Power on that bike is fairly manageable. If you are a timid rider, unsure of your abilities, it isn’t the bike for you (at the time it was a moderately large bike meant for people who had progressed up from 170s, 250s, or 350s). Certainly not an impossible bike to learn on, just not as easy as they come.
Look into parts and maintenance. Parts and mechanics who know bikes that old are getting few. Make sure you have a local mechanic who has experience and confidence with bikes that old. I can’t overstate the importance of having a good supply of parts for a bike that old.
