Well a starter motor from a motorcycle will run quite happily off a motorcycle battery!

Perhaps you need to pin your question down a bit more. What voltage is your motorcycle battery? What amp-hour rating does it have? What voltage is your grass trimmer motor supposed to run off? What power is it rated at? What are you actually trying to do?

You're not going to get 120 volts from a motorcycle battery. You may want to rethink your numbers.

If you want to run your 120v AC trimmer off a motorcycle battery you can pick up an inverter at an auto parts store.
The inverter converts the 12v DC to AC.
How long it will run before the battery gets discharged depends on a lot of factors.

Or something like this may be of interest
