The 2006 Honda CRF70F is Honda's youth trail bike, the step between the CRF50F and the bigger CRF-F models. It has a carbureted, air-cooled 72cc single with a SOHC two-valve head and a 13 mm carburetor, a kickstarter, and a three-speed gearbox with an automatic clutch, so there is no clutch lever. It has a 27 mm fork, a single rear shock and drum brakes front and rear, on 14-inch front and 12-inch rear spoked wheels. It belongs to the generation Honda introduced for 2004, which ran through 2012 before the CRF110F replaced it. It came in red.
Who it's for
Young riders moving up from a smaller bike such as the CRF50F who aren't ready for a clutch lever: the automatic clutch and low 26.1-inch seat let them learn to shift at their own pace. It starts with a kickstarter only. Honda's weight limit is 132 lb, rider and gear included. It is for off-road use only, carries one rider, and has no lights.

JT lists 86 links for this bike (count yours to be sure); stores sell this chain at 90. Cut it to length with a chain breaker (any shop can do it): spare links are normal. D.I.D D: a standard 420 chain (D.I.D makes no sealed chain this small). If your manual names a heavy-duty chain (420DS3), that fits the same and lasts longer.
