So my question is about the tires (not for t he R model).
The dimensions will be 120/70-19 front; 170/60-17 rear.
What options does someone have for on/off purpose. Most of the options in this category are with a rear tire of size 150/70-17 .
The 170/60 sounds to me like a problematic size. It reminds me like the smart move of the Yamaha TDM with the 18" rims and the minimal option of tires.
