Welcome to the forum Dylan 
Honestly with the tiny power on 125 does not bother at all. The problem is you have so little power that in order to increase the low revs torque you will be also removing say 15mph from your top speed.
Otherwise you can change the front sprocket or the rear one or both.
Changing 1 tooth on front is the same as changing 3 tooths on the rear.
Usually we change the front one and make it with less tooths if you want more low revs torque. I have done that but my bike has top speed 136mph and more power. Means I have lost 10 mph only and added real oomph in low revs.
See this if you want to play with the options:

Note read gearing commander help well. When changing sprocket size you may need to change the chain lenght too.

Find sprockets that fit your bike. For example my front sprocket is JTF513
I have these Available Sizes
13, 14, 15, 16, 17, 18

JT is world biggest sprocket manufacturer.
Looking at the catalogue your brand WK is missing. That raises the next question:

Read your bike service manual.
