My Raptor is supposed to be here the first of next week and I want my dealer to put a 12 tooth sprocket on during set-up. The problem is they will only use a Yamaha part on it for warranty reasons and they don't know the part number. I called one of the biggest dealers in the area and they didn't have a clue to what would fit it either. If someone has had a dealer install a 12 tooth front sprocket on their raptor could you give me the phone number of the dealer and a knowledgable contact persons name? And yes I've read all the posts about the YZ250 thats supposed to fit it but the dealer won't order it unless he's positive it will fit.

 

I am not sure what the part# is but one off of a 98-00 YZ250 fits it(fine splines) It is very easy to do, just make sure you have a 32mm socket. If you pull the peg when doing it, it makes it alot easier..

Hope that helped

 

Ahh, may sound dumb but why would you want to put a 12 tooth front sprocket on? Wouldn't you loss top end.

 

Yes you do lose a bit of top end but it is well worth it as you gain the needed low end. For riding trails (my main riding ventures) it was a must. I changed mine last week and rode all weekend for hours.......I loved it, perfect for the tight trails of the Rockies. Besides this beast still has tons of top end even after the switch I was unable to get out of 4th anywhere where I ride.

A sprocket for a 99 or 2000 YZ250 fits it just fine. I ordered mine from Renthal and put it on myself. It is cake to do. However as previously mentioned you need a 32 mm socket to remove the bolt over the sprocket and removing the peg gives you the room you need too. It can be done without the socket (I did it using a very large crescent wrench over the top of the bolt and turned the wrench with a large handled screwdriver through the end) but it requires a couple guys and is certainly much easier with the socket.
