Motorcycle Gearing Changes Explained | MC Garage

Want more acceleration or better fuel mileage from your motorcycle? It might be as easy as swapping out a sprocket. We’ll tell you everything you need to know about changing the final-drive ratio on your bike in this video from the MC Garage.
--
When we talk about gearing, we’re referring to the final-drive ratio, which you get by dividing the number of teeth on the rear sprocket by the number of teeth on the front, or countershaft sprocket. This figure represents the number of times the front sprocket has to rotate to turn the rear sprocket, and ultimately, it determines how engine rpm translates to road speed and how much torque there is at the rear wheel.
The Different Types Of Gear Ratios
Before we get into the nuts and bolts of it, let’s talk the lingo. When someone says that a bike is geared “tall” or “high,” that means you’ll get a higher top speed but at the cost of acceleration. If someone says that gearing is “short” or “low,” that means better acceleration but a lower top speed. Here’s the confusing part though. A larger gear ratio-say, 3.10-correlates to shorter gearing, while a low number-like 2.70-represents taller gearing. It all goes back to how many times that front sprocket has to rotate to turn the rear sprocket and the wheel.
The good news is that while crunching numbers to compare ratios is helpful, it’s not necessary. All you really need to know is what your bike’s current gearing is-it’s printed right on the side of the sprockets-and then figure out how you’ll need to adjust the tooth count to change your bike’s performance.
If you want better off-the-line acceleration, say, because you ride a small-displacement bike or predominantly ride in the city or really tight canyons, you’ll want to lower your gearing by either subtracting teeth from the front sprocket or adding them to the rear sprocket. If you want to get better gas mileage and net lower rpm as you cruise down the freeway, you’ll want to either add teeth to the front or subtract them from the rear.
For the most part, riders tend to gear their bikes shorter since many motorcycles today come with excessively tall gearing. But even if a bike feels like the gearing is way off for the way you ride, you probably won’t have to change the tooth count much to notice a big difference. In general, people will change the front sprocket by one, maybe two teeth, and alter the rear by perhaps two or three teeth at maximum.
Do I Need A New Chain When I Change Sprockets?
If you change your gearing, even by just a tooth, you’re changing the diameter of the sprocket and it’s going to affect your chain slack, so make sure you readjust the chain tension. Most minor gearing changes of just a tooth or two can be accounted for with the available adjustment at the swingarm, but you don’t want to mess with your wheelbase too much, and if you’re going big on the rear, you may find that you need a longer chain. Also, if you’ve got a decent amount of mileage on your drivetrain, you’ll want to replace everything as a set so it all wears evenly. Throwing a new sprocket at a worn chain is going to chew it up in a hurry.
Gearing Changes And Your Speedometer
Another thing to consider when changing your gearing is how it might affect your speedometer. Most bikes register speed off of the transmission, so altering the final-drive gearing is going to screw up the math the ECU is doing. If you have an older bike with a front-wheel speed sensor you're in the clear, but otherwise, you might want to consider getting a SpeedoHealer or a similar calibration device.
What Sprocket Should I Change First?
Now, if you're on a budget or just want to experiment to see how a gearing change affects your bike, the cheapest and easiest thing to do is to swap out the front sprocket. Front sprockets are cheaper, for one, at about $20 or $30, they're held in place with less hardware, and a change of just a single tooth alters the ratio more than a single tooth on the back wheel. Rear sprockets cost more, and you have to remove the rear wheel to replace 'em.

I replaced the stock 16t front sprocket on my 07 GS500F with a 14t sprocket and it makes a big difference in how the bike accelerates. I love this setup because I do more sporty riding than highway riding

[@davidjames1684]

On my 2004 Kawasaki ZX-10R (17-39 stock sprockets), I went with -2, +11 (15-50 sprockets) and not only did those look cool, it made the bike MUCH more fun at lower speeds since I could get at the power MUCH quicker without having to go at license losing speeds. When not riding aggressively, I could easily shortshift all 6 gears at legal speeds but when I wanted to hammer it, I had all 6 gears in the speed range of the stock first 4 gears. The bike just "ate up" each gear quickly but still had a theoretical top speed of close to 150 MPH. Lots of fun. The 15-50 sprocket combo is a 3.33 final drive ratio so to get that with the stock 17 tooth front, I would need 57 teeth (3.35) which would have made it look like a stunt bike sprocket. Reducing the # of teeth on the front sprocket somewhat "hides" that it is geared down but a rear sprocket change is kinda obvious.

Changing my final drive from 2.14 to 2.1333 repeating is improving my fuel economy, increasing top speed and since my rear sprocket is bigger my acceleration shouldn't be hurt so much

[@crisaraya2558]

you really picked the best bike for this example, as a former owner of a versys, I always thought the gear ration was too low. is too aggressive especially in the city. great video, would have been nice to see real-life results in the versys to see the top end speed change gain in sacrifice to a bit of torque ( which in my opinion there is plenty in that bike)

[@jay_321]

Another factor to consider when changing the front sprocket is chain life. Going taller in the front extends chain life significantly. Going shorter in the front decreases chain life significantly.

[@Aaaaa69999]

Jay _ yes that's why you always increase in the rear vs decreasing in front, even though ari recommended the opposite

[@JJ_ExMachina]

Well I went 2 down on the front and 3 up on the rear... OF my 2005 Triumph Daytona 650 about 20k miles ago... Chain and teeth are still just fine, yes the chain is getting near the point I will want to change it (measured the "stretch"), however it is still well within safe limits. I don't do any sort of wheelies... I do ride aggressively, and I purchased to spec parts. SO while I agree it does put added wear on the chain to do what I did, it's NOT going to wear it out that much faster then if you didn't do it. OR at least in my case (I take really good care of my stuff), it has not really effected the longevity of the life of the chain.

[@B10401]

It's good to keep in mind that shorter gearing mainly helps off the line, as you can just be in a lower gear when up to speed, and you'll have the same acceleration at a given rpm and mph. If you're always going slow then shorter gears can help you stay in the power band, though. And if you have a sport bike that's geared ridiculously tall, and can go 90+ mph while lugging the engine, then there's no downside to going shorter.

[@B10401]

A good tool for doing the math is gearingcommander,com. if you want to know how big of a change it will be.

[@Bursar60]

I have a versys 1000 and torn on whatd be better. 1st gear zip seems fine, its more I hate loss of grunt in 6th gear going 60-100mph. Like feels like a bigger change 5-6th than between other gears. So making passes on highway I find myself wanting to go to 5th. Loss of mpg would be sad but feels like wasted gearing when im not running it up to 150mph and even doing 80/90 im only at like 3500/4000 rpm Though as a new rider I may just be scared of keeping it in higher revs. Other than moments of flooring it. Even going fast fron a stop Im enjoying fast up shifts with barely a release rowing up thru the gears at 4500-6000 rpm. Seems better than hitting second and reving it up to 8k hitting 60 then shifting up 4 gears in one go.

[@SpottedCreeper]

Great video as usual Ari. Would have been nice to show some stats of the differences going up/down teeth on that Versys. Eg. we went up two teeth on the rear and top end dropped from 133 mph down to 1xx mph, but the 1/4 mile time improved from xx seconds to xx seconds. And maybe some fuel consumption figures. Get Zack to do a commute on the standard size sprocket and then change it (up or down in teeth) and do the commute again and see how much it affects consumption. Keep the MC Garage vids coming, I'm always learning something new from them!

[@amerpaisa6920]

Looking for stats:www.gearingcommander.com

[@SpottedCreeper]

Nice link, thanks!

[@888jackflash]

Changing the front is the easiest and best. YOU DON'T NEED MUCH. One tooth is a lot. My SV1000 was too tall so I DROPPED a tooth up front; my old Bandit 1200 was too SHORT (it's a 5- speed), so I went UP a tooth. Both brought the bikes in-line with how I ride. Be careful though! 1) make sure you have enough physical ROOM to increase front sprocket size... and 2) watch your chain slack on the swingarm marks. You could easily make your chain too short or long. PS - I never worked on a bike where you could "easily" swap front sprockets without at LEAST removing the rear wheel.

