I did 3 days of traveling this weekend of 120 miles a day. I enjoyed being on my bike and the weather was great. While I was riding I noticed that my speed was on average a steady 80mph. I started thinking will this hurt the bike?
So my question is, what is your highway speed?
I usually do somewhere between 60 and 75 mph on the highway. I doubt if doing 80 mph will hurt the bike. That's around 6500 rpm on a standard geared GS.
Don't know mph, but bike will sit at 6k rpm In 6th all day long. Of course, rider could do with a rest evey hour :-) that's 120kph.

I find that my bike is comfortable between 70-80mph
hmm my bike dose 6500 rpms doing about 60-65. mph (6th gear)
7000-7500 rpms @ 70-85
and i topped it out at 110 or so around 8500- 9000 rpms

stock sprockets?
in 5th gear at 6k rpms i'm at 70mph, 6th gear at 6k rpm i'm at 80
yeah i think they are stock... i know i didnt do shaZam! to it lol
hmm...i didn't do anything to mine either..looks like one of us isn't stock LOL
actually

looks like you are one teeth up in the back/down in the front
idk if that chart is correct lol...
Just curious Norway- why? Because of the 140mph on the chart? If so, it was probably done on a dyno, where wind won't slow down the bike.
Norway, the chart is pretty accurate - accurate enough.
6th gear at 6k rpm is a tad above 120kph. Close to 80mph.
4th gear at 9k rpm is 140kph which is roughly 87.5mph and that's pretty close to what the chart shows. 4th gear at 4k rpm is 60kph (37mph) and is what the chart shows.
If your bike is not getting this and is doing 6,500rpm at only 65mph (104kph) in 6th gear then you do not have stock sprockets, or you're having a lot of clutch slippage on the go, or your speedo is all bugger to hell and is reading way way low, or you have a very small rear tire. My money is on sprockets not being stock.
At 65 and 6th gear you should be doing around 5k rpm, which is what the chart closely resembles.
Michael
Yeah at 100kph I'm sitting just above 5k. The bike itself should sit happy at any speed as long as the rider can stand it and it doesn't burn all it's oil up.
Rayson,
cool chart, those specs show what my bike does and mine gears are stock. Good point to check the oil after all that running. I'll let you all know what I find.

I did get my bike up to 110mph but I began to get the wobbles in the handle bars so I backed it back down. Get bike though I need some music next time.
ill go count my teeth and let you know what i come up with...

I just take mine out to count them. :icon_lol: :icon_lol: :icon_lol:

I wonder if the previous owner of my bike put a 15 tooth on my front sprocket? I've never actually checked and just assumed it was stock 16 tooth. I've made several trips from Gainesville to Tampa and I could've sworn my 80 mph was closer to 7000 on the tach. I'll check on the way home tonight.
I generally do 75-80 on the Interstate and felt the bike was kind of buzzy, especially at that RPM for 2 1/2 hours. It got me thinking of switching over to a SV650 at some point in the future, but if it would probably be a little smoother at 6K.
alright well i just went for a ride and here is the update:
6th gear at 60-65 mph is at 5500 rpms.
70 it said 6500 or so
80 was 7000
saw 3 cops and went back to 55 mph speed limit lol
Norway, you do not have stock sprockets. At 70 you should be around 5,500 as it shows on the chart and my stock bike agrees with.
Michael
i think you might be right, should i count out my front sprockets or rear in this case... ?
Start with the rear cause it's easier. But only if it bothers you or you really want to know.
Michael
Both.
well my rear sprocket is 39-520 (39 teeth) front is gonna have to wait until i have more time.

Mine about that too. Just checked on ride home. 3000 rpm = 34mph, 4000rpm = 45 mph, 5000 rpm = 56-57, 6000 rpm= 68-69mph, 7000 rpm = 80.
Betting I have a 15 tooth. I would love to drop the highway rpms, so the next chain and sprocket change should yield a pleasant result if I switch to the 16.
Switching to a 16 tooth front will bring it back to Stock.
Norway, seeing as your rear sprocket is stock size, you'll now need to investigate the front.
Michael
With an indicated speed of 110kph, which is actually 102 kph, my tach around 5500. Its stock as rock. When did Suzuki start putting the slow speedo's on the GS?
