Thread: 450 exc sprockets

hi i have a 2005 450 exc. can any body tell me what the standard front and rear sprockets are when they come new. i have a 14 front and 52 rear at the moment was thinking of goin to go to 50 to stop it wheeling so much? cheers

I think the standard set up was 14/48 ( not 100% sure ).

Can you not just open the throttle more slowly or dip the clutch to prevent your wheelies ?

correct ^^^^^^^^^^^^^^

road use was 15/45
offroad 14/48

to stop it wheelying just use less throttle or move a bit further forward.

most peope run either 14/52 or 13/50 the main reason being you can use 2nd gear for slow speed work instead of 1st.

Mark.

I have always ran 14 /50 on al of my 450 s , but i mainly ride off road , my mate runs 13 /52 on his 250 4 st exc

13/50 spot on for off roading...........

have tried with the throttle but got w*****s wrist so its a bit to strong lol. no its not just the wheeling, when green laning 2nd isnt quite enough but 3rd is to much. will have to have a play. probaly leave it at 14 then go to 50 rear. cheers

"when green laning 2nd isnt quite enough but 3rd is to much."

For what ? Do green lanes not have any variation in their terrain ? where 1st and 4/5/6th get used ?

I agree with the poster above, that 13/50 is an optimum off-road set up.


Your tendency to wheely would reduce if you lengthened your wheel base by putting your rear wheel as far back as possible.

Change up and use less revs, the 450 will pull well from tickover, I 've used 14-50 and 14- 48 and they're both ok, the bike is a little calmer with the 14-48 setup.

14/50 for laning,makes a decent compromise for the road going. Dont get me wrong,i have ridden rutts in 5th with 14/50 set up but when i hit the higher end of the revs,it all went wrong!!lol. Wheelies can be had off the throttle in 5th although with ease in 4th.
Swap to a 13 in an enduro to get the use out of higher gears.

Just my experience and preferences.

i do 13-50 off road, little buzzy at 60, but great off road, 4th for most lanes
