The duke390 is a surprisingly good cruiser. I too went up to a 16t front sprocket but lately I’m thinking of going down to a 42t in the rear as well. Great video!
@@sawbach8971 sorry for the delayed response. Going down to 42t in the rear was a little too much. The top speed dropped as well as the acceleration. I’m 205lb btw. It may be a better fit for someone lighter.
Well done video. I’m changing the engine sprocket on my 390ADV and couldn’t find the torque value for the 2 screws anywhere. Blue loctite is a great recommendation. Two questions: From the color there seems to be some anti seize on the splines. What do you think? Second, you are using a stand at the rear wheel. Where can I find one? Thanks
How do you know if a sprocket will fit the bike? Trying to buy a new set here and having trouble finding a kit that specifically lists the duke that’s actually in stock. Just trying to find em piece by piece now.
Well I can tell you a 15T front is about as large as the front can go without removing the guard. The rear has more possibilities. I personally just ran 15/45 which is 1+ front and stock rear. The oem chain length will fit this.
did the 16/45 sprocket set up go will on test run . is bike sluggish on acceleration or is the 390 engine powerful enough to cope with the longer gearing
You'll notice little to no change on the acceleration. What it did was calm the revs down on the interstate. In 6th gear at 80mph it use to run 8000rpm now it runs 7500rpm at 80.
I didnt notice any significant change in acceleration or top speed, but it did bring the revs down at cruising speed on the highway which is what I wanted.
Pretty much every video following this installation has the 16t sprocket on it. Its still on it to this day. You can't "fuck up" this bike with a simple sprocket swap.
That’s a driven sprocket, You can buy it from Oem cycle.com it’s also free shipping to India. But it’s more logical to replace rear sprocket and replace chain which has lesser links. Overall you could reduce rotational mass aiding in better handling for duke 390.
love all of your videos, been using them to do a lot of the non-engine related service myself on my new RC390 for the first time.
I’m in the same boat, I do a lot of highway riding on my duke 390 and I’d like the rpm’s to be a little lower, thanks for the video. Great job
I want 16 teeth spocket. Where i get this.

Did you put the 42 on? I bought 16-43 combo but haven't tried it yet
@@sawbach8971 not yet but I got it. It will be next week. I’ll let you know
@@thebulgarianguy8461 okey. :)

Thank you! My sprockets and chain arrived today finally, so I’ll be blindly delving into this soon! 🤣

You can find the stand at harbor freight and some spools on amazon to go with it. Some anti seize isn't bad but not really necessary either.
How is ur experience overall after 16t sprocket
can i install 14t from duke 250 & 42t from duke 200 in ist gen duke 390 to get low end torque
where can i buy 1?
Pienso que pusiste la arandela de seguridad del reves!!!
Looking for torque spec on front and back
Can I use 14T sprocket for Duke 390, my duke is Jerk on low RPM

Do remember the part number for this sprocket? I used the link below to order one for my duke, and they sent the wrong one.
Thanks
Driven Racing 2290-520. SKU: 1212-1179
Curious if you think 1st gear feels more usable w the 16t. Is it just a split second longer between gear changes now? Thx for the vid.
It's not going to make a major difference but it's enough to make the bike feel better all around
Thank you

Think I’ll do this to mine, nice video thanks
Thank you
Did you have any issues with the speedometer after the install?
No, the speedometer gets its reading from yhe ABS sensor so gearing changes to not make any difference.
Pls help I wanted to buy it somewhere
How was the performance?
I didnt notice any significant change in acceleration or top speed, but it did bring the revs down at cruising speed on the highway which is what I wanted.
@@MotoMedicine904 thank man 👌👌
Where is the test ride of this version of bike? Just in case to confirm that you didn't fuck up that bike.

Hi . I am from India I want to oder 15 t front spocket only . Where and how can I buy it from.. my model in duke 200 . Please help me

Bhai KTM showroom se duke 390 ka front sprocket bolke lele mil jayega easily
You could have taken a link out of your chain when installing the 16 tooth sprocket. It would have allowed you to keep the proper wheelbase.
Taking a link out would have made it shorter and it would have no longer fit.
