Kawasaki KX100

The KX100 is a 2-stroke motorcycle made by Kawasaki. The bike offers a good transition between the traditional 85cc bikes and the 125cc bikes by having larger wheels (19 inch front, 16 inch rear, compared to 17/14 of normal 85's). Its predecessor is the KX80 Bigwheel, which is still sold in the UK under the name "KX85 II". Longer travel suspension and larger bore size main differences between these bikes which otherwise are the same.

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. The KX100 can sometimes be raced in the 125cc class however, 100cc bikes are not very common.
