I'm looking to get my first bike and the CBRs have caught my interests, more specifically the CBR500, but used ones aren't as apparent in the market. I see a lot more CBR300s in my area but I think the CBR500 is a good in between without going to a 600. I'm 6' and 190 pounds and will be using the bike to commute, highway, downtown, suburban areas, etc. Would the 300 be too small for the highways, I would assume it would just be high revving but bikes can handle that. Also is it worth it to try and get the 500 instead? Is there a difference in highway riding? Thanks!
