KTM Updates 2027 50cc-Class Bikes, but Gap for 65/85cc Riders
The SX-E 2.12 opens the range at $3,895 and the SX-E 5 tops it at $9,995. Beyond that there is nothing for 65 and 85cc riders until the full-size Freeride E, at $19,495.
KTM’s 2027 electric range is in Australian dealerships now. Three bikes: the SX-E 2.12 at $3,895, the SX-E 5 at $9,995, and an all-new Freeride E at $19,495.
Meet the SX-E 2.12
The newcomer is the SX-E 2.12, announced to the press on 6 and 7 October.
To understand the balance bike nomenclature, KTM uses the front wheel size as the suffix on its balance bikes — SX-E 1.12, SX-E 1.16. The 2.12 is an SX-E 2 running a 12-inch front wheel in place of the 10-inch; the rear stays at 10 inches.
The powertrain on the SX-E 2.12 is identical to the SX-E 2: the same 1.8 kW hub motor, the same 90 mm of front travel and 70 mm at the rear, the same 140 mm discs, the same 35 minutes to 80 per cent. What changed is the chassis around it. The seat goes from the SX-E 2’s fixed 470 mm to an adjustable 536 to 566 mm. There is 52 mm more room between seat and pegs, and 168 mm of ground clearance. It weighs 27 kg. Maximum torque is 50 Nm, measured at the hub.
The safety kit is what parents will read twice. A roll-over sensor cuts drive in a crash. A wrist lanyard kills the motor if rider and bike part company. The throttle must be rolled forward before the motor will arm, and the bike buzzes the rider’s hand to say it is live — a feature many adults would welcome on full-size bikes to avoid the dreaded ‘whisky throttle’ off the stand! Levers adjust for small hands, and the pads are cross-compatible with high-end bicycle pads.
What Australia doesn’t get
Here is where the Australian range has a gaping hole on paper.
KTM’s international site lists seven electric models under kids’ motocross and balance bikes: the SX-E 5, SX-E 3, SX-E 2 and now SX-E 2.12, plus three balance bikes, the SX-E 1.20, 1.16 and 1.12.
Australia takes two of those seven. The SX-E 2.12 is the new arrival. The SX-E 5 was already here. The other five — the SX-E 2, the SX-E 3 and all three balance bikes — don’t come to Australia at all.
So the 2.12 is not a rung added between the 2 and the 3, the way it reads overseas. In Australia it is the entry point to the whole SX-E range — and the next step up is the SX-E 5 at $9,995.
That is a $6,100 jump with nothing between it.
The SX-E 5 is a different class of machine: 5 kW, 13.8 Nm, an 84-cell 907 Wh pack, WP XACT air forks with 205 mm of travel and 193 mm at the rear, 259 mm of ground clearance and a 634 to 682 mm seat.
Do not read those torque figures against each other. The 2.12’s 50 Nm is hub torque, straight at the wheel. The SX-E 5’s 13.8 Nm is motor output before a chain and sprocket do their work. Different measurements of different things.
There is still nothing for the 65 and 85cc classes. Motorcycling Australia lists the SX-E 2 and SX-E 5 in the 50cc Auto/Demo class. The next KTM electric on the list is the Freeride E-XC, in the Big Wheel 85cc two-stroke and 150cc four-stroke class: a full-size bike at $19,495. For a young rider outgrowing the SX-E 5, that is the next step.
The Freeride E is the real 2027 news
KTM calls the 2027 Freeride E all new, with a newly developed chassis and an upgraded 5.5 kWh interchangeable pack, coming in at $19,495. It makes 19.2 kW peak and 8.3 kW nominal, 37.6 Nm, runs WP XACT 43 mm split forks and a WP XPLOR PDS shock with 250 mm of travel, BRAKTEC brakes at 260 front and 220 rear, and a 910 mm seat. The pack weighs 29 kg, carries an IP67 rating and is good for a claimed two to three hours of enduro riding. This aligns it roughly with a model like the Sur-Ron Ultra Bee HP, which makes 24.5 kW peak and which our Bike Index lists at $10,490 plus on-road costs.
Charging is the catch. Eight hours for a full charge on a household supply through the 660 W charger, and four to five hours for 20 to 80 per cent. The fast-charging line in KTM’s electric marketing belongs to the minis, not this.
And the one that didn’t move
While the 2 and the 5 went to 2027 and the Freeride E was rebuilt, the SX-E 3 is still listed at model year 2025. Two model years without renewal. It isn’t sold here either.
So KTM has spent its 2027 effort at both ends of the electric range and left the middle alone — which is exactly the part of the ladder an Australian junior rider has to climb.
