The short answer
These are the same motorcycle. KTM, Husqvarna and GasGas are all badges of one company — KTM AG, renamed Bajaj Mobility AG in January 2026 after India's Bajaj Auto took 74.9% of it — and the SX-E 5, EE 5 and MC-E 5 share a battery, a motor, suspension travel, wheel sizes, ride modes and a charger. We read all three 2027 US model pages side by side and found one functional difference between them.
- GasGas MC-E 5 — $5,449, Score 87. The one to buy. Same bike, least money.
- KTM SX-E 5 — $5,799, Score 86. $350 more for orange plastics and the deepest dealer network of the three.
- Husqvarna EE 5 — $5,849, Score 86. $400 more, and the only one that publishes a way down to a 24.2 in seat — the single reason to pay it.
All three carry the same $425 freight, so the delivered spread is $5,874 / $6,224 / $6,274.
That is the whole decision. The rest of this page is the evidence, because "they're the same bike" is the kind of claim that deserves to be shown rather than asserted.
One thing this page deliberately does not cover: whether the company behind all three badges is a safe bet. KTM AG went through Austrian insolvency in 2024, wrote off roughly 70% of what it owed creditors, and was taken over by Bajaj. On a $6,000 machine you are buying dealer support, parts and warranty for years, so that history is part of the purchase — we lay it out in full in does KTM make an electric dirt bike?, which also covers the adult Freeride E and the smaller SX-E 2 / MC-E 2 pair.
What is genuinely identical
Every figure below is published on all three manufacturers' own 2027 US model pages, and matches across all three:
| KTM SX-E 5 | Husqvarna EE 5 | GasGas MC-E 5 | |
|---|---|---|---|
| Battery | 907 Wh | 907 Wh | 907 Wh |
| Peak power | 5 kW @ 3,900 rpm | 5 kW @ 3,900 rpm | 5 kW @ 3,900 rpm |
| Front travel | 205 mm (WP XACT) | 205 mm (WP XACT) | 205 mm (WP XACT) |
| Rear travel | 193 mm (WP XACT) | 193 mm (WP XACT) | 193 mm (WP XACT) |
| Wheels | 12 in / 10 in | 12 in / 10 in | 12 in / 10 in |
| Ride modes | 6 | 6 | 6 |
| Charge, 80% | 45 min | 45 min | 45 min |
| Charge, 100% | 70 min | 70 min | 70 min |
| Weight | not published | 40.5 kg (89 lb) | 40.5 kg (89 lb) |
| Freight | +$425 freight | +$425 freight | +$425 freight |
| Price | $5,799 | $5,849 | $5,449 |
On the weight row, note what we did not do. KTM does not publish a weight for the SX-E 5. We carry 89 lb for it, taken from the identical Husqvarna and GasGas platform figure and labelled in our catalog as borrowed, not presented as a KTM number. It is almost certainly right. It is still not KTM's figure, and you should know which of the numbers you are reading came from where.
The one real difference: how low the seat goes
This is where the three stop being interchangeable, and it is the spec that decides a kids' bike.
| published seat height | |
|---|---|
| KTM SX-E 5 | 24.9-26.8 in (634-682 mm), adjustable |
| GasGas MC-E 5 | 24.9-26.8 in (634-682 mm), adjustable |
| Husqvarna EE 5 | 26.1 in standard, 24.2 in (615 mm) after two adjustments, 21.6 in (550 mm) with the optional Suspension Lowering Kit |
The Husqvarna's lowest published setting, 615 mm, is 19 mm below the 634 mm floor KTM and GasGas publish — about three quarters of an inch. On an adult bike that is noise. On a bike for a rider who needs to touch the ground to feel brave, it is the difference between a good first season and a bad one.
We have had this backwards before, and said so. Until 2026-07-27 our KTM brand guide compared the KTM/GasGas minimum against the Husqvarna's standard setting and concluded the Husqvarna sat higher. It does not; it reaches lower at every setting you can get to without accessories. We corrected it in public rather than quietly, and the same trap is why our catalog still stores one number for a bike with a range (`CR-014`).
Two further caveats. First, these are published figures, not our own measurements — the three brands describe their adjustment differently, and we have not put a tape on all three. Second, the Husqvarna's 21.6 in figure needs an accessory you have to buy separately; do not budget as though it is included.
If your child is comfortably inside the size range, this difference should not cost you $400. If they are at the bottom of it, it is the only thing on this page worth paying for.
Why the cheapest one scores highest
The VoltRipper Score puts the GasGas at 87 and the other two at 86. Read that carefully, because it is easy to read backwards.
It is not saying the GasGas is the better machine. It is the same machine. When every performance input — power, battery, travel, wheels, modes, charge time, weight — is identical across three bikes, the only variable the Score has left to move on is money. A one-point gap on a $350-$400 price difference is the model working exactly as designed and saying something very narrow: of three identical bikes, buy the cheap one.
This is a useful thing to understand about the Score generally. It rewards fitness for purpose and value, so when it separates bikes that share a platform, it is almost always separating them on price. Where it gets interesting is between genuinely different machines — and this trio is the clearest example on our board of a Score gap that carries no engineering meaning at all.
Should a kid have a 5 kW race bike?
The honest answer for most families is no, and the price list is not what should decide it.
These are competition machines sold through motorcycle dealers: 5 kW, 205/193 mm of WP suspension, six ride modes, a 45-minute fast charge. They exist because junior moto classes exist. A child who lines up on a gate needs this bike, and $5,449 is a fair price for it.
A child who rides the back paddock on Saturdays does not. The Greenger CRF-E2 at $1,799 — Score 83 — is the same shape of bike for a third of the money: 2.5 kW, a 20 mph top speed, 100/97 mm of travel and two modes. It is slower and softer, which for recreational riding is the point. It also publishes a 12-month warranty, which none of the SX-E 5 trio does on its US model page.
The test is a race calendar, not a birthday. If one exists, buy the platform on this page and buy the cheapest badge of it. If one does not, the trio is a great deal on capability nobody in your house is going to use.
Where this leaves you
- Racing, normal-sized rider → GasGas MC-E 5, $5,449. Identical bike, least money, highest Score of the three for exactly that reason.
- Racing, small rider → Husqvarna EE 5, $5,849. The 24.2 in setting is real, and it is the only functional advantage anyone is selling you here.
- Racing, and your dealer is the reason → KTM SX-E 5, $5,799. Parts and service proximity is a legitimate reason to pay $350. "It's a KTM" is not.
- Not racing → Greenger CRF-E2, $1,799. Buy the riding your child will actually do.
Not sure which size band your rider is in? The Find Your Ride configurator takes rider height and weight and returns fitted picks across the whole youth class, not just these four.
A note on what we make from this page: nothing. None of these four bikes has an affiliate program we can join — they are sold through franchised motorcycle dealers, not the retailers that pay commissions. We wrote it anyway, and we are telling you to buy the cheapest one on the list, which is the recommendation we would make either way.
FAQ
Are the KTM SX-E 5, Husqvarna EE 5 and GasGas MC-E 5 the same bike?
Mechanically, near enough that the differences do not change how the bike rides. All three are built by the same company — KTM AG, now 74.9% owned by India's Bajaj Auto and renamed Bajaj Mobility AG in January 2026 — and share the same 907 Wh battery, the same 5 kW peak motor at 3,900 rpm, the same WP XACT suspension with 205 mm front and 193 mm rear travel, the same 12-inch front and 10-inch rear wheels, the same six ride modes, and the same 45-minute 80% charge. We found one functional difference across the three published spec sheets: the Husqvarna EE 5 reaches a lower seat. KTM and GasGas publish an adjustable 24.9-26.8 in; Husqvarna publishes 26.1 in as standard, dropping to 24.2 in with two adjustments, and 21.6 in with an optional lowering kit. Everything else that differs is graphics, plastics and price.
Which of the three should I actually buy?
The GasGas MC-E 5 at $5,449, unless you need the lowest seat or you have a reason to prefer a particular dealer. It is $350 under the KTM SX-E 5 ($5,799) and $400 under the Husqvarna EE 5 ($5,849) for the same platform, and all three carry the same $425 freight. Buy the Husqvarna instead if your child is at the bottom of the size range — it is the only one of the three that publishes a way down to 24.2 in without accessories, and 21.6 in with them. Buy the KTM if your nearest or best-stocked dealer is a KTM dealer, which is a real advantage on a race bike that will need parts, but not one worth inventing if it does not apply to you.
Why does the cheapest of the three score highest?
Because when three bikes are mechanically identical, price is the only input left for the VoltRipper Score to separate them on. The GasGas scores 87 and the KTM and Husqvarna both score 86 — a one-point spread that is entirely the $350-$400 price difference, not a judgement that the GasGas is a better machine. It is the same machine. This is a case where the Score is doing something narrow and doing it honestly, and where you should read the number as the cheapest badge on a shared platform rather than as a verdict on engineering.
Is a $5,449 electric bike worth it for a kid, or should I buy something cheaper?
It depends entirely on whether your child races. These are race bikes: 5 kW, 205/193 mm of WP travel, six ride modes and a 45-minute fast charge, sold through motorcycle dealers to families running a moto program. If your child rides in the yard or on trails a few weekends a month, they are far more bike than the job needs. The Greenger CRF-E2 at $1,799 covers recreational riding with 2.5 kW, a 20 mph top speed and 100/97 mm of travel — a third of the money for the riding most kids actually do. Buy the SX-E 5 class when there is a race calendar; buy the Greenger when there is a backyard.
What does the SX-E 5 platform cost delivered?
Add $425 freight to every one of them — that is the same figure on all three manufacturer pages, and it is not optional. So the GasGas MC-E 5 is $5,874 delivered. The KTM SX-E 5 is $6,224 delivered. The Husqvarna EE 5 is $6,274 delivered. All three figures are before dealer setup, tax and any state fees. None of the three publishes a warranty term on its US model page, which is worth asking your dealer about in writing before you sign anything.
