YamahaYZF R125

Description

YZF-R125 – The R-series start here
With its R-series styling, sporty performance and handling, the YZF-R125 is the perfect introduction to supersport riding.

Its liquid-cooled, 4-stroke, 4-valve, single cylinder, SOHC engine is tuned to deliver free-revving performance. Like all R-series bikes, it features a lightweight Deltabox frame; linked to a cast aluminium swinging-arm it gives the R125 class-leading handling.

Lightweight 5-spoke wheels help to minimise unsprung weight to give impressive roadholding, while effective stopping power comes from a large diameter 292mm front disc and 230mm diameter rear disc.

Features
•Free-revving, fuel injected 4-stroke engine
•Aggressive R-series styling
•6-speed transmission
•Deltabox frame and aluminium swinging arm
