A six-and-older model, not a small Raptor 110
Yamaha’s US YFZ50 listing identifies ages 6 and up and states that this configuration is not available in California. Its resemblance to a larger sport ATV does not transfer that larger model’s operator category. Confirm the intended market and the actual unit’s labels before purchase.
The controls and the delivery budget
Yamaha identifies an automatic CVT, electric start with backup kickstart, an adjustable limiter and a power cut-off tether. Examine the tether and limiter under the owner instructions before running the engine. The backup starter is not a reason to disregard an electrical fault, and a limiter does not make an unsuitable control reach acceptable.
At the posted $2,499 MSRP plus $350 destination, the two advertised price lines total $2,849. Dealer preparation, taxes, title and other applicable fees can add to that amount. Ask for those charges separately, so a discounted selling price and an added preparation fee can be compared with another quote.
Yamaha’s 2027 specification labels 220 lb as wet weight with standard equipment, operating fluids and a full tank; accessories remain additional. The 49.2-inch length and 32.3-inch width describe the machine’s footprint. Tie-down clearance and ramp suitability require measurements beyond that rectangle.

What it costs to put on the ground
A helmet, gloves, eye protection, boots and chest protector are additional and matter more than the machine for a young child.

Who it suits
