XE Pro S Enduro

The verdict

The Arctic Leopard XE Pro S Enduro is the cheaper half of Arctic Leopard's confusing two-bike XE Pro range, and on the numbers it is the more interesting one. For $5,100 you get 20 kW peak (27 hp), 600 N·m, a 3,960 Wh removable pack, 21/18 enduro wheels, 220 mm four-piston hydraulic brakes at both ends, and a direct-drive powertrain with no belt and no jackshaft to wear out. It earns a VoltRipper Score of 92/100.

That puts it a couple of points above its own bigger sibling, the XE Pro R (91), which makes roughly one-third more power for a higher price. Our Score weights capability per dollar, and at this price the S takes back on value what it gives up on output.

The reason to be careful is not the bike. It is the paperwork around it.

Who it's for — and who should skip it

Buy it if you want full-size 21/18 enduro hardware under $5,500, you like the idea of direct drive with nothing to service between motor and wheel, and you are comfortable being more self-reliant on parts and support than a Sur-Ron owner would be.

Skip it if you want a proven platform with a decade of aftermarket behind it, you need published warranty terms before you spend $5,000, or you are a newer rider — 20 kW and a claimed 63 mph is a lot of bike, and it is expert-rated for a reason.

Two things the dealers keep getting wrong

This is the part of the review that matters most, and it is the reason we score the manufacturer's figures rather than a dealer's.

1. The battery. Arctic Leopard says 72V 55Ah — 3,960 Wh. At least one major US dealer lists this bike with 74V 60Ah — 4,440 Wh, which is the XE Pro R's pack, line for line. That is not a 480 Wh difference in the wild; it is a spec sheet copied from the wrong variant. A second dealer prints the correct pack but gives a lower weight with a kilogram conversion that does not close. Get the pack size in writing before you pay.

2. There are two XE Pro S variants and they are not the same bike.

Dealers routinely list both under one product page with one price. Wheel size is the reliable tell — if the listing says 19/16, you are looking at the supermoto Super, not the enduro reviewed here.

What you actually get for $5,100

The headline is the drivetrain. Direct drive means no belt and no jackshaft — two of the most common service items on a Sur-Ron or Talaria simply do not exist here. For a rider who would rather ride than maintain, that is worth more than a spec-sheet line suggests.

The rest is straightforwardly good for the money: 21/18 wheels put it in the full-size enduro class rather than the light-e-moto one, the KKE suspension is adjustable at both ends, and 220 mm four-piston brakes are real hardware rather than the single-piston units common a tier down. At 165 lb it is light for what it is — an Ultra Bee is 195 lb and a Talaria Komodo 216 lb.

The number to be honest about: range

Arctic Leopard claims 50 miles. Dealer listings advertise "up to 100 miles at 20 mph."

The second figure is not a lie, but it is not range either — it is what the bike will do at a constant 20 mph in eco mode, which is not how anyone rides an enduro. We score the 50-mile claim and leave our real-world figure blank, because no instrumented run has been published for this bike and we do not invent one.

For context: across the bikes where we hold both a claimed and a measured figure, real range averages about 59% of the claim. Applied here, that means you should expect materially less than the claim ridden hard — but that is an inference from the class, not a measurement of this bike, and we are labelling it as such.

XE Pro S vs XE Pro R — which Arctic Leopard?

The R is more bike in every direction that costs money. The S is $599 cheaper, 10 lb lighter, and gives up 6.5 kW — and for most riders that trade lands in the S's favour, which is why it edges the R on our board despite the smaller spec sheet.

Take the R if you will genuinely use its extra peak output. Take the S if you want the same chassis and most of the capability for less. (Full XE Pro R review →)

Where it sits against the establishment

Against a Sur-Ron Ultra Bee ($6,499, Score 94), the XE Pro S is $1,399 cheaper, 30 lb lighter, runs bigger wheels, and claims more speed. What the Sur-Ron answers with is not on the spec sheet: a decade-deep aftermarket, the widest dealer network in the class, and resale that actually holds. That is a real answer, and for a lot of buyers it is the right one — but it is a support argument, not a hardware one, and it should be priced honestly rather than assumed.

Against a Talaria Komodo ($5,999, Score 91), the S is cheaper and 51 lb lighter, and gives up meaningful peak power.

Bottom line

The Arctic Leopard XE Pro S Enduro is a lot of enduro for $5,100 and its 91 reflects genuinely strong capability per dollar. The hardware is not the risk. The risk is a young brand with unpublished warranty terms, a thin support network, and dealers who cannot reliably say which battery is in the bike or which of two variants they are selling.

Buy it with the pack size and the wheel size confirmed in writing, and it is a strong buy. Buy it off a listing without checking, and you may receive a different bike than the one you read about.

VoltRipper is spec-verified and data-driven — we do not claim hands-on testing of this bike. Specs and prices are cross-checked against the sources listed on this page, and where a manufacturer and a dealer disagree we score the manufacturer and say so.
