Triumph T140 Tracker #38

The Triumph T140 Tracker #38 is a 1979 Triumph tracker reimagined by Argentina's Herencia Custom Garage, pairing a vintage Bonneville silhouette with Ducati front suspension, Ohlins rear damping, and a hand-shaped aluminium tank in a build that keeps the classic Triumph character while sharpening every ride input.

The Concept

Federico and German at Herencia Custom Garage received a straightforward brief from the client: keep the vintage Triumph look, upgrade every part that touches the road. Project #38 is the response. The 1979 T140 platform was chosen for its silhouette and its parts-catalogue accessibility, then rebuilt around modern suspension, braking, and chassis geometry. The pair works with the synchronization of a team that has produced dozens of scramblers and street trackers together, and their signature is legible across the entire build.

The Build

An old Webco fiberglass tank was copied in aluminium alloy, shaped by hand to preserve the era's silhouette in a modern material. The front end was replaced with a Ducati fork paired with a Harley front hub, joined by a Ducati disc brake through a CNC-machined Ducati-to-Harley adapter fabricated in-house. Rear motor support brackets were also custom CNC-machined. The rear suspension was upgraded to Ohlins for controlled damping on rough surfaces. A CB750 rear hub and caliper were adapted at the back with a 2-inch swingarm correction, both simplifying the visual line and improving handling. The front brake master cylinder was hidden under the tank to make room for Tomaselli Matador brake and clutch levers, keeping the cockpit clean. The exhaust system is handbuilt by Herencia in their signature style, tuned as much for sound as for flow.

Performance

The Triumph T140 twin retains its vertical character while riding on a chassis that has been quietly transformed. The Ducati front suspension paired with the Ohlins rear delivers a compliant, planted feel across broken surfaces, and the CNC-machined adapters and brackets keep everything geometrically consistent. The 2-inch swingarm correction combined with the lighter CB750 rear hub gives the bike sharper turn-in and reduced unsprung weight. The Tomaselli levers, hidden master cylinder, and Herencia handbuilt exhaust complete a build where every touchpoint has been considered. The result is a period-correct visual read with contemporary ride manners.
