Husqvarna
TC 250

The benchmark

Engine

249 cm³, 53 hp, 23.9 kg — the pinnacle of 250 two-stroke performance, and the benchmark for torque out of a corner. EFI takes jetting off the job list, cuts running cost and improves reliability; electric start means a stalled moto restarts as fast as it stalled. No four-stroke rebuild bills, either.

Ports, electronically

Cylinder

66.4 mm bore, and with EFI the traditional power valve gives way to an electronic exhaust control system that opens the lateral ports before the main port for strong, controllable power. The upper contour of the exhaust port is machined for accurate port timing — the reason two cylinders of the same size do not make the same power.

Light, balanced

Crankshaft

The crank is built light for throttle response, and the rotating masses — crankshaft flywheel, rotor and counter balancer shaft — are balanced against each other rather than each on its own. The engine runs smooth without carrying dead weight to do it, and it picks up revs the way a two-stroke should.

Thin walls, strong case

Crankcases

High-pressure die-cast cases with thin walls for minimum weight, and the shaft arrangement placed for mass centralisation. Symmetrical engine mounts feed into the flex characteristics of the chassis, so the engine works as part of the frame rather than as a lump bolted into it.

No buzz

Counter balancer shaft

A laterally mounted counter balancer shaft takes the buzz out of the two-stroke. Less vibration through the bars and pegs means less arm pump, less numb hands, and a rider who is still sharp in the last five minutes of the moto — a smoother, more comfortable ride that shows up on the lap chart.

Hook up, hold on

DDS clutch

Dampened diaphragm steel clutch — a single diaphragm pressure plate instead of coil springs, with a damping system built in for traction and durability, all inside a CNC-machined steel basket. Compact engine, consistent lever feel, and plates that wear evenly.

Five, by Pankl

Gearbox

Five-speed gearbox made exclusively by Pankl Racing Systems for the highest level of durability and smooth, precise shifting. The gear-lever tip is shaped for leverage and does not pack with mud, so the box still shifts cleanly at the end of a wet moto — the way it did on the first lap.

Grip it with your knees

Bodywork

Bodywork built for the length of a moto, not a photo shoot. Smooth contact points in the rider triangle let you squeeze the bike with your legs instead of fighting it, which is where fatigue goes. The radiator shrouds carry in-mould graphics that do not peel, the seat is tall and wide for movement, and the high-grip cover keeps you forward under acceleration.

Breathe in deep

Airbox

One-piece airbox, stiff enough not to deform under load, so the intake tract keeps the shape it was designed in and the engine gets an unrestricted feed without exposing the filter. The Twin Air filter comes out without tools — pull the left side panel, check, replace, done.

Same bite, every lap

Brembo hydraulic clutch

Brembo hydraulic clutch. Free play is compensated automatically, so the bite point is in the same place cold, hot and after twenty hard laps, and the plates wear evenly. Near maintenance-free — and one less thing to fiddle with on the line.

260 up front

Brembo brakes

Brembo callipers machined from single pieces of aluminium front and rear, on a 260 mm front disc and a 220 mm rear, both cut to shed mud rather than pack it. Strong, consistent stopping in every condition, and a rear pedal built to survive being dragged through ruts.

An exclusive bend

ProTaper handlebar

ProTaper aluminium bar in a bend developed with Husqvarna Motorcycles and used on nothing else. Ø 28/22 mm tapered, light, class-leading strength, and built to resist fatigue — the bar's and yours. Comfort at the bars is not a luxury; it is where the last five minutes of a moto are won or lost.

No glue

ODI grips

ODI lock-on grips with the throttle mechanism built in, fitted without glue or safety wire — a grip change between motos is a two-minute job. Free play is adjusted at the throttle assembly, and you can swap cams for a quicker or slower throttle action to suit the rider and the track.

Boot hold

Footrests

CFD-shaped footrests, extra wide for control when standing, on a narrower mounting in the frame layout. Less to catch on a deep rut, a take-off when scrubbing, or a trackside barrier — and a little less weight while it is at it. Boots stay where you put them, in the wet as well as the dry.

No jets

Electronic fuel injection

Keihin 39 mm throttle body with a Vitesco ECU that reads the running condition constantly and delivers the right air/fuel ratio every time — no jetting, and no rich running on long climbs or descents thanks to the redesigned reed valve. Two maps on a handlebar switch, white for Map 1, green for Map 2.

Press and go

Electric start

No kickstart at all — guaranteed, easy starting in any condition. A 12.8 V 2 Ah lithium-ion battery sits under the seat near the centre of gravity so it does not upset the handling, and the same handlebar switch starts and stops the engine. Stall in a rut, press, go.

White or green

Map switch

Map 1 (white) is the standard: linear, predictable power. Map 2 (green) is sharper, with quicker throttle response and a more explosive delivery. One button on the handlebar-mounted switch toggles between them — on the line, in the gate, wherever.

Small, light, fast

EMS

The engine management unit is small, light and quick at processing what the sensors tell it. Built in is a rollover sensor: go down hard and the ignition is cut and the engine stopped, so the bike is not running away from you on its side.

Count the hours

Hour meter

An hour meter with a fuel-level indicator built in, shown on the FI status LED. It counts the hours the service schedule is written in — so a team knows exactly where every bike is — and it warns you when the tank is getting low before the engine does.

Thumb it

Start/stop switch

One combined start/stop switch on the right of the bar, thumb-operated. No separate kill button to break off in a crash or hit by accident when you are up on the pegs — start it, stop it, same switch. Simpler for the rider, and one less part on the bars to replace.
