MotoGP heads into the Japanese Grand Prix with more questions than answers, as the resurfaced Motegi circuit prepares to host the championship for the first time on its new asphalt.
The 4.8km Motegi Mobility Resort was completely resurfaced between 2025 and 2026, changing the conditions riders and teams will face this weekend. While other racing categories have already used the circuit, MotoGP teams have little relevant data from the new surface to rely on.
That means the usual references from previous Japanese Grands Prix will have limited value. Teams will have to spend Friday working out how the new asphalt affects grip, tyre performance and bike setup.
Honda, however, has one important advantage.
The Japanese manufacturer owns the circuit and carried out a private test there just over a month ago. Development rider Takaaki Nakagami completed extensive running on both Honda's current 1000cc MotoGP bike and its upcoming 850cc machine, giving the manufacturer valuable information ahead of the race weekend.
Nakagami has since been handed a wildcard ride for the Japanese GP, allowing Honda to make further use of his knowledge of the new surface.

The 34-year-old said the resurfacing had removed the bumps that previously affected the circuit, leaving a much smoother track. However, he warned that a smoother surface does not necessarily mean immediate high grip.
For Honda's rivals, understanding that difference could be one of the biggest challenges of the weekend.
The tyre situation adds another layer of uncertainty. Michelin has brought a harder range of rear compounds than it offered at Motegi last year, with all three options moving one step harder.
The hardest rear tyre also features a reinforced casing similar to the construction used at the Austrian Grand Prix in Spielberg. The change has been made in response to the characteristics and unknown demands of the new asphalt.
Teams will therefore need to quickly establish how the revised tyres work with the new surface.
“We need to understand what the difference is and how we need to adapt,” Gresini rider Alex Márquez said.
Honda's private test could prove particularly useful here, as Nakagami was able to gather data on the new tyre constructions during his running at Motegi. While rival teams will be learning about the tyres from scratch during the official sessions, Honda already has a baseline to work from.
Not everyone is convinced the hardest option will be useful for Sunday's race, however.
KTM rider Jack Miller was particularly dismissive of the hardest tyre, joking that he would “pack up and go home” if he had to use it. The comments reflect a wider feeling that the soft and medium options could potentially provide enough durability for the race without requiring riders to use the most rigid compound.
And just when teams thought they had enough variables to deal with, the weather could add another.
Forecasts currently point to a 40% chance of rain on Sunday afternoon. Motegi sits around 70 kilometres west of the Pacific Ocean, meaning conditions can change quickly and could introduce another major factor into an already unpredictable weekend.
Wet weather would force teams to reassess their setup and tyre choices while giving riders who are comfortable in changing conditions an opportunity to gain an advantage.
With a completely new racing surface, revised Michelin tyres, Honda's private-test data and a potential risk of rain, the Japanese Grand Prix could offer very little resemblance to previous MotoGP visits to Motegi.
For most of the grid, the weekend will be less about relying on past experience and more about figuring out the circuit as they go.
