BDK magnesium throttles for2, 3 and 4 cylinder engines

If you admire engineering, these are a thing of beauty.

BDK race engineering are fanatical two-stroke experts that practice what they preach, racing anything from TZs, to VFR400s to a Jawa 350 V4 two-stroke in classic events, including Chimay and on road circuits in the Czech republic.

They tune, modify and rebuild some of the most incredible machines and every time I pop in I learn something!


They also make parts, like racing generators, and now, the lightest throttles I’ve ever seen.

A magnesium throttle body, cast and then hand-machined individually for perfect alignment for either two, three or four throttle cables, which are operated by a magnesium throttle tube.

It is all cast and then machined in the UK and then it’s chromated to prevent corrosion.


I picked one up and could hardly believe it – my eyes felt like my hands were deceiving me.

Suitable for any multi-cylinder bikes from four-cylinder RG500s to three-cylinder GT750s or twin-cylinder RDs, they are obviously designed for racebikes where every ounce counts, but they could equally be at home on a British twin, or a road bike that wants for nothing.

You may not need one, but boy, they are so beautiful you’ll find an excuse!


Around £400 depending on spec
