If you can pick the difference, you're good. The cushioned sprocket is a bit quieter.

 

Thanks Boldor. Undamped it is then. A new noise to listen out for might help distract from the ticking time bomb sound!

 

I bought an undamped Renthal for mine,can't say I hear any difference but it transforms the riding of the bike.:yes:

 

I also went for an undampened 15T counter-sprocket and i can only hear or feel the difference when pushing the bike around with the engine off.

 

When you are tootling, not accelerating or engine braking, when the exhaust note is the quietest. Put on your open face helmet and look down at the sprocket cover and you can hear the chain spinning over the cog. You can't hear it just riding normally, with your head up - I can't anyway.

 

How do you guys like the 15:40 gearing?

i'v only ridden my 690 duke for 40km in standard mapping mode.
And i must say it was hard to do "roll-of-on-gas" wheelis on it.

i'v owned a 690 sm and smc before and on them no problem to wheelie without the clutch and with stock gearing.

 

I find 15t front sprocket livens it up but I will go 42t rear soon too as the standard gearing is a bit tall.

 

I think the whole ide from ktm with the standard gearing is to not make it so wheelie happy.
The point of this is that the abs will stop working and you have to switch of/on the ignition to make it in sync again.

 

"the ABS will stop working"?
Eh?
You mean the wheels will turn at different speeds when you are riding along...er...no. The engine will turn at adifferent speed to what it was but the wheels are in contact with the ground and will turn at the same speed as before. Change a tyre outer diameter and you are gonna effect the ABS ...somehow or other.

 

Hold on, i will explane.
There is and wheel speed sensor at the front and back wheele.
If you do a wheelie or a rolling-burnout the speed sensors won't understand whats going on and the abs will "go out of sync"

My point about the stock gearing is: the bike is not very wheely happy if i compare it to my old 690 sm & 690 smc with stock gearing.
And i think it's the way ktm want to keep it with this duke
