Third place in both F1 Sidecar events went to the Wairarapa crew of Spike Taylor and Astrid Hartnell on another LCR machine. Former Whanganui lads Adam Unsworth and Stu Dawe were fifth.
A year ago Horst Saiger had arrived in New Zealand for the Suzuki Series as something of wildcard. He won at Hampton Downs and took out the Suzuki series, so his 2015 return - again riding for the Hamilton-based Red Devil Racing - is accompanied by no element of surprise.
Saiger claimed pole position for the F1 Superbike class - by just 0.13s from Wellington's Sloan Frost (Suzuki) - and won both races on the Kawasaki ZX-10R.
Race one was split into three and nine lap segments by an early red flag incident but Saiger was in front on both occasions. The second portion of race one saw close battles for second with Andrew Stroud (Suzuki) edging out Frost while Whakatane's Tony Rees (Honda) who Taupo's Scott Moir (Suzuki) for fourth.
Frost made a strong start in race two and was on Saiger's tail throughout while Stroud finished third ahead of Rees and Moir.
Swiss racer Stamm (Kawasaki ZX-6R) faced some close competition from Aucklander Daniel Mettam (Suzuki) and Wellington's Shane Richardson (Kawasaki) in the F2 races but produced two wins to complete a successful day for the Red Devil squad. Mettam had two seconds and Richardson was third in both races.
The other four classes also produced Hampton Downs double winners.
Taumarunui's Leigh Tidman (Yamaha RS450) edged out Hamilton teenager Jacob Stroud in both F3 Sport Bike races while John Oliver (Feilding) secured a BEARS double on his BMW S1000RR.
Veteran Eddie Kattenburg (Te Awanga) won both Pre-89 Post Classic races on his rare Bimota YB8 and some entertaining SuperMoto battles saw Whanganui's Richard Dibben (Honda) take two wins while Tauranga's Duncan Hart (Yamaha) and Reporoa's Casey Bullock (KTM) split the podium positions.
Suzuki Series round two is raced at Manfeild on Sunday and the series finale is the annual Boxing Day Whanganui street race meeting.
