Our first love is the Manx, but we have been manufacturing replica G50 and 7R parts since 1991, before we acquired the Manx business, indeed we learnt the skills required to machine complex castings to the tight tolerances required for racing engines on G50 crankcases and camboxes. We source our castings only from foundries that specialise in motor sport components. Our engineering expertise, coupled with our investment in CNC machinery, enable us to produce the most accurate, best quality components on the market.

Many people are unaware that when Bob Heath was in record-breaking form throughout the latter 90’s his engines were built incorporating our major components.

We have continually expanded our AJS and Matchless components so that we can now offer a complete range of replacement engine parts, complete engines to 1962 specifications, and complete machines with either a standard AMC replica or our own replica Seeley rolling chassis.

In addition, we now offer a range of tuned engines, from ultra-short stroke 7R's through to the 4 valve DOHC G50.
