03-05-2009, 08:46 AMIts a 428, I had already checked and there are no tab washers. I am not sure if the sprocket is held in place by four bolts coming from behind the sprocket or if they are studs. Anyway I will check at the weekend and let you know. I'll upload some photos early next week.

forchetto,
Did you change the front sprocket as well?

03-06-2009, 10:41 AMNo. I would have preferred to do so rather than the wheel sprocket but I came across some problems of space and availability of alternative sprockets.
See this thread for an explanation:

03-06-2009, 04:46 PMHi forch, i been reading some post elsewhere and according to them the fron sprocket of the Suzuki SX125 is compatible with the QM200 (The name in Chile for que QM200 is Euromot GXT200). Its a 16T sprocket and the only detail is that it is a little wider in the middle but is easily solved.
The 2 first links are for the post I was telling you about (in Spanish) and the 3rd one is the detail of the sprocket they mention it

03-07-2009, 01:20 PMRight, this is for the Sherlock Holmes amongst you. Here are some pics of the rear sprocket belonging to my Pioneer GY200. The number stamped on the back is 428-51T, pretty obviously a 428 pitch chain with a 51 tooth sprocket!
The hub houses four rubber bushes. Four studs of 8+mm diameter are secured to the sprocket with nuts and ample amounts of locktite. The sprocket just plugs into the bushes and is held in place by one large circlip.
Can anyone identify with this type? The rubber bushing no doubts cushions any shock treatment transmitted through the drive chain, synonymous with a Suzuki design. I want to source a smaller sprocket for reasons already explained on this post.

03-07-2009, 03:05 PMJust a few more details to add on the rear sprocket: the four holes are on a 90mm diameter, 64mm between centers and take what appears to be an 8,2mm stud. I have scanned the drawngs in the 125cc Suzuki section of JT Sprockets with no luck. I'll keep looking.......
Any suggestions would be gratefully received. Cheers!

03-07-2009, 09:10 PMThanks for the photos.
Another mystery to solve in the never-ending quest to understand the thinking of Chinese makers...
Curiously enough one of our posters, LuisCarlos, from Brazil, is looking for a cush drive rear sprocket hub to stop the possibility of the bolt breakages we've been hearing so much about.
This is the thread: http://www.mychinamoto.com/forums/showthread.php?t=510
The hub on your bike seems a superior arrangement to the one our Qingqi comes with and I'll bet it's interchangeable with ours. A rubber-cushioned cush drive like yours should feel a lot smoother and be easier on the transmission. On top of that the fixing of the sprocket will not shear as easily as just bolts.Jincheng Monkey JC50Q-7

03-07-2009, 11:49 PMHave a look at these drawings taken from JT Sprockets. I had a look for components with a 4 hole 90 mm pitch circle diameter like yours and it appears that several versions of the Honda CB125, CB175, and CG125 use that.
The only data missing from yours is the diameter of the centre hole. All these are 58 mm, is yours the same?.
Notice that these sprockets have two sets of holes, four with 8.2 mm diameter and 4 with 10.5 mm.
Honda CB125
Honda CB175
Honda CG125E
Honda CG125 Brazil
It looks like the closest could be the CB125. Take a look at how similar the rear wheel assembly of it is. Note the rubber cush drive bushes, four hole sprocket, large circlip fixing etc, on this drawing:
