Be VERY CAREFUL what you might be suggesting.
A very quick look at Bikers Travel policy on their website shows quite clearly one very plain and important EXCLUSION relating to Personal Liability:
Section F Personal liability.
EXCLUSIONS APPLICABLE TO SECTION F
The Insurer shall NOT pay for any claim arising out of:
1. the ownership, possession or use of any aircraft, yachts or mechanically propelled vehicle including watercraft.
In short: A motorcycle is a mechanically propelled vehicle, your third party liability arising from your use of it is NOT covered.
That is a very standard EXCLUSION under most 'off the shelf' policies. The reason, why? Because conventional motor insurance in most / all countries covers your legal liability, just as it does in the UK.... So, if you go to America, you will need to buy American motor insurance to ride your bike, just as a septic coming to the UK would have to.
Other than that, the Liability section is near enough standard and much as you would see under any run'o'the mill Travel policy.
==========
The Legal Expenses cover is nothing special and is available under most bog standard Travel insurance.

ONE VERY BASIC RULE OF THUMB:
Be very wary of any policy sold or branded as 'Biker friendly' / 'Made for bikers' or some such bollox.... Very few, if any, are.
SECOND VERY BASIC RULE:
Read the policy, carefully. They are always written in very plain English.
