Gearing

[beardyweirdy@me.com_imp]

Has anyone swapped out their front/rear sprockets on a 2014 6 speed model?

I've searched and found a few people looking to lower the revs at motorway speeds on 5 speeds, but I'm looking to go the other way.

On a run the other day, track obviously, I was getting 100 at 6000rpm in 4th. It's doing a touch off 90 at the start of the red line at 8500rpm in 2nd.

The way it's geared it would top out in 6th at.... well, I don't know, as I haven't really got the maths to work it out, but silly speeds.

I actually only use 6th as an overdrive. Just a lazy gear for the motorway, when 2 up.

It did seem to me that lowering the gearing might just make better use of the power for my sort of riding. I like using the gears. As it is, 70 is about 3k and the motor is hardy turning. I've got a few revs to play with and thought it might 'brighten up' the bike.

Anyone gone that way on a 6 speed and if so, did it work for you?

My bike has an ECU Flash, PCV, TSR Air Intake, Air Funnels, and a cat free 4 into 1. I've also lightened it some.

Thanks

I'm new here, having just bought my bike last Saturday..but changing gearing for better acceleration is very common on almost every motorcycle I have ever owned or known. Doesn't matter, dirtbike, streetbike, etc. I've even owned certain cars that changing the final drive was popular.

On a bike many people opt to go with one less tooth on the front sprocket, as that is easy and cheap to do. Be aware that making the chain turn around in a tighter space can cause it to wear faster. I prefer to put on a larger rear sprocket, but they do cost more, more work to replace, and many times will require a longer chain. The rear allows great fine tuning of the gearing though, as 1 tooth on the front will have a bigger jump in ration than 1 tooth on the rear.

So, I've only ridden my CB for about 100 miles so far, but I agree with your assessment- a little more aggressive gearing would probably be beneficial. Revs are plenty low enough in 6th, even on the highway.

Even though it will perk up the bike a bit, it won't change it's overall attitude. What it really needs is more aggressive cams. I haven't looked at the specs yet, some bikes like more duration, some more lift, some both. I've done cams on numerous bikes and cars and that is where the main change in power and 'wake up' comes from. Of course they are not as popular as exhausts or intakes on just about any vehicle because of cost & work involved.

You just may be a CB1100 gearing pioneer. I haven't heard of anyone on the forum changing out their sprockets. Of course, I may have missed it. It seems most are much more relaxed in their riding or have other bikes more traditionally suited for your type of riding. Sounds like fun though. Good luck!

Most of the gearing changes I've read about on the forum have been on 13's going larger on the counter.

If anyone has changed any sprockets for more acceleration on a 14 model 6 speed, I suspect it would be MotoGeezer. I think CIP geared down his 2013 5 speed.

yes

here is the deal

if you have changed gearing on other bikes and know what you want then of course you will go for it

if you have never done a gearing change then i will say that in most cases it seems like a good idea but the results are not usually very pleasing

if you gear up, then the bike will harder to get moving off the clutch in first gear but of course less rpm at road speed

if you gear down you will have more perceived acceleration but the bike will be spinning faster and feel overworked or strained with more vibes at road speed

honda have done a good job at sorting these bikes

that will sort it all out for you

i recently used it to come up with the perfect gearing for me 2012 gsxr750

took me three track days to get used to the new setup but it is a huge improvement

lap times are the same but control is much better

also I can run a gear higher in many places now and still have the torque i need

from what you say it sounds like you want that

i also ride my 2013 cb1100 as you said with high rpm and like to keep it in the power

Oh dear.... Ulvetanna, you've done a bad thing.

I was supposed to start tiling the bathroom this afternoon but that Gearing Commander app. is just too darn useful, and slightly addictive.

Thanks for that, I'll report back with what i find...
The software says it'll top out on stock gearing at 183.7mph at 8500rpm. Even with the all the go faster mods it would take a long straight downhill of epic proportions to ever hit that... and if there were such a downhill on this continent, I'm not sure I fancy trying it.

Fiddling with the ratios tho, 17/43 looks tempting.

Must get on with the tiling.... wonder what 17/44 would do... ;-)

[beardyweirdy@me.com_imp]

Fitted 17/43 this afternoon. The run thru town, back from the workshop was great. Revs much more in the zone. She feels much perkier and responsive. I'm off for a longer run tomorrow and will report back, but so far a solid improvement for me. Very lively!

[beardyweirdy@me.com_imp]

Well, a longer ride thru the city confirmed that I've done a very good thing. Two up in town the gearing is much better. Just seems to sit well at town speeds, where 2nd and 3rd gear are being used. One up on the way back and she's much zippier of the lights. It wasn't slow before, but it feels better. I've still got to take it out on the open road. It'll be interesting to see if crushing speed is effected much.

The bike tops out @ 140MPH with wind resistance. To get the most power you want to max out speed in 4th gear. On the 13 model which is almost identical due to the different rear sprocket on the 6 speed you want to go up 1 in front and down 2 in back. This will put you @ 1st 60, 2nd 100, 3rd 127, and you'll max out fourth @ 140+ before you redline. On a tight track stock gearing may be better but on a long track this set up will get you to top speed much quicker due to a lower gear ratio of being in fourth instead of 5th or 6th if you decide to go the other way with gearing.

Edit: Kev, Check out post # 25 in the link below. Gives you a good comparison between gearing 0-100. You will not lose a step off the line and be able to stay in your power gears 2nd and 3rd longer.

A few months back I dropped the front 1 tooth. Actually got a tiny bit better mpg. Operates more in the power band at cruising. Pepped it up a bit around town, which was what I was looking for.
