The British Speedway Forum has been bringing fans together for over 30 years. During that time it has been far more than just a discussion forum—it has been a community. Members have shared countless moments of fun and enjoyment, formed lifelong friendships, including marriages, and, sadly, mourned the loss of fellow members. Through all of life's highs and lows, the forum has endured and continues to thrive, remaining a place where speedway fans can connect and keep the community alive.
