Pro Stock Motorcycle ace Gaige Herrera has made a name for himself on the national stage at a historic clip, capturing two championships and 30 wins — including a record-tying 11 in a row during his rookie season in 2023. But lest anyone think his talents on a motorcycle begin and end as a hired gun at Vance & Hines, they would be quite mistaken.
Before his reign of terror in Pro Stock Motorcycle, the 32-year-old California native tuned and raced bikes across the country, achieving success in Pro Street and outlaw-style classes. A chance opportunity to test a Vance & Hines bike ultimately led to a full-time ride with the legendary two-wheeled powerhouse, but Herrera hasn’t forgotten — or lost interest in — where he came from.
As his NHRA schedule allows, Herrera continues to push the limits of physics with his family-owned Suzuki Hayabusa in the Pro Street class, home to the world’s quickest and fastest non-wheelie-bar motorcycles. With laps in the 6.30s at well over 200 mph already to his credit, Herrera has long been a contender, but last weekend’s Xtreme Dragbike Association (XDA) WPCG Bike Fest at Maryland International Raceway made him the target in Pro Street, much the same as he has become in the NHRA.
Riding the only nitrous oxide-assisted motorcycle in the category, Herrera blasted off a series of record-breaking quarter-mile elapsed times in the 6.30s before ultimately reaching the low 6.20s to establish a new national record on his way to the event title.
Herrera’s latest milestone came aboard a motorcycle that has been part of his life since he was 13 years old. He bought the Gen I Suzuki Hayabusa and made his first passes aboard it as a teenager, then spent the last 22 years steadily transforming it into one of the quickest Pro Street motorcycles in the world.
“I started building it when I was 13,” Herrera says. “I’ve had it for 22 years now. It’s been my baby since day one.”
While still based on Suzuki’s first-generation Hayabusa platform, the bike has evolved into a purpose-built machine with a custom DME chromoly chassis surrounding a 1,700cc inline-four engine featuring a strengthened block, aftermarket crankshaft and pistons, and a Vance & Hines-ported cylinder head. Fuel is delivered through electronic fuel injection, while a dry nitrous system provides the additional horsepower, and an MTC slider clutch coupled with a manually shifted six-speed transmission transfers the power to a DOT-approved Dunlop rear tire.
“I’ve always loved nitrous. My dad ran a nitrous Pro Street bike back in the day, and I always followed the class growing up. Everybody told me I was crazy for beating my head against the wall trying to run nitrous against all the turbos, but I like the challenge and I like being different,” Herrera says. “I don’t think people ever stayed with the combination long enough because it is difficult. I can’t tell you how many melted parts I’ve got.”
Herrera arrived at Maryland with confidence after making significant changes to the bike during the offseason, including switching to a MaxxECU engine management system and refining virtually every area of the combination. The motorcycle had previously established the nitrous record at 6.39 seconds last season, but Herrera believed there was considerably more performance waiting to be uncovered.
“You always think it’s in there,” he says. “You’ve just got to get the front, the middle and the back all together.”
Whatever Herrera and his family found during the latest round of development showed up almost immediately. He qualified No. 1 with a 6.328 to narrowly edge defending points leader Jason Dunigan, whose 6.335 came only weeks after resetting the class record at Rockingham with a 6.283.
Eliminations turned into a record-setting exhibition. Herrera opened race day with a 6.267 to erase Dunigan’s newly established mark, lowered it again with a 6.229 in the semifinals, then capped the weekend with a 6.220 at 217.25 mph in the final to defeat Dunigan, whose turbocharged Hayabusa charged to 238.89 mph but couldn’t overcome Herrera’s elapsed-time advantage.
Just as impressive as the record itself was the consistency right off the trailer, with a series of ever-quicker runs at near-record or record pace. Herrera’s stack of time slips included a best 1.038-second 60-foot time and a 4.018-second eighth-mile at 185 mph.
“A lot of it is clutch management, power management and nitrous management,” Herrera explains of keeping the rocket ship on the tarmac without the aid of wheelie bars. “I tune a lot of bikes that I don’t ride, so I’ve got a lot of data from different combinations. It’s just a lot of laps. Getting the clutch, the power and everything working together consistently every pass is the hardest part.”
Although Herrera now spends most weekends chasing NHRA Wally trophies aboard a Pro Stock Motorcycle, he believes the two programs continue to benefit one another.
“The Pro Street bike is more of a wrestling match,” Herrera says. “But riding the Pro Stock bike has taught me how to get every little bit out of this one. They’ve both got their own challenges, and honestly I just love racing motorcycles.”
The NHRA schedule will limit Herrera’s opportunities to defend his victory and the new record, but he expects to return to XDA competition later this summer at Rockingham, where another meeting with the Pro Street field awaits. Given what unfolded at Maryland International Raceway, the chase will begin with everyone aiming at the lone nitrous entry.
