01. Unrivalled power
Engine
Delivering the best spread of power, the TE 250 engine is a firm favourite with enduro riders. Equipped with Throttle Body Injection (TBI), the engine delivers impressive torque while maintaining its high-revving two-stroke character. Inside, the shaft arrangements are positioned to centralise mass, which contributes to the agile handling of this exceptional machine. A counter balancer shaft reduces vibration for maximum comfort throughout every ride.
Cylinder
In addition to being fuelled by Throttle Body Injection (TBI), the 66.4 mm bore cylinder features an innovative electronic exhaust control system that manages the opening of the lateral exhaust ports after the main exhaust port opens for maximum power delivery. Together with a machined finish on the upper contour of the exhaust port ensuring accurate port timing, unrivalled engine performance is assured.
Throttle body
The TE 250 uses a 39 mm throttle body with dual injectors positioned to optimise flow for more immediate throttle response and exceptional rideability. Idle is controlled by the throttle valve, with one low load injector and one top feed injector ensuring maximum performance. Additionally, a Throttle Position Sensor (TPS) offers reliable cold starting with the throttle valve now pivoting on ball bearings for a smoother throttle action.
Oil tank
An electronic oil pump feeds vital 2-stroke oil into the engine. It is located just below the oil tank and feeds the oil via the throttle body, meaning the oil is only mixed with air at this stage. The pump is controlled by the EMS and delivers the optimal amount of oil according to the current RPM and engine load. The oil tank is connected to a filler hose which runs through the upper tube of the frame to a filler cap conveniently located for easy refills.
Crankcase
Designed to be low in weight without sacrificing strength or reliability, the crankcases are made using a high-pressure die cast production process to create a thin-wall design. To centralise engine mass, the shaft arrangements are precisely positioned to harness rotating masses at the ideal centre of gravity.
Exhaust
Tailored specifically for the TE 250 using an innovative 3D design process, the header pipe ensures unrestricted performance and offers improved ground clearance to reduce the risk of impact damage out on the trail. The silencer also features an aluminium mounting bracket and advanced internal construction for excellent noise damping and weight saving.
