In 1987, the bike underwent a significant remodelling in which the V-angle between pistons was raised to 112\u00b0, which left enough space for four 36\u00a0mm Keihin carburettors in the centre of the V. This modification led to improved air intake, which in turn increased its performance. Another important adjustment made was the direction in which the crankshafts rotated to counteract the gyroscopic effects of the wheels, improving the bike-s performance in run-off areas. Even though the bike\u2019s manoeuvrability improved, it did create the need to add an additional shaft to invert the spin direction at the engine\u2019s exit, which slightly decreased its power.<\/p>\n<p>This bike handed Wayne Gardner the first position that year, so it was safe to assume the changes made were headed in the right direction.<\/p>\n<figure><picture style=\"padding-bottom: 55.801435406699%; background-image: url('https:\/\/bxrepsol.s3.eu-west-1.amazonaws.com\/static\/2022\/08\/30043254\/nsr500-repsol-2.jpg');\"> <img decoding=\"async\" src=\"https:\/\/bxrepsol.s3.eu-west-1.amazonaws.com\/static\/2022\/08\/30043254\/nsr500-repsol-2.jpg\" \/><\/picture>\n<picture style=\"padding-bottom: 55.801435406699%; background-image: url('https:\/\/bxrepsol.s3.eu-west-1.amazonaws.com\/static\/2022\/08\/30043254\/nsr500-repsol-2.jpg');\"><img title=\"nsr500-repsol\" alt=\"chasis nsr500\" data-srcset=\"https:\/\/bxrepsol.s3.eu-west-1.amazonaws.com\/static\/2022\/08\/30043254\/nsr500-repsol-2.jpg 480w, https:\/\/bxrepsol.s3.eu-west-1.amazonaws.com\/static\/2022\/08\/30043254\/nsr500-repsol-2.jpg 600w, https:\/\/bxrepsol.s3.eu-west-1.amazonaws.com\/static\/2022\/08\/30043254\/nsr500-repsol-2.jpg 900w, https:\/\/bxrepsol.s3.eu-west-1.amazonaws.com\/static\/2022\/08\/30043254\/nsr500-repsol-2.jpg 1280w\" data-src=\"https:\/\/bxrepsol.s3.eu-west-1.amazonaws.com\/static\/2022\/08\/30043254\/nsr500-repsol-2.jpg\" \/><\/picture>\n<noscript><img decoding=\"async\" src=\"https:\/\/bxrepsol.s3.eu-west-1.amazonaws.com\/static\/2022\/08\/30043254\/nsr500-repsol-2.jpg\" alt=\"chasis nsr500\"><\/noscript><figcaption>chasis nsr500<\/figcaption><\/figure>\n<table style=\"color: #fff; background-color: #000; width: 100%;\">\n<tbody>\n<tr style=\"text-align: center;\">\n<td style=\"color: #fff; background-color: #000; padding-left: 1em;\" width=\"50%;\">NSR 5000 engine 1987<\/td>\n<td width=\"50%\"><\/td>\n<\/tr>\n<tr>\n<td style=\"padding-left: 1em;\" width=\"50%\">Displacement<\/td>\n<td style=\"color: #000; background-color: #fff; padding-left: 1em;\" width=\"50%\">499cc<\/td>\n<\/tr>\n<tr>\n<td style=\"padding-left: 1em;\" width=\"50%\">Engine type<\/td>\n<td style=\"color: #000; background-color: #fff; padding-left: 1em;\" width=\"50%\">2-stroke V4 at 112\u00b0<\/td>\n<\/tr>\n<tr>\n<td style=\"padding-left: 1em;\" width=\"50%\">Power<\/td>\n<td style=\"color: #000; background-color: #fff; padding-left: 1em;\" width=\"50%\">156\u00a0hp at 13\u00a0000\u00a0rpm<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>In the year 1989, the Honda NSR500 was the pinnacle of acceleration. Thanks to its reinforced chassis and a special swingarm that accommodated the expansion chambers in the exhausts, the boost in performance was so great that no other motorcycle could match its acceleration rate or velocity. However, the frame was unstable and difficult to control. On the tracks, this beast could surpass speeds of 310\u00a0km\/h, and the engineers increasingly turned their attention to ways in which the bike could be made more manageable without compromising its power. With its sheer force, this bike managed to place Eddie Lawson at the top of the competition in 1989.