About ASE Custom Motorcycles
ASE Custom Motorcycles is Andy Steward's workshop in Balsall Common near Coventry, in the heart of the West Midlands. Andy studied Motorsport Engineering & Design and then spent around eleven years as a design engineer and project manager for Jaguar Land Rover and Aston Martin. After a break to travel and work abroad, he went self-employed with one goal: to offer design, engineering and hands-on craftsmanship for motorcycles under one roof. The workshop builds café racers, scramblers, trackers, bobbers and resto-mods, starting from a new bike, a classic or a blank sheet. It has its own metal shop with TIG and MIG welding and tube bending, plus 3D scanning, CAD, 3D printing and glass-fibre and carbon lay-up. Stainless steel exhausts are made in-house, and wiring looms are rebuilt around motogadget control units and Rebelmoto switchgear. Seats, paint, powder coating, vapour blasting, ultrasonic carburettor cleaning and tyre fitting are part of the service too, and ASE sells parts for your own build through its web shop. Well-known builds include the café racer “Alpha”, based on a Yamaha XV920 Virago and shown at the Bike Shed Show in London, a BMW K100 café racer in Nardo grey, a scrambler built from a Kawasaki KLR 650 and a Husqvarna 701 supermoto with a hand-made aluminium tank (Bike Shed Show 2022). Alongside customer builds, ASE develops prototypes, small-batch parts and show bikes for manufacturers, and built two Ducati 916s for Prosperity Racing that Sam West and Davey Todd raced at the 2025 Isle of Man Classic TT. Work is charged at an hourly workshop rate plus parts. According to the workshop, new projects currently have a waiting list of around 20 to 24 months (as of November 2026); a consultation can be booked in the meantime. First contact preferably by email, workshop visits by appointment only.
