You left out some key information: 1) were you injured? and 2) year and model of your bike.
Why is this key? Because unless you were injured, what's at stake in the claim is actual cash value of your bike, and it may be hard for you to get a lawyer to represent you, unless you agree to pay on a per hour basis.
Bikes depreciate over time. Once a bike is more than a few years old, it's not worth what you might think it is worth, and what the insurance company is likely to offer is going to be less than full replacement cost.
However, if you even suspect that an injury may crop up, something that was missed by the initial exam, then you need a lawyer.
