When I was restoring an old Chunlan Starway scooter,
I discovered that one part I needed was a front brake light switch. It seemed unlikely that I would find a Chunlan dealer, so I sought an alternative. Knowing that all Chinese bikes are copies of Hondas I went to my local Honda dealer. He let slip a very interesting piece of information....there are only about 4 or 5 different types of brake lever used by Japanese bike companies, and they are bought in by the bike companies. For each lever there is a specific switch. My chunlan was a Honda copy so sure enough there was a switch available.
At the same time I had a Honda SH50 which i was taking to pieces in my back garden. I looked at the front brake caliper. It was identical to the Chunlan and to the SYM moped I was working on at the time.
My point is this...The Chinese companies who make our favourite bikes are not in the business of re-inventing the wheel. It is likely that the parts they use are copies of existing parts from the Honda SYM and KYMCO ranges. The parts you need are out there. Go and look.
Cool! Anyone else noticed interchangeable parts? BTW, another part I've noticed is that the Italjet Dragster rear light unit is identical to the the one from the Yamaha Aerox. I have bought both types from eBay and Scooters-r-us. Im certain of this. There are 2 types. Lights meant for a 125cc have a clear bottom panel which illuminates the number plate. On a light for a 50, which needs no numberplate light, the panel fitted is in red plastic. This can be replaced with ordinary perspex if you want to fit the light to a larger/derestricted bike.
