Is it true that the Mojave ATV shares the same engine/tranny? Yes and no. The KLR and Mojave have very similar engines but there are distinct differences. The most obvious is the transmission, while the KLR has a six speed tranny, the Mojave has a five speed with reverse. The heads of the engines are basically identical but the parts used in each vary from year to year. Check out the camshaft part numbers below and you'll see what I mean. Not only did Kawasaki use different cams in the KLR through the years but the Mojave had its own specific cams as well.
