Hello everybody, this is my first post. My 2007 Bonneville T-100 and I are getting to know each other and I am wondering if 4000 RPM is normal for riding at 100km/h on the highway. Seems like it would devour the petrol on a long trip. Thanks.

That's about right for the stock 18 tooth front sprocket. I changed to a 19t to lower my cruising revs. 60 mph (100 kmh) is 3600 now. Well worth the 20 bucks for me.

it's really not as bad on the gas as you'd think. I get ~43-45mpg (us) as long as I keep the speeds down to no higher than 70. up over 80, gas mileage starts to drop.. to ~37mpg.

4000K on the highway? You must ride slow...mine stays around 6K

Sideshow,

You have to remember this is a parallel twin not a big thumping V-twin .The motors love to rev. If you open the throttle from a take off you will notice the motor dosen t come on strong to at least 4000 rpm and this is where the motor is happy to be at, instead of lugging around.

i just checked my mileage and most of it was around town mileage and if my calculations are correct, i got right at 51 mpg. Now I'm not really a hot rodder, but I love to short shift from stop lights cuz my pipes sound reaaly cool. So you can have fun and get good mileage.:

The r's are rite on!! As said these motors like to rev! Your MPG is rite on as well!
Just checked mine last fill- 50 MPG. Thats telling you the bike is running rite on. You wont get much better than that! 4 yrs now & still getting avg 45-50 mpg. Thats where the bike should be running as its supposed to! Roll the right hand & things will change a little! I couldnt help it when it was 1-2 yrs old!! She's nice & loose now tho- like a swiss watch!!

Approx 4000rpm at 60? That's about where I'm at with my 03 790cc with 17 tooth countershaft sprocket. (actually, I show 3700 at 60 mph, but I've found that my speedo is wildly optimistic, showing 60 when I'm running 55).

The beauty of chain drive and sprockets is the fact you can easily and inexpensively change final drive ratios. However, the little 790cc engine will run all day at 4500-5000 (or more) rpm. Matter of fact, that mill seems to thrive on revs. It should, since it is a short stroke twin with dual overhead cams. Mine has spent the majority of its life running a 17T sprocket, and will end its life running a 17T.

As a point of comparison, my 1991 BMW R100GS is a 1000cc pushrod twin. She is geared low, since intended for on road/off road, almost like my T100, showing 3750rpm at 60mph. It is a larger engine, with a longer stroke, but I've also run this bike mile after mile at 5000rpm ( like across the state of Nebraska on the Interstate) and she runs as strong today at 111,000 miles as she did at (whatever mileage).

Although the new BMW manuals don't provide the information, my first Beemer (1985 K100RS) provided some neat data. Things like " ...... redline = 8750rpm, maximum permissable continuous rpm = 8450rpm. This gave you a good idea as to whether you were (or not) hurting the bike by continuous high speed riding. They don't publish this or top speed info anymore. Sad!

On the 18th tooth sprocket it's around 4k at 70 MPH in 5th gear, 4k at 60 MPH in 4th gear.
