Race-Ready Style. Street-Strong Sound.

Blacked-out café racers are more than a trend—they’re a lifestyle. And if you’re crafting a dark-themed build with real street bite, the Roybull Grumbler Black Exhaust is the perfect finishing touch for your Continental GT 650.

Engineered for style, sound, and speed, this performance exhaust offers stealthy aesthetics, a deep-throttle growl, and noticeable power gains—all while preserving the spirit of the GT’s retro-racer legacy.

Whether you’re racing to a café meetup or gunning it down the expressway, the Grumbler Black adds serious edge to both your look and performance.

Matte Black Ceramic Finish – Built to Match Aggressive Builds

The Grumbler Black is finished with a matte black ceramic coating that pairs flawlessly with blackout GT builds. Whether you’re running black crash guards, powder-coated wheels, or custom tank wraps, this exhaust blends in beautifully while still making a bold statement.

The ceramic coating is scratch-resistant, heat-tolerant, and fade-proof, so it holds its style even in demanding city and highway conditions. Plus, it’s low-maintenance and easy to clean, perfect for riders who love riding more than polishing.

Performance-Tuned Sound with Street Attitude

Unlike loud, unrefined aftermarket pipes, the Grumbler Black is acoustically tuned to complement the GT 650’s 648cc parallel-twin engine. It produces a deep, tight exhaust note—aggressive when you want it, mellow when you cruise.

There’s no echo or distortion—just a rich, bass-forward growl that feels natural to the GT’s race-inspired character. Ideal for riders who want more presence without breaking local noise rules.

Durability Built for High-Revs and Heat

The GT 650 is meant to be ridden hard, and the Grumbler Black is designed to keep up. Constructed from high-grade steel with reinforced welds, it’s ready for long rides, high-revving sprints, and hot summer days.

The ceramic finish further protects against thermal stress, preventing cracking, warping, or discoloration even when the revs climb or traffic slows. Whether you’re doing city miles or mountain runs, the Grumbler Black performs like a pro.

Performance Boosts You Can Feel

The Grumbler isn’t just about sound—it delivers functional improvements to your GT 650’s riding dynamics. Its free-flowing design reduces back pressure, improving:

• Throttle responsiveness

• Low-end torque

• Combustion efficiency

• Overall ride smoothness

These upgrades make a real difference during quick overtakes, gear pulls, and highway cruising, all without needing ECU remapping or air filter changes.

Seamless, Bolt-On GT Compatibility

Designed specifically for the Continental GT 650, the Roybull Grumbler Black offers a 100% plug-and-play fit. No cutting, bending, welding, or special brackets are needed.

You can install it yourself in 20–30 minutes using standard tools. It fits the bike’s stock mounting points perfectly and clears rear-set foot pegs without modification.
