After months of extensive R&D and testing, the MBP collets for Desmoquattro applications are now shipping.

For the Desmoquattro Ducatis, Daytona 2001 was a story of broken valves and collet replacement after each race and practice session.

Scot Dormier Racing (Ducati Seattle/ MBP) and Monroe Motors' 748 and 748R's went the distance with MBP 4v collets - maintaining correct valve clearance though the course of the events and all the rest of the racing season.
