About RidePlanet

Riding and wrenching throw up a scatter of half-answered numbers. If you swap to a bigger rear sprocket, how much acceleration do you gain and how much top speed do you give up? What speed does the tacho really mean in each gear? How far will a tank take you, and what will the fuel for a long ride cost? How much does a corner ask you to lean at a given speed? Does a taller tyre throw off your speedo, and by how much? And what helmet, jacket, and glove sizes match your measurements? None of these are hard on their own, but working them out by hand, every time, is where the fun turns into a chore.

RidePlanet exists to take that arithmetic off your plate. Rather than long articles you have to read end to end, the site is built around a set of small, single-purpose calculators, each aimed at one part of riding and maintaining a bike. The Chain & Sprocket Ratio Calculator turns front and rear tooth counts into a final drive ratio and shows how a change trades acceleration against top speed. The Gear Speed Calculatorworks the whole driveline — primary, gearbox, and final drive against your rear tyre size — to give road speed in every gear. The Fuel Range & Cost Calculator converts L/100 km, km/L, or mpg into range and the fuel cost of a planned ride. The Lean Angle & Cornering Calculator applies the physics of a steady turn, θ = atan(v²/(r·g)), both ways. The Tire Size Converter & Speedo Error Calculator decodes a size like 180/55-17 into real diameter and circumference and compares two tyres for speedometer error. And the Riding Gear Fit & Sizing Calculator maps your head, chest, and hand measurements to helmet, jacket, and glove size bands, with how to measure and what a correct fit feels like.

Beyond the calculators, the blog and learn section cover helmets, jackets, gloves, boots, and protective gear, along with the reasoning behind the numbers the tools produce, and the motorcycling museum is a browsable collection drawn from Wikipedia and Wikimedia Commons, with every entry, image, and fact credited to those public sources.

A few things worth stating plainly. RidePlanet is an independent site, not affiliated with any helmet, gear, or motorcycle manufacturer, nor with any safety-standards or certification body it references. It is supported by advertising, which is how the tools stay free with no account required. Every result the tools produce — a drive ratio, a speed, a range, a lean angle, a size band — is general guidance built on the figures you enter and on standard formulas and common sizing charts, not professional or safety-certification advice. Gearing and speed results assume nominal tyre and driveline figures; sizing varies by brand and by leather versus textile, so always try gear on before buying, and confirm tyre fitment against what your bike and rim are rated for. If something looks off in a tool or an article, or you think a calculator is missing that would help, the contact page is the place to say so.
