Zongshen RX3: 21-inch Front Wheel

[SpudRider]

Several days ago I laced a Warp9, size 1.60-21 rim to the front hub of my Zongshen RX3, and mounted a size 2.75-21, Cheng Shin, C858 tire to the front wheel.



Prior to lacing the 21-inch rim, I had raised the front fender, and road tested the configuration to ensure I had adequate clearance between the front fender and the rest of the bike.

















I raised the front of the fender a distance of 1-9/16" by mounting the metal frame of the fender to the top point of the front mounting bracket. I added a short section of aluminum bar stock to raise the rear of the fender the same distance. I also trimmed the inside edges of the fender near the forks to allow the forks to descend without rubbing the fender. I discovered I also need to trim a little from the rear of the fender, because it contacts the exhaust header when the forks are fully compressed. Otherwise, the fender is very solid, and doesn't contact the rest of the motorcycle.