[@adamrubinger2644]

Another thing to think about is rebound inertia. Similar to the power loss of a piston having to travel in the opposite direction before more power can be created by it. Think about your chain having to whip around a tiny front sprocket vs being able to more slowly/efficiently roll around it. So having a bigger front sprocket and also a bigger rear sprocket may be worth trying. Also at the same time you may, depending on how big you go on either, will equate more sprocket and chain weight (if you need more chain links) and more rotating mass, unless you are running aluminum vs stock steel. Without a crap ton of math making it a perfect science it's another consideration of gear changes to think about/play with. Especially for the rider who has three or four fronts and eight or ten rears. I've gone back and forth with a few of these myself on dirt and street with interesting results. Lemme know if anyone tries it and how it works out for you.

[@LRS7B]

*Sooooooo…* Does adding teeth make each gear rev out slower but also for longer *??*

[@seinfeld11123]

actually did this last week. I wanted taller gearing on my R3 as its always revving its tits off. so I worked out I got 8% higher top speed / loss of torque. So to combat that I got myself a high end X ring chain that recovered said lost torque. Win fricking win!

gearing is one of my strongest expertise, gearing choice in road race kart racing is key. on my Vulcan 650, i swapped the motor sprocket to one more tooth, since im light weight and the motor revvs high, this was super beneficial. adding a tooth to the motor was a bigger difference than taking away a tooth from the axle.

[@shadevelt]

so you have longer gears?

[@JReed305]

The easy way to change the final drive ration on a shaft drive is to change the aspect ration of your rear tire. Say you have a 190/50/17 on the rear and you want to get a taller final drive, switch to a 190/55/17 and you get a similar effect as changing a rear sprocket by one or two teeth.

[@Daschickenify]

The problem with that is the increased weight of the bigger tire, as well as little availability of different motorcycle tire sizes. The number of tire sizes for motorcycles is miniscule compared to car tires. Plus the cost of a new tire easily surpasses different sprockets, unless you needed a tire anyway..

[@teagan73191]

Noob question : Does changing gearing affect where the powerband is? Like if you gear a sportbike down for more torque and less top end is it effectively moving the power band down the rev range? Or does it apply increased acceleration across the whole rev range and not effect the power band specifically?

[@hisride]

No, powerband is to do with the engine itself and how it makes power. Gearing just affects how that power is put down. Easy to think of if you use a bicycle. When in a high gear (ie low gear ratio) its hard to get the bike to accelerate quick, but in a low gear it is super easy and you can even wheelie if you are not careful. The powerband (ie your legs) never changes, just how quickly youre in it and what affect it has on turning the wheels. So in effect, shorter gearing will make the bike feel more torquey, but you will go through the gear a lot quicker and ultimately have less top speed. hope that helps!

I'm now thinking about a thing. When getting a higher ratio, it's less expensive and easier to change the front sprocket. But, by changing rear sprocket, is there a gain with lowering the rotating mass and diameter ? Wich can result on same gain that front sprocket but with little acceleration gain (and again more mileage) ? Or is that negligeable ?

[@RR-xb7dl]

Great video. I have a 2009 CBF1000A and I need to replace my chain and sprocket soon. I am considering different sized sprockets if they would increase the acceleration from start off because the CBF1000A's first and second gears range are so low they really hinder a good take off. I have ridden some other bikes which effortlessly accelerate from zero to say 60km/hr in first gear. How much of a high end speed reduction is there by going with a shorter gearing?

Changing the sprockets also affects the anti-squat characteristics of the bike. This is something to keep in mind with this modification.

[@stmboat]

say more, im not familiar

[@Reihe_sechs]

One of the factors that influences anti-squat in a motorcycle is the angle between the chain and the swingarm. When you place a smaller countershaft sprocket and a larger rear sprocket this angle increases. This way the motorcycle gets more anti-squat. It works the other way around too, so when you place a larger countershaft sprocket and smaller rear sprocket the bike tends to squat more under acceleration.

[@stmboat]

Makes perfect sense and I learned it today. Thank you.

[@ashwinprakas606]

Not quite, in certain scenarios where you're riding a smaller displacement motorcycle on tighter roads, shorter gearing can actually improve gas mileage. Running with 14/36(stock) sprockets on my 220cc motorcycle I'd open the throttle more at lower gears to maintain a decent speed and prevent knocking whereas now with a 14/40 setup all is well and I roughly do half the RPM's and throttle input to maintain the same speeds.

