What is a Class 3 or 4 road?
Sorry for the confusion on the road classification numbers. Since I am from Texas and have been on a lot of Texas specific duel sport web sites lately I threw the numbers out like everyone across the country would know what I was talking about. In fact, the rating system that I was refering to was created by Richard Gibbens who is the arthor of some duel sport ride guides for the Texas Hill Country and Big Bend area. He also has a web site and holds several rides each year. The discription is below.
Class 1: Improved dirt, gravel, etc. Passable by any motorcycle capable of off-pavement travel.
Class 2: Poorly maintained dirt, gravel, etc. Rocks, sand, mud holes, ruts, inclines, water crossings, or other similar obstacles make this road difficult for larger, heavier adventure motorcycles and requires some rough terrain riding skills.
Class 3: Rugged, unmaintained dirt, gravel, etc. roads. Significant obstacles such as moderate sized rocks, deep sand, deep or long mud sections, deep & wide water crossings, and/or steep inclines with loose terrain & tentative traction make this road/trail extremely difficult for large adventure bikes and very challenging for large dual sport motorcycles such as 650cc thumpers. Advanced rough terrain / off-road riding skills advised
Class 4: Extremely rugged road that contains highly challenging obstacles such as steep drop-offs, deep & fast moving water crossings, very steep inclines with loose surface, boulders, deep & long mud sections, downed trees, and deep & long sand sections. Generally not passable by large adventure bikes, extremely difficult for large dual sport motorcycles such as 650cc thumpers, and very challenging for smaller dual sport / trail bikes. Should be attempted only by those with significant rough terrain / off-road riding skills and experience.
