Hi Dan, appreciate your posts. As an old newby racer myself your an inspiration to get out there and do it. One day I hope to make it to SoCal and Glen Helen!
Don't look at comments much, but yes there are some 125 that come out. I started on one but the hills at Glen Helen are a bit much, but it was still fun. All the other tracks we race are no issue for a small bore 2 stroke.
