in six gear equate to in MPH. I have a feeling it will be a slow ride back from the dealers with mamayama's recommended break in procedure. I was hoping one of you owners would chime in.

How did you figure that-pretty cool! Can you show the arithmetic on your calculations?Jakeboy said:Clem, you made me get out the calculator and gear ratio/final drive stuff on this one! Good question! If my numbers are correct, at 3900 rpm, you should be doing 65 mph true or 104 kph true. I based this on a rear tire aspect ratio of 70 (Bridgestone Battle Wings), wheel diameter of 17", on a 150 mm wide tire, 4.068 final drive ratio and a 6th gear transmission output ratio of .929 (which is an overdrive gear, BTW). I used the constant of 336, which is commonly used in these types of calculations. The guys that own S10's will probably give you better info, but that's what the theoretical, number crunch stuff says.
My DL 1000 had an overdrive top gear and pulled it pretty well for most of the highway speeds I typically run. I'm hoping the S10 motor has that kind of mid-range torque (or close to it), to support that overdrive 6th. Japanese engineers usually do a good job of nailing down the gearing on their bikes for most riders.
I can give you the 4000 rpm numbers, but I'm being dazzled by the Superbowl Halftime Show, which is the best I've seen! And the Packers are winning!!
Be glad to! Stay tuned. Never tried posting that sort of thing with this Apple MacBook Pro, but I'll try!Ollie said:How did you figure that-pretty cool! Can you show the arithmetic on your calculations?
holy smokes, that a great work in calculations.Jakeboy said:Clem, you made me get out the calculator and gear ratio/final drive stuff on this one! Good question!

I 've done the hard break in and I saw no noticable difference, therefore, I will continue to follow mfg suggestions. I was a little worried since the strom 650 really is moving about 50 mph at 3900 rpm in sixth, it had me worried.ptfjjj said:Don't know about the S10, but my Concours ran about 75 mph at about 4k in 6th. Take a look at the break in procedure offered by Mark Lawrence on his website, calsci.com. If you're inclined to try it, his method offers a way to get the bulk of the break in done during the first 50 or so miles. You may even be able most of it done on your way home from picking it up at the dealer if you can find a route that keeps you off of the interstate. You'll have to have fresh oil and filter available to do a change when you get home.
I haven't done the "hard" break in before, but reading Mark's engineering analysis on his site has got me thinking that I may try it this time. I've always done the baby the bike thing for 1K miles and hated it. If you want to read it, here's a link to his site: http://calsci.com/motorcycleinfo/NewBike.html#BreakIn
more than fast enough, I can't wait too test ride it in daytona next month. Makes the waiting a little less hard.fredz43 said:On my test ride 2 weeks ago, 4,000 RPM was an indicated 80 MPH. And 5,000 RPM was......... ;D
pretty much all my jap bikes have done the same, over read the MPH, but that is plenty ffast to ride it back from the dealer and stay within the guidlines of break in procedures,Gileam said:Hi there from South Africa! I do not know what the true speed will be, but according to the speedo my S10 does 32 km/1000rpm in 6th gear. In other words, at 4000 rpm it reads 128km/h or 80 mph. I know the speedo over reads, but it is exactly the same as my buddy’s Blackbird.

I screwed up on my calculation! That's what I get for watching the Super Bowl and at the same time, doing math. I didn't double the tire aspect ratio dimension and add it to the wheel diameter. I just added it once which resulted in a smaller tire circumference, and a lower speed number.motocephalic said:holy smokes, that a great work in calculations.
Now I don't have to wrry, plenty fast enough.
thanks
Don't you know guys can't do 2 things at once, it's a proven fact! )That's what I get for watching the Super Bowl and at the same time
Keeping it under 3900 RPM's for the first 600 miles. Changing the speed intervals, in other words not to drone out on the break in.Mellow said:What's the official YAMAHA break in procedure?
