There isn't an OEM triumph sprocket in 18 or 19 teeth, only 16 & 17. They're made and sold only by after market companies.



There must be an 18 available because it is standard on '06 Speedy, at least after some production date. Not a 19 though. There's a lot of discussion here on the merits, pros and cons of going with a 19 on the front. I tried it and went back to 18.
