I ran a 13T C/S for years on my 400 and never had an issue, I always stuck with the 50T rear so I cannot speak to how big you could go. The 13T was always low enuf for me:thumbsup:

99-00 WR 400 Rear 42-74 (stock = 50) front: 11-17 (stock = 14)

This info is lifted straight from Sprocket Specialists

I've ran a 11 tooth from them on my old Kawi. Never had a problem with exessive chain where. Changing the front is probably the easiest and quickest way to lower gear ratio.

So I see they make as small as an 11 counter, has anyone ran a 12 counter? Any issues??

How much low gearing do you want and for what kind of riding? Two teeth down on the front sprocket will turn your 400 into a tractor:crazy: I did it on two bikes. I liked it on the kawi, but not so much on my XR. It made the gears so short I felt like I had to shift all the time. It felt pretty good in tight technical stuff, though.

Well I want to buy a few different size counter sprockets so I can change them over easily as necessary without having to worry about chain length. I'm trying to decide what rear sprocket to use and just leave the rear alone then change counters as necessary. So mostly I wanted to make sure a 12 or even an 11 was not so small that it created chain life issues.

I've been riding WR's since 99' and I have never ran anything but a 50T rear, I have gone as low as a 12T CS and as high as 15T CS..... if you go to a 12 or 11 you will likely have to remove a link....

I have 12T right now on my 07' but they come stock with a 13T....

I have ridden everything from Desert to nasty pack and carry technical single track and on my 400 I was always fine with 50T and just changing between the 13, 14 & 15 with out chain mods...:ride:

Can you just slap the 12T CS on the 07 WR450 and go? No need to remove a link just adjust accordingly?

Thanks!

Yes - with the stock chain length I am on the 6th mark from the rear on my axle block. And you can install it without removing the chain or case saver:thumbsup:

I have raced once and did some long rides with it and I am going back to the 13T.... I find it one dimensional with the 12T, too low and slow and 2nd gear starts at the races are hard to keep the front wheel on the ground. If you ride a lot of tight and technical you will like it:ride:

Drop one tooth in the front from stock should not give you chain problems or require shortening it. My 2 cents is drop a tooth in the front (alot cheaper than messing with the rear) and ride for awhile before dropping another tooth.

Dropping from 14T to 12T is pushing the chain system and will have a BIG effect on gearing.

I dropped from a 14t to a 13t and it made all the difference in my riding... I trail ride and love the lower gear for crawling through the technical stuff. If you race open trails and open range, don't gear it down, if you like tight tech. stuff, I highly recommend dropping a tooth
