My bike need two new tires. The manual says 120/60 zr17 and 170/60 zr17. Neither of the tires currently on the bike are these sizes. Since these are also hard sizes to find I was wondering what is the range that works?

thanks

like 70 in front.... im not sure the back(its a 190 now)

 

Yes, 120/70-17, 120/65-17 or 120/60-17 for the front and 180/55-17 for the rear. If you want quicker steering, go with the 60 or 65 series in the front.

 

Quicker steering vs.??? more stability?
thanks for the advice

 

Yep, that's the dilemma. The 65 series is the happy mediumor get a steering damper and go 60 series. The 636's come with the 65 series front.
