2003 Yamaha R6 Review Pt. 1

Model 2003 Write-Up
2003 Yamaha R6

All new for 2003, the R6 arrived on the scene to very strong competition from the new Kawasakis ZX-6R and Honda CBR600RR. With the ZX-6Rs inverted fork and radial brakes and street racing design of the RBC, the R6 is certainly to be kept honest.
Yamaha shaved weight of the former bicycle using a new method of casting aluminum that forces under high pressure into the mold. This Controlled Fill-casting results in less porosity in the metal, making it stronger and lighter. Revendique the new Yamaha R6 elegant setting a torsional rigidity of a YZR-R7 Superbike, while more than a pound lighter. In addition, only two welds are necessary for reaching the framework versus the previous model of 16. Committed in this regard is the search never slickest oscillating through a stock motorcycle. As context, it is produced by the new casting process. More than 10 mm, it is only 2.5 at its thinnest.
Located in the swingarm black satin is a new five-rays wheel which has been lightened and strengthened. He was travelling on a sticky 180/55-17 Dunlop D208 Sportmax a radial and a 220mm disc which is worked by a two-piston caliper. I could maybe not the fault of tires on the street and liked the rear brake because it’s just a little leverage travel before stopping. The same design which handles rays and the platform as a structural unit is used on the front wheel, and he was travelling on a 120/60-17 D208. Twin 298mm discs, seized by a piece calipers, manipulate braking functions. They are operated by a five-lever adjustable and have a good idea to trail or parking brake. Once the 4-piston calipers begin to bite, but hang on. The incredible speed in which they mail the diminutive Yamaha may terminate a border painful.
No changes break the earth will be found with conventional 43mm cartridge fork, although the air is thinner now. Adjustable preload, compression and rebound damping, the stock parameters are a good combination for the sculpture and canyon highway droning. What has been changed is the shift of the triple clamp 5mm. Wheelbase remains the same if, because the CEO was positioned 5 mm in front to assist the new Yamaha R6 a greater sense of stability. Before now feels completely planted in any situation and not make any sense nervous mid-corner. For gas flicking drive or bike side by side in the narrow Twisties are no grounds for complaint. (The previous R6s could be a little hard skittery under acceleration, it will be interesting to know how the new bike handles acceleration bumps on the circuit. – Ed)
There are no major changes to full-adjustable rear shock. Stock operating parameters very well for me, and outside of a piece of the back on some shots extremely imprecise inter-sections, there is no moaning from this corner. It manages manic acceleration of the turns with ease, and if you can encourage any wobbles and weaves on public roads, you will probably overachievers join the club or get your license race.
Yamaha R6 said the ponies won the last three years as a model, especially because of the addition of R-style fuel injection. The aspiration to piston-type injection uses no fewer than seven sensors to monitor its progress. Once the fuel into the cylinders, it is ignited by candles iridium fired by new direct ignition coils. The AirBox has been enlarged from 7.3 to 7.6 liters and, when under pressure by high-speed air, Yamaha claims a peak power of 123 hp at 13000 rpm.
The interior of the engine, bore and stroke remain the same, with a higher compression ratio and certain combustion chamber to increase recast intake and exhaust efficiency. The intake cam is now a little more lift and is a contributor to the increase in power, particularly in the midrange. The cylinder is cast without sleeve to reduce friction piston, better heat dissipation and a more accurate form. The crankshaft has expanded the passages between the cylinders to reduce the variation in volume of air caused by the action of pumping pistons. To save weight and increase strength, the cylinder and crankcase assembly is a piece of design.
All this high-revving, power generator action establishes a lot of heat. As such, Yamaha added a larger, curved radiator and what they call a ring fan. The ring seals the fan to the contours of an alleged rad for 10-40% improvement cooling. It is also located on the side of the radiator so that more cooling fins are affected by the arrival of air.
The exhaust gases are treated by a quiet four-in-one exhaust system which, like almost everything else on the new R6, has been redesigned to save weight and improve their performance. Weighing about 2 lbs. lighter than the model years, the system is made from a mixture of aluminum and titanium. The double-walled pipes are reshaped head for reducing noise and facilitate the flow, and they send exhaust silencers single which includes a catalytic converter. Yamaha R6 said the new standards than EU2 without power loss.
Visually, the bike is simply breathtaking from any angle, and a dream for photographers during a beautiful sunny days in the canyons of California. Slicker-looking body with new engine revealing side cowls and a more compact tail complete the Gatling beam multi-reflector headlamps. The net result of all these changes is to improve aerodynamics, as well as research powerful fine. Protection against the wind is not too bad, the most senior taken square in the chest six feet of my body. This worked well on the road, as it took pressure from my wrists and shoulders. Put yourself in a Tuck and the wind will own about you, with the mechanical symphony being played out below your chest is the dominant sound.
