You also need to consider chain tension if you don't want to shorten or purchase a new chain. If you want drastic changes adjust both in the opposite direction. If your looking to increase rpm and gain torque decrease teeth in front and or increase teeth in the back; this decreases top speed. Larger sprocket in the front and or smaller in the rear and you increase top speed but lose torque. See if you can find dyno numbers on your bike and adjust the sprockets to the max torque and horsepower for the rpm range you ride in most. Example - Honda grom: I'm 300 lbs and needed torque and higher rpms, so I dropped one tooth in the front. This allowed me to get up hills and max out the rpms. I may have lost a couple mph of top speed but take off and hill climbing improved drastically. Most likely why the newer models went to a five speed. Front sprockets are cheaper and I would suggest adjusting by one tooth only. If you speed reads off wheel speed your fine otherwise you will need a tune for correct speeds. Check with gps to confirm.

Initial calculations are correct but later he is trying by guessing. Here is how to calculate and not guess and try: if you want to reduce rpm by 500 and keep the same speed you need to reduce rear sprocket teeth. 3500/4000 = 0.875 Then 42 teeth sprocket should be reduced to: 42x0.875 = 36.75 rounding it up to 37 teeth. Thank you.

The summary for what sprocket you might want to change to achieve different aspects of rpm power and speed --Front sprokect change bigger faster less rpm smaller slower more rpm bigger less power smaller more power --Rear sprocket change bigger slower more rpm smaller faster less rpm bigger more power smaller less power I recommend changing rear sprockets changing the front can put extra stress on the case drive gear bearing.

You forget t mention what happens to the torque, whis is important when you hit a slope. If you reduce the teeth on the rear sprocket by too much you will need to gear down more often. The magic is a combination of speed n power which the manufacturer has figured works best. And on the CBR, YOU WILL mess your speedo n odo.....so? Please cover these issues. At the end of the day it all boils down to your personal preferences.

Do not throw your money away changing the sockets. This will only make 2 results: 1. this will improve starting off (launching) 2. this will increase your RPM in top gear at highway speeds. Changing the sprockets is changing the final gearing on your cycle. Changing the final gearing means nothing. What really matters is overall gearing. Overall gearing is everything from the engine to the rear tire. Overall gearing is a affected by these areas: 1. Manual Transmission 2. Drive sprockets (final gearing) 3. Tire size (actually have to change rim diameter to change tire size much) It is a very common misunderstanding that changing the sprockets will mean you'll always have lower gearing. That is not true. You have a manual transmission. That allows you to have what ever gear ratio you want. If you like the power of low gearing then don't shift until redline for all I care. Shifting at redline is not what you really want unless you are drag racing. My point is you can decide how high you want your RPM to go before shifting. If you like low RPM for fuel efficiency shift early and keep your RPMs low. Once you get in top gear you can't shift up any more. That's why I say changing the sprockets will affect the RPM on the highway.

I'm dyslexic, and this was too many numbers for me to comprehend. So short and simple, changing my front sprocket is not an option in my case. However I'm upgrading my entire rear tire/ rim from spoke to mag rim. (Primarily because I keep bending the spoke rims) This forces me to change some mounting adapters, currently I have 42T on the rear large sprocket, Some of the longer steeper hills I can hear and feel the bike struggle to climb. But on flat straight road I'm averaging 22 mph at full throttle. So my dilemma is it wouldn't hurt to have more hill climbing power, but I'm riding on highway roads and can't afford to lose speed. I need to keep up with the slow lane traffic. Most the slow traffic is at least 35 mph. the adapter for the mag rim I'm looking at online is set up with a 36T sprocket. How will the difference between the 42T and the 36T help or hurt me? I am very limited what I can change. This is a bicycle with a 2 cycle motor on it. So I know I'm not any where near what a normal motorcycle has for engine ability.

No. If you want more torque, you need a larger difference between sprockets. Increasing the front sprocket is the same as reducing the rear sprocket, which gives you lower rpm for the same speed.

If youre spending a lot of time at walking pace, 1 smaller on the front and several larger on the back will help a lot. The revs will be lifted at low speed, so less stalling and generally less clutch work. You dont want to change too many on the front though... too small a sprocket on the front increases chain wear dramatically, and too big may jam the chain between the sprocket and the engine case.

