2005 Yamaha R1
2005 Yamaha R1
The R1 was a totally new machine in 2004, and its impact was immediately felt in the super sport world. The 2004 – R1 dominated Superbike racing in Canada by winning 6 out of 8 eight races and once again powered Pascal Picotte to the Canadian Superbike championship. Not only was the R1 dominate on the racetrack, but it also was a huge sales success as well. For 2005 the R1 has received some minor ”tweaking” to insure that it maintains it position as the dominate open class super sport machine in Canada. And speaking of insurance, the new 2005 R1 features a new immobilizer ignition system that will reduce the possibility of theft and at the same time addresses some of the insurance cost and availability concerns that sport bike riders are currently facing.
Obviously, with its 998cc, 180-horsepower ram-air fuel-injected engine, the YZF-R1 is intended for riders who like their performance straight up.
Not so obvious is that years of Yamaha liter-bike evolution have produced a machine that offers unsurpassed refinement, control, and confidence.
Optimum weight distribution, along with advanced chassis design and power management software, produce a bike that puts the horsepower into harness and then reins it into control with the latest in braking hardware.
Add to that the sculpted fuel tank and narrow frame and you have an organic machine that nearly disappears beneath you at speed.
The result is the winner of Roadracing World and Motorcyclist magazines’ Open-class comparison tests.
Take a look at the Features & Benefits that make the R1 the ultimate motorcycling expression on the planet.
Features & Benefits
· Ultra-lightweight, compact, 998cc, DOHC, 20-valve, liquid-cooled, in-line four-cylinder engine produces an incredible 180 horsepower (ram air) 172 horsepower (no ram air) at an amazing 12,500rpm.
· cylinder head design utilizes new valves, valve angles, re-designed squish area, and new intake and exhaust ports for increased performance.
· Steep valve angles (intake 1 = 8.75 degrees / intake 2 = 15.75 and exhaust = 11 degrees) produce a more compact combustion chamber.
· Squish area has been optimized for maximum engine performance. The compression ratio is 12.4:1.
· Special lightweight, high lift, high performance intake and exhaust cams. Bore and stroke dimension are 77 x 53.6mm.
· Revised short skirt, lightweight piston design features special ribs in the piston pin area for great rigidity.
· Connecting rods are carburized and use a nutless design. The lower end ”cap” of the rod is made from the same piece of material as the upper portion, this design is known as ”fracture splitting” and the upper rod and lower cap must remain as a set. This design aids establishing true big end roundness.
· Closed deck cylinder design allows the cylinders to spaced more closely together, allowing a narrower engine package. The cylinder block is a stand-alone piece. The benefit if this design is improved sealing, and to improve serviceability.
· Ceramic composite cylinder bores ensure great heat dissipation for consistent power delivery and reduced friction.
· Lightweight crankshaft means super quick engine response.
· The ACM or alternator is located on the backside of the cylinder block to reduce crankcase width thereby maintaining the ability for very aggressive lean angles and a low center of gravity. The compact ACM uses rare earth magnets and spins at 1.24 times the engine rpm to produce ample electrical current to power the bikes electrical requirements.
· Narrow design crankcases allow for maximum lean angles.
· Specially designed starter motor rotates the crank via a gear on the ACM rotor.
· Denso fuel injection system uses 45mm throttle bodies fitted with T.P.S. (Throttle Position Sensor). This fuel injection system, which was introduced in 2004 uses dual valve throttle bodies with motor driven sub or secondary throttle valves for optimum throttle response.
· The actual injectors are Denso ”long nose” type injectors with a high dynamic range and 4-spray holes for improved power and response across the entire rev range. The long nose design locates the injectors closer to the throttle body.
· The fuel injection’s lightweight Electronic Control Unit (ECU) utilizes a powerful 32-bit processor for faster control of the injection process. The compact design reduces weight.
· For 2005 the ECU settings have been revised for better engine feel at high rpms. The new settings also accommodate the new immbolizer ignition.
· Twin electrode NGK CR9EK spark plugs maintain the proper clearance between the plug tip and the top of the piston.
· ”Stacked” 3-axis gearbox / clutch design stacks input/output shafts to create a low center of gravity and keeps overall engine size shorter front to back. As a result, the stacked design gives the engineers the freedom to place the engine in the frame for optimum front to rear weight balance and thereby maximizing handling.
· Compact close-ratio 6-speed transmission features optimized gear ratios for maximum performance.
· Compact, large-capacity clutch ensures consistent, positive engagement.
· A multi plate clutch is used, This design uses coil springs (5) and paper based fiber plates (9) to reduce weight.
· ”Ram Air” system ”force feeds” cool air via dual ducts located below the headlights into the intake system. As speed increases the air velocity in the system increases and pressurizes the air box. This ”force fed” air helps the engine develop maximum high rpm power.
· Specially designed 5.9-liter air box maximizes performance. A viscous type air filter is utilized.
· 4 into 2 into 1 into 2 titanium exhaust system maximizes power output, reduces weight and improves aerodynamics. The dual under seat mufflers provides an aggressive sound and a great styling touch. The system contains a 3-way catalytic converter located in a special section of the exhaust pipe (made of stainless steel) just ahead of the actual muffler. The catalytic converter reduces harmful HC exhaust emissions.
· EXUP System (Exhaust Ultimate Power Valve) utilizes a single axis titanium butterfly valve. This design reduces weight and maximizes cornering clearance.
· High-efficiency curved radiator features dual ring-type fans for maximum cooling efficiency. This rad and fan design produces more airflow than conventional designs to maintain optimum engine temperatures for consistent performance.
· Large liquid-cooled oil cooler maintains stable lubricant temperatures for extended engine life. Convenient cartridge style spin-off oil filter.
· Convenient clutch cover sightglass ensures easy oil level inspection.
· Direct ignition coils (ignition coil is built into the spark plug cap) reduce weight while iridium spark plugs and high-output magneto deliver a hot strong spark for reliable firing.
· Aluminum Deltabox frame has been designed to offer great rigidity and maximize handling performance. Finished in black, this frame boasts lightweight and a 600cc spec 1395mm (54.9”) wheelbase. The engine is a fully stressed member and the angle of the engine mounting is 40 degrees.
