16 Tooth sprocket

Post by bagpuss » Sun Feb 28, 2010 10:53 am

I recently switched out (well asked my dealer) the 18T to 16T sprocket. Wow, what a difference..

1. Cornering is much, much easier. Because the power delivery is much smoother you can ignore the clutch while cornering. This leads to you being more relaxed and concentrating on the lean/speed/approach more.

2. Feel. Subjective, but the bike feels much better for my liking. Less snatchy but with all the power when you need it.

3. Sound. Subjective again, probably even placebo effect, but just my opinion.

Hey Bagpuss, I know sprockets have teeth but does this really fit under the heading of "Teething Problems". :lol:

I put a 16 T on my 950SM and it was much better. The original was a 17 T I think, so now you've got me wondering. If the SMT has an 18T as standard it might explain the lack of wheelie action ( and I thought I was just riding more sensibly ).

Cheers

Bagpuss,

Thanks.

I also have 16T sprocet and at 4000 rpm in 6 gear
it goes about 100 kmh.
At 5500 rpm it goes about 140 kmh.

spoke to my dealer about the high gearing on my bike-he suggested changing from 18t to 17t.i notice everbody else seems to go for a 16t sprocket. Any suggestions/advice. I mainly ride bendy country roads and only ride the highway once in blue moon.

Add one more happy camper the 16 tooth club. The bike is much smoother and tends to be easier to keep in the 4000 to 5000 rpm sweet spot.
Now if they could just fix the squeaky rear brake. I tried the "run-in" treatment as described here and that solved it for about 100 k, then the squeak came back. The tech noticed strange wear patterns behind the brake pads, so proceeded to chamfer the brake pads and applied anti-squeak but to no avail. I think it is just part of the package, and you just have to accept! Congrats to the members who have eliminated the problem.

Just put the 16t on mine.

The reason I put it on there was to reduce the harmonic vibes I was getting when cruising down the highway. I have a strange buzz right at 5grand which is about where I am while in 6thgear on the highway.



Makes the first few gears a little short but 3rd, 4th and 5th were great. I didnt get a chance to try highway cruising in 6th.

I need a long ride to confirm but so far it seems to be better.

Once my first service is sorted i'm dropping a tooth on the front and adding 1 or 2 at the rear...did this on my old Tuono and it was a riot on the backroads and only added about 4-500 revs at 70mph so unless it was a really long run at steady speed it was never an issue.

Im another happy customer of the 16 tooth sprocket...

Helps with the snatchy town speeds riding and gives it that nice bit of extra zip !

Also makes 6th gear more useable for cruising speeds on fast A roads and Motorways.

I would like to hear if anyone has done the 17 tooth. I am thinking the 16 will make 1st gear too short for my liking, but a 17 might be spot on!

**Edit: Sorry, newbie mistake. The stocker is a 17. I thought it was 18. So, looks like 16 is the magic number! And here I was thinking all you crazies were dropping 2 in the front! :D

Changed to the 16 T sprocket after 1st service. Thought fuel consumtion might suffer, but the SMT turns out 16.7 km/l with liberal use of throttle, which should be good for 300kms.

I have just received my 16 T sprocket and I have some doubts before install;

first, what tools is necessary to install it in my home?
second, I have now installed the O2 sensor eliminators, and togheter the 16T sprocket both will increase a lot the fuel consuption?

thanks

Marcelo:

I've done both mods and haven't noticed any significant change in fuel usage, maybe a few less miles before the light comes on but I do mean a few less, 5 tops. I've also disconnected the 2nd/3rd gear limiter cables.

I got the dealer to change the sprocket during the second service so can't help you with removal.
You always have a choice

Thanks Beyond

I have read too about the 2nd/3rd gear limiter cables disconet in specific topics......Well sounds like these three changes;
(O2 eliminators+16T sprocke+2nd/3rd gear limiter cables disconet ) is a unanimity for SMT 2010.

I have also done all three, my fuel consumption has gone from 15.8kms per 1 liter of fuel to 13.8kms per 21 liter of fuel. We worth doing.

In my case I have bought the Renthal 16T sproket, but I can see acording SMT microfiches that there is the OEM 16T Damped sprocket.

Is there signicante drive efects using conventional sprocket (Renthal) instead of the KTM Damped sprocket? someone here install the 16T Renthal sprocket?

Changed to the 16 T sprocket this weekend and really good. In the road sounds like the motor goes free using more ~700rpm in each gear.

Don't these goons at the regulatory commissions (EPA etc) realize that enthusiasts buy these bikes? They crack the whip on the manufacturers forcing them to put on parts that will allow the bikes to pas db tests and such only to be tossed in the trash by the people buying the bikes because the bikes run like hell. How does it help the planet to throw 20 lbs of exhaust material, and a pound of sprocket into the dump. Not to mention the resources burned up making and distributing the new replacement parts. If they would allow the relatively small number (compared to cars) of motorcycles to be made the right way in the first place, it would be better for everybody. Of course, we'd miss bitching about the bikes on the forums. :roll:
