From 1999, there were three different models of the 996: a base, or Biposto; the 996S with Öhlins suspension; the 996SPS (Europe only) which had a more powerful engine and less weight thanks to some titanium and carbon fibre parts.
In 1999 the rear shocks were made by high quality Swedish suspensions manufacturer, Öhlins with Showa front forks.
The adjustable steering head also allowed geometry changes to the steel tube trellis frame making it suitable for different riding styles or race tracks.
In 2001 Ducati introduced the limited production (only 500 were built), 996 R, the suffix standing for ‘Racing’, which featured Öhlins suspension (rear and front), carbon fiber bodywork, a revised and more streamlined fairing, but most importantly the newly redesigned engine, the Testastretta (narrow-head) which actually displaced 998cc.
It featured more aggressive camshafts, titanium conrods and a shorter stroke and wider bore, which allowed it to rev more safely at high RPMs.
Ducati updated the bike with Öhlins front forks, which featured a titanium nitride coating on the stanchions to minimise friction.
