TWR XR250 Motard BAJA MD30 Direct Ignition Reinforced Plug Cap

Spark plugs are an important ignition system that triggers the combustion cycle by sparking the air-fuel mixture filling the combustion chamber, but with current off-road motorcycles, manufacturers are limited in their development and installation costs. The commonly known DI "Direct Ignition" system, which is equipped on closed course racers that have maximized engine performance, is installed on Honda's traditional air-cooled RFVC engine to ensure the reliability of the ignition system while improving fuel efficiency and torque. This is a reinforced part aimed at further increasing the power of the engine. With this system, the high-voltage ignition current generated by the integrated ignition coil is transmitted straight to the plug and sparked, thereby addressing the structural problems that were the weaknesses of the genuine coil (i.e., dealing with high engine speeds). In order to solve problems such as poor contact due to leaks, radio noise caused by sparks, etc.), we installed it on the XR250 (MD30) and XR250R (ME08) and monitored the operating status over a long period of time, ensuring that even the spark plug specified by the original manufacturer is always suitable. We have prepared an enhanced direct ignition system that provides stable ignition performance and even higher combustion efficiency. ◆The feature of direct ignition is that it does not require the conventional plug cord, so there is no distance from the ignition coil to the plug (there is no electrical resistance), so the loss of generated voltage can be kept to the necessary minimum, and it is different from conventional ignition. Compared to other systems, combustion efficiency is significantly improved, and stronger torque is also obtained, resulting in significantly better fuel efficiency. *Resistance value of genuine plug cap Primary side resistance value: 0.1~0.3Ω ・Secondary side resistance value: 7.2~11kΩ ★Resistance value of direct ignition reinforced plug cap Primary side resistance value: 0.07~0 .1Ω ・Secondary side resistance value: 4.6 to 6.8kΩ ◎ Improved combustion efficiency minimizes the adhesion of non-combustible substances to the piston head, and compares combustion conditions using genuine standard plugs [Left: Genuine, Right: If you take a look at [Reinforced Parts], you will understand the effect of combustion efficiency. ★Currently one of the few standard customizations that can easily strengthen the ignition, this ignition system tune-up has been adopted by many successive XR series owners and bike shops and has been very popular. This is a long-selling part. ★Applicable car model: XR250/Motard/BAJA (Model: MD30 Compatible with all model years) * Simultaneously exhibited [XR250 series AI system cancellation set] ≪XR250 Motard BAJA genuine carburetor reinforcement set≫ ・[Reinforced chain adjuster L side ]・Please also take a look at “Air Cleaner BOX Carbon Style Decal Set”・<>・[New XR250 Motard BAJA Kick Starter Full Parts Set]. This is a safe and reliable JAN/EAN code registered part that is a standard product established by JIS.

★TWR Original Reinforced Parts Series This system transmits the high voltage ignition current generated by the ignition coil directly to the plug and causes a spark, thereby addressing various structural issues that were the weak points of the ignition coil. In order to solve problems such as difficulty in responding to high engine speeds, poor contact due to leaks, generation of radio noise due to sparks, etc., we conducted implementation tests to monitor and review the operating conditions of the XR250 (MD30) and XR250R (ME08). We offer an enhanced direct ignition system to ensure proper operation at all times. ◆You can choose between two colors: red and black as shown in the image. ★The feature of direct ignition is that it does not require a conventional plug cord, so there is no distance from the ignition coil to the plug (there is no electrical resistance), so it is possible to minimize the loss of generated voltage, making it possible to reduce the distance between the ignition coil and the plug. Compared to other systems, combustion efficiency is significantly improved, and stronger torque is also obtained, resulting in significantly better fuel efficiency. ★In order to maximize this performance, we have paid careful attention to the materials we use, and the cable that connects the direct ignition to the bike is made of heat-resistant, oxygen-free copper with a purity of 99.95% or higher that does not contain any oxides. A cable (commonly known as OFC cable) is used to reduce resistance and distortion, reducing transmission loss. In addition, in order to prevent the OFC cable from deteriorating due to the engine heat generation temperature, we use a corrugated tube without slits (using flame-retardant material) dedicated to super heat resistance, and the inside of the tip is waterproof and sealed with heat-resistant silicone resin to prevent leaks. By applying the processing, we aim to increase the durability of the entire system. ◎In my blog titled "HONDA XR250 Powered by TWR", I have included images of the combustion state of the engine head combustion chamber and piston head after a certain period of implementation testing on an XR250 (MD30) equipped with an actually produced prototype. We would like to introduce you to them, so please take a look.・※ Simultaneously exhibited [XR250 Series AI System Cancellation Set] ≪XR250 Motard BAJA Genuine Carburetor Reinforcement Set≫ ・[Reinforced Chain Adjuster L Side] ・“Air Cleaner BOX Carbon Style Decal Set” ≪XR250 Motard BAJA Racer Front Sprocket Please also take a look at the Cover Set≫・[New XR250 Motard BAJA Kick Starter Full Parts Set].
