15/43,16/46 or Others

Hi,

Reading through the forum, many favour front/rear sprocket gear ratios of 15/43 or 16/46 combinations.
Just asking anyone tried 16/43? My chain change is coming up.

Thanks.

I just ordered this setup. I think it will suck in town, but I'm trying to get a 7th gear out of it. With a 16/43 5th gear will be the same ratio as the stock 6th gear. Using the gearing commander web site you can see the changes that this will bring. I need to get just a little better fuel economy for an upcoming Iron Butt certification. Bringing my fuel economy from high 40's to low 50's eliminates a stop. Mid 50's eliminates two stops.

i like 15/45 with a 70 series rear tire which adds 1/2" radius...poor man's ride height adjustment w/just a bit taller gearing.
16/43 would take all the fun out of the bike...

Umm... Extra height is not an option.

Yeah I know that this will not be a good ratio for any acceleration. But this is a dedicated setup for long distance riding. I have a 1500 mile in 24 hour ride planned and at 54MPG I would do 5 fill ups. I currently average ~46.5 or 7 fill ups, 48 takes me to 6 fillups. Each stop adds 20 minutes to my time. To cut 40 minutes using speed I need to go 78 rather than 75. As the limit on my ride is 70, this puts me into worrying about tickets territory. Oh and the faster speed puts me at lower mpg too. So eliminating stops is huge.

As you might imagine on a ride like this I don't spend much time at stop lights or carving up the twisties. Basically just have the cruise set at 75 and try not to fall asleep.

If you are not doing this kind of ride 16/43 should really suck. I plan on changing out my front sprocket when I'm not doing IBA rides.

I'll post back when I get it on the bike. Hopefully I don't roast the clutch in my testing.

Thanks for your reply, Lonerockz.
Decided to go 15/44.

For what it's worth 15/44 feels like the perfect ratio to me. You do not feel any loss of response when riding in the fun stuff and it takes just enough off during the dreaded freeway riding to make the bike feel comfortable. Been riding it this way for 10k miles now.

Bicyclebob,

Thanks for sharing your experiences using the 15/44 ratio.
It's reassuring to know someone out there has tried it and happy with the results.

Best Regards.

I put a 43T (stock sprocket from a ZX6R) on yesterday and I'm really liking it. Bike seems much smoother.

Sounds like the 43/15 which I have would work well for you. I think 43/16 would lug the motor, and you might have to push off to start, or slip the clutch excessively. That would definately be a "tallish" gear. The fact is, this is a close ratio gearbox, so your options may be limited. That said, I was surprised how much difference the 43 made in
the step up between the gears, not just the overall cruising in 6th. That plus it corrects the speedometer makes it a no brainer for me. Kawasaki should make it stock.

I agree that 15/44 for 4.54% taller gearing (or 15/45 with taller 150/70 tire like I have: ~5% taller) is just perfect overall. 16/46 (+6.67%) like I tried last year is already a tad overkill. 16/45, 16/44, and especially 16/43 would be ridiculously high geared and practically unusable... You're better off sticking to a front 15 which fits better than the 16. (16/46 is 6.98% taller than 15/46 stock)

Go with the tallest gearing - I want to see the results

Why not give the tall gearing a try. For what you are doing, it'll probably work great. Plus, I'd love to find out how you felt about it. I'll let you do the testing and I observe the results. In any case, let us know how it works for you.

I will definitely report back when I get it installed. 43T is due this week and 16T is due next week. Assuming I can get the front sprocket off...

I've been following this thread and been trying to find a steel 44t sprocket, I think the alloy Vortex type will wear out too fast for my needs. Who makes steel 44t sprockets for the versys? I keep finding 43t types, also would the 43t be too high gearing for 6000-10000 ft elevation riding? I live at 5200ft and 90% of my rides go up hill usually to 9500-10,000.

Thank you,
Nick

Gearing with 16/46 (+6.98%) is already plenty high... Why go all the way up to a sky high 16/43 (+14.1%) when you could try 16/45 (+9%)?
You can always sell the 43, or use it later with a 15.

Kimpex (Canada) sells "R.O.C." rear steel sprockets in 39, 40, 41, 42, 43, 44, 45, 46 and 47 tooth, as listed for EX560-A Ninja 650R. They're available through Canadian motorcycle dealers. I could always pick one up and mail to you in USA if you like... My 45T was about $37 CAD.
I certainly recommend no higher than 15/44 for your riding conditions.

Cause I'm hoping for a 9.5% boost it MPG. Moving me from 47.5 to 52. This puts me above the magical 250 miles per tank barrier. I will be attempting a 1500 miles in 24 hour ride. 47.5 MPG = 6 stops. 52 MPG = 5 stops. Have you ever done an Iron Butt style ride? Removing a stop is HUGE. ~20 minutes more time. I know it doesn't sound like much, but I need every advantage I can get.

Invader,
Thank you very much for the offer, my local dealer couldn't find a 44t in steel so he recommended going to a 16T front sprocket, I more or less gave up and had him order it. Will the 16T work as well as the 44T rear? I can stop the order if you think I made a bad choice. I'm an impatient idiot at times.

Well, 16/46 will give you 6.67% taller gearing, compared to 4.54% with 15/44. Are you replacing just the one sprocket? How many miles are on your chain and sprockets now? I could always have a shiny new 44T steel on your way if you like. I drive by my fine Yamaha dealer every day...

I got a credit card for the gas stations that you swipe at the pump, only use it for gas, I'm filled and on my way in less than 5 min.
Just a thought.

My intention "WAS" to just go to the 44T Rear sprocket, the dealer said he can have the front 16T in by the end of the week for $16.33 US. installation would cost $62.40. total $78.73. I'll leave the rear at 46T. I have 1350 miles on the bike, it just turned 5 weeks old. I"ll give this a trial run and see how it works for me. I intend to run it up a few mountain passes over 11,500 ft. to see how she runs. This past Sunday ( yesterday ) I ran over Hoosier Pass 11,541 and a couple of 9500 ft passes, 325 miles, avg MPG 56.85, avg speed 60+MPH. excluding gas and snack stops.
Can I take a rain check on the 44T if the 16T doesn't satisfy?

Thanks again;
Nick
