The Yamaha R4 is a true sports bike.It gets its styling from Yamaha R series DNA.The rear part is from the Yamaha 1000 cc super bike R1 and the fairings on the sides and front are derived from Yamaha R6 and the rear view mirrors are from Yamaha YZF R125.The most interesting feature of the bike is dual disc brakes on the front.In general 250 c bikes have only a single disc brake at the front.The split seat is positioned at a low height.The turn indicators are attached to the front fairing.The rear number plate holder is of ladder type which is stylish and sporty.R4 is written on the sides and the numeric 4 extends to the end of the fairing which is a symbolic representation of racing characteristics of the bike.The Yamaha branding is present on the under cowl of the bike in white color.The fuel tank is two piece.The lines starting from fuel tank extend towards to the front fairing giving the bike a more R series appeal.The exhaust is mid-ship free flowing is from Yamaha R6.udgng by the foot pegs and the position of the seat the posture is sporty.And one has to lean forward to grab the handles.
The bike is powered by a 250 cc 4-stroke liquid cooled single cylinder engine with fuel injection.The engine has 4 valves controlled my an advanced DOHC camshaft.Cross-plane crankshaft seen in Yamaha R1 might make its way into this bike.The technical specifications are not available as the bike is mostly targeted at European market in the learner’s class for the age group of 18-21 years the bike cannot have more than 33.5 bhp.So one could safely assume Yamaha may get the power output not less than 27 bhp.As if it falls behind 27 bhp it would be hard to gain a market share as the CBR 250R gives competition if the two bikes have the same power output.The final drive is chain.