He forgot about the chain links. If you have 110 link and you take a few off by having a smaller sprocket or adding because of a bigger sprocket, it will also affect the RPMs and Torque.. Tire Circumference Chain Pitch, it all comes in line.. Don't think the factory didn't take all this into consideration.. They have spent millions on engineers to determine what is good for the engine and drive train life.. When you mess with this always remember that your readjusting what the bike is optimized for.. For ex.. My GSXR track bike has the ratio of 18 39. This keeps me in 2nd as my accel, and 3rd to pull, 6 for top speed. Now It's a little slow getting there but I've gained 20 MPH for my top speed.. And great low end cornering accel. It allows me to make some great passes.. And always say WTH did you do to that bike.. LOL.. But over time, it has to be tuned more often, top end spark plugs and timing adjustments, IE.. Power Commander with all the options.. But when I started out, I had none of these items and I was just like you, clueless to the issues I was going to face.. IMO Keep your bike stock on the drive train for longevity, but if you don't care to knock off some engine life.. Just do a nitro setup and that will make up for all your worries.. IM just kidding.. Just take your time and don't get tooth happy.. More teeth equal more acceleration but less top speed, less teeth equal more top speed but less acceleration.. More teeth = more engine wear. Less Teeth = engine working harder and fuel timing adjustments along with other low end adjusting.. But have fun.. and Great VID.. THANKS..

Wrong - Period. Length of chain has zero effect on gear ratio. However, length of chain does effect rear wheel motion ratio. Shorten chain, moves rear wheel forward, makes bike more pitch sensitive, harder to transfer rear wheel weight but easier to track low speed corners, and effectively increases wheel rate.

Wrong... lower gearing = higher revs for the same speed. If you’re doing 100kph in 5th gear at 5000 rpm. Then go to 4th gear which is lower your revs will go to say 5600rpm to stay at 100kph. Then go to 3rd gear and revs will be higher again... so lower gear = more rpm for a given speed

This is full bs, you didn't mention in the end when you wanted to drop 500rpm, that if you wan't to calculate the front sprocket, you can't calculate the numbers in the same way you calculate the rear sprocket. If you wan't to find the 0,875 ratio in the front and wan't to drop 500rpm, you can't calculate it like 14 (14,875)/17 = 0,875!! Because the smaller front sprocket will give you more rpms! Why didn't you show this in the video? You can't always put the smaller number and dive it by the bigger in here. If you wan't to gain 500 rpm in rear, calculate 42*1,125. If you wan't to lose 500rpm in rear --> 42*0,875. If you wan't to gain 500rpm in front calculate 17*0,875 and to lose 17*1,125. Why not explain this!!?

Since when do you need to make a video to illustrate something that is so obvious? Even a child knows about ratios. Also, changing sprockets to reduce RPMs in the top gear is risky cuz maybe your little 125 wont be able to pull that tall "gearing" then if someone takes your bad ""advice", they may have then wasted money on sprockets, chain, labor, invested time... only to be disappointed. Even if it does work, at 8000 RPMs, if there is a strong headwind, it may slow the bike down to 7000 RPMs whereas with the 9000 RPM setup, it would "muscle" thru the wind better. This presentation is a gross oversimplification which tells me you don't understand much about motorcycles, gears, and sprockets.

gearingcommander.com is the site to go, and if you ride slow, gear low, if you ride fast, gear high

Very well explanation thanx mate and i think this also increases milage of your bike on highway as you are on low rpm compare to stock. actually this makes ratio taller and i personally like taller gear ratio cuz i ride on highways it makes your bike smooth like butter on high speed cruising

Once you find what new sprockets you want, how do you find the correct chain specs?

There's a limit what you can do with changing sprockets. Remember that you still have gears. And each gear has a certain ratio. If you increase the rear sprocket enough, you'l jjust make the 6th gear essentially a 5th gear.

Yeah a lot of people just sell sell sell, they forget about weight x ring rolls tire size ECT ECT hobb made weight punch it's not just go larger and it will have better horse more tourq. Case the guy with a life chain nicer roll less friction and less weight along with proper hobb and tire size you might just get burnt.

If increasing the numbers of teeth at rear end sprocket by 3 Teeth from the stock rear sprocket..do I have to change the chain as a whole or do I need to get a new chain with more linkage?

Awesome simple direct video. I'm trying to set up an electric motor to turn my snowblower chute. There's a huge wide toothed sprocket on the chute, I know now where to begin figuring out a proper drive sprocket for my motor so it's not too slow or fast! I know my motor's rpm, I'll count the teeth on the big sprocket and do some math v to figure out my rotation speed. Thank you!

I have a SWM RS500. The standard hearing is 13/47=3.6153846153846 . At general rule one at the front is equal to 3 at the rear. So my my gearing from the factory is pretty good. I just change the front to get a reasonable gear change. The big problem is the bikes ability to hold the gear load. Also it's easier to change the front sprocket out there on the track.. it's all to do with the stall point of your bike. If you own an old school bike that has plenty crank your bike will carry pretty stupid gear ratios. But unfortunately theses late model bike don't and most developed torqued thru engine management systems. I carry a 13 and 15..
