Choosing between two gas dirt bikes that look almost identical on a spec sheet can feel harder than deciding between two completely different models. Both of these MPR Bikes options are 40cc 4-stroke machines aimed at kids and adults, and both carry the same suspension system, centrifugal automatic transmission, easy pull starter, and cross-drilled disc brakes. These compact gas bikes pair a 40cc engine with an automatic transmission, which suits the kids-and-adults audience named in both titles. With the listed prices only $10 apart, the practical difference narrows to color, model naming, and how much that $10 matters to you.
Quick Verdict
For riders who want the lowest listed price, the Green Motocross at $339 is the more direct pick. For anyone who prefers the orange finish and the Moto X race-bike branding, the Orange Moto X at $349 delivers the same core package for an extra $10 on the listing. Neither bike offers a meaningful mechanical advantage over the other, so the verdict depends on color preference and the price spread.
| Product | Listed Price | Price Bar | Key Attributes |
|---|---|---|---|
| Gas Dirt Bikes for Kids \& Adults | Moto X (Orange) | USD 349.00 | 40cc 4-Stroke, Full Suspension System, Orange | |
| Dirt Bike Motocross Moto X Gas Motorcycle (Green) | USD 339.00 | 40cc 4-Stroke, Full Suspension System, Green |
Where Each Product Wins
Orange Moto X wins on: the race-bike presentation in its title and the orange colorway, positioning it as the more track-styled pick of the two. If the color and styling matter more than the price gap, this is the one.
Green Motocross wins on: the $10 lower listed price and the green colorway. It also puts the 25+ MPH figure directly in its title, which makes the speed claim visible at a glance.
Product Notes
Gas Dirt Bikes for Kids \& Adults - Moto X (Orange)

This is the $349 MPR Bikes entry with an orange colorway and the Moto X race-bike title. It shares the same mechanical package as the green version, so the ride characteristics are identical. The bike's title leads with the 4-stroke off-road positioning, which reinforces the intended use on trails and dirt. For families comparing gas-powered options, the Moto X name gives this version a slightly racier identity even though the spec list matches. Choose it if the orange finish and the off-road race-bike presentation are worth the $10 price gap. The limitation is simply that you pay the higher of the two listed prices for essentially the same machine.
Dirt Bike Motocross Moto X Gas Motorcycle (Green)

This green MPR Bikes model lists at $339, making it the lower-priced of the two. It carries the same mechanical package as the orange Moto X, so nothing is lost in terms of the engine or suspension. The title emphasizes the 25+ MPH figure, giving this version a clear speed-oriented identity. For those shopping for a kids-and-adults trail bike, the green colorway stands out from the usual red or orange machines. Its limitation is cosmetic rather than functional: if green is not your preferred color, the $10 saved may not matter enough to change your mind.
Final Choice by Use Case
Choose the Orange Moto X when you want the race-bike styling cues and the orange colorway, and you are comfortable with the higher of the two listed prices.
Choose the Green Motocross when you want the lower listed price and a green finish, and you are happy with the same shared platform underneath. If you are choosing for a young rider, the automatic transmission on both models removes clutch work, but color preference often decides the argument.
