Itis possible to lost some mph on top speed when changing front tire???

I pass from OEM stock tire to razr2 22in and now I top to 70mph (113kph) and before change it was to 73-74(119-120)

And the only change from last summer it's sway bar and front rim-tire

and it's not valve clearence, it adjust last week

Thanks guy!!!!

my only guess is that it is due to the tire being a heaver

WiZkY,
Are you running the recommended tire pressure?

yes, 5-6 all around

I run 20in rear!!!! with stock sprocket

or it's just the wind!!! I was deported to left and right when i test it

Weight will slow you down a bit. Do you weigh the same as last summer?

Would be intersting to swap tires and run back to back to see how much change in mph a taller/heavier tire affects the top speed.

I found the stock tires and rims were really good for top speed. When I switched to OMF rims and razr2 fronts and razr rears the extra weight slowed me down pretty noticeably. I would say I lost about 8-10 km/h.

wight will only slow u down if ur going up hill. it might be that traction is down a lil in the rear due to the sway bar.

computer

If your running a computer to calculate your speed , did you re calibrate it for your new taller tires that will be a few rpm's less ?
:xx:

 

[WiZkY]

yes, and compare to GPS!!!

I'd chalk it up to wind.
