Yamaha YZF-R description
2012 Yamaha YZF-R1, The 2012 Yamaha YZF-R1 is powered by a 98cc, liquid-cooled 4-cylinder DOHC 16-valve engine with titanium intake valves. Unique to Yamaha is the crossplane crankshaft technology that has proven to be a home-run technology for Yamahas MotoGP machines. Unlike typical inline-four engine design, where the two outer and two inner pistons move together in pairs with 180intervals, the crossplane crankshaft has each connecting rod 90 with a unique firing order of 270 180 90 180. What this does is overcome the inherent fluctuations in inertial torque during each engine revolution, and the accompanying peaky torque characteristics. Instead, combustion torque continues to build, giving the rider more linear throttle response with awesome power and traction out of the corners. A forced air intake system is also part of the whole set-up, increasing the engines intake efficiency by using the natural airflow during riding to pressurize the air in the air box. This, in turn, contributes to the bikes power delivery characteristics in the high-speed range, while the design also helps to minimize intake noise. The bikes fuel-injected engine also takes full advantage of Yamahas YCC-T technology, the MotoGP-inspired fly-by-wire technology thats used to deliver instant throttle response. The YCC-T combines with the YCC-I variable intake system that broadens the spread of the bikes overall power.For 2012, the YZF-R1 receives another benefit from MotoGP technology a seven-level Traction Control System. The system has been developed so the rider does not feel any unnatural or has intervention from the system. In addition, traction control can aid in reducing tire wear due to less wheel spin and when you couple that with the three level D-Mode electronics throttle response control, you have a bike that offers 21 different choices available to tailor the YZF-R1 to their riding preference.

2013 Dakar Rally Results
Mon, 21 Jan 2013Cyril Despres won his fifth career Dakar Rally while helping KTM win for the 12th consecutive time, in taking the motorcycle class in the 2013 edition of the famed off-road race. KTM was again the dominant manufacturer with the top five finishers in the motorcycle class riding motorcycles from the Austrian manufacturer. Despres finished with an overall time of 43:24:22 for the win, including a 15-minute penalty for swapping an engine after the one he was using in his KTM 450 Rallye failed.
Our Magnificent seven
Wed, 16 Feb 2011Remember to dust your Union Jacks down if you happen to be visiting any Grand Prix this year as we have no less than seven youngsters to cheer on in the junior Moto GP classes. I don’t think we’ve ever had this many ‘yoofs’ in the GP paddock so let’s hope they can do the business and bring an end to our long drought of Grand Prix titles. And that could be soon as Scott Redding is already a hot favourite for the 2011 Moto 2 championship on his Marc VDS Suter machine.
And in my front room this evening...
Tue, 24 Nov 2009NO IT'S NOT an illusion: you're looking at the 1981 Yamaha OW53, ridden by double World Champion Barry Sheene in the first three rounds of the '81 500GP championship. The bike's owner, aircraft engineering entrepreneur Chris Wilson, has lent the £100,000 GP machine to Visordown for our stand at this year's NEC Motorcycle Show - 27th November to 6th December 2009. Sheene raced the bike in the 1981 championship, where he finished fourth at Salzburgring, sixth at Hockenheim and third at Monza.
