I messed up and put a friends spare tire on my bike its a 180/55/zr17 instead on my 190/50/zr17 it should be fine till I change them back out next week right??

Also I saw my bike has the gear15/43 isn't 16/45 stock so why would someone go down on the rear?and how bad off is my speedo becase of this?

I did a wicked burnout in my shop with the old tire first got some pics I 'll post them soon

 

Not to worry!

1. The change in sprockets caused a change in final drive ratio from .356:1 to .349:1. A change of 1.9%.

2. The change in tire size changed the final drive ratio another 1.3%.

The total change is the sum of the two, or 3.2%

At a true ground speed of :10mph Your speedo indicates: 10.32
20mph 20.64
50 51.6
100 103.2
150 154.8

The results are 3.2% more torque (faster acceleration) and 3.2% slower top end (5mph, assuming youmotor could pull top gear all the way to red-line!).

See ya!

 

stock gearing is 16/43 not 16/45 my gearing is 15/45 and my speedo is of 10mph at 60 so it says 70 instead of 60 cause i put my gps on the bike and checked it, but with the tire your bike is gonna turn alot faster

 

turn a lot faster? you meanlike engine rpms or going in and outof curves... cuz i just got back from a ride and it kinda seems like its running a higher rpm....

 

i have a 180 dunlop qualifier on my rear and i love it ! i can get this bike on its side so far its scary ! get out there and ride and you will see what i mean ! the 180 isnt a bad thing you really wont even notice unless you know your bike and how she performs with a 190 on there

 

^^^ thtats what i ment by turns faster, i have had a 200 on mine for the past 6000 miles i would probley drop it if i went to a 180 again

 

i think you mean drag a knee

 

thanks for the info guys it seems fine....may turn a lil higher rpms or that might just be me never really noticed it before...as for the dragging knee nope don't think so my knees don't work that well now but aleast they are there.....lol anyways thanks agin

 

maybe that to..lol i bought the bike with the 200 already on it and i hated it at fist now i have gotten use to it and it aint that bad its alot more stable while riding a wheelle than a 180 is
