Parity in NHRA’s Pro Stock Motorcycle class has been an ongoing issue all season.

At the season-opening event for the class at the Gatornationals, reigning world champion Eddie Krawiec established new NHRA Pro Stock Motorcycle national records with a 6.750-second elapsed time and a 199.26 mph speed aboard his Screamin’ Eagle Vance & Hines Harley-Davidson.

The second fastest elapsed time by another manufacturer other than Harley-Davidson at the Gators came from Hector Arana Jr. Arana Jr., clocked a 6.812-second time to qualify second on his Buell.

NHRA addressed the issue of parity in the Pro Stock Motorcycle class March 20 by increasing the minimum weight for the Harley Davidson 160-cid, 4-valve combination by 20 pounds, from 640 pounds to 660 pounds.

That has done nothing to slow down Krawiec and his teammate Andrew Hines at all. Krawiec (five) and Hines (three) have combined to win all eight of NHRA’s Pro Stock Motorcycle national events this season.

Dating back to the Las Vegas fall race last season, Hines and Krawiec have won 10 races in a row. Krawiec and Hines are the only Harley-Davidson riders and Harley-Davidson also is the official sponsor of NHRA.

“As always, the NHRA Technical Department is reviewing data to help determine what if any changes need to be made,” Glen Gray, NHRA’s Vice President, Technical Operations, said to Competition Plus Wednesday. “In addition, we have been speaking with members of the newly formed Pro Stock Motorcycle Technical Advisory Council to get their opinions. This is an ongoing process and no decisions have been made.”

Gray said there is no timetable on when NHRA will make a decision.

By analyzing the year to date quickest runs per engine combo, it illustrates the Harley-Davidson domination.

The year to date average run for Harleys is 6.914 seconds, while the Buells came in at 6.919 seconds. Suzuki has a 6.968-second average time.

Back on March 16, Gray addressed the issue of parity in the Pro Stock Motorcycle class with Competition Plus.com.

“We have some trigger points with respect to performance,” Gray said. “Basically if any manufacturer has just a single run that is more than five-hundredths quicker than any of the other two manufacturers because we have three combinations out there really (Harley-Davidson, Buell and Suzuki) then that would trigger a review of parity. What that means is we are pretty much reviewing every race anyway. We run numbers on this after every race, but when we do a review that means we will get a little more serious and dig down a little deeper. We will start to review previous races from last year and see if this is a one-race thing or is something that is going to be a trend that continues or was there a trend leading up to this in previous races. The other thing that can trigger a review is we take the four quickest runs from a manufacturer and we average them, and if the average of those four quickest runs and the difference is more than three hundredths between any of the manufacturers that will also trigger a review.”

Using the four quickest run average measuring system, this season Harley is 0.002 faster than Buells and 0.065 faster than Suzukis. The difference between the Harleys and Suzukis should trigger another review. The Buells are also 0.063 faster than Suzukis.

The Pro Stock Motorcycle class returns to action at NHRA’s Lucas Oil Nationals Aug. 16-19 at Brainerd (Minn.) International Raceway.
