This 2006 Triumph Bonneville was rebuilt as a tracker by Mule Motorcycles with custom bodywork, 19″ wire-spoke wheels, an MV Agusta F4 front end, a custom two-into-one exhaust, a stainless-steel handlebar, an Acewell gauge, and Öhlins shocks. Its parallel-twin was fitted with a 904cc big-bore kit, aftermarket camshafts and intake manifolds, larger intake valves, and Keihin FCR39 carburetors. Additional equipment includes a five-speed gearbox, a side stand, a Sportster headlight, Shinko tires, and a selection of Mule components. “Colonel Mustard” was acquired by the seller in July 2026 and is now offered at no reserve with service records and a clean California title in the seller’s name.

The custom tracker bodywork has been finished in Pearl White with black center accents, and further modifications include a Harley-Davidson Sportster headlight, a Joker Machine headlight mount, a black vinyl solo seat, and the turn signals.

Black-finished 19″ SunRims alloy rims are laced with stainless-steel spokes and nipples to Mule lightweight alloy hubs and were mounted with Shinko 130/90 front and 140/90 rear tires in July 2026. the bike also features an MV Agusta F4 inverted fork with a single disc brake up front as well as dual Öhlins shocks out back. Additional work in July 2026 included lubricating the drive chain and flushing the brake fluid.

The Mule stainless-steel handlebar carries a Nissin radial master cylinder and fronts an Acewell digital dashboard with a bar-graph tachometer, a speedometer, and a coolant temperature gauge. Total mileage is unknown.

The air-cooled 865cc DOHC parallel-twin was overhauled with a 904cc big-bore kit, cylinder head porting, larger intake valves, a custom ignition map, and aftermarket camshafts, intake manifolds, and Keihin FCR39 carburetors. The custom two-into-one upswept exhaust system was made using stainless-steel and a shortened DMC muffler.

Power is delivered to the rear wheel through a sequential five speed transmission and a gold drive chain rolling on a black sprocket.
