All knowledgable TT followers, I look to you for some advice! I am getting ready for the upcoming season and I need a chain and sprockets for my 09 YZ450. Since I am not as much of a race junky these days (just getting back into the MX scene) I went with an O-ring chain. Now for the sprockets. I was looking towards stock sizes since I liked the bike last season and I am pretty sure it's still stock gearing. Anyways, I used a new dealer since I live too far from any of the places I used to deal with. For some reason the guy kept pushing a 14t front sprocket. He said the 14t is less abuse on the equipment and a better choice up front. He didn't have a larger rear in black to make up for the larger front so they sold me a 49t rear. This just seems like something is off and before I do anything with those parts I am looking for advice on gearing. Should I order a larger rear? Smaller front? I don't know why this is so difficult but I am completely confused.
