rizwan motors usually has lots of yammy rx parts.. the rest you can figure out yourself like circlips, bearings, seals etc, small body parts were also shared in the YB100 royale too - so thats easy.
the machine is very simply built and is very easy to service too.
for bearings dont buy from the parts shop, go to the SKF dealer behind plaza and get SKF bearings for it - if its for the engine then make sure to remove the seals and wash out the grease from it - grease will mess up your engine very badly. If its for wheel hubs, do the job correct and knock out one seal and repack with high quality chassis grease in the hub..
as I said - its a very simply built small motorcycle.
