The Kawasaki KX100 is a 2-stroke motorcycle manufactured by Kawasaki. The KX100 can be raced in dedicated 100cc motocross classes, or open minicycle classes (such as Supermini in Canada, which allows up to 150cc 4-strokes and 85cc-112cc 2-strokes as of 2007). Sometimes the KX100 is raced in the 125cc class because 100cc bikes are not very common, and a particular sanctioning body doesn't create a class for them. Its predecessor was the KX80 bigwheel, which is still sold in the UK under the name "KX85 II". The bike offered a good transition between the traditional 85cc bikes to the 125cc bikes by having larger wheels (19 inch front, 16 inch rear, compared to 17/14 of normal 85's). Longer travel suspension was added but otherwise the bikes are the same.
