My 18 year old little brother is looking to get his first bike. He wants to be able to ride with me and some of my friends that have power cruisers but I don’t think a warrior is a great first bike to learn on. He is 5’5” so he needs something with a lower seat height. I am worried that he will be bored with something like a vstar 650 or shadow 750 after a couple of weeks. He is looking to spend 5k or less. I am thinking magna, m50 or sabre if anyone has one of these bikes and can provide pros/cons or give an opinion on if it would be a good first bike that would be great. Any other insight would be appreciated.
