| 2012 Yamaha YZF-R1 |
Yamaha has been on quite a roll lately, hasn’t it? After scoring their second AMA Pro Racing American SuperBike Championship in many years, Yamaha wants to build on that momentum by introducing the new YZF-R1.
The 2012 Yamaha 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 harsh intervention from the system. In addition, traction control can aid in reducing tire wear due to less wheel spin. Coupled with the three level D-Mode electronics throttle response control, riders have 21 different choices available to tailor the YZF-R1 to their riding preference.
The 2012 Yamaha YZF-R1 comes with plenty of new styling cues, including a new upper fairing with a revised headlight cowl, giving the bike an aggressive and more modern styling cue. That’s complimented by new LED position lights, new hexagon-shaped muffler caps, and heat shields for a sharper profile at the rear. The footrests have been redesigned for great boot sole contact and advanced rider/motorcycle interface while new silencer heat guards and end caps are re-styled to give the rear end of the bike a more compact look.
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 Yamaha’s MotoGP machines. Unlike typical inline-four engine design, where the two outer and two inner pistons move together in pairs with 180°intervals, 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 engine’s intake efficiency by using the natural airflow during riding to pressurize the air in the air box. This, in turn, contributes to the bike’s power delivery characteristics in the high-speed range, while the design also helps to minimize intake noise. The bike’s fuel-injected engine also takes full advantage of Yamaha’s YCC-T technology, the MotoGP-inspired fly-by-wire technology that’s used to deliver instant throttle response. The YCC-T combines with the YCC-I variable intake system that broadens the spread of the bike’s overall power.
Aluminium Deltabox frame has been designed to offer an optimized rigidity balance to maximize handling performance. This frame is very rigid or stiff at the head pipe, engine mounts and swingarm pivot point. In other areas, material has been carefully removed to allow "tuned flex". Finished in black, this frame boasts a compact 1415mm (55.7") wheelbase. The swingarm pivot location has been optimized to minimize the chain tension effect under hard acceleration, providing more stable handling. The engine is a fully stressed chassis member to maximize handling. Stability, a key to great handling, is unsurpassed while the ability to hold a line under hard acceleration is excellent. This frame features a mix of gravity cast (head stock & front engine mounts & swingarm pivot area), CF (controlled filling) die cast (outer tank rails) and aluminium panels (inner tank rails). Each of these aluminium parts has different flex characteristics in order to provide the rigidity balance the engineers desired.
