New and used small motorcycles are available for purchase across the United States at Honda dealerships and online at CycleTrader.com, Oodle.com and eBay.com, as of 2015. Most of the motorcycles have 40- to 110-cubic-centimeter engines.
The listings on Cycle Trader include small motorcycles from Suzuki, KTM, Taotao, Yamaha and Honda. Some of the small bikes are dirt bikes, and others are sport bikes. Users can refine the listings by year, mileage and whether or not the bike is used.
EBay's selection includes many small motorcycles with a dirt bike frame, and those models' engines are around 50 cubic centimeters. Honda markets its Grom model as having real motorcycle features and a 125-cubic-centimeter engine. Shoppers can buy the Grom new from local Honda dealers.
