Lightbulb Monster 1200s Sprocket/Chain size - Reviews

Hi All,


Based on many threads I have read in here and other forum there is "debate/feelings" in regard to the sprockets and for those new to Ducati getting use to how they are vs the mob that state enjoy what you have its a "Ducati".


I feel there is right to both sides of the argument and was hoping to have this little thread to help people on both sides come together and share their experiences and to also offer advice and have a one stop thread to know the ins and outs of it.


What top end speed are you loosing by doing the mod?


What kits are for sale for the mod? recommend any sellers and kits?


OEM Front sprocket 15; Rear sprocket 41; 525 for the chain.


1)Explain why is 14 front sprocket good/bad, yes it is the easiest mod but what will it cost in the long run?


2)+2 Rear Sprocket mod, why is it good/bad, what is required for this mod/


3) Anyone done -1 / +2 Mod, reviews of this?


4) Full front and rear and convert to 520, whats the point and worth it?


Any speedo differences from these mods? the feel of it?


Finally any guides for people to do the mod themselves.
Any write up step by step so we can empower those to try DIY? as I feel this is missing in here as too many just take it to the dealer then trying it themselves.
But to cover this side how much did you pay for the dealer to do the mod?

I did 14 on the front and 43 on the back just to have lower idle speeds in the parking lots and city.
I know that the top speed was affected by this from ~255km/h to a maximum of 200km/s but with a naked beyond those speeds is pure madness.
Also the new rear sprocket even thaught is has 43 teeths is lighter by 410 grams than the oem one.

Let me begin by writing that there is no such thing as a "one stop thread".
Invariably, threads do spin-off and people tend to want to create new threads because theirs is the next best thing to sliced bread.
Now that's out of the way:

What top end speed are you loosing by doing the mod?

Sometimes (on some bikes) you don't lose any (or very little) top speed by lowering the gearing since the engine can't reach redline in top gear with the stock sprockets.
You may wind-up with the same top speed albeit at a higher RPM. In fact, some bikes could actually gain top speed as it moves the RPM's into the powerband.

1) Explain why is 14 front sprocket good/bad, yes it is the easiest mod but what will it cost in the long run?

A 14T (-1F) is a cheap mod for a new bike as you don't have to buy a new chain. Howerver, it's a lot of gearing change for a Monster and equates to +3R but that's just my opinion. If this was about a Panigale, my answer would be different.
Once the chain and sprockets are 3/4 into their lifespan, I would prefer increasing the size of the rear sprocket (from 41T to 43T) and leaving the front as a 15T.

2) +2 Rear Sprocket mod, why is it good/bad, what is required for this mod
As above.

3) Anyone done -1 / +2 Mod, reviews of this?

Yes. -1F on the Panigale (perfect) and +2R on a Multistrada (perfect also) and just purchased new chain and sprockets for the Monster.

4) Full front and rear and convert to 520, whats the point and worth it?

Why would you want a weaker chain on a streetbike that wheelies a lot?

5) Any speedo differences from these mods? the feel of it?

Nope. Speedo not affected by the gearing mod.
