Motorcycle Advice

[TVRs4eva]

Okay guys, Andrew has a big dilemna here:

I've ridden different types of motorcycles (mostly dirt bikes) on and off for about six years. However, I'm going off to college next year and I want to purchase a streetbike of some sort before I leave. Two people I know are selling their old bikes right now, a 2004 Yamaha R6 and a 2003 Yamaha R1, both in the ballpark of $4,000-$4,500.

Now then, the R6 was ridden hard its whole life and has some minor maintenance issues such as leaks and sketchy cables here and there. The R1 has low miles but the guy had to put it down at a high speed two months ago, so it's got some scrapes along the side and the crash may have caused unforseen internal damage, but for now it runs fine.

On top of this all, I live with my mother who hates all things motorcycles (my parents are divorced so I ride with my father), and she might flip out when she sees I bought one, because this last year two of her students were killed on bikes.

I just wanted to see your guys' thoughts, I've never purchased any automobile by myself and I truly appreciate any advice that anyone could give me.

Thank you.
