William Dunlop scored his first international Superbike victory when he won the Joey Dunlop trophy at Floberg in Germany yesterday.
Dunlop led from start to finish and atoned for his bad luck in the previous Superbike race when his chain broke as he led on the last lap.
Dunlop said: "It's great to win a race which is named after my uncle. As everyone knows Joey was a legend and competed many times in this part of the world.
"This has capped a great season for me. I won the 250cc Irish Championship, but this Superbike win means something special."
Dad Robert could manage only fifth in the 125cc class and said: "It just wasn't my day, but I'm delighted William has carried the family flag."
On the moto cross scene, Crossgar-based Wolfsport Kawasaki team were successful in the penultimate round of the British Masters Championship at Matchams Park as Shaun Simpson won both MX2 races.
The final round of the championship is at Foxhill in two week's time, but before then Simpson and team member Mark Jones will compete in next weekend's final round of the Ulster Championship on the grand prix circuit at Moneyglass, venue of this year's Northern Ireland Grand Prix.
Meanwhile James Toseland's pursuit of a second World Superbike Championship will go to the final round after a crash in the second race of the 12th round in Italy.
HANNspree Ten Kate Honda rider Toseland will travel to next weekend's finale at Magny-Cours in France with a 29-point lead over Alstare Suzuki rider Max Biaggi and is still in prime position to regain the crown he won in 2004 with just 50 points available.
Toseland claimed third in race one behind Biaggi and Xerox Ducati rider Troy Bayliss at the Vallelunga circuit near Rome but crashed in race two as Bayliss won.
