1299 S with 41 tooth rear sprocket

Freddy46 · Feb 1, 2016

I had a 1199 S with a 41 tooth rear sprocket. I didn't try with the original setup (39 tooth) since it has been modified before I brought the bike but I really loved my 1199 S with 41 tooth!

Obviously, I crashed my 1199 S. Now, I ride a brand new 1299 S with the original setup (39 tooth). At low speed, it can be pain in the ...! I do only street ride (no track).

Considering that the 1299 has a different engine compare to 1199, I'm hesitating to go with 41 tooth.

Has someone already installed a 41 tooth rear sprocket on a 1299 S? Any feedback and/or recommendations?

I went with a 14 tooth FRONT sprocket.. Don't need to change the chain and it's PHENOMENAL.. It makes 6th gear on the 1299 actually useable and it makes 3rd through 5th utterly berserk. A definite must, as far as I'm concerned.

I ride my 1299S with 15/41 final gearing and it's perfect for country roads. Never would go back to 15/39, it's OK with 1299, but 41 at the rear is definetely better. 14 at the front is not recommended by Ducati, by the way.

Mine is 41t on the rear but I haven't raced it yet. But I also have a 39,40 and 42. Gearing is a "living thing" like suspension setup and changes from track to track.

It is curious ducati went back to the 15/39 after the hit the 41 tooth sprocket was on the 1199. I get the extra torque of the engine playing into the 39 but still. Especially since the R has the 15/41 setup

I figure it was because the majority of changes/upgrades they made to the 1299 were to make the bike more "rideable" to the general public. They made it handle better, made it more stable, made it smoother and gave it more torque with a broader mid-range.

Going higher on the rear sprocket makes the throttle response a little more "twitchy" and sudden...which doesn't make the bike easier to ride for the general public.

The R still gets the 41t because it is a homologation special that is designed for the race track...and I am sure they assume it isn't the bike the general public will buy for tooling around on the streets.

When was the 1199 ever not 15/39? I know Ducati offered a 41 tooth swap at a discount for a while but I'm not aware of 41 ever becoming the stock (non R) setup. Do recall that the R also has a few hundred extra revs to make up for the lost speed as well.

I thought around '13-14 the 1199 came with a 41 tooth rear, like how they made the regular seat like the one on the R. I could be wrong.

I went to 15/41 on all my Pani's. But it needs a longer chain, as mentioned in multiple posts on this forum.

Kevin: all I know is that SL came with 41.

On my 14 it came with 39t and a horrible seat. I wish they would have though.

Shorter gearing means it will be peppier off the line (since first gear is rather high)
*You will also have to shift more often out of the lower gears to avoid hitting the red line. On the street is is actually better but on the track you run out of gear on a long straight.

I tried going down one tooth on the front and it helped a lot taking off in fist from a light. However at the track I found I had to shift a lot more to keep out of the rev limiter.

**I had no problem with going one tooth smaller front sprocket. ( It is approximately the same as 2 and 1/2 teeth up on the rear..) You also don't have to change the chain but it makes the wheel base longer and will throw the steering geometry off a little. Not a biggie on the street anyway

Be sure to reset the calibration for the Speedo for any gear change or any tire changes. it can be done from the settings menu in the guages.

I'm curious how a dif. front sprocket would change the wheelbase? Shouldn't the only dif. be the number of teeth as opposed to total diameter? I assume that if the wheelbase is affected then you would have to compensate by extending/adjusting the chain accordingly.

Smaller diameter front sprocket (- one tooth) means the rear wheel moves further back. Not a huge difference (probably less than 5 mm.) but every millimeter counts if you are setting it up to race. On the street you will never notice it..

However expect less miles per gallon because it is revving about 500 rpm more than it did before at the same speed.

These bikes are not known for their fuel economy anyway what is another 5 miles less per tank LOL.

Thanks for the info. I come from wrenching on beater/exotic/track/drag cars so I'm starting to get my feet when on bikes.

Exactly what Speedy said...

Speedy or Shilling - to clarify when you do the 41t it raises the revs 500 from what the dash shows(7500 is really 8000) or it revs faster so where I would normally be lets say 4500rpm in 3rd gear it now gonna be 5000rpm in 3rd gear at same throttle amount?

The dash shows the correct rpm; what it does is raise the rpm for any given speed, i.e. If you normally were doing say 4,200 rpm in 6th gear at 75 mph, you would now be doing 4,700 rpm to go the same speed in that gear. (these figures are just made up to give an example and are not correct).

Here is what Gearing Commander shows for the 41 tooth setup vs. stock

Less mpg but more thrust!

You know, strangely, my mpg is exactly the same on my commute.. I think it's because I have to be on the throttle LESS to get the result I desire and I can actually be in 6th gear, without having to go 85 mph.. I always get around 130 miles from a tank on my weekly commute to work. I take the identical route every day.

Like I said, I went 14 tooth front and am loving it.

Thank you Shilling.
