BMW R1200RT/R1250RT Forum

I know the RT uses a 180/55/17 on it 5.5" rim.
Now i have fitted a 190/50/17 to a 5.5" rim before and never had any problems.
I have a brand new 190 tyre that was for my Hayabusa, but its now sold.
So can i fit the 190 on the RT ?
Will the ABS ect ect ect be ok with the 190.

I suspect it will be the aspect ratio that would make any difference

Ie the 50 or 55 as this is the height of the tyre

Although the abs will have an element of error in it anyway

But the abs on these bikes uses a ring with gaps in it to detect if the wheel has stopped or not

It's the traction control that senses wheel speed from the abs sensor and makes sure ones isn't moving faster than the other

May touch the swing arm
