1200 DVT Rear Sprocket 42 Teeth Conversion

Think @MaDProFF has just done his my 15 DVT which will be the same

 

Changing from the standard 40 teeth to 42 would lower the gearing by 5%, I think. So sixth gear would presumably become a real top gear instead of in effect an overdrive. Is that the idea? How is that an improvement then?

 

I’ve done this on previous bikes and they rev out much faster. So they feel more responsive.
To be honest the DVT has more than enough grunt for me so I haven’t bothered.

 

Just need a 110 link chain too, which I'm sure you know if you've done it before. If not, it will raise the ride height a bit

 

I did, about an inch in the seat when the chain was correctly adjusted. I run a skyhook tho, so chain needs to be real loose.

 

Cheaper to do one tooth less front sprocket and use same chain. Very nice mod.

 

You'll still need to adjust the chain and affect ride height, just other way around. But may lower rather than increase rear as wheel heads backwards

 

Less stress on the internal parts by changing the front sprocket.

 

Think you will find its the opposite. A tighter front turn puts more press on the drive shaft. So the internet (and some ducati specialists) have said for years.

 

Riding the torque or chasing the horsepower, that is the question.

More frantic does not necessarily mean more fast and gear changes without a QS cost time/speed. It's a deceiving effect when the bike is getting through its rev range quicker but often the bike isn't going quicker but feels like it is, especially if you use traction control.

I've got a pre-DVT 1200 engine and have tried gearing from 15-39 to the equivalent of 15-44 approx and have been surprised that speeds have often been around the same on the same bit of tarmac.

Speed-wise to really make use of big rear sprockets (or small front ones) you need to be hanging around at the top of the rev range a lot of the time, if you ride your Mutly like that then it may be the way to go and it's easy enough to try it and revert if you don't like it so there's nothing to lose, especially if you buy a decent chain tool.

It'll make it feel more lively though no doubt, and will extend the front suspension quicker on bigger throttle inputs, depends how and where you ride the bike and what top speed you want the gearing to achieve.

 

Yeah I've never heard anyway say LESS stresses by changing to a smaller front either - same link/tooth hits are increased plus possible problems with swingarm clearance and a tighter chain run with smaller front sprockets.

 

Reason I like the 42t is because it does just that: raises the revs a tad so it’s easier around town in 2nd and 3rd even.

 

I hesitated doing this mod but after doing it I'm really happy. Makes the bike much easier around town and at slower speeds. I mean how often do you need the extra few MPH at top in 6th ?

 

The purpose of the high "overdrive" 6th gear is more relaxed cruising on autobahns/autostradas, not a higher top speed. If you don't plan to do long distance touring, that would not be an issue for you. Some of us do, however, and the considerations are different.

When the factory are deciding what gearing to specify on the models the sell, I suppose they can't really please everybody and one of the advantages of chain drive (as opposed to shafts) is the ease of varying the overall gearing.

 

FWIW both 5th and 6th gear are 'overdrive' gears on these gearboxes.
