Triumph Street Triple 765 RS 2017-2020

The street triple 765 RS represents one of Triumph’s most exhilarating naked sports bikes, and fitting the right performance exhaust system can transform both its sound and performance characteristics. Our Quill Performance Exhaust has been specifically engineered for the Triumph Street Triple 765 RS 2017-2020 models, delivering race-proven quality and exceptional value for riders who demand the very best from their machine.

About the Street Triple 765 RS Exhaust System

This premium motorbike exhaust is designed exclusively for the Triumph Street Triple 765 RS manufactured between 2017 and 2020. Unlike many aftermarket exhaust options that compromise on fitment or quality, our system has been precision-engineered to integrate seamlessly with your bike’s existing architecture. We manufacture our exhausts for this model at race height rather than the lower standard level, giving your Street Triple that aggressive, track-inspired stance whilst maintaining optimal ground clearance for spirited riding.

Each exhaust system comes complete with everything you need for a straightforward installation. You’ll receive one stainless steel 304 CNC mandrel bent link pipe, crafted to exacting tolerances for perfect fitment. The package also includes one stainless exhaust strap and one exhaust strap rubber, ensuring your new exhaust is mounted securely and vibration-free. This exhaust is manufactured to fit directly to the standard OEM downpipes, eliminating the need for additional modifications or expensive custom fabrication work.

Why Choose Quill Performance for Your Street Triple 765

When selecting an aftermarket exhaust for your street triple 765, quality of materials and precision engineering should be your top priorities. Our exhausts are constructed from premium grade 304 stainless steel, chosen specifically for its exceptional durability, corrosion resistance, and ability to withstand the extreme temperatures generated by high-performance engines. The mandrel bending process we employ ensures consistent internal diameter throughout the entire length of the pipe, maximising exhaust gas flow and delivering measurable performance gains.

The race height positioning of our Street Triple exhaust system offers multiple advantages. Firstly, it provides improved cornering clearance compared to lower-mounted alternatives, allowing you to lean further into corners with confidence. Secondly, the higher position contributes to better mass centralisation, subtly enhancing the bike’s already impressive handling characteristics. Finally, the race height fitment gives your Street Triple an unmistakably purposeful appearance that complements its aggressive styling perfectly.

Our commitment to British manufacturing means every exhaust is produced to the highest standards right here in the UK. This allows us to maintain rigorous quality control throughout the production process and respond quickly to customer feedback. We’ve been crafting performance exhausts for a wide range of Triumph motorcycles, including systems for the Triumph Speed Triple 955i 2000 – 2004, demonstrating our extensive experience with the Triumph marque.

Performance Benefits of Upgrading Your Street Triple 765 Exhaust

Installing a Quill Performance Exhaust on your street triple 765 delivers tangible improvements across multiple performance parameters. The optimised flow characteristics reduce back pressure in the exhaust system, allowing the engine to expel spent gases more efficiently. This translates to improved throttle response, particularly noticeable in the mid-range where the Street Triple’s triple cylinder engine already excels.

Riders typically report a more eager, responsive feel when rolling on the throttle, with the bike feeling more willing to rev freely throughout the range.

Beyond performance metrics, the sound transformation is perhaps the most immediately noticeable benefit. The standard OEM exhaust on the Street Triple 765 RS, whilst adequate, tends to muffle the characterful tone of Triumph’s 765cc triple cylinder engine. Our performance exhaust unleashes that distinctive three-cylinder howl, delivering a deep, purposeful note that sounds spectacular both at idle and when extended towards the redline. It’s loud enough to make your presence known and thoroughly enjoyable, yet civilised enough for everyday riding.

Weight reduction is another significant advantage. Aftermarket performance exhausts typically weigh considerably less than the standard OEM components they replace. Reducing weight from the rear of the motorcycle improves the power-to-weight ratio and contributes to more nimble handling characteristics. For track day enthusiasts and spirited road riders alike, every kilogram saved makes a noticeable difference to how the bike feels and responds.

Installation and Fitment for the Street Triple 765 RS

One of the key advantages of our exhaust system is the straightforward installation process. Because the system is designed to connect directly to your standard OEM downpipes, there’s no need for cutting, welding, or specialist tools. Mechanically competent owners can typically complete the installation in under an hour using basic hand tools. The CNC mandrel bent link pipe ensures precise alignment with existing mounting points, eliminating the frustration of poor-fitting aftermarket components.

The included stainless exhaust strap and rubber mounting ensure the exhaust is held securely in position whilst allowing for the natural thermal expansion that occurs during operation. This attention to mounting detail prevents unwanted vibration and ensures the exhaust maintains proper alignment over thousands of miles of use. We recommend applying a small amount of high-temperature copper grease to the joint between the link pipe and downpipe before assembly to facilitate future removal and prevent seizing.

For riders looking to upgrade other Triumph models, we offer an extensive range including exhausts for the Triumph Tiger 1200 Explorer, demonstrating our comprehensive coverage across Triumph’s diverse model lineup.

Maintenance and Long-Term Durability

The 304-grade stainless steel construction ensures your exhaust will maintain its appearance and structural integrity for many years. Unlike mild steel exhausts that quickly succumb to corrosion, particularly in the UK’s damp climate, stainless steel resists rust and oxidation exceptionally well. Occasional cleaning with appropriate stainless steel cleaner will keep the finish looking pristine, though many riders appreciate the subtle patina that develops over time, adding character to their machine.

Regular inspection of the mounting hardware and joints should form part of your routine maintenance schedule. Check that the exhaust strap remains tight and that the rubber mounting shows no signs of deterioration. The simplicity of the system means there are fewer components to fail compared to more complex full system replacements.
