0/MK1 handlebar pics.
The kill switch is drilled and tapped on the left side of the MK0 bar and the same kill switch is clamped the right side of the MK1 bar.
