Sustained highway speed

I went on what I consider my first real ride today. I was in the seat 2 1/2 hours, stopping for a short stretch midway. Almost all of that was on freeways doing 75-80 mph at around 5100-5500 rpm. The bike ran great, no issues with performance OR fear( "Highway Speed Terror"). I was wondering how long I can sustain that speed?and if it is bad for the motor? Also, what do you fellas run on the highway/freeway, traffic permitting ?

Traffic permitting I run 80-85. I've never been concerned about the rpm it's running, which is over 5.000.
Keep an eye on the oil. Mine uses some, which is common for these 5,000 rpm and above.

How long can one ride at 5500+rpm? How large is the fuel tank and what is your fuel mileage at 5500 rpm?

I'll suggest 42 mpg x 5.0 gallon = about 210 miles with 20 miles on reserve, with a California gas tank & emissions plumbing.

Check your engine oil level EVERY TIME you stop riding for gas, food, or pee break!!

I rode for 13 hours straight at 5000 to 6000 rpm last week. No issues.

I have friends who have ridden from Chicago to Alaska twice doing the same thing.

Nothing to worry about.

Does chain tension affect gas mileage?

YES.
If the drive chain is too tight it will not only affect fuel mileage but chain, sprocket, wheel bearing & transmission bearing life also.

The drive chain needs to be loose enough to push the lower run Up & touch the rear tip of the rubber under slider. But Not so loose as to be allowed to touch the metal swingarm behind the rubber.

You might want to check your speedometer to learn its percent error. Mine is actually going about 74 when the meter reads 80.

I wonder if others have checked the accuracy of their speedometers.

Just got back from Red River New Mexico trip back to Texas straight thru ride, 580 miles at 82 to 85 mph all the way. had a Tent, sleeping bag, air mattress, and all the gear that goes along with a trip like that. Have done it a couple of times, same to Colorado with return ride home straight thru at a little over 650 miles. New mexico trip was around 37 to 39 mpg with all that gear. 2014 KLR 650.
Had a blast!!

Also had my speedometer checked by a New Mexico State Trooper. 65mph in a 55mph just as getting into the Cimarron Canyon. $72.00 ticket. Still had fun, love that curvy canyon road.
