I also matched the Savage against a couple of those "Your Speed Is..." signs & found unlike most bikes it to be pretty accurate (with a "standard/stock" tire on), unlike my other bike which like all BMWs is around 10 mph "flattering" @ about 75 (ie the "speedo," to use an old English nickname, reads 85 mph).
Sure wish it was easier to change around the gearing than it seems to be - I recall messing around to my hearts content with front & back sprockets on a Honda 650 single enduro I owned a few years ago.
still, I think I just want to tinker - I like acceleration & wouldn't want to lose it & think the top speed on the Savage, considering its weight, is good enough for me.
