yamaha YZF R125

Re-Define Your Reality.

The YZF-R125 engine is the most sophisticated 125cc design we’ve ever built. Its Variable Valve Actuation system and high-flow cylinder head deliver strong low rpm torque with exciting high rpm power – giving quick acceleration, fast pick up, a high top speed and outstanding fuel efficiency.

Aggressive new YZF-R1-derived bodywork and dual LED headlights project a strong and forceful look – and the refined Deltabox frame together with a new aluminum swingarm and wider 140-section rear tyre reaffirm the new YZF-R125 as the ultimate lightweight supersport. Re-define your reality.
