Does anyone know where I can get a rear sprocket for a mikilon m96 bike. I've changed the front from a 12 to a 14 but the bikes still way way too low geared for the road (its buzzing at 45 but still pulling like a train). It has a rear sprocket with 36t 520 size with 5 mounting bolts. Failing that does anyone know what the jap eq. bike would be? Would love to improve the gearing feels like it just zips up to 5th and thats it.
sorry worded that wrong was after a 36t sprocket:icon10:
If no-one comes up with the Jap equivalent from which that bike is cloned, you'll have to wade through the vast range in JT Sprockets until you find the right one. You need data such as chain size, this you already have (520), the size of the middle hole, the number of bolts and their size (probably 6 x M8), and the pitch circle diameter. This is the diameter of the circle in which the bolts are drilled.
Example of what you'll find on that site. This is from an XT250 Yamaha:

thanks I am looking on jt but it may take some time.............
the sprocket has a center bore of 117mm and 5 allen bolts securing it to the hub prob about 130mm(not measured this prop. yet)
will let everyone know if I do find it
Hi, thanks for the info. I also have one of these bikes and reckon it would be great with a couple more gears! like maybe a 6 7th and 8th. 1st is ridiculously low so plenty of room to modify.
Can you tell me where you got the front sprocket and its model/make?. Also did you get a rear sprocket? Would appreciate similar details for that too.
I have the same bike and had the same problem :eek2:
After searching for a while I was unable to source a rear sprocket that
would fit, I then ordered a blank 38T sprocket from a local bike shop. It came without any holes in it so I took it to a engineering shop and gave them the old sprocket so they had the correct sizes to cut the center hole and the mounting holes, and it works like a dream. The bike is also much better at top end, I wanted to fit a 36T but could only find a 38T b ut still wort the effort. :icon10:
Sounds expensive - customm machining. mind if I ask how much?
The sprocket was about $35 US and the engineering shop charged me another $35 US :popcorn:
Thanks sounds reasonable. I live in rip-off Britain tho' so it will be twice as much here no doubt!
Hi,
Just found out that the rear engine mountings on my m96 125sb are cracked and broken off. Wonderedf if you have seen the same thing on yours?
I have had the same problem, it seems like the vibration from the engine breaks the engine mounts.
Wonder how hard it would be to make rubber gaskets for the engine mounts?
My old Jailing 150 snapped the top engine mounts and I often though a nice solid piece of rubber between the mount plates and the frame would have helped that issue.

Hi,
Im struggling to get a frond sprocket. YOu said you replaced yours with a 14 tooth. Can you tell me the mnake and model or part number so I can track one down here?
Hi there ,
i was just wondering if anyone had any joy finding any manufacturers that make sprockets ( front and back ) for a mikilon 125SB - mine seems to only hit abouit 62 and top out so i am looing at the gearing as a possible tweak .
if anyone has any info it weould be greatfully received .
cheers

Still looking and trying to get a JT sprockets catalogue to match up sizes. Their site only has search by bike model not by chain or sprocket dimension so hard to find anything that way. Thats why I'm after their printed catalogue. I'll post if I find anything.
