Yamaha WR description
2013 Yamaha WR250R, 2013 Yamaha WR250R Technologically Advanced Dual Purpose Machine The WR250R offers the best of both worlds, a light and nimble aluminum frame, a powerful liquid engine with titanium valves, and long travel suspension for off-road adventures and all the equipment to make your on-road travels just as much fun. Features Directly descended from our YZ motocrossers and WR off-road machines, the WR250R is here to make Yamaha s off-road prowess street accessible. Not exactly an enduro model and not a streetbike either, the WR250R is for riders who ride off-road more than on. 250cc liquid-cooled, DOHC engine with two titanium intake valves and two steel exhausts, forged piston and plated cylinder for outstanding durability. Pentroof combustion chamber with downdraft-type straight intake helps make excellent power across the rev band, with maximum power at 10,000 rpm. First use of fuel injection on a 250 Yamaha on/off-road bike. The system relies on input from a crank sensor, intake air pressure sensor and throttle position sensor feeding a compact ECU to provide optimum combustion. An ECU-controlled EXUP exhaust valve, along with an electronic intake control valve, broadens the powerband. High lift cams have WPC surface treatment in which the surface is sprayed with fine powder at over 100 meters per second to increase surface hardness. Three-axis engine layout keeps the engine compact. Wet sump tucks between frame rails to keep the engine height down. Rare earth-type ACM alternator keeps the weight down while providing all the current needed to run the FI and lighting systems. Direct ignition coil sits atop the spark plug another first on a Yamaha on-off road model.

BSB 2012; Mystic Mac investigates
Tue, 03 Jan 2012In my opinion, the smartest move in the BSB off season has to be Michael Laverty moving from Swan Yamaha to HM Plant Honda. With a ban on electronics for 2012, and in particular traction control, WFR's Graham Gowland has already proved to Laverty how competitive an EVO spec Fireblade can be - so I’m tipping both these riders to be bang on the money at the Brands Hatch season opener in April. Unlike BMW, Kawasaki and Yamaha, Honda have deliberately developed their road-going Superbike without electronics to give a user friendly feel with good mechanical traction, so it’ll be interesting to see how the opposition copes with their high-tech trickery stripped off.
Japan-only 'race base' R1
Thu, 22 Nov 2012Yamaha have proved once again that all-black bikes never fail to please, this is the Japan-only R1 supplied to you by Yamaha if you're going to be racing in the All-Japan Superbike Championship. So that'll be none of us getting one of these, then. The good news: you can choose between an R1 or an R6, they're supplied black and with a racing ECU and loom.
