MOTOR MADNESS EXPLAINED - Gravity/Turn 1 Motors, What You Need to Know
Good morning racers,
With the 2026-27 version of the TOUR rules being released, we've received a number of questions on the new Turn 1 motors, what the heck are they, what classes they're going to run in here at PRW, etc. As most of our racers know by now, we offer all TOUR classes at our events and each of those classes use the most up-to-date TOUR rules. Here's the roadmap for the PRW Events season regarding the new motors, plus some class name updates:
WHAT ARE TURN 1 MOTORS:
- Turn 1 motors are sourced by Paul Lemieux of Gravity RC and are a single-wind design, custom made for TOUR carpet oval racers. Paul has given us a great opportunity to have the closest spec racing we've ever seen, as the motors are much easier to keep in close resistance tolerance using this single-wind design. Racers also have the ability to install aftermarket bearings, align the sensors and adjust gearing/timing to their preference. This is why "21.5" and "17.5" are in quotes below, as they technically are not 21.5 or 17.5 turns - the motors are intended to simulate 21.5/17.5 speeds. TOUR has pivoted their wording of the affected classes to omit the motor turns as a result.
TURN 1 MOTORS APPLY TO:
- Sportsman RTT ("21.5")
- Stock FTC ("21.5") - name changed from 21.5 Truck in response to motor/body update
- Pro Stock FTC ("17.5") - name changed from 17.5 Stock in response to motor update
TURN 1 MOTORS DO NOT APPLY TO:
- Stock RTT, SK Modified, 1/12 Stock. These three classes now allow any ROAR-approved 17.5 motor, INCLUDING the prior Tekin SPEC-R2 17.5 motor, so your Tekin is NOT a paperweight. TOUR has allowed a grace period for epoxy design motors through the completion of the 2026-27 carpet oval season (May 1, 2027)
- No need to grab your torches and pitchforks - we firmly believe the Tekin SPEC-R2 will be a competitive motor in all three of these classes due to its epoxy stator design. Should you want to try a new motor, competitive options include offerings from R1 Wurks (V30R), Exalt (Gen-X), Hobbywing (G5), and more
- To reiterate, any ROAR-approved 17.5 motor is allowed in these three classes, and TOUR is not strictly following ROAR's 12/31/2026 cutoff of epoxy designs. Epoxy motors will be allowed through the conclusion of the 2027 TOUR Nats (cutoff: 5/1/2027)
We hope this helps clear up any confusion on the motor situation for 2026-27. We will be heading to Mahoning Valley Speedway this weekend to attend the Keystone Classic, the first race with these new motors. We look forward to watching the racers and motor tuners figure out these new motors; fully expect some seriously close racing once everyone gets laps/experience. Club racing at CRC Raceway starts up on Saturday 9/19/26, and the Putnam Race isn't too far off either (11/19 thru 22)!
