A flexible chain and sprocket kit where you can choose teeth and chain lengths!
With the help of our gear guide you can easily see what standard sprocket and chain length that sits original on your bike.
Select the corresponding sprocket and chain in the list below.
This is a combination of a Japanese D.I.D chain and sprockets from the worlds largest: JT Sprockets!
Reinforced chain with high quality, solid chain rollers. Suitable for 125cc roadbikes.
Supplied with split link.
The chain's average tensile strength is 33 (kN) and 5250 (LBS)
All JT's gears are CNC - machined from high quality C45 steel , providing greater precision and durability.
After milling, the gears are coated with a hard - anodized coating that prevents corrosion which extends the life and also gives a nice finish.
To select the right chain and sprocket:
Changing the size of the front sprocket or the rear sprocket is a very easy and popular way to change the nature of your motorcycle.
1: To get better acceleration - Change to a smaller front sprocket and / or a larger rear sprocket.
2: In order to get a higher top speed - Change to a larger front sprocket and / or a smaller rear sprocket.
You notice a similar difference in changing one tooth front that by replacing three teeth rear.
On most motorcycles you notice a big difference in changing one tooth front, and it's recommended to try things in small steps.
To maintain the correct angle on the chain you should distribute the changes between the front sprocket and rear sprocket as one tooth front + 3 teeth rear.
When you change the size of the sprockets, you also need to change the length of the chain.
On almost all motorcycles you can switch to one tooth bigger or smaller front or rear sprocket, but still retain the original length of the chain.
At changes of more than one tooth you often need to change the length of the chain , then the following is a good rule to use :
If you change plus 2 teeth larger sprockets , you need one link longer in the chain .
All chains increase by 2 links at a time, so you may need to cut the chain.
There is also a chance that you can avoid having to cut, by adjusting the axle blocks at the wheel axle.
