Custom Triumph Bonneville “The Leonard T120”: Dark Presence, Personal Legacy

PUBLISHED 16.05.2026

The streets of London have a new predator. Our latest custom Triumph Bonneville has officially rolled out of the Triumph West London workshop, marking a significant milestone for the dealership. The Leonard T120 represents the first completed motorcycle since the renowned Charlie Stockwell took the helm of custom bike operations for the LIND group’s West London outpost.

Based on the signature "Stockwell Bonneville" aesthetic, this T120 is a masterclass in aggressive minimalism, proving that the classic British twin still has a dark side worth exploring.

True to the Stockwell DNA, The Leonard is dark, aggressive, and chopped. The silhouette has been tightened and lowered, stripping away the traditional "gentleman’s express" vibe of the standard T120 in favour of something far more urban and menacing.

The standout feature is undoubtedly the short, stubby Zard exhaust system. This free-flowing, fully unrestricted setup does more than just slim down the bike’s profile; it unleashes a deep, visceral growl from the 1200cc engine while providing a noticeable increase in both power and torque.

To match the "go-anywhere" attitude of the build, the team opted for Heidenau K60 tyres. These tyres bridge the gap between form and function, providing the rugged, knobbly look essential for a custom scrambler/bobber hybrid while maintaining reliable grip and longevity for everyday road use in all weather conditions.

The bike's handling has been equally transformed to match its aggressive stance. The suspension has been significantly upgraded, featuring Fox Racing rear shocks for superior damping and a more planted feel. Up front, the forks have been reworked with Öhlins internals, ensuring that The Leonard doesn't just look like a performance machine, but also handles the city streets and weekend escapes with precision and poise.
 

While The Leonard T120 is undeniably dark and aggressive in its execution, it carries a more personal story beneath the surface.

A bespoke reworked saddle introduces subtle Pillar Box Red stitching that breaks through the monochrome palette, while hand-finished custom logos in gold and red add warmth and individuality across the tank and side panels. These details are restrained, but deeply intentional.

Most importantly, the bike carries the name “The Leonard T120” as a tribute to the owner’s dear father, transforming the build from a high-performance custom into something far more meaningful.
