Power for a new rider is safe and still cruise 65 plus, if on highway.
The only issue might be the weight of the bike for anyone below avg strength. Sooner or later all riders get there bike a bit off balance. This can be over come by practicing with someone in the garage. Slowly moving the bike off center and back to center getting use to the weight increase with the angle increase. As well as how far is too far since there will be no helper at a stop light or sign.
The goal is really to see for yourself, how far can the bike lean over <b>before</b> your leg/kickstand starts to scream for help. Also holding the front brake and keeping the wheel straight at a stop will keep the bike from wanting to roll under you if your leaning the bike too far over.
Its embrassing for anyone to dump it when fully stopped.
So practice how your bike feels when its leaning at a stop with a helper before hitting the road.
