4-stroke, 4-valve, single cylinder, liquid-cooled, SOHC engine is tuned to deliver free-revving performance Yamaha YZF-R125 2011.
The YZF-R125 also has real racing pedigree, featuring the agressive styling of the R6 and R1 as well as a MotoGP inspired mid-ship exhaust.
The YZF-R125’s advanced engine combines a 4-valve cylinder head and fuel-injection for the best possible performance. The short stroke layout gives the engine a free-revving character, which when connected to the 6-speed gearbox, delivers lively acceleration.
With R-series style front cowling and twin fox-eye headlights, the YZF-R125 has the same aggressive supersport styling as the R1 and R6. Unlike many 125cc bikes, the R125 is built on a full-sized chassis providing a more comfortable riding position – especially for taller riders.
Yamaha is committed to using high-specification components – like the large diameter 292mm front disc brake units on the YZF-R125. The compact twin-pot caliper design on the front-brake combined with the 230mm rear disc ensures smooth, controlled braking at a range of speeds and assured stopping power when you need it.
The mid-ship Yamaha YZF-R125 2011 exhaust muffler contributes to centralise the bike’s mass for balanced handling, and houses dual catalysers for cleaner emissions. In addition, an Air Induction System introduces air into the exhaust for more complete combustion of exhaust gases, lowering emissions even further.
The combined digital and analogue panel Yamaha YZF-R125 2011 speedometer provides a clear view of all the bike’s vital functions at a glance.
The Yamaha YZF-R125 2011 features a lightweight Deltabox frame which delivers an optimum balance of strength and rigidity for class-leading handling performance. Complementing the frame is a lightweight cast aluminium swinging arm that allows the link-type rear suspension system to operate more efficiently and deliver more responsive handling qualities.
