The new YZ125 is the fastest, lightest and most agile 125cc production motocross bike ever built by Yamaha. This winning 2-stroke is completely redesigned to give you stronger and more useable power – and the ultra-slim chassis is equipped with powerful brakes and refined suspension that deliver the performance you need to get on the podium.
Featuring all-new engine internals as well as a redesigned YPVS (Yamaha Power Valve System) and a new Keihin powerjet carburettor for explosive acceleration, the YZ125 develops a higher peak power that keeps you way out front – and a slicker shifting 6-speed transmission and revised gear ratios help to shave precious seconds off your lap times.
Its sharp new bodywork is slimmer than ever, giving you increased controllability on the ground and in the air – and the flatter seat and new sidepanels allow you to move easily around the bike when braking and accelerating hard. The YZ125 gives you more power and increased agility – now just add your ability and prepare to enter the victorYZone!
