When the Full Throttle WaterX series was first announced, all of us at The Watercraft Journal jumped to help spread the news. In fact, WCJ was first to do so, back in late October of 2021. And true to our commitment, all updates, major announcements and most importantly, event coverage will be published on the world’s most popular personal watercraft magazine before anywhere else.

One of the greatest promises made by the Full Throttle WaterX team was its commitment to provide races in venues that racers prefer, and true to form, a recent Facebook post announced a full and comprehensive list of Vintage classes that are sure to excite many as they roll back the clock over 30 years. Below is the announcement but we’ve included a link to the original post HERE.
