Round five of the 2021 World Motocross Championship was significant fro a handful of reasons: (1) Jeffrey Herlings is injured and couldn’t race in the Czech Republic. (2) Tim Gajser threw it away in the second moto and saw his large points lead reduced to 11 points. (3) Tony Cairoli is suddenly a player in the 2021 450 World Championships. (4) 250 World Champion Tom Vialle returned to racing after recovering from a hand injury and, after finishing second in the first 250 moto ,he crashed and crashed again in moto two—and eventually retiring to the pits. (5) Mattia Guadagnini took the overall 250 Grand Prix win in Czecho, making him the winningest 250 rider of 2021. (6) The season is only up to round five of 18 races, so it doesn’t matter what the points total is now, there are 13 more races to go.
