I have verified the EBC, MD929D brake rotor is a perfect fit for the front wheel of the Zongshen RX3. This brake rotor fits the following motorcycles.
Front Wheel
98-02, Suzuki Burgman 250
99-02, Suzuki Burgman 400
I bought an Arashi, DBS016W brake rotor for my RX3. This brake rotor has eliminated my previous problems with a pulsing front brake. The Arashi brake rotor is very well manufactured, and is definitely superior to the stock, PSM brake rotor.
Here are several photographs of the Arashi brake rotor mounted on the front wheel of my Zongshen RX3.
