With the 2011 Yamaha YZF, the Japanese manufacturer continues its tradition of bringing insane MotoGP technology to some of the best production bikes available. The Yamaha YZF underwent a significant redesign in 2009, so don’t expect there to be a ton of changes with this model. Don’t let that stop you, however, as this is one amazing bike that in 2009 was already light years ahead of the pack.
The Yamaha YZF is available in two sub-models for the 2011 production run – the YZF R6 (599cc) and the YZF R1 (998cc). While there are some striking differences between the bikes in terms of fairing, headlights, engine, and other attributes, both bikes feature Yamaha's trademark razor-sharp styling, together with a superior fit and finish that only makes what's under the seat all the more enjoyable to ride.
The Yamaha YZF R6 is powered by an ultra-compact, DOHC, 16-valve, liquid-cooled, in-line four-cylinder with titanium valves. With a 67mm bore and 42.5mm stroke, this is one fast-revving power plant that features a red line set at an unbelievable 16,000 rpm. The Yamaha YZF R1, on the other hand, packs a larger 998cc version of the motor. The R1 is also the only production bike to feature a crossplane-style crankshaft, with an uneven firing order. The end result is an engine that produces the most linear torque possible. When coupled with the Japanese company's trademark YCC-T throttle system, riders enjoy instantaneous throttle response and increased engine control.
The bike's exhaust system consists of 31mm intake valves and 25mm steel exhaust valves. With valve angles set at 11.5 degrees on the intake side and 12.5 degrees on the exhaust side, the combustion chamber is compact, efficient, and optimized for premium engine performance.
The 2011 Yamaha YZF has an aluminum Deltabox frame that's been designed with a 56-degree lean angle. While certain components of the frame are highly rigid, others are designed to allow ""tune-flex,"" which helps maximize handling and performance. On the 2011 R1, the engine's location has been slightly altered to improve the bike's front-to-rear weight ratio, balance, and center of gravity.
With a bike as powerful as the 2011 Yamaha YZF, you’re going to need plenty of braking power to stop. Luckily, Yamaha equips its bikes with the best. Both bikes feature radial-mount, monoblock, four-piston calipers by Brembo, with dual 310mm discs on the front end and a single-piston caliper 220mm disc on the rear. The bike's suspension is built to magnificently handle the road, and features MotoGP-inspired SOQI (on R1 only) front forks with independent damping and a rear single shock with bottom linkage for optimum performance.
Once again, Yamaha outdoes itself with the 2011 YZF model lineup. Offering a brilliant collision of design, style, speed, aggressive handling, and unbeatable performance, the YZF is as close as you can get to MotoGP in a production bike. Take note – no other production bike can boast being ""track ready and street smart"" quite like the 2011 Yamaha YZF.
