I got up to 70 this past weekend for the first time. Man, the bike was all over the place (it was windy).

Be safe and keep the rubber side down.

 

With the d606 knobby front tire I get speed wobbles above 70 mph. The bars sort of wiggle. Spooky.

 

get your front and rear suspension adjusted for your weight...san francisco bay 101 freeway is probably windy as it gets and the professional sag adjustments hot made a huge difference...stable at 90+ mph....when pavement conditions are poor...with lot of deep cracks and lines on the road...it can get little wiggly...but, still able to cruise at about 70 mph...got a scotts steering damper installed yesterday just to keep it extra stable...

 

i cruise at 70-75mph on my sf quite a bit, little high on the rpm's but the motor seems happy

 

Handling and wind resistance are the limiting factors on top speed in my experience. Between those two items, you'll never get to red-line in 6th gear.

 

I usually ride 75 to 80 occassionally to keep up with traffic. Im thinkin my speedo is off. I've got my gearing at 15/39 right now to keep the engine revs down. 65mpg is about 6500 rpm.

 

If your asking about speeds with motor break-in.....Just run it like you stole it, it will be fine

 

It seems sometime you feel the bike will throw u away( wigley)

 

Ive gotten mine to indicate 94mph. I frequently ride at 80 mph (indicated) for 5 to 7 miles on I-5 on the way to work. I weigh 186 pounds in my under-ware.

I switch to reserve at 90 miles on the odometer. I went 115 miles between fill-ups, once.

 

I must have a bike made on a monday, cause the best I have seem from mt SF is 78 indicated, I wont take my bike on the interstate for nothing I did once just to see what it had I ran 8 miles to the next exit and took it. You guys seeing 90 must weight in at 75# soakin' wet....
