What is the ratio between front and rear sprockets?
We explain it all here. Your gearing ratio is, simply put, the ratio of teeth between the front and rear sprockets. This ratio determines how engine RPM is translated into wheel speed by the bike. Changing sprocket sizes, front or rear, will change this ratio, and therefore change the way your bike puts power to the ground.
How big are the sprockets on a motorcycle?
So let’s look at the factory set up on my bike, and see why it felt that way. The stock sprockets on my R1 are 17 teeth in front, and 45 teeth in the rear. Some simple math gives us the gearing ratio: 45/17=2.647.
Can a chain sprocket be changed to 15T?
For how to actually change your Chain and Sprockets, see the Changing your Chain and Sprockets FAQ . Some people find the stock sprockets on the F650 are unsuitable for their requirements. The most common change is to drop the front counter-shaft (C/S) sprocket from 16 teeth to 15 teeth.
Which is better a 16 or 47 sprocket?
Anyway the 16 wears faster than the 47, but that is no surprise because it is much smaller (top theoretic score for the 16 is 8 rev – see detailed observations below). The 15 scores bad with only 3 rev for the same tooth hits the same link.

What happens when you change the sprocket size on a motorcycle?
This ratio determines how engine RPM is translated into wheel speed by the bike. Changing sprocket sizes, front or rear, will change this ratio, and therefore change the way your bike puts power to the ground.

What’s the ratio of stock sprockets to mods?
By using these figures, riders are typically expressing how many teeth they changed from stock. On sport bikes, common mods are to go -1 in front, +2 or +3 in back, or a combination of the two. The problem with that nomenclature is that it only takes on meaning relative to what size the stock sprockets are.
This ratio determines how engine RPM is translated into wheel speed by the bike. Changing sprocket sizes, front or rear, will change this ratio, and therefore change the way your bike puts power to the ground.
Can you increase the rear sprocket for more acceleration?
you could increase the rear sprocket by two teeth or drop the front sprocket by one tooth to get more acceleration. Going with a larger rear sprocket could require a new (longer) chain. Replacing the front sprocket is typically the easiest and least expensive route.
When do I need to replace my sprocket chain?
When changing your sprockets due to wear, you will also need to replace your chain. The chain and sprocket relationship is best when the two wear together. Mixing an old chain with a new sprocket – or vice versa – will shorten the life of either. Not a good idea.
How many times does a rear sprocket have to turn?
In real laymen’s terms, this is the ratio of how many times the drive sprocket (front) has to turn before the driven sprocket (rear) turns once. So let’s assume you have a 5 tooth front sprocket and a 10 tooth rear sprocket. In order for the rear sprocket and wheel to rotate once, the front sprocket has to rotate twice.
How to calculate your sprocket’s final drive ratio?
To determine the final drive ratio, divide the rear sprocket size, say 49 teeth, by the front or countershaft sprocket size, say 13 teeth (like a new Yamaha YZ250F ). In this case, the Final Drive Ratio is 3.77 – the front sprocket revolves 3.77 times to make one complete revolution of the rear sprocket.
How can I tell if my rear sprocket is worn?
To inspect the condition of the sprockets, compare the side of the tooth that engages with the chain (to drive the wheel forward) with the other side of the tooth. Worn sprockets will exhibit a hooked wear pattern. In severe cases, teeth will become rounded or worn entirely off.
Can you change the sprocket on a Harley Davidson?
You can simply change your compensating sprocket to a 24, and see results. If you were to change both your compensating sprocket and clutch basket ratios…., A 37 tooth clutch basket, combined with the 24t compensating sprocket, it would make your gear ratio 3:37, which is a torque improvement.
