I was using the 80/90x18 Avon race tire. The small Dunlop wasn't readily available in race compound. The Dunlop tire is noticeably lighter than the Avon and I think that is a very important factor. I plan to try the Dunlop "KR" race tires when those wheels are fitted to a 250cc Motobi I'm going to build.
The Avons did work fine for the speeds I felt comfortable going. I used Avons on the Cagiva and Laverda too.
cheers,
