About 3" narrower - bit higher. They JUST clear the tank on full lock. JUST!. With hindsight MAYBE 1/2" more rise would have been more cruiser-ish. But then I don't really ride it like a cruiser so.........
The throttle tube area is 7/8" tubing and the actual throttle tube runs on iGus sleeve bearings. Made them myself - to fit me exactly. Very H/Duty Stainless and resin filled to kill vibration.
To get both screens on at once I had to make different brackets - but keeps all spurious light reflections at bay. The instrument chrome rear covers are PlastDip'd too. So's the key cover plate. The Blacking out rubber coated Carbon Fibre on the roadster screen could now come off - But I sort of like it. It has some interesting night visibility enhancements incorporated too.
Photo taken from behind the bike - so no I don't see myself as I ride.
