Zongshen 200GY-2 Gets A Yamaha XT225 Swingarm Conversion
About a week ago my good friend Andy helped me to complete a Yamaha XT225 swingarm conversion on my 2006 Zongshen Sierra 200GY-2 motorcycle. This conversion allows me to use 18-inch rear tires on my Zong. The alloy rear rim and smaller hub lighten the bike considerably. Also, my Zong now handles much better, and the adjustable Yamaha XT225 shock absorber has greatly improved the bike’s suspension! This conversion did not cost much, and I am very pleased with the results.

Inside the yellow circle you can see the shock mounting bracket fabricated, and welded to the Zong’s frame by my good friend Andy. ![]() ![]() Finally, here is a photograph of the left underside of the shock mounting bracket, showing the Yamaha lower shock linkage, and grease zerks. ![]() Spud ![]()

Very Nice Spud!
I knew you couldn't resist doing more mods...haha How did you fab up that shock mount? Were you able to get one from a XT or was that from scratch? I am still waiting for the exhaust, otherwise has been too much rain for any riding. |

with all the talk of the bikes having "poor" suspension, this is definitely the best way of fixing it! great job and nice pictures

The biggest problem solved with this is tire replacement.
Plenty of tire options now. Spud. Do you feel that you need to change anything on the front now or do it feel right with the stock front wheel? Allen

AWESOME!
Good friend you have there, Spud! How's it handle now that the front well is proportionatly smaller? Did it quicken the steering with a lower nose attitude? Hurt 'high' speed stability?

![]() ![]() We also had a Yamaha TT-R225 motorcycle nearby to examine for the proper location and angle at which to weld the shock mount to the Zong’s frame. ![]() We lifted the Zong with my Home Depot jack, and removed the rear wheel and swingarm. You can see the Zong's 15-inch rear wheel leaning against the shop door. ![]() ![]() Then we mounted the Yamaha XT225 shock absorber and swingarm to the Zong’s frame. ![]() After comparing the shock absorber action of the Yamaha TT-R225 motorcycle at various degrees of weight load, Andy welded the shock mount to the Zong’s frame. He then ground down the angled lower edge of the shock mount before welding on a ¼-inch by 1-inch steel plate to reinforce the mount's attachment to the bike's frame. ![]() ![]() Here is the shock mount in it’s final position, before it was painted black. ![]() Spud ![]()

![]() ![]() In answer to your questions, the bike handles great, much better than before! Indeed, the steering did quicken, and it feels wonderful! This conversion did not hurt the motorcycle's stability at any speed. The Zong is now much lighter, and it both feels and handles as a much lighter motorcycle! Also, the bike's suspension has improved dramatically! I could not be happier with the results obtained from this conversion. ![]() Essentially, I now own a Yamaha motorcycle. The Zong's airbox, carburetor and engine are faithful copies of the same parts in a Yamaha TW200 motorcycle. Therefore, the Zong's exhaust header and muffler can also be replaced with Yamaha OEM or replacement parts. ![]() ![]() Spud ![]()

Your bike has the exact same exhaust as my ZUKI....Wonder if a dr swingarm would be a direct fit......Maybe I should not say that now
