Seven things to know for the motorcycle races at Road America this weekend

The MotoAmerica’s Dunlop Championship runs Friday through Sunday at Road America in Elkhart Lake, highlighted by 13-lap Superbike features at 3:30 p.m. Saturday and Sunday. Other classes racing are Supersport, Stock 1000, Twins Cup, Junior Cup and KTM RC Cup.

Here are seven things you ought to know:

1. Reigning Superbike champion Toni Elias, a 35-year-old, Suzuki-riding Spaniard, has won five of six rounds so far. Road America will always hold a special place in the heart of Elias, a Moto2 world champion and MotoGP winner. The doubleheader last year was the first time his parents had seen him race in the United States, and he treated them to a victory Sunday.

2. In four of Elias’ victories, he has been followed by Yamaha's Cameron Beaubier. The winningest active rider in the series, Beaubier has been victorious five times at Road America – including over Elias by 0.0005 of a second in last year’s Saturday feature – but has been shut out since August, an 11-race drought that is the longest of his career.

3. Westby Racing’s Mathew Scholtz is the only other winner this year, in the wet at the Circuit of the Americas. The 25-year-old South African rider has been on the podium after five of six events. A year ago at Road America, Scholtz won one of the two features in the Superstock 1000 class (which no longer exists), and he went on to take the title.

4. Josh Hayes, who dominated Superbike competition at Road America in the first half of the decade, was replaced in the off-season by 22-year-old Garrett Gerloff on the Monster Energy Yamaha team. Hayes, 41, won eight times at Road America in a span of 12 races, a string that concluded in the second half of the 2015 doubleheader.

5. Gerloff has finished third twice but also crashed out of two races, most recently at Virginia International Raceway, where he took to other riders with him. Gerloff won the past two Supersport titles.

6. JD Beach has won three of the four Supersport races this season. He and Gerloff swapped 1-2 finishes with the Graves Yamaha teammates waaaaaaaaay ahead of the rest of the field in last year’s Road America rounds.

7. Norwegian Caroline Olsen is scheduled to return to Supersport competition 8½ months after a mechanical failure led to a crash that left her with severe bruising on her lungs, fractured vertebrae, a displaced fracture of a collarbone, a right broken leg that wasn’t diagnosed for weeks and concussion symptoms that lingered.
