On The Pegs VOL. 5 ISSUE 5 - MAY 2020 39 CYLINDER The 72 mm bore cylinder in the TE 300i features a twin valve-controlled power valve system which delivers smooth and controlled power throughout the RPM range. Exhaust port timing has been improved with the combination of an opti- mised, adjustable power valve drive. The cylinder also features two inlet positions at the rear of the cylinder where a pair of fuel injectors are mounted. This ensures efficient combustion resulting in reduced fuel consumption and emissions. CRANKCASES Designed for minimal weight, the die-cast crankcases on the TE 250i engine feature a thin-wall design. To centralise mass, the shaft arrangement has been precisely positioned to harness oscillating masses at the ideal centre of gravity. The counter balancer shaft is also specifically integrated, making for a compact design. Additionally, a new water pump casing improves cooling by optimising the flow of coolant. EXHAUST Tailored specifically for each model using an innovative 3D design process, the header pipe on the TE 300i offers further improvements in geometry and per- formance. This allows for improved ground clearance, while a corrugated surface makes the header pipe resistant to impact out on the trail. The muffler also fea- tures a new aluminium mounting bracket, new internals and less dense packing material for improved noise damping and weight saving. n
