DOES THE WEIGHT OF A BIKE AFFECT THE ANGLE AT WHICH IT LEANS IN A BEND?
This seems like a reasonable question: if you take a bend at a certain speed when two up, does the bike lean more than it does when one up?
Well the answer is NO.
What does affect the Lean Angle is the speed of the bike and the radius of its track through the bend.
The weight of the bike, whether it’s a big bike or a small bike; whether it’s one up or two up makes no difference to the lean angle!
How do we know this is the case?
By simply analysing the physics of a bike leaning over in a bend, we can derive a formula that allows us to calculate the ‘lean angle’. If the derived formula does not contain any reference to the mass of the bike and rider; then the mass will not affect the lean angle!
