ARROW THUNDER 51020AKN full exhaust system in black aluminum with stainless steel headers for HONDA CB 125 R NEO SPORTS CAFÉ 24-26
This is the THUNDER system with a carbon end cap, featuring a black aluminum model with a stainless steel link pipe and headers.
Silencers are increasingly being developed in smaller sizes and mounted in unusual positions. For this reason, Arrow has developed the Street Thunder exhaust line, combining design and cutting-edge technology. Available in stainless steel or carbon fiber, these silencers feature a diamond shape inspired by the Off-Road program.
To compensate for the reduced volume, Arrow uses high-quality, track-tested sound-absorbing and heat-insulating materials. The Street Thunder line is available in homologated versions and in materials such as titanium, aluminum, and carbon fiber, offering superior performance and a striking aesthetic.

What materials is it made of?
The silencer body is made of aluminum, which allows the exhaust to be much lighter compared to a steel one. This material also dissipates heat more effectively, which contributes to improved performance. Aluminum is highly corrosion-resistant and has a glossy appearance. In addition, the exhaust features a black finish, which is achieved through a ceramic-based painting process, resulting in a more aggressive look.
The header is made of high-quality austenitic stainless steel, which offers high corrosion resistance, improved high-temperature resistance properties, and perfected formability.
The durability of the materials used for its development is track-tested to ensure optimal road performance.

Frequently Asked Questions
¿Cómo sé si este escape es compatible con mi moto?
El título y la descripción indican la marca, el modelo y los años de la moto para los que está fabricado. Si tienes dudas, escríbenos por WhatsApp al +34 614 30 74 60 con tu modelo y año, y te confirmamos la compatibilidad antes de comprar.
¿Qué diferencia hay entre un slip-on y una línea completa?
El slip-on (tramo final) sustituye el silenciador y el semicolector, y se monta sobre los colectores de serie. La línea completa sustituye todo el escape desde el motor, colectores incluidos, por lo que el cambio de sonido, rendimiento y peso es mayor.
¿Es difícil montar el escape?
Nuestros escapes incluyen el kit de montaje necesario. Un slip-on se puede montar en casa con herramienta básica; para una línea completa recomendamos hacerlo en un taller.
¿Hay que reprogramar la centralita?
Con un slip-on normalmente no es necesario. Con una línea completa, o si se quita el catalizador, es recomendable ajustar el mapa de la centralita en un taller para sacar el máximo rendimiento.
¿Qué es el DB-Killer y para qué sirve?
Es una pieza extraíble que va dentro del silenciador y reduce el nivel de ruido. Con el DB-Killer puesto el escape suena más discreto; sin él, suena más fuerte y racing.
Are the exhausts approved?
We have both approved and non-approved models in stock. Approved models are clearly indicated in the description. If nothing is mentioned, it is not approved.
Do they pass the MOT?
Approved models pass the MOT, as long as they have the db killer and catalytic converter installed.
Will I be fined if it is not approved?
Almost all of our non-homologated models include removable DB killers. If the DB killer is installed, fines are not usually incurred.
