Nice small unit, but questionable for motorcyle use.
First, it is not waterproof, but, many don't ride in bad weather. Do you? If so, you could always store it during bad weather.
Second, the audio is through a built-in speaker and I don't recall it having an output for an external speaker.
Third, it has a click wheel that MIGHT be a challenge in gloves. If you are still interested, go to a local store with your gloves and try it out!
