450r sprocket on a 400ex

[justen08]

I just wanted to know if the 450r sprocket is compatible with the 400. I was told that the sprocket would fit on my 400ex.

I forgot to say in my first post it is the front sprocket i was inquiring about.

front no, rear yes.

Thx for the reply honda4life05.

what size does the 450 go to like 36-40 or 35-42 what are the sizes?

i have run a 13T 450r front sprocket before. It slid right on, but mine is a 1st gen 400

[justen08]

Well i had the sprocket and before i got my answer i tried it. It will slide on but it will not stay on b/c the 450 sprocket doesnt have the holes to screw the keeper on.

yeah the 400ex sprocket is held on by two bolts threading into the actual sprocket. 450r sprockets get held on with one bolt going through the middle.

[440ex. ehhh!!]

i thought plastics, reverse and lights were the only differences on 1st and 2nd gen. :confused:

the 05's and newer have a different counter-shaft spline. and the way it was held on mine was a really thick circlip that went in the groove on the counter-shaft, but when i got a new sprocket i bought the two bolts and the keeper
