I was initially hesitant to take my RE on the highways around Philly for a number of reasons (inexperience, reckless drivers, concern about the bike holding up). Well after riding my beauty for almost 2 months, I've graduated from back roads, to business routes, to now the highway. I took my first trip on I-95 yesterday, following a 250 roundtrip ride this past weekend on I-81, I-83, I-283, Rt. 30, and I-76.
I must say, the bike holds it's own. I'm not used to being passed on the highway, but I have no problem cruising @ 60-70 mph and letting all the busy-bodies pass me by. My only thought is that I should be cautious of how long I keep the bike near maximum throttle since it's a newer bike (just approaching 870 miles). But I'm not sure if this applies to the new EFI bikes or not. I switched out the oil for the second time @ 780 miles, and the chain tension, brakes, tires, all look fine. Still haven't figured out my MPG, but I'm guessing anywhere from 40-60 mpg depending on where I'm riding.
