2002 wr426f Used every day,mostly to work & back, about 25km. When we can,we go off-road ,up the mountain. But the bike has never been to the track or raced. When i brought the bike it was in super new condition,with 3000km on the clock.Now its 11000km ,mostly road work. I change the oil every 1000km ,give it a good thrashing,and look after it well. The Cam Chain has never been changed, the engine never opened. I think the bike has had a very easy life. What do you think ?
