The Apollo RFZ Z40 140cc Adult Dirt Bike is a large-frame off-road motorcycle built for trail riding, practice tracks, and aggressive recreational riding.

Featuring a 4-speed manual transmission with clutch (N-1-2-3-4) and a rugged chain drive system, the Z40 gives riders full control over gearing and acceleration. The bike is equipped with front and rear hydraulic disc brakes, long-travel suspension, and a double-beam heavy-duty steel frame designed to handle jumps, rough terrain, and hard riding.
With a tall 32.5-inch seat height, high 14.5-inch ground clearance, and a 17/14 wheel setup, the Apollo Z40 is ideal for teen and adult riders looking for a capable mid-size dirt bike with professional-style handling.

Rated 4.6 / 5 by 151 buyers
Bought this for my 9-year-old and he's obsessed. The adjustable speed limiter let me start him slow then open it up as he got confident. Arrived crated and well-packed.
Was nervous ordering a $1,200 ATV online but their phone support walked me through everything. Shipping was free and showed up in 5 days. Runs great.
