Had the front 14 fitted this morning, just brilliant biggest bang for the £, easyer take off, smoother in traffic, more lively, just brilliant,

Absolutley no, I thought it might be compromised, but heaps of benefit down in 1,2,3,4, and not noticeable difference at the top, honest go get this mod done,

Commute much? gas mileage affected?

How does it affect the off idle surging? Does it make it more noticeable or reduce the surging?

I do feel that the bike could be geared slightly lower hence my interest in the 14tooth. The only thing is first gear wheelie seems already very abrupt on this bike...

I assume you don't have to change the chain?

Are you planning to use post 1000 on anything special-
wait don't answer that, being a Duc forum maybe 999 should be a good 1

I went up 2 in back ...
That's a better way to do it, by keeping the 15t countershaft sprocket.

"Gear ratios"

stock F 15T R 42T =2.8

F 14T R 42T =3.0

F 15T R 43T=2.86

F 15T R 44T=2.93

F 15T R 45T=3.0

Take your pick, Aloha Alex

14T caution!

Just a word of caution, I would NOT suggest installing a 14T with a lighter 520 pitch chain set-up, go bigger on the rear, as the tensile strength of a 520 chain is 10% less, and going from a 15T to a 14T causes 7% increase in chain tension, so in theory this set-up will be 17% weaker, :eek: with the 525 pitch its OK to go to a 14T, but on the 520 go with a larger rear. Aloha Alex

I run a Talon quick change carrier, could have gone 44t at rear, but chose to go 14t front, had a multistrada before with a 44 rear, the 44 gets very close to the swing arm, and it was a ver very mild change, 14t front is heaps better

If 14T is good is 13T even better?:p

15/44 with a 520 chain suits me fine. No swingarm clearance issues and with the light flywheel and other mods, I don't really need gearing that's any lower.

As I have not done any gearing changes yet, until all my dyno runs are complete, how does the larger rear sprocket make the chain closer to the swingarm? I would think that it would be farther from the swingarm. Aloha Alex

He's talking about the front of the sprocket where the swingarm is milled out. The front part of the sprocket were there's no chain.
