2+ or even a 3+ larger front sprocket

Can anyone tell me if it would be beneficial for me to go to an 18t front sprocket if I wanted to take a road trip on my bike ? I realize I would lose some low end acceleration but I drive kinda slow anyway.

What about up one in the front and down one at the rear ??

Go with 17/44. Best gearing all around!

Generally, any change by more than 5 % in overall gearing ought to be done on the basis of tailoring for a fairly specific reason.
For example, to avoid a particularly bothersome rev range while cruising in 6th, that only becomes apparent after many hours of such use.
IF an 18 will fit, it would be a 12.5 % change in overall gearing.
A 17 X 42 will net a 8.8 % change in overall gearing.
A 17 X 44 will net a 3.8 % change in overall gearing. (this one is a popular and well proven change for the group that wants less buzz while doing highway speeds steady state in 6th)
What are you after ?
A certain RPM band in 6th gear for a certain road speed band?
Do you have the gearing calculator so you can easily figure out what front/rear combination will net you what you want, or want to avoid?

18T will not fit. It will rub the casing surrounding the sprocketwell.

Even if it did it would require so much clutch slippage just pulling away from a stop sign that you would be burning through clutches quicker than chain kits

Thank you for confirming. That is one tidbit I wanted to know. After doing a little more research I've decided that a 17T will be the way to go. I still haven't looked at any calculators cuz I wanted to know what set ups did what in real world conditions.

I just want less revs on my road trip. And afterwards I'll swap out the rear sprocket for the regular one. I drive pretty much like what the racers and crotch rocket guys would call like a pussy. I'm okay with that though. I'm in no hurry to die so young.

+1 I changed to this a long time ago and couldn't be happier with it.

Trust me, go 17/44. Stock is 16/43. 17/44 moves the revs down a little so that you don't lose too much acceleration that it hurts the fun factor, but increases high way riding 10fold. It'll allow you to cruise at 80mph without getting the dreaded buzz at 5k rpms. It'll cruise so smoothly at lower speeds that I forget to shift from 5th to 6th at times. It will still allow you to get to 120 really quick, and then 130 a bit slower. From there it crawl to 135 and then inch slowly to 137 indicated. At least that was the furthest I could push it before running out of straight away and needed to brake for turn 1. Given enough room I think it would top out at 138.

I commute daily (when it isn't down like right now) and 17/44 is really what the gearing should have come from the factory with.

I just did a quick query and I sold 66 of those 17/44 919 520 Kits last year and 8 so far this year. In that same time frame I have sold 6 Kits for the 919 in gearing choices OTHER than 17/44.

+1 on that 17/44 and the 520 kit.

if you're not interested in speed maybe don't worry about the 520 but it's definitely a noticeable difference.

That makes no sense considering 520 chain and sprockets are both cheaper and lighter than 530 parts.


I can sell an entire top of the line 520 Kit with DID ZVM-X chain for basically what a good 530 chain costs just by itself.

I will only throw in my 2 cents to say that the 17/44 520 kit is extremely uncontroversial.

Agreed on the 17/44 kit although I stayed with the 530 chain...

FWIW I've been running 17/41 since I bought my bike. 30k miles ago hard to pull a wheelie but great on the highway.

newbie question: what is the performance difference in the 530/520 debate? (with both having 17/44 gearing)

You save roughly 3-4lbs of rotational mass with a 520 Kit over a 530 Kit which greatly reduces gyroscopic precession

Well, if that isn't some very telling statistics I don't know what is !
Translated to %'s, it reads 92.5 % selected 17/44 and all other ratios combined only came to 7.5 %.
Good sample size and span of time.

I am ready to change the chain/sprockets too.. just checked and the P.O. installed a 17/46 with an 520 ERV2 (116 tooth).. It seems the 17/46 is about the same ratio as stock.. any thoughts on what the P.O was thinking with this set up?? and what can I expect from a 17/44 set up ??

I recently moved to the 17/44 gearing...

All the myths :P and benefits that are discussed are on this forum are true xD every single one of them...
The smoothness, the speedo correction, less buziness at higher speeds... The one thing I couldn't fully test is the better fuel economy, but i'm guessing less buzziness=lower rpm=better fuel economy.

The ONE thing that some MAY consider to be a negative is that you loose a bit of the bottom torque BUT its so negligible you can't really feel it around town.

All in all, it does feel like this is the gearing expected from factory...
