The 2018 International Kart Federation (IKF) 2-Cycle and 4-Cycle Grand Nationals will be hosted by North Texas Karters (NTK) in Denton, Texas. Taking place from Wednesday, June 27 through Saturday, June 30, the much-heralded national karting trophy known as the “Duffy” will be awarded to the winners of each class.

The IKF Grand Nationals have long been the “granddaddy” of national kart races with the Duffy awarded to the winner of each class throughout the week. The Duffy is considered one of the highest awards in karting as the trophy honors Frank “Duffy” Livingstone, who was active in karting as a driver, mechanic, and IKF board member and before being the Series President. He was the co-founder of organized karting and the Go-Kart Club of America, which evolved into the International Kart Federation. Frank passed away in 2017 at the age of 92. The “Duffy” trophy is a bronze statuette of ‘Joe Karter,’ standing 12 inches tall and mounted on a wooden base 6 inches high.

The 2018 IKF Grand Nationals are expected to bring in a huge field of the top kart racers in the country. Most of the 4-Cycle classes will race on Wednesday and Thursday, with most of the 2-Cycle divisions racing on Friday and Saturday. Monday, June 25 will be a practice day made available by NTK while Tuesday, June 26 will be the official IKF practice day.

North Texas Karters is a member-owned facility that has been in existence since the early 1960s. The historic 1/2-mile circuit boasts nine unique turns including two sweeping banked turns providing incredibly exhilarating racing with several passing opportunities. Located in Denton, Texas, NTK is a 45-minute drive north of Fort Worth and Dallas. In 2016, NTK hosted the 4-Cycle Grand Nationals, which fielded a large number of Briggs & Stratton 206 racers.

Punches are not required for this IKF Grand Nationals event. However, all participants must be an IKF member. Spec tires will be the Evinco Tires with the Evinco Blue compound utilized for all 4-Cycle classes, including Kid Kart, while the Evinco Red compound is reserved for all 2-Cycle divisions. One new set purchased is mandatory per driver.

Registration is currently open, with a deadline of June 16. Entry form along with all other information regarding the 2018 IKF Grand Nationals is available at:
