Explanation:

"Motorcycle"
what kind of motorcycles

"Max speed"
the maximum speed in Km/h (Conversion formulas)

"Acceleration 0-400m (time/speed)"
the first value represent the time to reach 400 meters starting from 0 speed
the second value is the motorcycle's speed across the 400 meters line

"Recovery 0-400m (time/speed)"
the first value represent the time needed to reach 400 meters starting at 50 Km/h in the upper gear
the second value is the motorcycle's speed across the 400 meters line

"Max. power"
the first value represent the maximum power in CV (Conversion formulas)
the second value represent the RPM to get the maximum power

"Max. torque"
the first value represent the maximum torque in Kgm (Conversion formulas)
the second value represent the RPM to get the maximum torque

"Urban & extra-urban cons."
the first value represent the urban consumption in km/liter
the second value represent the extra-urban consumption in km/liter
(Conversion formulas)

"Braking from 60Km/h & 100 Km/h"
the first value represent the space, in meters, needed to stop the motorcycle running at 60 km/h
the second value represent the space, in meters, needed to stop the motorcycle running at 100 km/h

"Weight"
represent the weight of motorcycle with 5 Kg of fuel and without oils and other liquids (Conversion formulas)


I thought to add here some formulas to translate values across different measurement systems

Speed Conversion
Km/h * 0.62 = mph

Power Conversion
CV * 0.735 = kW
CV * 0.986 = HP

Torque conversion
Kgm * 9.81   = N m
Kgm * 7.233 = lb ft

Consumption conversion
Km/liter * 2.824 = mile/gal (British)
Km/liter * 2.353 = mile/gal (USA)

Weight Conversion
Kg * 2,2 = lb
