From Brazilian Blues to Texas Two-Step: Toprak’s Wild MotoGP Ride
The “Stoprak” show hit a massive speed bump in Brazil, and let’s be real—it was a weekend of whiplash. One minute, Toprak Razgatlioglu is slicing through mixed conditions like a surgeon to secure a direct ticket to Q2, looking every bit the WorldSBK titan we know. The next? He’s crossing the finish line in 17th place, staring at the exhaust fumes of race winner Marco Bezzecchi from a staggering 30 seconds back.
What went wrong? The dreaded Yamaha V4 rear-grip ghost is back to haunt him. While the bike’s heart has changed, the struggle to find traction remains a stubborn thorn in the side of the Turkish star.
The Silver Lining: Aggression is Back
It wasn’t all doom and gloom in Goiania. Pramac team director Gino Borsoi is spotting a flicker of hope. They’ve finally cracked a code at the front end, giving Toprak the confidence to do what he does best: get aggressive.
- The Breakthrough: Better stability on corner entry.
- The Result: Toprak is starting to “move” the bike like a MotoGP machine rather than a passenger on a rocket ship.
- The Mission: Carry that “attacking” DNA straight into the undulations of COTA.
“In Brazil, we found some positive direction, particularly on corner entry,” Toprak noted, shaking off the 17th-place sting. “I want to build on that. Everything is still new, and riding COTA on a MotoGP bike is a completely different beast than the Rookies Cup.”
The COTA Challenge: Can the Yamaha V4 Tame the Snake?
The Circuit of the Americas is a brutal, 20-turn technical nightmare. For Toprak, his last memory of this track is from 2013 on a Red Bull Rookie bike—basically a bicycle compared to the 300hp monster he’s wrestling now.
Meanwhile, on the other side of the garage, Jack Miller is looking to reset after his lap-two disappearing act in Brazil. Thrillingly, Miller dragged the old inline-four Yamaha to a 5th place finish here last year. If the old bike could fight for the top five, the pressure is on for the new V4 to prove it can handle the “Stop-and-Go” nature of Texas.
Weekend Outlook: Austin, TX
| Rider | Brazil Result | COTA History | Goal for the Weekend |
| Toprak Razgatlioglu | 17th (Pace: -30s) | Rookies Cup (2013) | Top 10 & Entry Confidence |
| Jack Miller | DNF (Crash) | 5th Place (2025) | Podium Fight & Consistent Grip |
The Verdict
Toprak is currently in the “painful growth” phase of his MotoGP evolution. He has the entry speed; now he just needs the Yamaha V4 to stop spinning its wheels and start delivering the drive. Will the “Lone Star State” be where the WorldSBK champ finally finds his footing? Free Practice kicks off Friday.
Absolutely. Transitioning from the legendary Inline-Four to the high-stakes V4 is like swapping a scalpel for a sledgehammer. While the Inline-Four was all about that buttery-smooth “corner speed,” the V4 is built for one thing: brute-force acceleration and braking stability.
Here is the technical breakdown of the two beasts Toprak and Miller are wrestling with this season:
Yamaha M1: The Engine Evolution (2025 vs. 2026)
| Feature | The “Legacy” Inline-Four (2025) | The “Revolution” 90° V4 (2026) |
| Philosophy | “Flow & Momentum” – Maximizing lean angle and high mid-corner speed. | “Point & Shoot” – Drastic late braking and explosive corner exits. |
| Weight Dist. | Front-Heavy: All 4 cylinders sit over the front tire, aiding “feel” but making it wheelie-prone. | Balanced: Rear bank of cylinders shifts weight back, helping “dig” the rear tire in for better drive. |
| Width | Wide Load: The broad engine acts like a sail, creating more aerodynamic drag. | Slim & Mean: A narrower profile allows for more aggressive “ground effect” aero fairings. |
| The “Ghost” | Michelin Spin: Famously struggled to get power to the ground once the tire dropped off. | The V4 Gamble: Designed specifically to match the stiff carcass of modern Michelin tires. |
| Toprak’s Take | Hard to use his signature “stoppie” style; the bike wanted to “flow,” not “stop.” | Synergy: Finally allows him to use his “Stoprak” late-braking aggression on corner entry. |
Why COTA is the Ultimate Test
Austin is basically a series of drag strips connected by 1st-gear hairpins.
- The Inline-4 would usually get “eaten alive” on the back straight (the longest in MotoGP) but make it up in the flowing Sector 1 “Esses.”
- The V4 is theoretically built for this track. It should allow Toprak to “park” the bike, rotate it, and use that 90-degree V-angle to rocket out of Turn 11 and Turn 12.
The Catch? As we saw in Brazil, the V4 is still a “work in progress.” It has the aggression, but it hasn’t quite mastered the “rear grip” needed to finish a 20-lap race without destroying the tire.
The Brazil GP was a brutal case of “The Tale of Two Yamahas.” While Toprak showed he has the raw speed to run with the aliens in Practice (finishing P3!), the Sunday race in Goiania exposed exactly where the Yamaha V4 is bleeding time.
Toprak finished 17th, a massive 30.197 seconds behind race winner Marco Bezzecchi. Here is the breakdown of where those seconds vanished:
The “Bleeding” Report: Toprak vs. The Field
| Category | Toprak’s Status | Impact on Lap Time |
| Corner Entry | Elite. He was matching/beating Quartararo. | -0.0s (His strongest point) |
| Mid-Corner | Strong. Confidence in the front end was high. | -0.1s (Minor losses) |
| Throttle Opening | Disastrous. Massive wheelspin & “strange” grip. | +0.8s to 1.2s per lap |
| Long Straights | Losing. Couldn’t get the drive to use the V4 power. | +0.5s per lap |
The Technical Culprit: The “Traction Gap”
Toprak spent a large portion of the race shadowed by Fabio Quartararo, which provided a perfect “Data Mirror.” His feedback was blunt:
- The Brake-to-Apex Phase: Toprak felt he was actually faster than Fabio in the slow technical sections. He could close the gap under braking and hold it through the lean.
- The Apex-to-Exit Phase: As soon as the throttle cracked open, the V4 didn’t “dig in.” While Fabio (on the factory setup) was able to find drive, Toprak’s Pramac bike was lighting up the rear tire.
- The “Solo” Factor: A mistake at Turn 1 mid-race caused him to lose Fabio’s slipstream. Without a reference point and struggling with “pavement deterioration” (literally pieces of the track breaking off), his pace dropped into the 1’23s while the leaders stayed in the 1’21s.
The COTA Outlook
If Toprak can’t solve the “throttle opening” issue, COTA’s back straight (the longest on the calendar) will be a nightmare. He’ll be a sitting duck after Turn 11. However, if Borsoi’s “positive direction” on the front end holds, Toprak might be the late-braking king of the Turn 1 hairpin.
Fun Fact: The Brazilian track was so hot and poorly surfaced that a sinkhole actually appeared on the straight! Riders reported getting hit by “pavement stones” during the race.
