Which vehicle in PUBG has the highest top speed?

The motorcycle is the PUBG vehicle with the highest top speed among the listed choices.

Its advantage comes from a combination of low weight, strong acceleration, and a high maximum speed. On open, reasonably level ground, a standard motorcycle can reach roughly 150–152 km/h, making it faster than the Buggy, UAZ, or Dacia. That speed makes it useful for crossing exposed terrain quickly or escaping a shrinking play zone.

The trade-off is protection. A motorcycle leaves its riders much more exposed than a UAZ or Dacia, and it is less forgiving when landing jumps or hitting uneven ground. The sidecar version carries an additional passenger but is slower and less stable than the two-seat motorcycle.

Vehicle statistics can vary with game version, map-specific vehicles, boosts, and terrain. Newer PUBG updates have added fast cars, so broad claims about every vehicle in every edition can become complicated. In the classic comparison represented by this question, however, the motorcycle is the canonical fastest answer.
