I'm not worried about the counter shaft (C/S) sprocket. The C/S sprocket appears to be a readily available, Suzuki sprocket.

However, I suspect the RX3 employs the same cushion hub as my Zongshen ZS200GY-2. If so, this hub utilizes a Kawasaki, or Zongshen rear sprocket, which might not be available in larger sizes suitable to maintain the stock gear ratio for the larger rear wheel. The 17-inch rear wheel of the Minsk TRX 300i employs a different hub.

However, I would not be content merely to maintain the stock sprocket ratio. I would like the ability to experiment with different sprocket ratios for different riding conditions. If the cushion hub doesn't have a nice variety of larger sprockets available, I would prefer the 17-inch, rear wheel employed by the Minsk TRX 300i. The hub on this wheel appears to employ either Honda, or KTM rear sprockets, which are available in a wide variety of sizes.
