Can anyone help identify this master clyinder please or help me to know the ratios? pics attached -16 8f26/ trying to work out what the 18 means on the one side, and what the other code means. It’s from a Ducati of some sort, but unsure which one and thinking of using it for an Aprilia 125 with single caliper
I don't have any personal knowledge of your master cylinder, but these people may be able to help: https://www.motorcycleraceparts.co.uk/brembo-radial-front-brake-master-cylinder-19x18 . The 18 could refer to an '18' ratio lever, as at the end of the extract below: "MASTER CYLINDER OPTIONS Listed below are size options and recommended applications: 19x20 - 19mm Dia Bore with 20 Ratio Lever - Twin front Caliper Set-up, remote reservoir - Most popular for bikes without Brembo race calipers. Harder to pull with least travel giving a more responsive "sharper" Feel 19x18 - 19mm Dia Bore with 18 Ratio Lever - Brembo twin Race Calipers, remote reservoir - Used by almost every works rider using Brembo brake calipers. Best combination of feel and travel. 16x18 - 16mm Dia Bore with 18 Ratio Lever - Single disc and Supermoto Set-up, remote reservoir - The least popular although can be good for supermoto and 125 to increase feel. Easiest to pull with most feel. Please note: Brembo master cylinders require a M10 fine - 10 x 1.00mm thread banjo bolts (single or double)." Hope it helps, but apologies in advance if is not relevant. Tom.
