300ex mx gearing?

[Out_Sider]

what you all with 250x/300ex's with 18in tires run for gearing. right now i have 12/38 gearing..and its not gonna work out when i get the 18's. so what do yall run? i've heard 14/36 is the best, but what are yalls opinions?

I run a 12-38 on tight tracks then i will change over to a 13-38 on more open tracks...the smaller front sprocket gives alot better bottom end out of corners..

and i have 18in. rear tires

[Out_Sider]

so stock gearing is good?

[roostin_dale]

for my prefrence it is:)

some people like it different though..

i've heard of alot of people running the 14/36 gearing with 18's, and it even says in on douggust's website, so idk, im really confused :confused:

I have 18" rear holeshot mxr's and i run 13/33 gearing, works great, i used to run 14/38, but i felt it had too much bottom end and i even race SX. I usually run a 12 tooth front sproket when i race SX and use my 13 tooth front when i ride mx.

where did you find a 33? i've never seen them, and do you like the taller gearing because it lets you stay in each gear longer, or what? :confused:

Aight thanks man, i'm gonna be running this gearing probably, 13/34, because i dont really want to use a 14 t because i cant get my case saver to fit.

I changed to a 14-36 after i posted here. I forgot to reply and tell ya that i've ran prolly 5 different set-ups and the 14-36 is the best for mx IMO!

"14/36" This is the gearing I used to run until I broke my 36 and had to use my spare 38 rear. I have run the 14/38 ever since, just seems like I am much faster in and coming out of the corners with the 38.
