Motorcycle Riding & Gear Calculators
Free tools for the numbers behind riding — chain & sprocket ratio, gear speed, fuel range & cost, lean angle & cornering, tyre size & speedo error, and riding gear fit & sizing.
Chain & Sprocket Ratio Calculator
Get your final drive ratio from front and rear sprocket teeth, then compare a new pair to see the trade between acceleration and top speed
Gear Speed Calculator
See your road speed in every gear from engine RPM, rear tyre size, and the primary, gearbox, and final drive ratios
Fuel Range & Cost Calculator
Estimate how far a tank takes you from capacity and economy, plus the fuel and cost for a planned ride — in L/100km, km/L, or mpg
Lean Angle & Cornering Calculator
Find the lean angle a corner needs from its radius and your speed, or the max speed a given lean can hold, with θ = atan(v²/(r·g))
Tire Size Converter & Speedo Error Calculator
Turn a size like 180/55-17 into overall diameter and circumference, and compare two tyres to find the speedometer error
Riding Gear Fit & Sizing Calculator
Turn your head, chest, and hand measurements into helmet, jacket, and glove size bands, with how to measure and what a correct fit feels like
Motorcycling Museum
Explore an immersive museum of the machines, gear, and moments that shape motorcycling — landmark bikes and engines alongside the evolution of helmets and protective kit, the great races and the culture around them, each in its own gallery, so you can get to know the stories behind the sport: how each piece came to be, what makes it matter, and the role it plays in how we ride today.
