Triumph Scrambler 400X: Custom Build Saves 15 Kilos, Parts Available Individually

• Custom build by Martin Motorcycle Company from Bristol based on the Triumph Scrambler 400X
• Öhlins shock absorber and handmade stainless steel exhaust system, plus around 15 kilograms less weight
• Limited series planned for around 12,000 pounds (approximately 13,900 euros / 15,700 US dollars), parts also available separately

The Triumph Scrambler 400X is one of the best-selling small single-cylinder models from the brand and has built a loyal following in several markets. This is precisely where a project from England comes in: Martin Motorcycle Company, a Triumph specialist based in Bristol, has developed the compact Scrambler in two directions — chassis and engine on one hand, styling on the other. The build follows a so-called OEM-plus approach, where the character of the production motorcycle is preserved while details, stance, and components are deliberately sharpened.

Who Is Behind the Triumph Scrambler 400X Custom Build?

Behind the project is Martin Motorcycle Company from Bristol, run by Alex Martin. The business positions itself as an independent Triumph specialist with a workshop, custom department, and parts trade. The motorcycle shown was initially built as a commission for a customer. The company now plans a limited production run and offers the individual components for sale, so owners can upgrade their own 400 accordingly. The build was publicly presented at the Bike Shed Show in London, where the workshop showcased the bike as its latest custom build.

What Changes Were Made to the Chassis and Engine?

At the heart of the technical overhaul are an Öhlins shock absorber and a handmade stainless steel exhaust system. The rear shock from the Swedish brand is a new design with a custom-tuned spring, priced at 980 pounds (approximately 1,135 euros / 1,285 US dollars).

The exhaust system costs 650 pounds (approximately 750 euros / 850 US dollars) and is said to save around 15 kilograms (about 33 lbs) over the stock part. Martin says the original component was surprisingly heavy when removed, made from basic stainless steel with a large catalytic converter the size of a shoebox. The new system currently features a Vance & Hines silencer, though a proprietary silencer is reportedly in development. It is tuned to work with the stock fuel injection and retains the connections for both factory lambda sensors, but omits the stock catalytic converter, which is said to produce a fuller sound. A removable baffle insert allows the volume to be increased further, according to the workshop. The motorcycle has not yet been on a dynamometer. Together with a DNA air filter, the system is said to deliver a few extra horsepower.

What Wheels, Tires, and Brakes Are Fitted?

For wheels and brakes, the workshop draws on components from various suppliers. Fitted among other things is a floating brake disc from Free Spirits of Italy. Also included are Bridgestone AX41 tires and spoke wheels from VMX Racing, a Finnish manufacturer specializing in supermoto and motocross wheels.

What Styling Parts Does Martin Motorcycle Company Use?

On the styling side, the build features a selection of carefully chosen accessories while maintaining a factory-like appearance. Components include a Renthal Fatbar handlebar conversion, radiator and headlight guards from Evotech, and modified motocross footpegs. The outer fork stanchions have been black anodized instead of the stock gold finish, complemented by a black-and-gold drive chain. A custom paint job and a reupholstered seat round off the appearance. The workshop describes the result as understated and purposeful, built with the aim of looking as though the motorcycle could have left the factory this way.

How Much Does the Custom Triumph Scrambler 400X Cost?

The planned limited series is set to be offered for around 12,000 pounds (approximately 13,900 euros / 15,700 US dollars), each including a donor vehicle. For comparison, the stock Scrambler 400X is listed in Germany at a price starting from approximately 6,915 euros (approximately 7,830 US dollars). Those who do not want the complete motorcycle can also purchase the components individually, according to Martin.

What Characterizes the Stock Triumph Scrambler 400X?

The Triumph Scrambler 400X is an A2 license-compliant single-cylinder model developed jointly with partner Bajaj Auto and manufactured in India. The liquid-cooled 398 cc engine produces 40 hp (29 kW) at 8,000 rpm and delivers 37.5 Nm (approximately 27.7 lb-ft) of torque at 6,500 rpm. The wet weight is 179 kilograms (about 395 lbs), the seat height is 835 millimeters, and the tank holds 13 liters. Standard equipment includes switchable dual-channel ABS and a 19-inch front wheel. The widespread popularity of the model has led to a growing custom scene developing around the small Triumph, into which the Bristol build fits.
