you probably want a 19 x 18 if you are racing short circuits and do any trail braking. 19 x 20 is more for roads riding/racing where trail braking isn't so much of an issue.
19 x 18 gives less "bite" and therefore more feel. 19 x 20 gives a harder lever, more instant braking, so less feel
Got to admit I didn't know that either. 19 x 18 is what I'm after then! Changed the advert, thank you.
as the std levers are brembo anyway then a black copy of the std lever will probably be best match if it's for the 999 try these... DUCATI 749 999 BRAKE & CLUTCH LEVER SET 03-07 | eBay NEW Brake & Clutch lever PAIR for Ducati 749 999 848 1098 1198 Streetfighter | eBay
I run a 19x20 and find it gives enough feel. Closer to the bar, more feel, further out, more bite IME
I had a 19x18 on my old bike. TBH it was ok , but not a vast improvement on the stock 848/1098 item. Not sure what the ratio is on the oem item? My road bike has 1098 stock master and P4 34 calipers from a crashed S100RR and it fecking stops! :Jawdrop:
