The exhaust takes inspiration from the classic British “trumpet” silencers used on scramblers and sports motorcycles in the 1950s. It is defined by its long, elegant expanding shape and narrow outlet, which gave the single and twin-cylinder motorcycles of the era their distinctive raw sound.

Unlike the original chrome versions, this model is manufactured from brushed stainless steel, offering:

• higher mechanical durability
• a long-lasting surface finish without the need for polishing

The body of the exhaust features a clean, minimalist design without unnecessary transitions. Thanks to its progressive conical expansion, it delivers quick engine response, better exhaust flow and naturally fuller character throughout the midrange.

The sound delivers a deeper, richer tone typical of British scramblers built during the 1950s.

• Stainless steel link pipe extension with lambda sensor mount
• 4kg weight reduction compared to the stock exhaust
• Does not negatively affect the air-fuel mixture
• Brass Sharon / Gas & Oil Exhaust badge
• Integrated DB killer / spark arrestor included. The sound is more refined and less aggressive than many aftermarket exhausts, however the exhaust is NOT certified for road use within the European Union.
• Spark arrestor included, allowing use in regions such as California and Australia, where fire protection regulations are taken seriously..

The exhaust has been tested together with the motorcycle on a dyno. The graph confirms optimal exhaust gas flow and guarantees safe engine operation.

For increased performance, we also recommend combining the exhaust with our Gas & Oil BOOSTBOX. This combination fully transforms the motorcycle character and brings the engine truly to life.
