- How To Choose Motorcycle Sprocket and Chain
Motorcycle sprocket wheel is divided into the active sprocket and the driven sprocket wheel.The driving sprocket wheel is arranged on the output shaft of the engine buy the spline.The driven sprocket wheel is installed on the motorcycle driving wheel.The chain passes the power from active sprocket to the driven sprocket wheel.The active sprocket wheel is usually smaller than the driven sprocket wheel,it can reduce the speed and increase torque at the same time.
A simple sprocket change can give your motorcycle more power. It's an easy job to do, but the hard part is figuring out what size sprockets to replace your stock ones with. We explain it all here.
1.When choosing a sprocket, what does 520, 525, and 530 mean?
Basically, this refers to the thickness of your sprockets and chain (called the "pitch") 520 is the thinnest and lightest of the three, 525 is in the middle, and 530 is the beefiest. Many OEM components are 525 or 530, but with the strength of a high quality chain and sprockets, there is usually no danger in switching to the lighter 520 setup. Important note: always make sure you install components of the same pitch; they are not compatible with each other! The best course of action is to buy a conversion kit so all your components mate perfectly, like the Vortex 520 Conversion Kit.

2.Do I have to switch both sprockets at the same time?
This is a judgment call, and there are differing opinions. Generally, it is advisable to change sprocket and chain components as a set, because they wear as a set.However, in many cases, it won't hurt to change one sprocket (usually the front.) If your chain is relatively new, it will not hurt it to change only one sprocket. Considering that a front sprocket is typically only -30, I recommend changing it as an inexpensive way to test a new gearing ratio, before you take the plunge and spend the money to change both sprockets and your chain.
3.How will it affect my speed and speedometer?
It again depends on your ratio, but both will generally be altered. Since most riders opt for a higher gear ratio than stock, they will experience a drop in top speed, and a speedometer readout that says they are going faster than they are. Conversely, dropping the ratio will have the opposite effect. Some riders purchase an add-on module to adjust the speedometer after modifying the drive chain.
4.Is it easier to change the front or rear sprocket?
It really depends on your bike, but neither is typically very difficult to change. Changing the chain is the most complicated task involved, so if you're changing only a sprocket and reusing your chain, you can do whichever is most comfortable for you.
An important note: going smaller in front will loosen the chain, and you'll have to lengthen your wheelbase to make up for it; going up in the rear will likewise shorten it. Know how much room you have to adjust your chain either way before you elect to do one or the other; and if in doubt, it's your best bet to change both sprockets and your chain all at once.
5.There are aluminum and steel rear sprockets, which one should I get?
Traditionally, aluminum sprockets are light but wear quickly, and steel sprockets are durable but very heavy. These days however, most aluminum sprockets are hard anodized which dramatically extends their life, and there are many new super-light steel sprockets with the strength of steel while being almost as light as their aluminum counterparts. It ultimately comes down to preference, but generally aluminum is a little lighter and steel is a little more durable.
