Gearing calculator

To have me add a new bike* to the database, please fill out the form below. All necessary information can be found in the owners manual that comes with the bike or in the service manual.

All fields are mandatory except the one marked with a red star ^*.  But please also try to find the M.P.RPM (Maximum Power RPM), this is the RPM where your bike delivers the most power. This RPM is often referred to by "Maximum power xxx BHP @ xxxx RPM" and is the RPM present at the top of the power curve. If possible supply the number of chain links and the chain pitch (in mm). If you can't find the pitch, supply chain type (e.g. 520 or 530 etc). Please do not enter multiple bikes in one Add-Bike form, only 1 will be processed.

* Please note that I do not enter 'not factory default bikes' (like homemade builds, transformations, upgrades or conversions) in the Gearing Commander database. These kind of bikes are of little to no value for other Gearing Commander users.

Please fill out all mandatory fields below without using special characters:  Additional Help on filling individual fields   

Bike Setup:	Primary Drive Ratio	Tire Size Width / % / Rim	M.P.RPM	Final Drive Ratio Front / Rear	Chain or Belt Pitch mm	Chain links or Belt teeth
