I haven't been able to cross reference your belt, part number 5S7-46241-10-00, to any other number and I do not know how they count the teeth on the belt. It may be metric eg. with so many teeth per meter or, it could be counted in teeth per foot, I dunno. I do know that the tooth size (height & width), shape and spacing, have to fit the sprocket.
I have a belt with about 12,000 miles on it, that I took off of my 950. I changed it because I had a vibration problem. I later found the problem to be a loose nut on the main drive pulley. I have been keeping the belt as a backup. The Yamaha belts are supposed to be good for about 35,000 miles. If you are interested, PM me.
I'm always working very diligently to discover the obvious.
