Just arrived from the U.K. 1989 VFR lower triple clamp. 41mm. Now I will use the CBR lower that I'm working on right now to replace the one currently installed on the "RC26", as I learned a couple lessons on the first one. Like how much too machine off where the steel post was welded and locating the adjustable steering stops. Current one is perfectly usable and works fine, but I'll swap it out when I'm installing some slightly different wheels and changing the preload spacers and oil level.
