16 tooth CS sprocket for 400SM

Recommended Posts

There was a post quite a while ago Re. the use of 16 tooth sprockest on the 400. Some posters indicated they were using them others said they did not fit. Towards the end of the posts someone asked " where does one get these 16 tooth sprockets"? This question was never answered. I'd like to try a 16 tooth, but after a 2hour search on the internet looking for such an item, I came up blank. The closest sprocket match that I could find was for the 1980 DR400. But it was not the same catagory as the new DRs.

So my question is what 16 tooth sprockets will fit? Thumper talk lists lots of sprockets for the 400s but not 1 with 16 teeth.

Not sure if you can but if you do make sure you have enough clearance with your casesaver, it may need some grinding.

I've been wanting to change my sprockets on my sm as well. Sprocket Specialists carries any size you would ever need. I'm thinking on going to a 16-38 ratio since my bike is only on the street and I would like to cruise at 70 sometimes at a decent rpm. If anyone has any feedback on the 16 cs spocket and the fitment of it, would be appreciated. Thanks

I just mounted one up last night on my '00 S. Chaparral Motorsports has 'em, part #536-16. It was $9.95 or something like that, plus $8.00 postage.

I had to remove my case guard and trim the front of the chain slider on the very front of the swingarm with a razor blade.

It works great and allows me to change from a 16, to the stock 15, and maybe even a 14 (haven't tried it yet, but it looks like the adjusters have enough left) with no changes to the chain length.

That change along with the 4.60-18 C858 Chen Shin (only $25.99!) makes my bike great on the road!

I am still not taking any chances off road so I am leaving my MT-16 Pirelli up front for now. It is very quiet on the road.

Every case saver I have seen that was *used* had broken out of the case anyway. I will look to see if I can get it to fit back in, but I won't sweat it if I can't. Maybe I can wedge some inner tube rubber in there or something....

I might feel like a goon when I get shown, but I don't understand how the case saver gets in the way, are we talking about the front sprocket?

I have a brand new sprocket specialist 38 tooth rear if someone is interested. I decided to run a Vortex 36 tooth rear but ordered both.

I too use a 15/38 on my "S" With the 17" SM wheels. I have had it cranking at 90mph but only for a second, 65-70mph is comfortable. Changing is made easy when I opted for separate chain & sprockets so when I change from the 17" SM's to the 18/21 knobbies the chain & sprockets are all worn in to the same extent. It causes excessive rapid wear if you run with either of the sprockets or the chain worn and any of the other parts new. I also found that the OEM SM spedo gear, $45, fits on the 17" SM wheels and makes the spedo closer to correct than the OEM 21" spedo gear. I had to adjust the odometer to 85% to be close & then figure that the speed was 15% higher than it was actually indicating. I bought a Suzuki splined sprocket, not the DRZ OEM, and the teeth were slightly longer making the sprocket OD larger and I had problems getting it on with the chain slider still on and had to put both on simultaneously but I didn't have to trim the slider.

Does a 36 tooth rear fit on the sm??????? what's the absolute smallest sprocket that'll fit on the rear hub???????? :ride:

i'm running 15/39. i commute everyday at 85mph. i'm revving the crap outta my engine and getting 36mpg. soooo, i need to go taller with either a 16tooth front, or this 36 rear mentioned here. when i put on my 39 it didn't look like i could go much smaller than that. i don't like the idea of not running my case saver, but i also don't like the idea of revving the crap out of my bike daily.

Yes, the Vortex 36 tooth rear will clear the hub (chain won't hit) but barely. Not too good on the chain guide though. It is the smallest you can go and I believe they are the only company that makes it.
