2012 Yamaha YZF-R1 Review
The new for 2012 Yamaha YZF-R1 will be a revelation even for experienced track riders. Changes have been made to the ECU and a new traction control system has been fitted on the new R1. The fairing is now more aggressive and so are the new LED lights. Other changes are a new muffler covers and a triple clamp inspired by MotoGP. The R1, which was the superbike champ in 2011 with its unusual uneven firing order and cross plane crank evolves in the new year with new settings for the ECU and fitment of traction control.
Features of 2012 Yamaha YZF-R1
These changes have made the 2012 Yamaha YZF-R1 easier to ride for experienced riders and they can now fully explore the potential the bike has to offer and revel in the uniqueness provided by the cross plane engine.
With two consecutive superbike titles in its kitty and taking inspiration from MotoGP more than any time before, the 2012 R1 is the most advanced production bike at the moment.
The R1 benefits from MotoGP technology like the 7-level traction control system and also the option to be had in the 50th anniversary livery of grand prix for the special edition R1. This includes a anniversary emblem on top of the tank and a number plate showing the number your bike is because only 2000 GP anniversary special 2012 Yamaha YZF-R1 will be built. The fuel consumption will be around 14kpl.
The traction control has seven levels so as to make the rider not feel any harshness or suffer from any undue intervention from the TC. Traction control will also reduce tire wear as it will cut down the wheel spin. Apart from this, the rider has a 3-level throttle response control and with the TC, he has 21 choices to tailor the bike to his riding style. The R1 uses the MotoGP-inspired technology for the throttle.
This fly-by-wire tech delivers instantaneous response for maximum power spread. The aluminum frame is very rigid to enable keen cornering and superlative handling. The suspension set up has also been inspired by MotoGP and this is made up of SOQI forks at the front and the trick is that they offer independent damping.
While the right fork is used for rebound damping, the left looks after compression damping. The sound made by the exhaust is unlike any made by an inline 4-cylinder supersport in production.
The engine is the ultra-compact and ultra-light DOHC, 16-valve, 998cc, water-cooled, in-line 4-cylinder. It is incline at 40 degrees and the crankshaft is of the crossplane style. The firing order is uneven and both of these features figure prominently on the MotoGP Yamaha M1 racer which is the current winner. The main advantage of crossplane crank is uneven firing order. In normal inline four-cylinder bikes, the firing order is 1,2,4,3 with an interval of 180°. But in the R1, the firing order is 1,3,2,4 cylinders.
The intervals are also uneven: 270°/180°/90°/180°. For the rider, this translates into as linear torque as possible and great throttle control. This set up enable communication between the rider and machine like never before. On the track, this cornering is now outstanding. The main goal the engineers set out to achieve was to give the 2012 Yamaha YZF-R1 great controllability and not only increased horsepower. What was the use of increased horsepower when you can’t handle it?
The fuel injection system, built by Mikuni, has been revised and now has two injectors. One set are the primary injectors which feeds two secondary injectors. This set up is also used on the M1 GP bike and the R6. The primary injectors are located in the throttle body while the secondary are placed in the air box, near the intake funnels which are computer controlled.
The primary injector has four spray holes which maximize the petrol atomisation process, while the second injectors start functioning in the mid range and above when more fuel is needed. The transmission is 6-speed and the gear ratios are optimized for outright performance.
The ram-air system feeds the intake system fresh air through ducts placed by the side of the headlamps. The increase in speed creates a pressurized air box and this aid the engine in developing maximum output.
Brakes are six-piston calipers full floating 310mm at the front and single piston slide type 220mm at the rear. Lightweight five-spoke magnesium ally wheels (17”)are employed and these are shod with premium sport tires.
$14,490 for the anniversary bike while the rest of the range starts at $13,990 and goes up to $14,190.
