Yoshimura set out to give you more usable power and torque across almost the whole rev range.\u003c\/p\u003e\u003cp\u003eThe quoted gains are an increase of 4.5% in maximum power, measured at 12,000 rpm, and 7.7% more maximum torque at 6,700 rpm, so the extra drive arrives where you need it. Power is only part of the story: the machined joints, PTF sound inserts and asymmetrical silencer shape all play a part in performance, and the matte carbon fibre end cap and familiar Yoshimura bark give your KX250 a look and sound of its own.\u003c\/p\u003e\u003ch3\u003eKey features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAsymmetrical silencer:\u003c\/strong\u003e the shape makes the most of internal capacity and houses a resonance chamber that controls sound while adding usable power.
