Raw ma­te­ri­als and the tube mill

Motorcycle News (UK) - - FEATURE -

Akrapovič pre-or­der the spe­cial ti­ta­nium al­loy a year-and-a-half in ad­vance from one Amer­i­can and two Ja­panese sup­pli­ers, typ­i­cally to a value of £5-7 million. The tube mill is a long amal­ga­ma­tion of cogs and presses that looks like a 19th cen­tury ma­chine, whizzing and pop­ping with steam. It’s rare for an ex­haust man­u­fac­turer to pro­duce their own tubes, but Akrapovič took the risk. The ti­ta­nium is de­liv­ered in coils; the coil is fed into the ma­chine like yarn, rolled into a tube, welded and smoothed in one con­tin­ual process.
