NHRA Technical Department Makes Parity Adjustment to Pro Stock Motorcycle

Based on Pro Stock Motorcycle performance numbers from the last portion of the 2018 season through the first race of the 2019 season, the NHRA Technical Department is increasing the minimum weight of the Harley Davidson, Victory, EBR and Buell motorcycles from 625 pounds to 640 pounds. All other motorcycle minimum weights will remain the same: (Suzuki, 2-valve, 107 cid – 590 pounds), (Suzuki, 2-valve, 113 cid – 600 pounds), (Kawasaki, up to 107 cid, 2 or 4-vavle – 575 pounds). This rule change will go into effect immediately. NHRA reserves the right in the future to make additional rule changes to control performance and maintain parity in the category.
