March 12 2004. Performance Parts, purveyors of serious bits to the more rapid sector of the motorcycle trade, have new lines coming in. Like Remus road legal slip-on silencers for Yamaha's 2004 R1, with alloy sleeves at £536 retail for the pair, or with carbon or titanium versions for £674. All prices inclusive of VAT.

From Akrapovic comes a complete race system for Kawasaki's new ZX-10, retailing at £886 or in titanium for a serious £1210. Expect a range of slip on silencers to match very soon.

Hawk Kawasaki, the official Superbike team in 2004, will be running with the Akrapovic system in the British series. More information from Colin Peabody at Performance Parts on 0870 240 2118 or e-mail cp@performanceparts-ltd.com