<\/p>\n<table style=\"color: #fff; background-color: #000; width: 100%;\">\n<tbody>\n<tr style=\"text-align: center;\">\n<td style=\"color: #fff; background-color: #000; padding-left: 1em;\" width=\"50%;\">NSR 5000 engine 1989<\/td>\n<td width=\"50%\"><\/td>\n<\/tr>\n<tr>\n<td style=\"padding-left: 1em;\" width=\"50%\">Displacement<\/td>\n<td style=\"color: #000; background-color: #fff; padding-left: 1em;\" width=\"50%\">499cc<\/td>\n<\/tr>\n<tr>\n<td style=\"padding-left: 1em;\" width=\"50%\">Engine type<\/td>\n<td style=\"color: #000; background-color: #fff; padding-left: 1em;\" width=\"50%\">2-stroke V4 at 112\u00b0<\/td>\n<\/tr>\n<tr>\n<td style=\"padding-left: 1em;\" width=\"50%\">Power<\/td>\n<td style=\"color: #000; background-color: #fff; padding-left: 1em;\" width=\"50%\">165\u00a0hp at 13\u00a0000\u00a0rpm<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>One of the most drastic changes an engine can undergo is a change in the ignition timing, so the pistons can deliver the power all at once or in a distributed manner. In 1990, Honda decided to take a step in this direction and created an engine that fitted the pistons in sets of two at 180\u00b0 angles. This engine, also known as the &#8216;Screamer&#8217; because of the sound it makes, delivered continuous power making the machine even more difficult to control, if possible. As a trade-off, the bike&#8217;s performance peaked. The main challenge now was finding a rider capable of taming it, but luckily Honda had an Ace up its sleeve that went by the name of Mick Doohan. The Australian rider snagged the third position in the 1990 World Championship with the NSR500, a bike he would become inseparable from in the coming years.<\/p>\n<figure><picture style=\"padding-bottom: 61%; background-image: url('https:\/\/bxrepsol.s3.eu-west-1.amazonaws.com\/static\/2022\/08\/30043255\/00_motor_nsr500-2.jpg');\"> <img decoding=\"async\" src=\"https:\/\/bxrepsol.s3.eu-west-1.amazonaws.com\/static\/2022\/08\/30043255\/00_motor_nsr500-2.jpg\" \/><\/picture>\n<picture style=\"padding-bottom: 61%; background-image: url('https:\/\/bxrepsol.s3.eu-west-1.amazonaws.com\/static\/2022\/08\/30043255\/00_motor_nsr500-2.jpg');\"><img title=\"00_motor_nsr500\" alt=\"detalle motor nsr500\" data-srcset=\"https:\/\/bxrepsol.s3.eu-west-1.amazonaws.com\/static\/2022\/08\/30043255\/00_motor_nsr500-2.jpg 480w, https:\/\/bxrepsol.s3.eu-west-1.amazonaws.com\/static\/2022\/08\/30043255\/00_motor_nsr500-2.jpg 600w, https:\/\/bxrepsol.s3.eu-west-1.amazonaws.com\/static\/2022\/08\/30043255\/00_motor_nsr500-2.jpg 900w, https:\/\/bxrepsol.s3.eu-west-1.amazonaws.com\/static\/2022\/08\/30043255\/00_motor_nsr500-2.jpg 1280w\" data-src=\"https:\/\/bxrepsol.s3.eu-west-1.amazonaws.com\/static\/2022\/08\/30043255\/00_motor_nsr500-2.jpg\" \/><\/picture>\n<noscript><img decoding=\"async\" src=\"https:\/\/bxrepsol.s3.eu-west-1.amazonaws.com\/static\/2022\/08\/30043255\/00_motor_nsr500-2.jpg\" alt=\"detalle motor nsr500\"><\/noscript><figcaption>detalle motor nsr500<\/figcaption><\/figure>\n<table style=\"color: #fff; background-color: #000; width: 100%;\">\n<tbody>\n<tr style=\"text-align: center;\">\n<td style=\"color: #fff; background-color: #000; padding-left: 1em;\" width=\"50%;\">NSR 5000 engine 1990<\/td>\n<td width=\"50%\"><\/td>\n<\/tr>\n<tr>\n<td style=\"padding-left: 1em;\" width=\"50%\">Displacement<\/td>\n<td style=\"color: #000; background-color: #fff; padding-left: 1em;\" width=\"50%\">499cc<\/td>\n<\/tr>\n<tr>\n<td style=\"padding-left: 1em;\" width=\"50%\">Engine type<\/td>\n<td style=\"color: #000; background-color: #fff; padding-left: 1em;\" width=\"50%\">2-stroke V4 at 112\u00b0<\/td>\n<\/tr>\n<tr>\n<td style=\"padding-left: 1em;\" width=\"50%\">Power<\/td>\n<td style=\"color: #000; background-color: #fff; padding-left: 1em;\" width=\"50%\">170\u00a0hp at 13\u00a0000\u00a0rpm<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>When changes in regulation increased the minimum weight to 130\u00a0kg and set limits for the breadth of wheels, it became necessary to make further adjustments to soften the NSR500\u2019s temper. Its powerful engine meant that, in its new design, the bike would swerve when giving it the littlest bit of gas. It was the fastest frame on the grid in terms of peak speed, but it had a harder time accelerating and could not run the curves as smoothly. However, even this could not stop Doohan from coming in second at the 1991 World Championship.