Description

Since starting production of their own motorcycles in the mid 1950’s Honda have grown to be one of the largest two-wheel manufacturers in the world. Soichiro Honda always had a passion for motorsport so it was inevitable that before long they would race bikes in Grand Prix and the iconic Isle of Man TT with Mike Hailwood securing their first senior TT win in 1966. The formation of Honda Racing Corporation (HRC) in 1982 saw them debut their first two-stroke race bike the NS500 which went on to win the Grand Prix world championship in 1984 and since then Honda has been a dominant force in Grand Prix racing winning numerous championships and heads the number of wins at the TT.  From the mid 1990’s Scorpion have been producing performance exhausts for a huge range of Honda Motorcycles whilst passing on our knowledge and experience gained from working with the Ron Haslam Race School and numerous race teams over the years.

  • Designed, developed, and manufactured in Derbyshire, UK since 1992

Full System:

Our expert technicians have developed a complete high-performance exhaust system specifically for the Honda Monkey Euro 5+ model. Explore the specifications and available options below!

Why choose a full system? For maximum performance and sound — our full exhaust systems deliver everything in one complete package — the perfect blend of slip-on and header technology, engineered for when those two options just won’t cut it on their own. Each system includes a high-flow silencer, race headers, and de-cat pipework, all designed to eliminate restrictions, let your engine breathe freely, and unlock the full potential of your machine.

The result is more power, sharper throttle response, significant weight reduction, and that raw, aggressive sound — all with our signature Scorpion tone. Our high-flow design removes the factory’s restrictive filters which cause excessive back pressure, while the smooth, CNC mandrel-bent headers help exhaust gases escape quickly and efficiently — just like on a race bike, thanks to our track-to-road technology.

This is our ultimate “full firepower” option for riders who demand the best in performance and sound. (For motorsport use only.)

We cannot guarantee that fitting the lambda catalyst will prevent the EML from illuminating in all circumstances, however the light does not effect riding modes / functionality.

Silencer Style:

Red Power: Designed with a shorter, retro-inspired compact appearance, it delivers a bold, guttural soundtrack that amplifies your bike’s personality.

Want to hear our exhausts in action? Watch our official Scorpion dyno-test video and experience the sound and performance for yourself! See how our systems can elevate your riding experience. Head over to @scorpionexhaustsyt on YouTube or check out the video section below on this page.

Silencer Finishes:

Brushed Stainless: Crafted from premium T304 stainless steel and meticulously hand-finished, this piece boasts a modern, textured appearance that exudes quality and durability.

Black Ceramic: The matte black finish provides a stealthy, modern look. The silencers undergo a specialised coating process, ensuring a durable and flawless finish.

Titanium: Extremely hard-wearing and lightweight, titanium offers an unmistakable colour palette with a smooth satin surface.

Installation:

Installing your new exhaust couldn’t be easier! Every system comes with detailed instructions — available both in print and as downloadable PDFs — and for select models, we also offer video installation guides on our @scorpiontechnical YouTube channel. Engineered for a perfect fit, our exhausts require no cutting of OEM components or ECU remapping. Simply install, hit the road, and enjoy!

Crafted from premium T304 stainless steel, designed to endure the harshest of conditions. CNC Mandrel bent construction provides unmatched gas-flow, enhancing throttle response and boosting BHP.
