I believe the bike I have is manufactured by the same company, if not someone copied someone. I have a MSX200GY-7 Motorstar here in the Philippines and have been looking to get a bigger sprocket for on the rear for better off road rides. I talked to the sales person and mechanic at the place I bought it and the mechanic called another store and they told him a certain Honda sprocket would fit it so he is suppose to try and match it up . The sprocket in your post on this looks just like mine so I am going to let them look at this post of yours before destroying anything to make it work. I would like to go 52T at least
