Whatever the speed limit allows, the bike will do.  At least here in the States.

Bike will do it a LOT longer than you can.

GOOD cause hear I come Nevada.... thanks guys..

The engine will have plenty of time to cool at gas stops, while you walk around trying to get the circulation restarted in your hind end. I've had mine up to 87mph, but I think she'd do more. I just won't do more. 70-75mph - no problem.

whats a fork brace?

i've ran thumper 80mph for hrs on end. high speed riding on the savage takes a break in period, i mean you have to break your self in.
it's a very light bike and takes some getting used to the feel. some run braces, some run farings,  i prefer a good old fashioned bobble head, that's mine i'm speaking of.

like savagew said on the first leg of the fssnoc trip. "i've never ridden 80 before",  ours was not a prolonged trip at 80, just a pass on one section,  we then hit the slab and kept to around 73 in a 70 zone, we got passed alot but that was ok,  i'de rather slow down than make some one speed up.  

two seasons ago i got a ticket doing 80 on the slab, on my way to pay a ticket for doing 80 in a county next over to mine. theres nothing like taking a big ole juicy bug on the glasses.  green slime all over the nose. hurts like heck.

I'm going to disagree with most of the people here that say running a MC at or near top speed is a "safe" speed. While you may not destroy the engine because of speed, from a Motorcycling point of view it is not a safe thing to do because there are times when you need a response when you twist on the throttle. I think that with a 190 pound rider around 55 is the top "safe" speed to run at with a stock Savage. Above that speed, throttle response is pretty anemic. I suppose it's OK to run faster if there is no traffic or other things you are going to need to avoid (animals etc.) and other circumstances, but for a generic highway speed for a long trip I don't think over 55 is safe. This is top safe speed, depending on the rider it may need to be lower.
