Which sprocket is faster?
Substituting a larger front or smaller rear sprocket lowers the ratio (sometimes called “taller” gearing), resulting in more speed for a given engine rpm. Likewise, a smaller front or larger rear sprocket gives less speed for a given rpm (“shorter” gearing).
Will a bigger sprocket faster or slower?
Gearing up adds more speed and decreases the final drive ratio. You can gear down by using a larger rear sprocket or a smaller front sprocket. Gearing down reduces speed and increases the final drive ratio. For more bottom end and faster acceleration, use a small countershaft/front sprocket or large rear sprocket.
What does putting a bigger rear sprocket do?
Gearing down by installing a larger rear sprocket (like with our YZ example) increases the final drive ratio and reduces top speed, but can increase acceleration. Gearing up, like with a smaller rear sprocket, decreases the final drive ratio and adds more top speed to your motorcycle or ATV.
How can I make my bike sprocket faster?
To increase low end power, you should increase size of rear sprocket or decrease size of front sprocket. To increase top speed, you should reduce size of rear sprocket or increase size of front sprocket.
How can I make my 125cc dirt bike faster?
Upgrade your front, rear or both sprockets for increased power-band control. Motorcycles with 125cc engines lack top speed compared to larger displacement engines. Purchasing a front sprocket with less teeth than stock and a rear with more teeth than stock can help.
How do you increase torque on a motorcycle?
How to Increase Motorcycle Horsepower
- Increase Your Bike’s Air Intake.
- Upgrade Your Exhaust System.
- Plug-In an Aftermarket Tuner or Reflash the ECU.
- Install a New Jet Kit for the Carburetor.
- Modify Your Ignition.

How do you calculate sprocket speed?
The easiest way to calculate sprocket ratio is to count the number of teeth on both the driving and the driven sprockets and divide the first by the second. This ratio tells you how many times the driven sprocket turns for every revolution of the driving sprocket.
What is the power of Honda ANF 125 Innova?
The Honda ANF 125 Innova model is a Scooter bike manufactured by Honda.

What is the top speed of Innova 125I?
Honda ANF Innova 125i: The effective cub. Engine: The 125 c.c. engine delivers smoothly, in a linear way, however the major feature is the long gearing. The speed of 20 Km/h is reached instantly, 40 Km/h fast, 60 Km/h adequately, 80 Km/h slowly. Above that, top indicated speed of 107 Km/h needs some time to build.
Is a 125 Innova worth it?
You can say many things about a 125 innova; it’s not cool, it’s not fast, it has a poncy tank, it’s wobbly etc etc BUT it has so much soul and for me it is the ultimate expression of freedom. No matter where you end up in life you can always hop on an innova and get around. 01/01/2000 00:00:00 UTC Ruskie said :-
Is the Honda Innova a good bike?
I brought my Honda Innova one year ago, and having not been on two wheels for over ten years, find it a superb little bike, and a great development on my 1979 C70 which is still in my garage. I did intend to use it in all weathers, but it is far too nice to be abused, and use it mainly for work when conditions permit.
How much horsepower does a crf70 have?
3.5 to 3.6hp out of the box. Put on a pod filter, put a thrust nozzle on, rejet the stock carb, 4.2hp on the cheap.
Where are Superlite sprockets made?
Superlite sprockets are made in the USA and give you the best performance with the least hassle.
How do I know what size sprocket to get?
This is determined by the the number of teeth on the front sprocket, compared to the number of teeth in the rear sprocket. For example, a motorcycle with a 17-tooth front sprocket and a 45-tooth rear sprocket would have a ratio of 2.65 (45 divided by 17 = 2.65).
How do I get low end torque on my motorcycle?
A smaller sprocket on the front, bigger on the rear will take-away top end speed and increase bottom-end torque. A bigger sprocket on the front, and smaller on the rear will increase top end speed and take away bottom-end torque.
What size sprocket is best for wheelies?
If all you want to do is wheelie, then go something like 12/50…you’ll wheelie in every gear…but you’ll only be able to do 50mph.

Most part numbers are available in 520, 525 and 530 pitch with a variety of tooth sizes to choose from.
How does sprocket size affect torque?
Changing your rear sprocket won’t give you more mid range or change the engine power curve in any way. It will alter the torque at the rear wheel at all RPMs. The bike should accelerate faster through the gears but you will also loose out on top speed. You don’t need to get dyno tuned just for changing a sprocket.
What tooth sprocket should I use?
So, the bottom line is, what are you trying to achieve? For more bottom end and faster acceleration, use a small countershaft/front sprocket or large rear sprocket. For every 1 tooth that you change on the front sprocket is like changing 3 to 4 teeth on the rear (and that’s true for higher gearing ratios, too).
Which bike has best low end torque?
Duke 390. Start the bike, put on the first gear and release the clutch.
