Santa Monica, Calif. – Four piston strokes. Electronic Fuel Injection. Slim headers without an expansion chamber. Sleek, non-clunky, space-age plastics. This is a list of things you won’t see at the 2018 Red Bull Straight Rhythm. And when the event returns to Fairplex in Pomona on October 20, you’ll hear it coming. From, like, miles away. Because there will be only two-strokes racing. Ring-a-ding-ding. That’s right, the event will step back in time to an era where gear sets were mostly pink, Fresno was smooth and a nac nac was totally rad (kind of still is). Riders will leave their fancy factory four-strokes at home and will run what they brung as they tackle the ½-mile-long straight rhythm track on nothing but two-smoke power.

After the two-stroke class was introduced at the event last year, nostalgia took full effect, and everyone cared about little else. While most of the action took place on the track, it also got pretty heated online, as riders like Ryan Villopoto, Chad Reed and Ronnie Mac talked serious trash to each other long before lining up to race. This year all the fat has been cut, and there will be half as many piston strokes but twice as much fun. The race will consist of two classes - 250cc+, and 150cc & under. And, yes, it is all two strokes…well, with one exception. Those mad scientists at Alta Motors will be allowed to run electric in the 250cc+ class. Think of it as a “return to the past, but keep an eye on the future” philosophy. But mostly two-strokes. Lots of two-strokes. Like, 96.2 percent two-strokes. Maybe check that math.

Despite the bike changes, the concept remains the same. Line up side by side and race head-to-head down a ½ mile of rollers, whoops, doubles, tables and all other kinds of rhythmic insanity. Racing is a best-of-three format, so each rider gets at least two chances to grab victory. This also helps to cut down on all the crying about bad starts at the after party. In its fifth year, the event will continue the format where practice, qualifying and racing will all take place on the same day, with the finals taking place at night under the lights.

Red Bull Straight Rhythm debuted in 2014 at the Auto Club Raceway at Fairplex in Pomona, and saw James Stewart win in the Open Class, with Marvin Musquin taking home the top spot in the Lites Class. In 2015, James Stewart defended his title, once again landing on the top of the podium in the Open Class, with his brother Malcolm taking first place in the Lites Class. In 2016, Marvin Musquin returned to the event and dominated the Open Class, with Shane McElrath taking the win in the Lites Class. Last year’s event introduced the two-stroke class, and saw Gared “Stank Dawg” Steinke win in the class, with Marvin Musquin winning the Open Class and Shane McElrath taking the win in the Lites Class.
