Came across this article on the RX3 while googling info on what bigger rims and tires might fit. Interesting that all the arguments I've been making for years concerning what makes a good adventure bike and rider, such as skinny, tall front tires, 11 inches of suspension travel, and Chinese leather skinned 2x4 seats don't suit adventuring, backed up right here.
Whatever you do, DO NOT follow your motocross and desert race experiences when modifying an RX3--you will only ruin it. If you want to learn about adventure bikes, you'll learn a lot more, a lot quicker, and a lot less painfully, by listening to the few of us that have actually ridden 10s of thousands of miles of dirt roads. While what can be learned racing does have significant value, especially in emergency situations, adventure routes are not race tracks and the standard procedures for successful adventure
riding are very different than any kind of racing.
Rest assured that your RX3, while not perfect, is the best all around Adventure bike in the world for individuals who actually do adventure rides without a crash crew to pick up the pieces, make and break camp, do the dishes, and summon helicopter ambulances when necessary.
