Now that these bikes have been around for nearly 2 years just curious to know how they are holding up? Anyone had an engine let go? My bike is serving me well. I have 150hr on it (6,500km) and the bike has not missed a beat. I have 2 sets of wheels and swap them over. I ride it to work everyday (20km) and on the weekends put the rims with dirt tyres on them. I change the oil every 1000km, wash the filter skin every bush ride and the filter when it looks dirty. Have a stainless oil filter that I wash every service and the I checked the vavles once and they were in spec. Best thing I bought was an IMS 3.1 gallon tank. Can ride all week to work now without filling and do longer bush rides. And I also have another back rim that has a paddle tyre and hit the dunes for some more fun! I actually sold 3 bikes when I bought this bike. A road bike, CR500 dune bike and my last WR250F. This bike does it all!!
