Adventure bikes are long-travel bikes designed for going as fast as possible downhill on the hardest trails around. Their geometry is built for speed on the descents, but also for crawling back uphill to start the next race stage and also fantastic road bikes. Many riders actually buy Adventure bikes for the comfy riding position, great protection from the elements and indeed smooth suspension on the road. Adventure bikes tend to be taller than the other types of motorcycles and typically have larger engines.