Just bought my l6 gsxr 1000 want to improve acceleration and reduce high rpm any recommendation for gear ratio ?

[@pandeysiddhartha]

Hey Arai, love your easy and simple to understand videos. Though would like to know how to judge as to what no.of teeth we can increase or decrease on a certain bike?

[@willem18241]

Next video: How do you keep that drivetrain so clean.

[@AriH211]

We've done that video ;)

[@GT6SuzukaTimeTrials]

Keep the bike in a garage and never let it get rained on.

I’ve been riding my 2007 KLR 650 with stock gearing for years. I decided to go down a tooth on the counter sprocket this spring and boy oh boy, it’s pretty damn nice. While taking it on the highway now is fucking terrible, taking it around town is pretty awesome.… And that’s from just one tooth on the front. It’s not a super major change but it’s pretty noticeable. I’d love to try to get more torque-y next year. That being said, it’s performance at highway speed is so irritating that I would suggest swapping the sprocket back out if you’re going on a significantly long ride for a few days. In fact, I’m going on a multi-day ride soon and I bought a new stock counter sprocket to put in. If you don’t take your bike out on the highway very much but you commute, I would consider doing what I did.

Note to the editor: Ari looks warm. Consider adding a gel the main light so it's closer to the background color temp? Great video as usual!

[@AriH211]

That's because it was 90 degrees in the shop when we filmed ;)

[@mr.niceguy1647]

what about chain size, there are kind of chain size ex : 415, 420, 428, 512. is this give effect to motorcycle power transfer??

[@CollinMac96]

TWO questions 1)What if you drop a tooth in the front and go up teeth in the rear. Will anything change? 2) and is there any benefit on going higher in the front vs lower in the rear?

[@CollinMac96]

Thanks ☺

[@noahmalendres6460]

Can u put a small front sprocket and big rear sprocket or only one or the other and would a 4.07 gear ratio be good for acceleration

[@joelgracelin3313]

love your videos .it helps me learn a lot about my bike . please make videos often

[@KingSlayer836]

I need more acceleration. But not as much as a stunt rider needs. How much teeths should I increase on my rear sprocket or decrease on my front sprocket?

[@patrick00755]

Question I have 16 front 42 rear on my kz650 but I want to gear up for more top speed. What would you recommend? Thanks

[@DmanGuitar327]

15 /45 is exactly what i have w my 00 gsxr 600, had 16/46 2.87 fd to 15/45 3.00 fd n man what a difference

[@sandicroatia1573]

Great videos. Thank you very much. What do you think about husqvarna 701, would love to have something in between speed and acceleration, maybe a little bit to the acceleration side. I was thinking about 15/45. What is you opinion, thank you very much. Greetings from Croatia

[@brianbrooks5947]

So what's the real difference from changing the front compared to rear. What is the difference in characteristics

[@TheAvnero2010]

If I take 1 down in the front sprocket and take 2 up in the rear, what difference those it make in the chain length?

[@adrianr4971]

Hi there , can I ask if you have any how videos on auto cam chain tensioner.... In particular for a Yamaha tw 125 but I guess almost any is the same.

[@sun6v546]

Very Good job , Mate .........Thank you .👍👍👍👍👍👍

[@naveenvarghese7463]

Hi, i would like to upsize my front sprocket from 14 to 16 teeth, and my bike currently runs with 116 link chain, should is upgrade the chain too or will it works with the same 116 link?

[@_davidsuciu]

By going 2 teeths more in the back , do i need to change chain ? What about adding that speedo helper , would the mileage difference be noticeable or nothing to worry ? Thank you so much

[@timothy9596]

Excellent vid as usual Ari.

[@ginogallegos8106]

Is there a difference in changing the gear ratio on the front or on the back, other than budget, when you get the same result? Let's say 16-48 or 15-45, which gives me 3.00 Gear ratio on both. What will result in better performance? Subtract 1 on the front (because engine speed) or add 3 on the back. (ok, I am thinking in weight savings if I go for a 48 aluminum) or it does not make a difference. Thank you

[@charliegutierrez8728]

I have a 82 Yamaha xj 550 and I don't want to force the motor to rev high at a higher speed. What would be the best combo to lower my RPM