<\/p>\n<p>However, the Honda team decided to make it easier to handle, and the engine\u2019s configuration once again underwent a drastic change in 1992. The ignition timing was changed yet again, so that all pistons fired practically simultaneously. This new system, known as &#8216;Big Bang&#8217;, provides the engine with increased resting time between each firing, and gives better traction and less wear to the tyres with only a slight decrease in power. With this new configuration and given the 112\u00b0 angle of the bank of cylinders, the vibrations generated by the simultaneous firing were counteracted, and one of the rotating shafts could be removed since its only purpose was to soften said vibrations.<\/p>\n<p>In 1993, an important technological breakthrough took place when electronic fuel injection was implemented. With two injectors per piston and an ECU which was capable of managing the supply\u2019s optimum functioning. This system made it possible for Sinichi Itoh to become the first pilot that achieved speeds of over 320\u00a0km\/h. In spite of this success, there did not seem to be significant improvements in comparison to traditional carburettors, so the entire system was dismissed.<\/p>\n<table style=\"color: #fff; background-color: #000; width: 100%;\">\n<tbody>\n<tr style=\"text-align: center;\">\n<td style=\"color: #fff; background-color: #000; padding-left: 1em;\" width=\"50%;\">NSR 5000 engine 1993<\/td>\n<td width=\"50%\"><\/td>\n<\/tr>\n<tr>\n<td style=\"padding-left: 1em;\" width=\"50%\">Displacement<\/td>\n<td style=\"color: #000; background-color: #fff; padding-left: 1em;\" width=\"50%\">499cc<\/td>\n<\/tr>\n<tr>\n<td style=\"padding-left: 1em;\" width=\"50%\">Engine type<\/td>\n<td style=\"color: #000; background-color: #fff; padding-left: 1em;\" width=\"50%\">2-stroke V4 at 112\u00b0<\/td>\n<\/tr>\n<tr>\n<td style=\"padding-left: 1em;\" width=\"50%\">Power<\/td>\n<td style=\"color: #000; background-color: #fff; padding-left: 1em;\" width=\"50%\">170\u00a0hp at 12\u00a0500\u00a0rpm<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Even though the 1994 season saw no major changes, towards the end a water injection system was incorporated to the exhausts which improved performance in the mid-range of revolutions. An extra 10\u00a0hp were achieved in the range between 6000 and 10\u00a0000\u00a0rpm when the temperature of the combustion chambers was modified. Doohan decided against this improvement and instead chose a more conventional engine, since the bike was already sufficiently hard to handle. Doohan finally managed to win the World Championship on this machine, making it evident that the NSR500 development was reaching its peak.<\/p>\n<p>In 1995, carburettors over 39\u00a0mm were installed, significantly improving performance. Thanks to this tweak, and a stronger than ever Honda team, Doohan won his first two World Championships for the Repsol Honda Team in 1995 and 1996.<\/p>\n<table style=\"color: #fff; background-color: #000; width: 100%;\">\n<tbody>\n<tr style=\"text-align: center;\">\n<td style=\"color: #fff; background-color: #000; padding-left: 1em;\" width=\"50%;\">NSR 5000 engine 1996<\/td>\n<td width=\"50%\"><\/td>\n<\/tr>\n<tr>\n<td style=\"padding-left: 1em;\" width=\"50%\">Displacement<\/td>\n<td style=\"color: #000; background-color: #fff; padding-left: 1em;\" width=\"50%\">499cc<\/td>\n<\/tr>\n<tr>\n<td style=\"padding-left: 1em;\" width=\"50%\">Engine type<\/td>\n<td style=\"color: #000; background-color: #fff; padding-left: 1em;\" width=\"50%\">2-stroke V4 at 112\u00b0<\/td>\n<\/tr>\n<tr>\n<td style=\"padding-left: 1em;\" width=\"50%\">Power<\/td>\n<td style=\"color: #000; background-color: #fff; padding-left: 1em;\" width=\"50%\">190\u00a0hp at 12\u00a0000\u00a0rpm<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>The Screamer engine made its way back to Doohan&#8217;s bike in 1997.
