2-STROKE ELECTRONIC FUEL INJECTION SYSTEM

Engine Management System (EMS)

The EMS features a new electronic control unit (ECU) that is responsible for a number of functions. Gathering information from the throttle position sensor, the ambient air and intake pressure sensors and the crankcase pressure and water temperature sensors, it automatically compensates for temperature and altitude changes eliminating the need to modify carburettor jetting. A standard map select switch allows riders to customise power characteristics according to personal preference or in varying conditions.

The throttle body
The throttle body

Throttle Body

Both models feature a 39 mm Dell´ Orto throttle body that is linked to the new dual cable handlebar throttle assembly. With a new throttle position sensor (TPS) relaying airflow data to the ECU, the system ensures optimal air, fuel and oil mixture. Additionally, the system features a bypass screw for idling speed regulation, with a cold start device providing more air for cold starts.

Oil Tank & Oil Pump

Vital for crankshaft, cylinder and piston lubrication, the 2-stroke oil is stored in a separate tank that together with an electronic oil pump eliminate the need for pre-mixing. With its filler tube running through the upper frame, the 0.7 litre tank contains oil for five full tanks of fuel depending on riding conditions. Controlled by the EMS, the oil pump delivers the ideal amount of oil according to the current RPM and engine load reducing waste as well as excessive smoke from the exhaust. The average ratio achieved for fuel/oil is 80:1.

Fuel Tank

The two models feature a fuel tank made of translucent plastic so the fuel level can be checked quickly and easily. The fuel tank has a 9.25 litre capacity and houses an integrated fuel pump and fuel level sensor.

FEATURES AND BENEFITS – ENGINES – 2-STROKE

TE 250i/TE 300i

Engine

 The 250cc and 300cc 2-stroke engines set the benchmark for unrivalled power and lightweight construction. The engines feature precisely positioned shaft arrangements for optimal mass centralisation, a counter balancer shaft to reduce vibrations, a twin-valve controlled power valve and a 6-speed enduro gearbox.

Cylinder

 For MY18 two inlet positions are located on the transfer ports at the rear of the cylinder where a pair fuel injectors are mounted. The injectors deliver the fuel downwards into the transfer ports, which guarantees excellent atomisation with the air travelling upward to the combustion chamber. This ensures a more efficient burn of the air/fuel mixture resulting in reduced fuel consumption and emissions.

The 66.4mm (TE 250i) and 72mm (TE 300i) bore cylinders feature twin valve controlled power valve systems, which deliver smooth and controlled power throughout the RPM range. For different conditions and rider preference, alterations to the power delivery can be made by simply changing between the three supplied springs.

 Piston

The lightweight piston is perfectly matched to each cylinder transmitting minimal oscillating mass and ensuring high levels of reliability and performance.

  • Piston → High reliability and performance

Engine Casings

Both engines are designed to improve mass centralisation. As a result, the lightweight, die-cast engine casings are developed to accommodate the shaft arrangements in the ideal position, centralising oscillating mass and improving ride-ability.

Additionally, the counter balancer shafts are integrated in a very compact manner having little effect on the overall design.

  • Engine casings → Mass centralisation, improved rideability

Counter Balancer Shaft

The engines house a laterally mounted counter balancer shaft. The balancer significantly reduces vibration resulting in a smoother and more comfortable ride.

  • Counter balancer shaft → Significantly reduced vibration

Crankshaft

The crankshafts feature a 72 mm stroke and are balanced in conjunction with the counter balancer shaft for minimum vibration. By incorporating a heavier ignition rotor, the crankshafts produce more inertia than on the TC 250 MX model, which improves control in the lower RPM range.

Gearbox

A 6-speed gearbox features enduro specific ratios with an innovative shift lever reducing dirt build up and guaranteeing easy operation in all conditions.

  • 6-speed gearbox → Enduro specific ratios

Clutch

The TE 250i and TE 300i feature a DDS (damped diaphragm steel) clutch. The clutch uses a single diaphragm spring instead of the more common coil spring design, resulting in a much lighter clutch action. This design also incorporates a damping system that increases both traction and durability. Assisted by the Magura hydraulic clutch, the system provides a light and modular feeling, which is almost maintenance and adjustment free.

  • DDS clutch → Light action with integrated damping system, perfect traction & reliability

  • Cylinder → innovative power valve design delivering class leading performance

Crankshaft

With both models featuring 54.5 mm of stroke, the crankshaft is perfectly balanced and delivers more inertia compared to the TC 125 design thanks to a heavier ignition rotor which provides more controllable low end power.

  • Lightweight crankshaft → very little vibration

Crankcases

High-pressure die cast production processes result in a thin wall thickness and a low overall weight for both engines. The shaft arrangements are located in the ideal position reducing the effect of oscillating mass for more precise handling. The historical Husqvarna logo adorns the bronze finished crankcase covers.

  • High pressure die cast production process → thin walls resulting in light weight, while maintaining strength
  • Shaft arrangement → mass centralization, precise handling

Starter

The design of the TX 125 engine allows for the optional fitment of an electric starter. The starter will be available in a Husqvarna accessories kit and include all the necessary equipment needed to make the modification.
