3000k RPM's at 60 mph?? Is that normal

[screamineagle]

Just wondering if 3k rpms is normal for 60 mph in 5th gear. Have an xb1200r. Just seems a little high. Runs great at that speed just wondering if my sprocket is larger than normal.

 

[mart7]

no that is normal

 

[onelogue]

Yup normal. I thought the same thing so no worries

Has anyone tried one of the 29 tooth pulleys on the tranny side? I'd like to know how much of a difference it makes. I do a lot of highway riding and I'd like to bring down the revs some.

bye bye torque, but if you do that you will need a new belt too. What speed are you normally at on the highway cause 5th gear lower than 2500 rpm is borderline lugging the engine.

 

[BRomanowski]

Well I'm usually cruising along at 75-80 so I'm at at least 4k most of the time. Would the extra 2 teeth make that big of a difference?

 

[onelogue]

Hmm hard to tell how much a difference it will make. You will get better gas mileage.
I ride about 75-80 too. 3 to 4 k is pretty normal rpm range for our bikes. I rode three ours on average 80 to 90mph, and my bike handled it great.

If you do the mod. post your average gas millage; I do mostly highway driving too and currently get 50-55 mpg. I would guess that it would decreas your RPM's about 500.

Do a chain conversion. Then you can play with gear ratios all day long. There isn't many options with pulleys.

FreeSpirits makes a pulley kit for speed and one for torque.

Only a 10% increase. so if your top speed is 140. it will increase to 154. With that in mind maybe you could expect a 10% increase in gas mileage. Not worth it in my opinion. Its about 700 us dollars.

Mine runs right around 3k at 60 in 5th!
