What are the tooth counts on the sprockets on a 98 f3? and also where is the best place to but a new chain and sprocket front and rear? What do I need to look for when buying and what should I buy. Any suggestions appreciated. Aftermarket or stock?

 

Stock you're running 15T front and 43T rear with a 525 pitch. I'm still trying to find the best place for stock sized sprockets for my bike as the previous owner geared it down. Maybe someone else can chime in...?

 

"VORTECH" ??? they have a link here on the forum, I looked at them for a new 520 conversion it was like 180.00 for front and back sprocket and a new chain.

 

Try Ebay. I just got a 520 conversion set for 149.99 shipped. Also I was recommended to go one down on front, and 2 up on rear. That's what I got, and I just love the acceleration now.
Company was called "Sum of all parts"

 

I got mine from Sum of All Parts also. Works great, Although mine took over a month to get to me because They had a delay on the Front Sprocket for my bike. I called them back after like 3 weeks and they said that they thought my order was already sent. I was like ummm no. I have no sprockets here. So they sent me my set. Would have been nice if I would have ended up with 2 sets. Might have sold a set or kept it for future when the first set wheres out.
