Hey guys,

I have a stock 21" front tire on my 08' Vulcan 900 custom. Was wondering can I go any bigger, like 26' for instance?

Using a tape measure, put the end of the tape measure on the axle, extend the tape measure to about 16 or 17", then pivot around to see what the clearance will be. From the math a 120/55-26 tire has a radius of about 15.75". or something like that.

The bigger front wheel is going to change the geometry & possibly affect the engine oil distribution or something.
