Shouldn't you be asking them? LOL. I've done a MidAtlantic Ducati Club trackday on my R6... so I want to say I doubt they'd make you have a Duc. Besides, they'd be smart to let you in, you might enjoy seeing all those Ducs and hearing their riders rave about 'em, and maybe you'll turn into a future Ducati owner.
You need to ask them. If they reply "No we are elitist snobs who thumb our noses at your Japanese trash" you should reply with "Thank you good sir, please keep me in mind when your day doesn't fill". I was in a similar situation myself when considering a date with Houston Ducati at MSRHouston. Although their courteous response was nothing like what is listed above they still said Duc only. I thanked them and asked that they contact me if the event didn't fill. Sure enough they sent me an email asking if I still wanted to participate. Unfortunately this broken cbone and bum foot will keep me out.
They are also one of the largest Suzuki dealers in the Midwest! They are a fantastic supporter of STT and track riding in general. What event are you thinking about? Monte
Wed, June 7 at Road America. Every person on the track might pass me, on my $800 f2, with their super expensive ducs, but I guarantee I win on the dollars-to-fun ratio! :lol:
