GasGas MC-E 5 vs KTM SX-E 5: Which Kids MX Bike Wins?
The GasGas MC-E 5 and the KTM SX-E 5 are the two serious youth electric motocross bikes for riders roughly aged 4–12, and they come from the same Austrian group. They share the core 5 kW water-cooled platform, the frame generation and, typically, the price. So what actually separates them?
Here is the honest comparison for a parent choosing between them. Both are in the youth & kids category.
What they share
Both bikes use the same 5 kW water-cooled motor, the same 2025-generation frame, adjustable seat height and selectable ride modes, and both suit riders roughly 4–12 who are already confident on a smaller machine. On the track, a rider would be hard-pressed to tell them apart blindfolded.
Pricing is essentially identical — both land around $5,449 as an estimate, subject to import tariff conditions. These are genuine competition-capable youth MX bikes, not toys, and both are off-road use only.
What actually differs
The meaningful differences are bodywork, graphics and colour. KTM runs its familiar orange; GasGas runs red with its own plastics profile. Some riders and families have a strong brand preference — a young racer who idolises a particular factory rider will care which badge is on the tank.
Dealer support and parts availability can vary by region, so in practice the tie-breaker is often which brand your local track and riding community leans toward, and which one we can get to you fastest.
How to choose
Buy whichever has better availability when you order, whichever your rider prefers the look of, and whichever fits your local support network best. There is no performance reason to pick one over the other.
If your rider is younger or newer, the smaller KTM SX-E 3 or GasGas MC-E 2 may be the better fit — going up a size too early makes a bike harder to learn on. Our best electric dirt bikes for kids guide covers sizing by age.
Where these sit against STACYC and Razor
The MC-E 5 and SX-E 5 are a big step up in price and capability from a STACYC balance bike or a Razor Dirt Rocket. They are for kids who are already riding confidently and want to race or ride a real MX track.
A child still learning balance and throttle control is better served — and safer — on a STACYC or an entry Razor first, then moving up to one of these when the skills are there.
